How to spray cucumbers with folk methods for spider mite control in a greenhouse?

Understanding the Spider Mite Threat to Cucumbers in a Greenhouse

Identifying Spider Mites

Signs and Symptoms of Infestation

Spider mites on greenhouse cucumbers reveal themselves through distinct visual cues and plant responses. Early detection prevents rapid population growth and reduces the need for chemical intervention.

Fine, web‑like threads on leaf undersides, especially near the main veins.
Tiny, moving specks that appear as pale, yellow‑green dots; they increase in number as the infestation progresses.
Stippling or speckled discoloration on foliage, often forming a mosaic pattern that spreads outward from the leaf edge.
Leaf curling or cupping, with affected leaves turning upward or downward, reducing photosynthetic area.
Premature leaf drop, leaving gaps in the canopy that expose remaining leaves to excess light and temperature fluctuations.
Stunted growth and reduced fruit size, resulting from impaired nutrient transport and photosynthesis.
Presence of a faint, dusty residue on leaves, composed of shed mite exoskeletons.

These symptoms indicate an active spider mite population and signal the need for immediate application of traditional cucumber sprays, such as aqueous extracts of neem, garlic, or pepper, to interrupt the mite life cycle and protect the crop. Prompt action based on these signs maintains plant vigor and fruit quality without resorting to synthetic pesticides.

Factors Contributing to Spider Mite Proliferation

Spider mites thrive when environmental conditions favor rapid reproduction and limited natural regulation. High temperatures, especially above 30 °C, accelerate egg development and increase population growth rates. Low relative humidity, typically below 50 %, reduces mite mortality and prolongs adult longevity. In a greenhouse, inadequate ventilation creates microclimates with these temperature‑humidity combinations, promoting infestations.

Dense cucumber plantings provide abundant food and shelter, allowing mites to migrate easily between leaves. Overcrowding also limits airflow, further lowering leaf surface moisture. Excessive use of broad‑spectrum insecticides eliminates predatory insects such as Phytoseiulus spp., removing a primary biological control mechanism. Repeated applications of the same chemical class foster resistance, rendering treatments less effective and encouraging mite population rebounds.

Dusty or polluted air deposits fine particles on leaf surfaces, impairing the mites’ ability to disperse naturally and encouraging them to remain and reproduce on the host. Nutrient imbalances, particularly excess nitrogen, produce tender foliage that is more attractive to mites and supports higher fecundity. Finally, irregular watering schedules cause fluctuations in leaf turgor, creating stress conditions that weaken plant defenses and make cucumbers more susceptible to mite colonization.

Preparing for Folk Method Application

Safety Precautions

Applying traditional cucumber sprays to manage spider mites in a greenhouse requires strict safety measures. Operators must protect themselves, the crop, and the environment throughout preparation, application, and post‑treatment phases.

Wear chemical‑resistant gloves, goggles, and a mask rated for fine particles; folk extracts can contain irritants such as neem oil, garlic, or hot pepper compounds.
Ensure proper ventilation; open vents and use fans to disperse airborne droplets and prevent buildup of volatile compounds.
Prepare solutions in a dedicated area away from food preparation zones; label containers with contents, concentration, and preparation date.
Test a small leaf area before full coverage; observe for phytotoxic reactions for at least 24 hours.
Calibrate sprayers to deliver a uniform droplet size; avoid excessive runoff that can soil the growing medium and affect root health.
Store remaining mixture in sealed, child‑proof containers; discard any solution older than 48 hours to prevent microbial growth.
Clean equipment thoroughly after each use; rinse with water and a mild detergent, then dry to prevent cross‑contamination.
Document application details—date, time, concentration, and personnel—so that future treatments can be evaluated for efficacy and safety compliance.

Following these precautions minimizes health risks for workers, preserves cucumber quality, and reduces unintended environmental impact.

Essential Tools and Materials

Essential tools for preparing and applying traditional cucumber sprays in a greenhouse include a clean, food‑grade container for mixing, a hand‑held sprayer with adjustable nozzle, and a calibrated measuring cup or graduated cylinder. The sprayer should have a fine mist setting to ensure even coverage on foliage and be easy to disassemble for thorough cleaning after each use.

Key materials for the folk formulation consist of:

Diluted neem oil (5 % active ingredient) or a cold‑pressed vegetable oil base.
A mild soap such as potassium‑based horticultural soap to act as an emulsifier.
Freshly harvested garlic cloves, crushed and steeped for 24 hours.
Ground cayenne pepper or hot pepper extract for repellent properties.
Distilled water to avoid mineral buildup in the spray system.
Optional: a few drops of rosemary or peppermint essential oil to enhance deterrent effect.

Preparation steps:

Combine 1 L of distilled water with 1 tsp of horticultural soap; stir until fully dissolved.
Add 1 tsp of neem oil; mix gently to create a stable emulsion.
Incorporate 2 tbsp of strained garlic infusion and ½ tsp of cayenne powder; stir thoroughly.
If desired, blend in 5 drops of essential oil; mix again.
Transfer the solution to the sprayer, adjust the nozzle to a fine mist, and test on a single leaf before full application.

Safety considerations require wearing gloves and eye protection during mixing, labeling the container with preparation date, and storing the remaining solution in a cool, dark place for no longer than seven days. Clean the sprayer after each session to prevent clogging and cross‑contamination.

Effective Folk Spraying Methods for Spider Mites

Garlic-Based Sprays

Preparation of Garlic Infusion

Garlic infusion serves as a conventional spray to suppress spider mite populations on cucumber crops grown under greenhouse conditions. The preparation relies on readily available ingredients and simple equipment, making it suitable for small‑scale horticultural operations.

Materials required: fresh garlic cloves (approximately 150 g per litre of water), non‑chlorinated water, a stainless‑steel or enamel pot, a fine mesh strainer, a clean container for storage, and a measuring cup. Optional additives include a few drops of horticultural oil to improve leaf coverage.

Preparation steps:

Peel and crush the garlic cloves to release the volatile compounds.
Combine the crushed garlic with the measured water in the pot.
Bring the mixture to a gentle boil; maintain the temperature for 10 minutes without vigorous bubbling.
Remove the pot from heat and allow the solution to cool to ambient temperature.
Strain the liquid through the mesh to eliminate solid particles.
Transfer the clear infusion into the storage container; label with the preparation date.

Application guidelines:

Dilute the concentrate with water at a ratio of 1 part infusion to 4 parts water (e.g., 250 ml infusion + 1 L water).
Add 1 % horticultural oil if leaf adhesion is required.
Apply the spray in the early morning or late afternoon, covering both upper and lower leaf surfaces.
Repeat the treatment every 5–7 days or after heavy rainfall.

Storage and safety:

Keep the concentrate in a cool, dark place; use within two weeks.
Avoid contact with eyes; wear protective gloves during handling.
Discard any solution that develops foul odor or visible mold.

Application Technique

The application technique for folk‑based cucumber sprays targeting spider mites in a greenhouse relies on precise preparation, thorough coverage, and disciplined timing.

Prepare the spray by combining finely ground neem seed cake, a handful of dried chrysanthemum flowers, and a liter of warm water. Add one teaspoon of liquid soap as an emulsifier, stir until the mixture becomes uniformly milky, and let it steep for 30 minutes. Strain through a fine mesh to remove solid particles, then fill a hand‑held sprayer with the clarified liquid.

Before use, calibrate the sprayer to deliver 2 ml per square meter. Adjust the nozzle to produce a fine mist that reaches the underside of leaves without causing runoff. Test the spray on a single leaf; if droplets coalesce, increase the dilution ratio by 10 % and retest.

Apply the solution in the early morning or late afternoon when ambient temperature stays below 25 °C and humidity exceeds 70 %. Cover the entire canopy, focusing on leaf margins and the undersides where spider mites congregate. Repeat the treatment every five days for three cycles, then shift to a bi‑weekly schedule if mite counts remain low.

After each application, inspect plants for leaf damage and record mite presence. Flush the sprayer with clean water, store it in a dry place, and replenish the solution only with freshly prepared batches to preserve efficacy.

Onion Peel Solution

Creating Onion Peel Concentrate

Onion skins contain compounds that repel spider mites and can be turned into a liquid concentrate suitable for cucumber foliage in protected cultivation.

To prepare the concentrate, follow these precise steps:

Collect clean, dry outer layers from 2–3 medium onions; discard any spoiled material.
Cut the skins into 1‑cm strips to increase surface area.
Place the strips in a glass jar and add cold distilled water at a ratio of 1 L per 100 g of skins.
Seal the jar and let it steep for 24 hours in a cool, dark place, shaking gently every 6 hours.
After steeping, filter the mixture through a fine mesh or cheesecloth, retaining the liquid.
Transfer the filtrate to a clean amber bottle; label with preparation date.

Application guidelines:

Dilute the concentrate 1 part concentrate to 9 parts water (10 % v/v) before spraying.
Add a few drops of mild liquid soap as a surfactant to improve leaf coverage.
Apply in the early morning or late afternoon when leaf temperature is below 25 °C.
Spray until runoff on cucumber leaves and stems, ensuring both upper and lower surfaces are wet.
Repeat every 5–7 days, or after heavy rain, until mite populations decline.

Safety and storage:

Use gloves and eye protection during preparation to avoid irritation from onion residues.
Store the concentrate in a refrigerator at 4 °C; it remains effective for up to 2 weeks.
Discard any batch that develops foul odor or visible mold.

The described method leverages readily available kitchen waste, avoids synthetic chemicals, and aligns with organic pest‑management principles for greenhouse cucumber production.

Best Practices for Spraying

Effective control of spider mites on cucumber crops in greenhouse environments requires precise application of folk‑derived sprays. Success depends on preparation, timing, equipment, and environmental management.

Use an aqueous extract of neem seed cake, garlic, or hot pepper at a concentration of 2–3 % v/v. Dilute with water to achieve a fine mist that covers leaf surfaces without runoff.
Filter the mixture through a fine mesh to remove solids that could clog spray nozzles.
Apply during the early morning or late afternoon when temperatures are 18–24 °C and relative humidity exceeds 70 %. These conditions promote leaf retention and reduce rapid evaporation.
Adjust spray pressure to produce droplets sized 100–200 µm; this range maximizes contact with spider mite colonies while minimizing drift.
Treat only the underside of leaves, where mites congregate, ensuring thorough coverage of veins and crevices.
Repeat applications every 5–7 days until populations drop below economic thresholds, monitoring with a hand lens or sticky traps.
Rotate folk sprays with at least one botanical agent containing a different active compound to prevent resistance development.
Maintain greenhouse ventilation to keep humidity below 80 % after treatment, limiting fungal growth that may result from excessive moisture.
Record spray dates, concentrations, and observed mite counts in a logbook to evaluate efficacy and adjust protocols as needed.

Tobacco Infusion

Crafting the Tobacco Spray

Tobacco spray is a traditional remedy for spider mite infestations on cucumber vines cultivated in greenhouse environments. The preparation relies on readily available materials and yields a solution that deters mite feeding without harming the plant.

Ingredients and preparation

One cup of strong black tea or water‑steeped tobacco leaves (approximately 20 g).
Two teaspoons of liquid soap (non‑synthetic, biodegradable) to act as an emulsifier.
One liter of clean water, preferably filtered or boiled and cooled.

Procedure:

Submerge the tobacco leaves in the hot water; steep for 10 minutes, then strain to obtain a clear infusion.
Allow the infusion to cool to room temperature.
Add the liquid soap and stir until fully dispersed.
Dilute the mixture with additional water to reach a total volume of one liter if the initial infusion exceeds this amount.

Application guidelines

Apply the spray in the early morning or late afternoon to reduce leaf burn risk.
Cover the entire foliage, ensuring both upper and lower surfaces receive a thin, uniform coating.
Use a fine‑mist sprayer to achieve thorough coverage without runoff.
Repeat treatment every 5–7 days during peak mite activity, or after heavy rain that may wash off residues.
Observe plants for any signs of phytotoxicity; discontinue use if leaf discoloration occurs.

The described method provides a cost‑effective, low‑toxicity option for managing spider mites on cucumber crops within controlled greenhouse settings.

Cautions and Usage Guidelines

When employing traditional cucumber sprays to manage spider mites in greenhouse production, follow these safety and application parameters.

Prepare the solution with fresh botanical ingredients, clean water, and a mild surfactant. Filter the mixture before use to remove plant debris that could clog sprayers.

Cautions

Do not apply during the hottest part of the day; temperatures above 30 °C increase leaf burn risk.
Avoid contact with beneficial insects; spray only when pollinators are absent or after they have been removed from the area.
Do not exceed the recommended concentration; overly strong mixtures can cause phytotoxicity, manifested as leaf yellowing or necrosis.
Keep the formulation away from open flames and heat sources, as some essential oils are flammable.
Store any leftover solution in a sealed, labeled container, out of reach of children and pets, and discard after 48 hours.

Usage Guidelines

Test the spray on a single plant for 24 hours before full‑scale application; observe for adverse reactions.
Apply a fine mist to the underside of leaves, where spider mites reside, ensuring even coverage without runoff.
Repeat applications at 5‑ to 7‑day intervals until mite populations decline, then shift to a maintenance schedule of every 2‑3 weeks.
Rotate the spray with at least one alternative control method (e.g., biological agents) to prevent resistance development.
Record each application date, concentration, and observed effects for future reference and compliance with integrated pest management protocols.

Soap Solutions

Types of Soap for Pest Control

Effective spider‑mite management on greenhouse cucumbers often relies on soap‑based sprays derived from traditional practices. Selecting the appropriate soap determines contact toxicity, plant safety, and ease of preparation.

Insecticidal soap (potassium salts of fatty acids) – commercial formulations contain 1–3 % potassium salts, provide rapid knock‑down of mites, and degrade within 24 hours. Recommended dilution: 5 ml per litre of water for cucumber foliage.
Liquid castile soap – vegetable‑oil based, unscented, 10–15 % soap concentration. Dilute 2 ml per litre; add a drop of horticultural oil to improve spread. Suitable for organic operations, but may cause phytotoxicity on young leaves if applied under high light.
Pure dish‑washing liquid (non‑ionic, low‑phosphate) – inexpensive, 3–5 % concentration after dilution (10 ml per litre). Works as a surfactant to enhance coverage but lacks the fatty‑acid component needed for mite toxicity; best used as an adjuvant with other soaps.
Homemade soap mixture – combine grated natural soap (e.g., Marseille) with warm water, stir until dissolved, filter, then dilute to 2 % active soap. Provides a cost‑effective alternative, though consistency varies between batches.

Key preparation steps apply to all types:

Heat water to 40–45 °C, dissolve soap completely, then cool to ambient temperature before mixing with cucumber foliage.
Add a small amount of horticultural oil (0.5 %) to improve leaf coverage and reduce runoff.
Apply in the early morning or late evening to avoid leaf burn; repeat every 5–7 days until mite populations decline.

Monitoring after each application is essential. If leaf discoloration appears, reduce soap concentration by half and increase the interval between sprays. Consistent use of the appropriate soap type, combined with proper dilution and timing, offers reliable control of spider mites on cucumber plants cultivated in greenhouse environments.

Mixing and Applying Soap Spray

Mix a liquid soap solution by dissolving 1–2 % (by volume) of pure castile or potassium soap in warm water. Use distilled or filtered water to prevent mineral buildup in spray equipment. Stir until the soap is completely emulsified; a small amount of vegetable oil (≈0.5 %) can be added to improve leaf coverage, but avoid excessive oil that may clog stomata.

Measure the mixture with a calibrated container, then transfer it to a clean, fine‑mist greenhouse sprayer. Fill the sprayer no higher than three‑quarters full to maintain consistent pressure and prevent overflow. Before each use, shake the bottle vigorously to keep the emulsion uniform.

Apply the spray early in the morning or late in the afternoon when cucumber foliage is dry and ambient temperature is below 25 °C. Cover the entire plant, emphasizing the undersides of leaves where spider mites reside. Ensure droplets are fine enough to coat surfaces without runoff; a spray interval of 5–7 seconds per pass typically achieves this density.

Repeat applications every 5–7 days, or sooner if mite populations increase. After each treatment, inspect leaves for residual soap; excess buildup may cause phytotoxicity, especially on young tissue. Rinse plants with plain water after three consecutive sprays to prevent soap accumulation.

Maintain sprayer hygiene by flushing with a mild detergent solution after each season, then rinsing thoroughly with clean water. Store the soap mixture in a cool, dark place; prolonged exposure to heat can degrade active ingredients and reduce efficacy.

Herbal Infusions

Horsetail Decoction

Horsetail (Equisetum arvense) decoction provides a silica‑rich spray that suppresses spider mite populations on cucumber vines cultivated in greenhouse environments. The extract contains flavonoids and alkaloids that interfere with mite feeding and reproduction while remaining safe for the plant when applied correctly.

Application

Apply the diluted decoction using a fine‑mist sprayer, covering foliage until runoff.
Spray early in the morning or late afternoon to minimize leaf burn.
Repeat every 5–7 days during peak mite activity; increase frequency to every 3 days if infestations rise rapidly.
Include the undersides of leaves, where mites commonly reside.

Safety and Compatibility

Use a concentration of no more than 1 % (approximately 50 mL of decoction per 5 L of water) to avoid phytotoxic effects.
Conduct a spot test on a few leaves 24 hours before full‑scale application.
The solution is compatible with most organic fertilizers; avoid mixing with copper‑based fungicides, which may precipitate.

Integration with Cultural Practices

Maintain optimal greenhouse temperature (22–26 °C) and humidity (60–70 %) to discourage mite proliferation.
Remove heavily infested leaves promptly to reduce breeding sites.
Combine the horsetail spray with regular monitoring using sticky traps to assess population trends and adjust treatment intervals accordingly.

Dandelion Extract

Dandelion (Taraxacum officinale) yields a watery extract rich in flavonoids and sesquiterpene lactones that suppress spider‑mite activity on cucumber foliage grown under protected conditions. The preparation requires only mature leaves, clean water, and a fine mesh strainer.

Preparation

Harvest 200 g of fresh dandelion leaves, rinse thoroughly.
Chop leaves and steep in 2 L of lukewarm water (30–35 °C) for 30 minutes, stirring occasionally.
Filter the mixture through cheesecloth or a fine sieve; discard solids.
Dilute the filtrate with an equal volume of water to obtain a 1 % solution ready for spraying.

Application

Load the 1 % solution into a hand‑held or backpack sprayer calibrated for fine mist.
Apply to cucumber leaves until runoff, covering both upper and lower surfaces.
Conduct treatments early in the morning or late afternoon to reduce leaf burn.
Repeat every 5–7 days, or after heavy rain, until mite populations decline.

Safety and storage

Wear gloves and eye protection during preparation and spraying.
Store the concentrated extract in a sealed, opaque container at 4 °C; use within 7 days.
Rinse equipment with clean water after each use to prevent residue buildup.

The described protocol integrates a traditional botanical remedy into greenhouse cucumber production, offering a low‑cost, biodegradable alternative to synthetic acaricides.

Post-Treatment Care and Prevention

Monitoring After Spraying

Effective monitoring after applying traditional cucumber sprays for spider‑mite management in a greenhouse determines treatment success and guides subsequent actions.

Observe the following indicators:

Mite population density on leaf undersides (count per leaf segment).
Presence of new leaf damage or chlorosis.
Residual film on foliage (visual sheen, stickiness).
Temperature, relative humidity, and ventilation rates, because they influence mite activity and spray persistence.

Conduct inspections at regular intervals:

24 hours post‑application – verify spray coverage and immediate phytotoxic reactions.
72 hours – assess initial mite mortality and any resurgence.
7 days – evaluate longer‑term control and plant vigor.
Weekly thereafter until population remains below economic threshold.

Record data in a simple table: date, observer, mite count, damage rating, environmental readings, and any corrective measures. Consistent documentation enables trend analysis and rapid identification of treatment failure.

Re‑application criteria:

Mite count exceeds established threshold for two consecutive checks.
Visible leaf damage increases despite adequate coverage.
Environmental conditions shift toward high humidity and temperature, favoring mite reproduction.

When criteria are met, adjust spray concentration or combine folk spray with compatible biological agents, then resume the monitoring cycle.

Continual, systematic observation ensures that folk‑based sprays achieve reliable spider‑mite suppression while maintaining cucumber health in greenhouse production.

Greenhouse Environment Management

Humidity Control

Maintaining appropriate humidity is essential when applying traditional cucumber sprays to suppress spider mites in greenhouse cultivation. Relative humidity between 60 % and 70 % slows mite reproduction and improves the spread of aqueous folk preparations such as neem‑oil, garlic infusion, or insecticidal soap. Excessive dryness accelerates mite colonization and causes rapid evaporation of spray droplets, reducing contact time on foliage.

Effective humidity management combines measurement, adjustment, and coordination with spray schedules:

Install calibrated hygrometers at canopy level; record readings at two‑hour intervals.
Use humidifiers or misting systems to raise humidity when values fall below 60 %; prefer fine‑mist emitters that also deliver a thin layer of spray solution.
Increase ventilation during periods of high humidity (>75 %) to prevent fungal growth and leaf wetness that could compromise plant health.
Align spray application with peak humidity periods (early morning or late afternoon) to maximize droplet adherence and mite exposure.
Monitor leaf surface moisture with a wetness sensor; cease spraying if leaf wetness exceeds 2 mm to avoid phytotoxicity.

Consistent humidity control, coupled with regular folk spray applications, creates an environment unfavorable to spider mites while supporting cucumber vigor.

Air Circulation

Effective air circulation is essential when applying traditional cucumber sprays to combat spider mites in a greenhouse. Proper airflow distributes the solution evenly across foliage, reduces localized moisture buildup, and limits mite refuges.

To achieve optimal circulation during treatment, follow these steps:

Position oscillating fans at a height of 1.5–2 m, directing airflow parallel to the plant rows.
Set fan speed to a medium level; excessive velocity can dislodge spray droplets, while insufficient speed creates stagnant zones.
Operate fans for 10–15 minutes before spraying to clear residual humidity and for an additional 20–30 minutes after application to promote drying.
Rotate fan placement every two weeks to prevent the formation of micro‑climates within the greenhouse structure.

Maintain a minimum air exchange rate of 20 cubic meters per hour per square meter of canopy. Monitor relative humidity, keeping it between 50 % and 70 % during and after spraying; this range discourages mite reproduction while preserving plant health.

Regular assessment of airflow patterns using a handheld anemometer ensures consistent performance. Adjust fan placement or speed promptly if measurements fall below the recommended threshold.

Companion Planting Strategies

Companion planting can reinforce traditional cucumber spray routines aimed at spider‑mite suppression in greenhouse production. Selecting species that repel mites or attract their natural enemies reduces the frequency and concentration of foliar applications while maintaining crop vigor.

Marigold (Tagetes spp.) – emits volatile compounds that deter spider mites and other arthropods.
Nasturtium (Tropaeolum majus) – acts as a trap plant, drawing mites away from cucumbers.
Basil (Ocimum basilicum) – releases essential oils that inhibit mite reproduction.
Dill (Anethum graveolens) – attracts predatory insects such as lady beetles and predatory mites.

Intercropping these plants alongside cucumber rows creates a heterogeneous canopy that disrupts mite colonization patterns. The mixed foliage improves airflow, lowers leaf humidity, and enhances the penetration of aqueous folk sprays, resulting in more uniform coverage and reduced runoff.

To implement the strategy, arrange companion rows at a 30‑cm interval from cucumber beds, staggering planting dates so that companion foliage reaches full size before the first spray cycle. Apply the traditional cucumber spray early in the morning, using a fine mist to coat both cucumbers and neighboring companions. Monitor mite populations weekly; if trap plants show heavy infestation, replace them with fresh seedlings to maintain a sink for the pests.

Integrating these companion species into the greenhouse layout supports the efficacy of folk spray methods, lowers chemical load, and promotes a balanced ecosystem that naturally limits spider‑mite outbreaks.

Regular Inspection and Early Intervention

Regular inspection of cucumber crops is the first line of defense against spider mites in a greenhouse. Inspect leaf undersides weekly, focusing on the youngest foliage where mite populations establish quickly. Use a 10× hand lens or magnifying glass to detect the characteristic tiny, moving specks and the fine webbing they leave behind.

Early intervention follows detection. When mite numbers exceed five individuals per leaf, apply a folk spray immediately to prevent exponential growth. Effective homemade preparations include:

Soap‑water solution: dissolve 2 tablespoons of pure liquid soap in 1 liter of lukewarm water; spray until foliage is uniformly wet.
Garlic‑oil emulsion: blend 4 cloves of garlic with 200 ml of water, strain, add 1 teaspoon of vegetable oil, then dilute to 1 liter; apply to both leaf surfaces.
Neem‑seed extract: steep 50 g of crushed neem seeds in 1 liter of water for 24 hours, filter, and spray directly.

Apply the chosen spray in the early morning or late afternoon to reduce leaf burn and ensure mite contact. Repeat the application every 5–7 days until no mites are observed for two consecutive inspections.

Document each inspection: record date, cultivar, temperature, humidity, and mite count. This log facilitates trend analysis, allowing growers to adjust spray frequency and concentration before infestations reach damaging levels.
