Integrated Pest Management Australia: Complete IPM Guide

Integrated Pest Management (IPM) is a structured, evidence-based approach to pest control that combines multiple strategies rather than relying on repeated pesticide applications alone. By working with your growing environment — and, where appropriate, with nature itself — IPM reduces pest pressure more sustainably, lowers the risk of chemical resistance, and protects beneficial organisms in your growing space.

At Green Genius, we stock a range of monitoring tools, biological inputs, and targeted treatments to support every stage of an IPM program. Whether you are growing in soil, coco, or a hydroponic system, the principles below apply.

The IPM Process

A sound IPM program follows a repeating cycle:

Identify → Monitor → Prevent → Correct Environment → Mechanical Control → Biological Control → Targeted Treatment → Reassess

Each step informs the next. Skipping identification and moving straight to treatment is one of the most common — and costly — mistakes growers make.

Identify the Pest Before Treating It

Correct identification is the foundation of effective IPM. Treating for the wrong pest wastes money, may harm beneficial organisms, and can allow the actual infestation to worsen. Use a hand lens or jeweller's loupe to inspect leaf undersides, growing media surfaces, and new growth before selecting any product.

The table below is a quick-reference guide based on pests supported by current Green Genius product information. Pests for which we could not verify product support have been omitted.

Pests including scale, mealybugs, caterpillars and shore flies have been omitted from this opening table where current Green Genius product information does not provide enough verified detail for a concise treatment recommendation.

The IPM Control Hierarchy

Monitoring and Early Detection

Early detection is one of the most effective ways to keep a pest problem manageable. A small population identified in week one is far easier to address than an established infestation discovered in week four.

Sticky traps are the cornerstone of any monitoring program. Yellow sticky traps attract a broad range of flying pests including whiteflies, fungus gnats, aphids, and thrips. Blue sticky traps are particularly effective for thrips monitoring. Place traps at canopy height and near the growing media surface, and inspect them at least weekly. Record the number and type of insects captured — this data helps you track whether a population is growing, stable, or declining in response to treatment.

Green Genius stocks several sticky trap options:

• Bugs for Bugs Yellow Sticky Traps — biodegradable, non-toxic, with an integrated counting grid
• Bugs for Bugs Blue Sticky Traps — specifically suited to thrips monitoring
• Sticky Traps (Yellow) — all-weather adhesive, indoor and outdoor use
• Insect Glue Traps 10-pack — suitable for a range of flying insects

Important: Sticky traps are monitoring tools. They will capture flying adults and help you gauge pest pressure, but they will not control an established infestation on their own. Use trap counts to guide your response, not as a substitute for it.

Beyond traps, regular hands-on inspection is essential. Use a hand lens or jeweller's loupe to examine leaf undersides, growing tips, and the surface of your growing media at least once or twice per week. Inspect the soil or media surface for larvae, eggs, or unusual activity. Keep a simple log of what you find and where — patterns across inspections are often more informative than any single observation.

Quarantine and Prevention

Many pest introductions can be prevented or detected before they spread. Before any new plant, cutting, or propagation material enters your growing space, inspect it thoroughly under magnification. Look at leaf undersides, growing tips, and the root zone where possible. If you are unsure, quarantine new material in a separate area for an appropriate observation period before introducing it to your main growing space.

Good hygiene practices significantly reduce the risk of pest establishment and spread:

• Clean and disinfect tools between plants and between growing areas
• Remove dead leaves, spent flowers, and decaying plant material promptly — these provide shelter and breeding sites for many pests
• Avoid moving growing media, pots, or equipment between areas where a pest has been identified
• Inspect propagation material carefully before use — cuttings and seedlings can carry pests or eggs that are not immediately visible
• Keep walkways, trays, and growing surfaces clean and free of debris

Prevention is not glamorous, but it is the most cost-effective pest management strategy available.

Environmental Management

Many common pests thrive under specific environmental conditions. Adjusting your growing environment will not eliminate an established infestation on its own, but it can significantly reduce the conditions that allow pest populations to build and persist.

Temperature and humidity are particularly important. Spider mites, for example, reproduce rapidly in hot, dry conditions. Thrips and fungus gnats are associated with specific humidity and moisture profiles. Maintaining appropriate temperature and relative humidity for your crop — and avoiding extremes — removes one of the key drivers of rapid pest population growth.

Airflow matters too. Stagnant canopy zones create microclimates that favour certain pests and fungal issues. Good air circulation across and through the canopy reduces these pockets and makes the environment less hospitable to pests.

Moisture management is critical for fungus gnat and shore fly control. These pests are strongly associated with persistently wet growing media, standing water in trays, and algae growth on surfaces. Allowing the top layer of your growing media to dry between waterings — where your crop allows — and eliminating standing water and algae from trays and surfaces removes the conditions these pests depend on.

Green Genius stocks a range of environmental management equipment to help you maintain optimal conditions:

• Environmental Controls — controllers, monitors, and automation
• Environmental Equipment — fans, climate tools, and related accessories
• Irrigation Systems and Parts — for precise moisture management

Mechanical and Cultural Control

Physical intervention is often underestimated as part of an IPM program. Removing heavily infested leaves or pruning damaged growth reduces the pest population directly and eliminates the plant material that is most likely harbouring eggs and juveniles. This is particularly useful early in an infestation before populations have spread widely.

Practical mechanical control steps include:

• Remove and dispose of heavily infested or damaged leaves — do not compost infested material; bag and bin it
• Prune damaged or dying growth to reduce pest habitat and improve airflow
• Clean trays and saucers regularly to remove standing water, algae, and debris
• Physically remove visible pests where practical — a damp cloth or soft brush can be effective for small, localised populations
• Wipe down growing surfaces, walls, and equipment in affected areas

Mechanical control is most effective when combined with environmental correction and, where appropriate, biological or targeted chemical control.

Biological Control

Biological control uses living organisms — typically predatory insects or mites — to reduce pest populations. When used correctly, biological control can be highly effective and avoids the residue and resistance concerns associated with repeated pesticide use.

Live-beneficial availability can change quickly. Check the current Green Genius range or contact us before planning a release. Common biological-control organisms include Phytoseiulus persimilis, Cucumeris, Montdorensis, Stratiolaelaps/Hypoaspis, Dalotia coriaria and Orius spp. Whether supplied by Green Genius or another specialist supplier, the following general principles apply:

• Identify the target pest correctly before selecting a beneficial — different predators target different pests and life stages
• Understand where the predator operates (canopy, growing media surface, root zone) and match this to where your pest is active
• Consider whether you are using beneficials preventatively (low-level introduction before pest pressure builds) or reactively (into an active infestation) — release strategies differ
• Do not release beneficials into an environment where incompatible pesticide residues are present

Warning: Previous pesticide applications may affect beneficial organisms. Check compatibility before release. Many commonly used insecticides, miticides, and fungicides have residual activity that can kill or impair predatory insects and mites. Always confirm the re-introduction interval for any product used before releasing beneficials.

Spider Mite IPM Strategy

Spider mites are one of the most common and persistent pests found in indoor gardens, hydroponic systems and protected growing environments. A successful spider mite strategy should combine accurate identification, population reduction, environmental management, biological control where appropriate and targeted treatment when required.

How to Identify Spider Mites

Spider mite damage often begins as fine pale stippling or speckling across the leaf surface. As populations increase, leaves may progressively yellow, dry or lose vigour. Inspect the undersides of affected leaves closely for mites, eggs and fine webbing.

A hand lens or magnifier can make identification easier. Do not assume every mite found in a garden is a pest, as predatory and harmless mites can also be present.

Step 1: Inspect and Monitor

• Inspect the undersides of affected leaves.
• Check nearby plants rather than treating the visibly damaged plant in isolation.
• Look for adults, immature mites, eggs and webbing.
• Mark heavily affected plants so they can be checked again.
• Continue monitoring after treatment rather than assuming the infestation has been eliminated.

Step 2: Reduce Pest Pressure

Where practical, remove badly infested or heavily damaged leaves. Remove dead plant material from the growing area and consider isolating affected plants where this can be done without spreading mites further.

Clean the immediate growing area, trays and equipment, and avoid moving directly from heavily infested plants to clean plants without considering tools, hands and clothing as possible transfer routes.

Step 3: Review the Growing Environment

Environmental management is not a replacement for treating an established infestation, but reducing plant stress and eliminating stagnant canopy zones can improve the overall IPM program.

• Maintain adequate air circulation through and around the canopy.
• Check for unusually hot areas around lighting or equipment.
• Monitor temperature and humidity rather than relying on room feel.
• Avoid allowing dense foliage to create inaccessible stagnant areas.
• Check irrigation and root health so plants are not unnecessarily stressed.

Step 4: Biological Spider Mite Control

Predatory mites can form an important part of spider mite IPM. Phytoseiulus persimilis is a specialist spider mite predator commonly used against active spider mite populations. Other predatory mite species may be used in preventative programs or under different growing conditions.

The important point is to introduce the correct predator for the pest and the situation. Biological control should not simply be added on top of a pesticide program without checking compatibility.

Important: Check recent pesticide, oil and soap applications before releasing predatory mites. Some residues can kill or suppress the beneficial organisms you are introducing.

Read the Green Genius Guide to Predatory Mites

Step 5: Spider Mite Treatment Options

When sprays or miticides are required, choose a product specifically suited to the identified pest and follow the current product label. Thorough coverage is particularly important with contact products because mites and eggs frequently shelter on leaf undersides.

Pesticide reminder: Always follow the current Australian product label, including permitted crops, application directions, protective equipment and withholding periods. Do not assume that a product suitable for one mite species is suitable for every mite species.

Step 6: Reassess the Infestation

IPM does not finish when a treatment is applied. Reinspect the crop and surrounding plants, looking for surviving mites, fresh eggs, new stippling and renewed webbing. The aim is to determine whether the pest population is actually falling.

If mites remain, reconsider identification, spray coverage, environmental conditions and whether the next step should be biological control, another labelled treatment or removal of heavily affected material.

Thrips IPM Strategy

Thrips require a broader approach because different stages of their life cycle can occupy different parts of the growing environment. Feeding stages are commonly found on foliage and new growth, while other stages may occur away from the visible canopy or around the growing medium.

How to Identify Thrips

Typical signs can include silvery or scarred patches on leaves, distorted young growth, small elongated insects moving across foliage and dark spotting associated with feeding. Adults may also be detected on sticky monitoring traps.

Step 1: Monitor the Canopy

• Inspect new and damaged leaves closely.
• Check leaf undersides and folds in new growth.
• Look for elongated adults and smaller immature stages.
• Use sticky traps to monitor flying adults and population trends.

Blue Bugs for Bugs Sticky Traps are specifically positioned as a thrips monitoring tool. Yellow Sticky Traps can also help monitor thrips and several other flying pests.

Step 2: Reduce Population Pressure

Remove badly damaged material where practical, clean dead leaves and debris from the growing area, and inspect nearby plants. Heavy infestations are easier to manage when the total pest population is reduced before biological controls or targeted sprays are relied upon.

Step 3: Biological Control for Thrips

Thrips IPM can use different beneficial organisms to target different pest stages. Depending on availability and the growing system, options may include:

• Cucumeris predatory mites for immature thrips on foliage.
• Montdorensis predatory mites for canopy pest stages.
• Orius predatory bugs for mobile thrips stages.
• Stratiolaelaps/Hypoaspis soil-dwelling predatory mites for pest stages occurring around the growing medium.
• Dalotia coriaria rove beetles as part of a soil-surface biological-control program.

Selection should be based on the pest stage, growing environment and current supplier instructions. Do not assume that combining every available predator will provide a better result.

Step 4: Targeted Thrips Treatments

Where beneficial insects or mites are being used, check treatment compatibility before spraying. Direct contact or residues can undermine a biological-control program.

Fungus Gnat IPM Strategy

Fungus gnats require two different monitoring and control approaches: the flying adults above the growing medium and the immature stages developing within or around moist media. Treating only the adults can leave the developing population untouched.

How to Identify Fungus Gnats

Adults are small, dark flies commonly seen walking or flying around pots, propagation areas and moist growing media. Yellow sticky traps can help confirm their presence and show whether adult numbers are rising or falling.

Step 1: Correct Excess Moisture and Sanitation Problems

• Review irrigation frequency and avoid unnecessary saturation.
• Remove standing runoff water.
• Clean trays, floors and drains.
• Remove algae and decomposing plant material.
• Inspect irrigation leaks and continuously wet areas.

Do not deliberately dry living soil or moisture-sensitive plants beyond their appropriate range. The objective is to remove unnecessary excess moisture, not create drought stress.

Step 2: Monitor Adults

Bugs for Bugs Yellow Sticky Traps provide a simple way to monitor adult fungus gnats. Place monitoring cards close enough to the crop or growing-medium surface to detect activity and check them regularly.

Remember: Sticky traps primarily address and monitor flying adults. They do not by themselves remove all larvae developing inside the growing medium.

Step 3: Biological Control in the Growing Medium

Biological options for fungus gnat larvae can include soil-dwelling predators such as Stratiolaelaps/Hypoaspis predatory mites and Dalotia coriaria rove beetles. These organisms operate around the growing-medium surface and root zone rather than flying around the canopy.

Use release instructions supplied with the biological control and check recent pesticide residues before introducing live predators.

Step 4: Target Fungus Gnat Larvae and the Root Zone

Fungus Gnat IPM Sequence

1. Monitor flying adults.
2. Inspect the growing medium.
3. Correct unnecessary moisture, algae or sanitation issues.
4. Target larvae rather than relying only on adult traps.
5. Use biological controls or an appropriately labelled root-zone product where required.
6. Continue monitoring until adult numbers remain under control.

Aphid IPM Strategy

Aphids commonly gather around soft new growth, stems and leaf undersides. Signs can include clusters of small insects, curled or distorted leaves, sticky honeydew and pale shed skins.

Inspect and Reduce the Population

• Inspect growing tips and fresh foliage.
• Check leaf undersides.
• Remove heavily colonised plant material where appropriate.
• Physically remove small colonies where practical.
• Use sticky monitoring cards to track winged adults entering or moving around the growing area.

Yellow Sticky Traps are suitable for monitoring aphids as part of a broader IPM strategy.

Aphid Treatment Options

Contact treatments depend on coverage. Inspect the plant again after application and continue monitoring new growth rather than treating once and assuming the colony has been eliminated.

Whitefly IPM Strategy

Whiteflies are usually noticed as small pale adults that lift from foliage when plants are disturbed. Immature stages can be found on leaf undersides, and heavier populations may be associated with honeydew, leaf yellowing and declining plant vigour.

Monitor Whiteflies

• Inspect leaf undersides for immature stages.
• Check new and middle canopy leaves.
• Use yellow sticky traps to detect and monitor flying adults.
• Remove heavily affected leaves where practical.
• Keep dead plant material and weeds away from controlled growing areas.

Bugs for Bugs Yellow Sticky Traps are listed for monitoring whiteflies as well as aphids, fungus gnats and thrips.

Whitefly Treatment Options

• AzaMax — current listing includes whiteflies.
• NatraSoap — contact insecticidal soap listed for whiteflies and other soft-bodied insects.
• Green Cleaner — contact treatment whose current listing includes whiteflies.
• OGS Neem Oil — current listing includes whiteflies.
• Zero Tolerance — botanical contact product whose current listing includes whiteflies.

Sticky traps are valuable for monitoring adults but should normally be combined with inspection and treatment of the plant itself when an established infestation is present.

Broad Mites, Russet Mites and Other Pest Mites

Not every plant-feeding mite behaves like a common spider mite. Broad mites, russet mites and other microscopic mites can be difficult to see without magnification, and their damage can sometimes resemble nutrient problems, environmental stress, plant disease or distorted new growth caused by other factors.

Correct identification is particularly important before choosing a treatment.

Broad Mites

Broad mites are extremely small and can affect young developing tissue. If broad mites are suspected, inspect distorted growth closely with adequate magnification before selecting a pesticide or biological control.

Russet Mites

Russet mites are also extremely small and may require substantial magnification for confirmation. Do not automatically treat unusual leaf discolouration or distorted growth as russet mite damage without inspection.

Verified Green Genius Options

• Green Cleaner — the current Green Genius listing specifically includes broad mites and russet mites.
• Kill-A-Mite — the current listing includes broad mite, tomato russet mite and several other mite species. Use strictly according to the current Australian label and withholding requirements.
• NatraSoap — current listing covers various soft-bodied mites; confirm the particular pest and permitted use before application.

Identification first: A product that controls spider mites does not automatically control every mite species. Use magnification, confirm the pest and check the current product label before treatment.

Root-Zone Pest Management

Some pest problems develop below the canopy in the growing medium, root zone, runoff trays or other persistently moist parts of the growing system. Above-ground symptoms alone may not clearly distinguish a root-zone pest from overwatering, root disease, poor oxygenation or nutrient problems.

What to Inspect

• The surface of soil, coco or other growing media.
• Drainage holes and runoff trays.
• Roots that can be safely inspected.
• Algae and continuously wet areas.
• Dead organic material around pots and trays.
• Adults flying or walking around the media surface.
• Any obvious insects or larvae within the upper growing-medium layer.

Fungus Gnats

Fungus gnats are one of the most common root-zone pests. Monitor adults using yellow sticky traps, but direct the main control program toward the growing medium and larval stages.

Current Green Genius options include NO GNATS, NL Scarid 10, Scarid Fly Drench, AzaMax where permitted by the current label, and HPO Karanja Meal as an IPM-supporting living-soil amendment.

Shore Flies

Shore flies can be confused with fungus gnats, but they are more strongly associated with algae and wet organic residues than direct root feeding. Reducing algae, persistent surface moisture and standing water is central to management. Where a pesticide or biological control is considered, confirm the pest first and follow current supplier or label guidance.

Root Aphids

Root aphids should not be confused with fungus gnat larvae. Confirm the pest before choosing a treatment. Check roots and growing media closely, and inspect for insects around drainage holes and lower stems.

Ed Rosenthal's Zero Tolerance currently lists root aphids among its target pests. Follow the product directions and check compatibility with any biological organisms already present in the growing system.

Biological Root-Zone Control

Soil-dwelling beneficial organisms can form another layer of root-zone IPM. Depending on the identified pest and current availability, commonly used options include:

• Stratiolaelaps/Hypoaspis predatory mites for fungus gnat larvae and other small soil-dwelling pest stages.
• Dalotia coriaria rove beetles for fungus gnat larvae and other suitable pests around the growing-medium surface.

Live-beneficial availability changes quickly. Check current Green Genius stock or speak with a specialist supplier. Biological organisms work best when introduced into a suitable environment and when incompatible pesticide residues are absent.

Moisture and Sanitation Management

Root-zone IPM should also address conditions that allow pest populations to persist:

• Correct unnecessary overwatering.
• Repair irrigation leaks.
• Remove standing runoff water.
• Clean trays and drains.
• Control algae.
• Remove decomposing plant material.
• Inspect propagation areas regularly.
• Quarantine incoming plants where practical.

Persistently wet media, algae and excess surface moisture can strongly favour fungus gnat and shore fly populations. Living soil should not be deliberately dried excessively simply to control fungus gnats; maintain appropriate soil moisture while addressing persistent saturation, standing water and sanitation problems.

Root-Zone IPM Quick Guide

Do not diagnose from the leaves alone. Root pests, overwatering, poor root-zone oxygen, nutrient problems and root disease can create similar above-ground symptoms. Inspect the growing medium and roots before deciding on treatment.

IPM Spray and Treatment Comparison

The table below summarises current Green Genius pest-control products to help you select the right tool for your situation. Always read the product label before use. Beneficial-insect compatibility information is based on current product descriptions only — where compatibility is not stated, check with the product manufacturer or your beneficial supplier before use.

Neem, Oils, Soaps and Botanical Treatments

Neem-based products, insecticidal soaps, garlic extracts, and other botanical treatments occupy an important middle ground in an IPM program — they are generally lower in residue risk than synthetic pesticides and are often compatible with organic growing systems, but they are not without impact on the broader growing environment.

Neem Products

Neem products are derived from the neem tree (Azadirachta indica). Depending on the formulation, they may contain neem oils or purified neem-derived actives such as azadirachtin. Their labelled modes of action and permitted uses vary by product, so follow the current product directions. Green Genius currently stocks:

• OGS Neem Oil — emulsified for easy mixing; follow the current product directions for permitted foliar or soil use.
• Mite Rid — cold-pressed neem oil concentrate specifically formulated for spider mite control.
• AzaMax — APVMA-registered organic insecticide using purified azadirachtin (no neem oil carrier). Certified organic input for ACO growers.

Karanja Products

Karanja oil and meal are derived from Pongamia pinnata and are used in organic growing as a soil amendment and pest deterrent. Unlike neem oil, karanja has a lower odour profile and is well suited to indoor use.

• HPO Karanja Meal — mix into soil or apply as a top dressing to support fungus gnat suppression and soil biology.

Insecticidal Soaps

Insecticidal soaps work by disrupting the cell membranes of soft-bodied insects and mites on contact. Their activity is primarily by contact, which can reduce persistent exposure compared with some residual products, but they can still affect beneficial organisms if applied directly. Check product-specific compatibility before combining them with live biological controls.

• NatraSoap — organically registered; effective against aphids, thrips, mealybugs, whiteflies, leafhoppers, and mites. Product information describes relatively low impact on beneficial insects; avoid direct spraying of released beneficials and verify compatibility with your beneficial supplier.

Garlic and Botanical Sprays

• Bio Green Garlic — high-allicin garlic and ginger extract. Apply as a foliar spray or root drench. No residual smell or taste per product description.
• OGS IPM Spray — multi-ingredient botanical spray including neem, silica, saponins, fermented turmeric, aloe, and kelp. Made in Australia.
• Ed Rosenthal Zero Tolerance — essential oil aerosol (cinnamon, rosemary, clove, thyme). Fast-evaporating with no sticky residue.

Important: Natural does not automatically mean harmless or compatible with beneficial insects. Neem oil, essential oils, and insecticidal soaps can all affect predatory mites and other beneficial organisms if applied directly or if residues are present at the time of release. Always check compatibility with your beneficial supplier before combining spray treatments with a biological control program.

Sticky Traps and Monitoring

Sticky traps are one of the most practical and cost-effective monitoring tools available to growers. Used consistently, they provide an ongoing record of pest activity that helps you detect problems early, track population trends, and assess whether treatments are working.

Using Trap Counts Effectively

The value of sticky traps comes from consistent, recorded monitoring rather than occasional inspection. Count and record the number of each pest type captured each time you check your traps, using a consistent inspection schedule. A rising count indicates a growing population; a stable or falling count after treatment suggests the program is working. Replace traps when they are full, dirty, no longer sticky or according to the product instructions.

Sticky traps capture flying adults. They do not capture eggs, larvae, pupae, or non-flying stages. For pests like fungus gnats, thrips, and spider mites, trap counts reflect only part of the population. Use trap data alongside direct plant inspection to build a complete picture.

---

Cleaning and Sanitation

A clean growing environment is one of the most effective pest prevention tools available. Many pest populations persist between cycles because eggs, larvae, or adults survive in debris, on equipment, or in residual moisture. Thorough cleaning between cycles — and regular maintenance during a cycle — significantly reduces this risk.

Grow Space Cleaning

• Remove all plant debris, dead leaves, and spent growing media from the grow space promptly — do not allow it to accumulate.
• Wipe down walls, floors, and surfaces with an appropriate cleaner between cycles. Pay attention to corners, drainage channels, and areas where moisture collects.
• Clean floors and drains regularly to remove organic matter that supports fungus gnat and shore fly populations.
• Check and clean air-intake areas — pests and spores can enter through intakes and accumulate on filters.

Trays, Pots and Equipment

• Wash trays and saucers between cycles to remove algae, salt deposits, and organic residue.
• Clean reusable pots thoroughly before reuse — root residue and old media can harbour pest eggs and pathogens.
• Clean and disinfect pruning tools, scissors, and other hand tools between plants and between growing areas.
• Professor's Nutrients Resin Clean — citrus-based cleaner for tools and equipment. Dissolves resin from trimmers, scissors, and pruners.
• We The Wild Leaf Cleaning Gloves — microfibre gloves for removing dust and debris from leaves. Reusable and machine washable.

Irrigation Equipment

• Flush and clean irrigation lines, drippers, and reservoirs between cycles to remove biofilm, algae, and salt deposits.
• H&G Drip Clean — potassium-based drip-line cleaner. Prevents salt crystals and sediment; safe for roots and microbes.
• GT Oxy Plus — 50% hydrogen peroxide used for nutrient-solution oxygenation, root-zone hygiene and hydroponic system sanitisation at different labelled rates. Handle with appropriate PPE and do not combine with beneficial microbes unless product guidance specifically allows it.
• Flairform Pythoff — hydroponic water treatment added to nutrient solution as directed to support root-zone hygiene and help control algae/slime and plumbing build-up. Current product information states it can be used from seedling to harvest. Do not combine with hydrogen peroxide or beneficial microbial additives.

Propagation Areas

• Start every propagation cycle with clean trays, clean propagation media, and clean tools.
• Inspect all cuttings and seedlings before they enter the main growing space.
• Keep propagation areas physically separate from areas with known pest pressure where possible.

Note: Follow each sanitising or water-treatment product label carefully. GT Oxy Plus and Flairform Pythoff can both be used in nutrient solution at their specified rates, but they are not general-purpose foliar disinfectants. Do not spray them onto foliage unless the label specifically permits that use.

---

Root Disease Versus Pest Problems

Above-ground symptoms such as wilting, yellowing, slow growth, and leaf drop can result from a range of causes — not all of them pest-related. Diagnosing from leaf symptoms alone without checking the root zone is one of the most common errors in plant health management.

Similar above-ground symptoms can result from:

• Root disease — root pathogens can be associated with browning, soft or slimy roots, poor root integrity and odour. Root colour alone is not diagnostic because nutrients, organic inputs and media can stain otherwise healthy roots.
• Poor oxygen in the root zone — overwatering, compacted media, or blocked drainage reduces oxygen availability and causes root stress that mimics pest damage.
• Overwatering — persistently wet media stresses roots and creates conditions for both root disease and fungus gnat infestations simultaneously.
• Nutrient issues — deficiencies and toxicities produce leaf symptoms that can resemble pest damage. Check pH and EC before assuming a pest cause.
• Root pests — fungus gnat larvae, root aphids, and other soil-dwelling pests cause root damage that manifests as above-ground stress.

Always inspect the root zone directly before concluding that above-ground symptoms are pest-related. Where the growing system allows it, inspect roots without causing unnecessary damage. Healthy hydroponic roots are often white to cream and firm, although nutrient solutions, organic inputs and media can alter root colour. Soft, slimy, deteriorating or foul-smelling roots warrant closer investigation for root-zone stress or disease.

Relevant products for root-zone health and hygiene:

• Flairform Pythoff — hydroponic nutrient-solution treatment for root-zone hygiene, algae/slime control and system cleanliness as directed
• GT Oxy Plus — hydrogen peroxide for nutrient-solution oxygenation, root-zone hygiene and system sanitisation as directed
• H&G Drip Clean — drip-line maintenance
• Beneficial Microorganisms — supporting root-zone biology

Pesticides and Beneficial Insects

Warning: Pesticides and Beneficial Organisms

This is one of the most important considerations in any IPM program that combines chemical and biological controls. Failing to account for pesticide residues before releasing beneficial organisms is one of the most common — and costly — mistakes in biological pest management.

• Contact pesticides can kill beneficial organisms directly. Predatory mites, parasitic wasps, and other beneficials are vulnerable to many of the same products used to control pest insects and mites.
• Residues may remain after spraying. Residual activity varies substantially by active ingredient, formulation and application method. Organic and botanical products can also leave residues that affect biological controls.
• Oils and soaps may affect beneficial organisms. Neem oil, insecticidal soaps, and essential oil-based sprays can harm or impair predatory mites and insects if residues are present at the time of release, even if the products are considered low-risk.
• Natural products are not automatically compatible with beneficials. "Organic" or "natural" does not mean safe for beneficial organisms. Always treat natural products with the same caution as synthetic ones when planning a biological control program.
• Compatibility must be checked before releasing predatory mites or insects. Contact your beneficial supplier and the product manufacturer to confirm the re-introduction interval for any product used before releasing beneficials into the growing space.

Live-beneficial availability changes quickly. Check current Green Genius availability or speak with your beneficial supplier, and always discuss your recent spray history before placing an order.

Preventative IPM Routine

A consistent, structured routine is the foundation of effective IPM. The goal is to catch problems early, maintain conditions that are unfavourable to pests, and keep the growing environment clean — not to apply pesticides on a schedule.

Routine Inspection (During the Growing Cycle)

Carry out the following at least once or twice per week:

• Check new growth and growing tips for distortion, discolouration, or pest activity
• Inspect leaf undersides on a representative sample of plants — this is where many pests feed and lay eggs
• Look for webbing on leaves, stems, and between growing tips
• Check growing media surfaces for larvae, unusual activity, or algae growth
• Watch for flying insects around pots, growing media, and lights
• Inspect and count sticky traps — record the numbers and pest types captured
• Inspect any new plants or cuttings that have entered the space since the last inspection

Between Growing Cycles

Use the period between cycles to reset the environment and reduce carry-over pest pressure:

• Remove all plant debris, spent media, and dead material from the growing space
• Clean trays, saucers, and pots thoroughly before reuse
• Clean floors, walls, and drainage areas
• Inspect and flush irrigation lines and reservoirs
• Replace all monitoring traps with fresh ones before the next cycle begins
• Check air-intake filters and clean or replace as needed
• Review any recurring pest problems from the previous cycle and adjust your prevention strategy accordingly
• Clean and disinfect all reusable equipment — tools, propagation trays, net pots, and stakes

IPM for Living Soil

Living soil systems support a complex web of organisms — bacteria, fungi, protozoa, nematodes, predatory mites, rove beetles, springtails, and many others. Not every organism you observe in living soil is a pest. Many are beneficial, and some are essential to the function of the system.

Before treating any organism found in living soil, confirm that it is actually causing harm. Predatory mites, rove beetles, and springtails are commonly found in healthy living soil and actively suppress pest populations. Treating them as pests undermines the biological balance that makes living soil effective.

Key Principles for Living Soil IPM

• Predatory mites and rove beetles are generally beneficial allies. Confirm identification before treating them as pests.
• Soil biology is disrupted by broad-spectrum treatments. Avoid applying products that kill indiscriminately into living soil systems unless the situation genuinely requires it.
• Mulch helps maintain moisture, moderate temperature, and support surface-dwelling beneficial organisms. It also reduces algae growth on the media surface.
• Moisture management remains important even in living soil. Persistently wet conditions favour fungus gnats and can suppress beneficial soil organisms.
• Neem and Karanja amendments are commonly used in living soil IPM as soil conditioners and pest deterrents. HPO Karanja Meal is well suited to indoor living soil use due to its low odour profile.
• Avoid unnecessary broad-spectrum treatments. If a specific pest is confirmed, select the most targeted option available rather than a broad-spectrum spray that may disrupt the soil food web.

IPM for Hydroponics

Hydroponic systems present specific IPM challenges. The absence of soil removes some pest habitats but introduces others — particularly those associated with standing water, algae, and reservoir hygiene. Root health is also more directly visible and more immediately critical in hydroponic systems than in soil.

Key Hydroponic IPM Considerations

• Reservoir hygiene: Keep reservoirs clean and covered. Algae and organic build-up can support pest and pathogen pressure. Flairform Pythoff is used in nutrient solution as directed for root-zone hygiene and algae/slime control, while GT Oxy Plus can be used at product-specific rates for nutrient-solution oxygenation, root-zone hygiene and system sanitisation.
• Tray hygiene: Clean growing trays regularly to remove algae, salt deposits, and organic debris. Standing water and persistent surface moisture can strongly favour fungus gnat populations in hydroponic environments.
• Algae control: Algae on exposed surfaces provides food and habitat for fungus gnats and shore flies. Block light from reaching nutrient solution and growing media surfaces where possible.
• Root health: Inspect roots regularly where the system allows. Healthy hydroponic roots are often white to cream and firm, although nutrient and organic inputs can stain roots. Soft, slimy, deteriorating or foul-smelling roots warrant closer investigation before assuming a foliar pest cause.
• Irrigation cleanliness: Flush and clean drip lines, emitters, and reservoirs between cycles. H&G Drip Clean prevents salt and sediment buildup in irrigation systems.
• Propagation hygiene: Start cuttings and seedlings in clean propagation media and trays. Inspect all propagation material before it enters the main system.
• Wet growing media: Avoid overwatering in coco and other hydroponic substrates. Persistently wet media in the upper zone supports fungus gnat larvae even in hydroponic systems.
• Environmental control: Maintain appropriate temperature, humidity, and airflow. Stagnant, humid conditions favour many common pests.

IPM for Indoor Grow Tents

Indoor grow tents create a contained environment that can be both an advantage and a vulnerability from an IPM perspective. The enclosed space concentrates pest populations and makes spread between plants rapid — but it also makes monitoring, environmental control, and quarantine more manageable.

• Inspect incoming plants: Never introduce a new plant, cutting, or propagation material into a tent without inspecting it thoroughly first. Quarantine new material in a separate space for an appropriate observation period before introduction.
• Sticky-trap monitoring: Use yellow or blue sticky traps where they match the pests you are monitoring and inspect them on a consistent schedule. Record counts. A sudden increase in trap captures is an early warning sign.
• Airflow: Maintain good air circulation through and across the canopy. Stagnant zones inside tents create ideal conditions for spider mites and fungal issues. Ensure your extraction and circulation fans are appropriately sized for the tent volume.
• Environmental management: Monitor temperature and humidity inside the tent, not just in the room. Conditions inside a tent can differ significantly from the surrounding environment. Use an environmental controller or monitor to maintain appropriate parameters.
• Remove dead material: Remove dead leaves, spent flowers, and debris from inside the tent promptly. Do not allow organic matter to accumulate on the tent floor or in trays.
• Maintain access: Keep plants spaced and trained so you can inspect all parts of the canopy. Dense, inaccessible canopies allow pest populations to build undetected.
• Prevent movement between tents: If you run multiple tents, treat each as a separate zone. Do not move plants, tools, or equipment between tents without cleaning first — particularly if one tent has a known pest problem.
• Clean between cycles: Empty the tent completely between cycles. Wipe down all interior surfaces, clean the floor, and replace monitoring traps before the next cycle begins.
• Quarantine affected plants: If a pest is identified in one plant, isolate it from the rest of the tent immediately while you assess the extent of the infestation.

When to Escalate Treatment

Not every pest sighting requires immediate chemical intervention. Matching your response to the level of pest pressure is a core principle of IPM — it reduces unnecessary chemical use, protects beneficial organisms, and avoids creating resistance.

Low Pest Pressure

A small number of pests detected on monitoring traps or during inspection, with no visible plant damage:

• Continue regular monitoring and increase inspection frequency
• Correct any environmental conditions that favour the pest (humidity, temperature, moisture, airflow)
• Remove any affected plant material physically
• Consider introducing biological controls if the environment is suitable and no incompatible residues are present

Moderate Infestation

Visible pest activity on multiple plants, some plant damage, rising trap counts:

• Remove and dispose of heavily affected leaves and plant material
• Increase monitoring frequency based on pest pressure and the treatment or biological-control plan
• Assess biological control options — if no incompatible pesticide residues are present, this may be an appropriate time to introduce beneficials
• If biological control is not appropriate or available, select a targeted treatment based on the confirmed pest and apply according to the product label
• Reassess according to the pest biology, treatment label and biological-control guidance rather than using a universal interval

Heavy Infestation

Widespread pest activity, significant plant damage, high trap counts across multiple areas:

• Isolate affected plants from the rest of the growing space where practical
• Remove heavily affected plant material — prioritise reducing the pest population before treating
• Select an appropriately labelled treatment for the confirmed pest and apply thoroughly, following the product label
• Clean the growing environment — remove debris, clean trays, and address any environmental conditions contributing to the infestation
• Do not release beneficial organisms until pesticide residues have cleared and the environment has been reassessed
• Reassess the situation before planning the next step
