Understanding Fitover (Fitoverm)
What is Fitover (Fitoverm)?
Active Ingredient and Mode of Action
Fitover (also marketed as Fitoverm) contains the avermectin derivative abamectin as its sole active ingredient. Abamectin belongs to the macrocyclic lactone class and is classified by the Insecticide Resistance Action Committee (IRAC) in Group 6, indicating a unique target site among miticides.
The compound exerts its effect by binding selectively to glutamate‑gated chloride channels in the nervous system of spider mites. This binding increases the permeability of the neuronal membrane to chloride ions, leading to hyperpolarization, paralysis, and eventual death of the mite. The action is both contact and ingestion based; mites that feed on treated leaf tissue absorb the toxin, while those that crawl on the surface are immobilized by direct contact. Systemic translocation within cucumber foliage is limited, so efficacy depends on thorough coverage of leaf undersides where spider mites reside.
Key characteristics of the mode of action:
- High affinity for invertebrate glutamate‑gated chloride channels, negligible activity on mammalian receptors.
- Rapid onset of paralysis within minutes of exposure.
- Low residual activity; effectiveness declines as the compound degrades under UV light and high temperature.
- No cross‑resistance with miticides that target mitochondrial complex III or acetylcholinesterase.
Understanding the active ingredient and its neurotoxic mechanism enables precise timing of applications, optimal spray volume, and integration into resistance‑management programs for cucumber production in greenhouse environments.
Target Pests
Fitover (Fitoverm) is formulated to control the spider mite complex that infests cucumber crops grown under protected conditions. The primary target pest is the two‑spotted spider mite (Tetranychus urticae), which is the most common species responsible for rapid population explosions in greenhouses. Secondary targets include:
- Tetranychus cinnabarinus (carmine spider mite) – capable of reproducing on cucumber foliage under high humidity.
- Polyphagotarsonemus latus (broad mite) – often co‑occurs with spider mites and contributes to leaf stippling.
- Panonychus ulmi (European red mite) – less prevalent on cucumbers but can appear in mixed infestations.
All target stages—eggs, larvae, nymphs, and adult females—are susceptible to the active ingredient in Fitover. The product penetrates the mite’s cuticle, disrupting cellular respiration and leading to mortality within 24–48 hours. Effective control requires accurate dosage and thorough coverage of leaf undersides, where spider mites concentrate.
Safety and Precautions
Personal Protective Equipment (PPE)
When applying Fitover (Fitoverm) to cucumber crops for spider‑mite control in a greenhouse, workers must wear equipment that prevents skin contact, inhalation, and eye exposure to the pesticide.
Select the following items:
- Nitrile or neoprene gloves, chemical‑resistant, inspected for tears before each use.
- Full‑length coveralls made of impermeable fabric, with sealed seams and a front zipper.
- Safety goggles or a full face shield that meets ANSI Z87.1 standards.
- Respiratory protection rated for organic vapors, such as an N‑95 or P‑3 filter cartridge, fitted to a half‑mask or full‑face respirator.
- Waterproof boots with steel toe caps and chemical‑resistant overshoes.
Before each application, verify that all PPE is clean, intact, and properly sized. Don the equipment in the prescribed order: boots, coveralls, gloves, goggles, then respirator. After spraying, remove items from the outermost layer inward to avoid contaminating clothing, and dispose of or decontaminate them according to the manufacturer’s instructions. Store reusable PPE in a dry, ventilated area away from direct sunlight.
Maintain a log of PPE inspection dates, replacement intervals, and any incidents of breach. Regular training on correct donning, doffing, and decontamination procedures reinforces safety and ensures compliance with greenhouse pesticide regulations.
Environmental Considerations
Fitover (Fitoverm) is a systemic acaricide applied to cucumber foliage to suppress spider mite populations in greenhouse production. Its environmental profile demands careful management to minimize adverse effects.
Application timing should align with pest monitoring data to reduce unnecessary treatments. Spraying only when mite thresholds are reached limits chemical load in the air and on plant surfaces, decreasing exposure for beneficial insects such as predatory mites and lady beetles.
Formulation residues persist in irrigation water and runoff. Collecting and treating excess runoff prevents contamination of surrounding soil and water bodies. If drainage is unavoidable, incorporate activated carbon filters or biofiltration beds to capture residual compounds before discharge.
Ventilation rates influence vapor accumulation. Maintaining adequate air exchange lowers inhalation risk for workers and reduces volatilization losses that could affect neighboring ecosystems.
Resistance management requires rotating Fitover with products of different modes of action. Alternating chemicals prevents selection pressure that could render the acaricide ineffective and reduces the overall chemical burden in the greenhouse environment.
Disposal of empty containers and unused product must follow local hazardous waste regulations. Rinsing containers with a minimal amount of water, then collecting the rinse for proper waste treatment, prevents soil and water contamination.
Implementing these practices integrates Fitover use into an environmentally responsible pest management program while preserving crop health and greenhouse ecosystem stability.
Preparing for Treatment
Identifying Spider Mite Infestation
Symptoms on Cucumber Plants
Spider mite damage on cucumber vines appears as stippled or speckled discoloration on the upper leaf surface. The spots are tiny, pale yellow to bronze, and often coalesce into larger patches that cause the leaf to look mottled. As the infestation progresses, the affected tissue turns bronzed or brown, and the leaf may curl upward or downward, reducing photosynthetic capacity.
A second indicator is the presence of fine webbing. Web is most noticeable on the undersides of leaves, at leaf axils, and around the growing points. The web may be thin and translucent in early stages, becoming denser and more visible as populations increase.
A third symptom is the presence of the mites themselves. Adult spider mites are less than 0.5 mm long, red to yellowish, and move quickly when the leaf is disturbed. Eggs are often laid on the lower leaf surface and appear as tiny, white, oval bodies. Heavy infestations lead to premature leaf drop, stunted vines, and reduced fruit set, signaling the need for immediate intervention with a suitable acaricide such as Fitover.
Inspection Techniques
Effective inspection is the foundation of successful Fitover (Fitoverm) application for cucumber spider‑mite management in greenhouse production.
Begin each crop cycle with a baseline survey. Randomly select 10–15 plants per 100 m², examine the underside of the newest leaves, and record the number of live mites, eggs, and webbing per leaf. Use a 10× hand lens or a portable microscope to ensure accurate counts.
Maintain a weekly scouting schedule. Record observations in a log that includes date, location, temperature, relative humidity, and mite density. Compare current counts with the established economic threshold of 5–7 mites per leaf; exceedance triggers treatment.
Deploy sticky cards (yellow or blue) at canopy height. Replace cards every 5 days and count trapped mites. Integrate trap data with leaf inspections to confirm population trends.
Inspect plant edges and peripheral zones more frequently, as spider mites preferentially colonize stressed or low‑light areas. Remove heavily infested leaves before treatment to reduce canopy shelter.
Before each Fitover spray, verify that mite density meets or exceeds the threshold, that plants are at the appropriate growth stage (young vines with expanding leaves), and that environmental conditions (temperature 20–30 °C, relative humidity ≤70 %) favor product activity.
After application, conduct a post‑treatment check 48 hours later. Sample the same plants used in the pre‑treatment survey, count surviving mites, and assess web reduction. If mite numbers remain above 2 per leaf, schedule a second application according to label‑specified interval.
Document all inspection results, treatment dates, and product rates in a centralized database. Use the compiled data to refine scouting frequency, adjust threshold levels, and improve overall Fitover program efficacy.
Choosing the Right Concentration
Dosage Recommendations for Cucumbers
Fitover (also marketed as Fitoverm) is a systemic miticide containing the active ingredient abamectin, registered for spider‑mite control on cucumber crops grown in greenhouse conditions. The product must be mixed with water before application; it is not suitable for direct spraying.
- Recommended concentration for cucumber foliage: 0.12 ml of product per liter of water (equivalent to 12 g a.i. ha⁻¹).
- For early‑stage vines (first true leaves), reduce the rate to 0.08 ml L⁻¹ to avoid phytotoxicity.
- Apply a second dose 7–10 days after the initial treatment if mite populations remain above threshold levels.
- Maximum cumulative application per growing cycle: three sprays, not exceeding 0.36 ml L⁻¹ total.
Application must be performed with a fine‑mist sprayer delivering uniform coverage of both leaf surfaces. Ensure leaf wetness for at least 5 minutes to facilitate absorption. Do not exceed a spray volume of 200 L ha⁻¹ to prevent runoff. Observe a pre‑harvest interval of 7 days before marketable fruit is harvested.
To delay resistance development, alternate Fitover with miticides from different chemical groups (e.g., spiromesifen, bifenthrin) according to a rotating schedule. Record each application, including date, concentration, and observed mite counts, to adjust future treatments based on field efficacy.
Factors Influencing Concentration
When preparing a Fitover (Fitoverm) spray for cucumber crops afflicted by spider mites, the concentration of the active ingredient depends on several controllable variables.
- Water temperature: Higher temperatures increase solubility but also accelerate degradation; aim for 20–25 °C to maintain stability.
- Mixing order: Dissolve the concentrate in a small volume of water before adding the remainder; this prevents precipitation and ensures uniform distribution.
- Formulation type: Emulsifiable concentrates require vigorous agitation, whereas water‑soluble granules need thorough stirring to achieve the target concentration.
- Water quality: Hard water can precipitate salts, reducing bioavailability; use softened or deionized water when possible.
- Equipment calibration: Verify pump and nozzle flow rates before each application; a mis‑calibrated system can produce a solution that deviates by up to 15 % from the intended strength.
- Ambient humidity and leaf wetness: High humidity prolongs droplet residence time, allowing partial evaporation and concentration increase; adjust spray volume accordingly.
- Time elapsed after mixing: Active ingredients begin to break down within hours; apply the solution within the recommended window, typically no longer than 4 h from preparation.
By controlling these factors, growers can achieve the precise concentration needed for effective mite control while minimizing phytotoxic risk.
Gathering Necessary Equipment
Sprayer Types
When treating cucumber crops for spider mites with Fitover in a greenhouse, the choice of sprayer determines coverage uniformity, droplet size, and product efficiency.
Backpack sprayers equipped with a low‑volume nozzle produce droplets in the 100–150 µm range, suitable for leaf‑surface contact without runoff. Adjust pressure to 30–40 psi to maintain consistent atomization.
Hand‑held trigger sprayers offer rapid maneuverability for spot treatments. Use a fine‑mist nozzle (80–120 µm droplets) and limit application to affected vines to conserve product.
Powered pressure‑sprayers with a rotary atomizer generate a fine fog that penetrates dense foliage. Set pressure to 60–80 psi and select a fan‑type nozzle to achieve 50–80 µm droplets, maximizing spider mite mortality while minimizing phytotoxic risk.
Electrostatic sprayers charge droplets, enhancing adhesion to leaf surfaces. Pair with a medium‑volume nozzle (120–150 µm) and operate at 40 psi to ensure even distribution across the canopy.
When selecting a sprayer, consider:
- Compatibility with Fitover formulation – ensure material resistance to oil‑based components.
- Droplet size target – smaller droplets improve coverage but increase drift risk; adjust based on greenhouse ventilation.
- Pump capacity – match volume output to the area to be treated, avoiding excessive runoff.
- Ease of cleaning – choose equipment with detachable parts to prevent residue buildup that could affect subsequent applications.
Proper calibration, routine maintenance, and adherence to the manufacturer’s dosage recommendations will optimize spider mite control while preserving cucumber plant health.
Measuring Tools
Accurate dosing of Fitover (Fitoverm) is essential for effective spider‑mite control on greenhouse cucumbers. Use a calibrated sprayer to deliver the exact volume per hectare; verify calibration before each application. A digital flow meter attached to the pump records real‑time discharge, allowing immediate correction if flow deviates from the target rate.
Measure solution concentration with a portable refractometer or a colorimetric test kit. Record the reading and adjust the mixing ratio until the specified ppm is reached. Pressure gauges installed on the sprayer manifold ensure consistent atomisation; maintain pressure within the manufacturer’s recommended range to achieve uniform leaf coverage.
Monitor environmental conditions that influence pesticide performance. A combined temperature‑humidity probe provides data for deciding optimal spray windows, while a leaf wetness sensor confirms that foliage remains dry enough to prevent runoff. Log all measurements in a dedicated treatment sheet to track compliance and facilitate future adjustments.
Application of Fitover (Fitoverm)
Mixing the Solution
Water Quality Considerations
When preparing Fitover solutions for cucumber spider‑mite management in a greenhouse, water quality directly influences product stability, plant tolerance, and pest control efficacy. Use water that meets the following specifications:
- pH between 5.5 and 6.5; outside this range, the active ingredient degrades rapidly.
- Hardness below 150 mg L⁻¹ CaCO₃; high calcium and magnesium interfere with spray droplet formation and reduce leaf coverage.
- Free chlorine less than 0.5 mg L⁻¹; chlorine oxidizes the active component, diminishing toxicity to mites.
- Temperature between 10 °C and 25 °C; colder water slows dissolution, hotter water accelerates volatilization of the pesticide.
Measure these parameters with calibrated meters before each mixing session. If pH is high, adjust with phosphoric or citric acid; if hardness exceeds the limit, treat with a water softener or use reverse‑osmosis water. Chlorine can be removed by allowing water to stand for 24 hours or by adding a small amount of sodium thiosulfate. Maintain consistent temperature by storing water in insulated containers or heating it gently if needed.
Consistent water quality ensures uniform concentration of Fitover in the spray, prevents phytotoxic reactions on cucumber foliage, and maximizes mortality of spider mites. Regular monitoring and corrective actions are essential components of an effective greenhouse pest‑management program.
Proper Dilution Steps
Fitover (Fitoverm) is a systemic acaricide applied as a foliar spray. Correct dilution ensures efficacy and minimizes phytotoxic risk.
- Verify the product’s label for the recommended concentration against spider mites on cucumbers. Typical rates range from 0.5 mL to 1.0 mL per liter of water, depending on infestation severity and plant growth stage.
- Prepare a clean mixing container of adequate volume. Rinse thoroughly to remove residues that could alter the solution.
- Measure the required volume of Fitover with a calibrated syringe or graduated cylinder. Accuracy within ±5 % prevents under‑ or overdosing.
- Add the measured product to a small amount of water (approximately 100 mL) to create a stock solution. Stir gently until fully dispersed; avoid vigorous shaking that may generate foam.
- Transfer the stock solution into the main spray tank containing the total volume of water. Complete the tank with clean, lukewarm water; temperature should not exceed 30 °C to maintain chemical stability.
- Mix the tank contents by circulating the pump for 2–3 minutes. Verify uniform distribution by inspecting a sample for clarity and absence of droplets.
- Conduct a leaf‑burn test on a single cucumber leaf before full‑scale application. Apply the spray to the test leaf, wait 24 hours, and observe for discoloration. If symptoms appear, reduce the concentration by 10 % and repeat the test.
- Apply the solution using a calibrated sprayer, ensuring thorough coverage of leaf undersides where spider mites reside. Maintain a spray pressure of 200–250 kPa to achieve fine droplets.
- Record the batch number, dilution ratio, application date, and weather conditions. This documentation supports traceability and future adjustments.
Following these steps produces a consistent, effective Fitover treatment for cucumber spider mite control in greenhouse environments.
Application Technique
Coverage Guidelines
Fitover (Fitoverm) must be applied to cucumber foliage in a greenhouse with complete leaf wetness to achieve effective spider‑mite control. Coverage guidelines focus on spray volume, droplet size, and uniform distribution across all plant surfaces.
The recommended spray volume is 300–400 L ha⁻¹ (approximately 3–4 mL L⁻¹ of water) when using conventional air‑blast sprayers. Calibration of the sprayer should deliver a delivery rate of 0.2–0.3 mm s⁻¹ at a nozzle pressure of 2.5–3.0 bar. Adjust the pressure to produce droplets in the 100–150 µm range; this size ensures penetration into the undersides of leaves without excessive runoff.
Key points for achieving proper coverage:
- Full canopy exposure – spray from multiple angles to reach the upper, middle, and lower leaf layers.
- Leaf wetness – maintain a continuous film of solution for at least 30 seconds on each leaf surface.
- Timing – apply in the early morning or late afternoon when relative humidity is above 70 % to reduce evaporation.
- Re‑application interval – repeat treatment after 7–10 days if mite pressure persists, ensuring the same coverage parameters each time.
- Equipment maintenance – clean nozzles and filters before each use to prevent blockage and uneven spray patterns.
Monitoring after application should include visual inspection for uniform film and, if necessary, a quick water‑sensitive dye test to confirm coverage on the leaf underside. Consistent adherence to these guidelines maximizes the product’s efficacy against spider mites in greenhouse cucumber production.
Timing of Application
Fitover (Fitoverm) must be applied when spider‑mite populations reach the economic threshold, typically 2–3 mites per leaf on the most vulnerable foliage. Early‑season infestations are less damaging; waiting until the threshold is exceeded prevents unnecessary chemical use and reduces resistance pressure.
Temperature influences both mite activity and pesticide efficacy. Apply the product when greenhouse air temperature is between 18 °C and 30 °C; below 15 °C the acaricide remains on the leaf surface longer than needed, above 35 °C rapid degradation occurs. Relative humidity of 60 %–80 % enhances leaf wetness, ensuring adequate coverage.
Leaf age matters. Target the newest fully expanded leaves, as they support the highest reproduction rates. Avoid spraying older, senescent foliage where uptake is minimal.
Re‑application timing depends on environmental conditions and mite pressure:
- Re‑treat after 7–10 days if mite counts remain above threshold.
- Repeat at 14‑day intervals during periods of high temperature (>28 °C) and low humidity (<50 %).
- Apply a second dose 24 hours after rain or any irrigation event that washes off residues.
Monitoring is essential. Conduct weekly inspections, record mite counts, and adjust the schedule accordingly. Consistent timing aligned with mite biology and greenhouse climate maximizes Fitover’s efficacy while minimizing phytotoxic risk.
Frequency of Treatment
Follow-up Applications
When spider mite pressure persists after the initial Fitover (Fitoverm) treatment, a well‑planned series of follow‑up applications is essential for complete control and to prevent resurgence.
The first repeat dose should be applied 7–10 days after the initial spray, provided that leaf samples still show active mite presence. Use the same concentration as the first application unless label instructions specify a reduced rate for subsequent treatments. A second follow‑up may be necessary 14 days after the first repeat if monitoring indicates continued activity.
Key parameters for each additional application:
- Interval: 7–10 days between sprays; adjust based on temperature (higher temperatures accelerate mite development and may require shorter intervals).
- Dosage: Follow label‑recommended rate; avoid exceeding the maximum cumulative amount per growth cycle.
- Coverage: Ensure thorough wetting of both leaf surfaces, especially the undersides where mites congregate.
- Environmental conditions: Apply when temperature is between 18 °C and 30 °C, humidity 50–70 %, and no rain forecast within 6 hours.
Integrate follow‑up sprays with cultural tactics such as humidity regulation, removal of heavily infested leaves, and introduction of biological predators. Rotate Fitover with a product that has a different mode of action after two consecutive applications to mitigate resistance development.
Record each application date, dosage, and observed mite counts. This log enables precise timing of future treatments and validates compliance with label limits, ensuring effective and responsible management of spider mites in cucumber production.
Integrated Pest Management (IPM) Approach
Fitover (also known as Fitoverm) can be integrated into a comprehensive pest‑management program for cucumber crops affected by spider mites in greenhouse production. The IPM framework emphasizes accurate monitoring, threshold‑based interventions, and the combination of cultural, biological, and chemical tactics to minimize reliance on pesticides and delay resistance development.
Effective implementation begins with regular scouting. Use a hand lens or sticky traps to estimate mite populations on the underside of leaves. Record counts per leaf and compare them with an established action threshold (e.g., 5–10 mites per leaf). When the threshold is exceeded, initiate control measures in the following order:
- Cultural practices: Adjust temperature and relative humidity to levels less favorable for mite reproduction (e.g., keep humidity above 60 %). Remove heavily infested foliage and maintain sanitation to reduce mite reservoirs. Rotate cucumber varieties with differing leaf textures to disrupt mite colonization.
- Biological agents: Release predatory mites such as Phytoseiulus persimilis or Neoseiulus californicus at recommended release rates. Ensure compatible environmental conditions and avoid broad‑spectrum insecticides that could harm the predators.
- Chemical control with Fitover: Apply Fitover according to label directions, targeting the mite’s developmental stages. Use the recommended concentration (typically 0.5 %‑1 % active ingredient) and spray until runoff, covering both leaf surfaces. Rotate Fitover with other miticides possessing different modes of action to prevent cross‑resistance. Observe pre‑harvest interval and safety intervals for workers.
- Resistance management: Document each pesticide application, including product name, rate, and date. Rotate chemicals with distinct resistance classes every 3–4 applications. Monitor mite populations for signs of reduced susceptibility and adjust the program accordingly.
Maintain detailed records of scouting data, cultural adjustments, biological releases, and pesticide applications. Analyze trends to refine thresholds and improve decision‑making. By embedding Fitover within this structured IPM approach, greenhouse growers can achieve effective spider mite suppression while preserving crop quality and reducing chemical input.
Post-Treatment Considerations
Monitoring Treatment Effectiveness
Signs of Spider Mite Reduction
Effective application of Fitover to cucumber crops in a greenhouse can be evaluated by observing specific indicators that confirm a decline in spider mite activity.
- A noticeable decrease in the number of mites captured on yellow sticky traps placed throughout the canopy.
- Reduction or disappearance of fine silk webbing on the undersides of leaves and along leaf veins.
- Restoration of leaf coloration, with yellowing or stippling diminishing and the foliage returning to a uniform green tone.
- Lower incidence of leaf bronzing or chlorotic spots that commonly result from mite feeding.
- Improved leaf turgor, evident by reduced wilting and a more rigid leaf structure during midday heat.
Quantitative assessment should include weekly trap counts, comparing pre‑treatment averages with post‑treatment results. A decline of at least 70 % in trap captures within two weeks typically signals successful mite suppression. Additionally, sampling leaf material for mite density (e.g., mites per cm²) provides a direct measure; counts dropping below 5 mites per cm² indicate effective control.
Consistent observation of these signs confirms that the Fitover regimen is reducing spider mite populations and supporting healthier cucumber growth in the greenhouse environment.
Re-evaluation of Treatment Strategy
A systematic review of the current Fitover (Fitoverm) program is essential before any adjustment. Begin by confirming that the product is still registered for cucumber spider‑mite control and that the label‑specified concentration (typically 0.5 ml L‑1) matches the preparation used in the greenhouse. Verify that the spray equipment delivers a uniform droplet size of 100–150 µm, which maximizes leaf coverage without causing runoff.
Collect quantitative data from the past three treatment cycles:
- Number of applications per cycle
- Interval between applications (days)
- Recorded mite counts before and after each spray
- Environmental parameters (temperature, relative humidity, leaf wetness duration)
Analyze this dataset to identify trends such as diminishing efficacy, possible resistance development, or suboptimal timing relative to mite population peaks.
If the analysis reveals reduced mortality rates, adjust the strategy as follows:
- Extend the pre‑emptive interval to 7–10 days after the first detected infestation, ensuring applications coincide with the early mobile stage of the mite.
- Incorporate a short‑acting miticide with a different mode of action for rotation, reducing selection pressure on the spider mite population.
- Increase canopy coverage by calibrating nozzle flow rates and verifying that spray volume reaches the undersides of leaves where mites reside.
- Implement a weekly scouting protocol using a leaf‑blade sample of 10 cm² per plant, counting live mites under a stereomicroscope to maintain a threshold of ≤5 mites per leaf before each application.
Document each modification in a treatment log, noting the date, dosage, environmental conditions, and observed mite mortality. Regular review of this log will confirm whether the revised approach restores control levels to the target efficacy of >90 % mortality within 48 hours of application.
Harvest Interval and Residue
Waiting Period After Application
After spraying Fitover (Fitoverm) on cucumber crops to control spider mites, observe the mandatory waiting period before harvest and re‑entry. The pre‑harvest interval (PHI) established by regulatory agencies is 7 days for leafy greens and 14 days for fruiting cucumbers; adhere to the longer interval when fruit is the marketable product. During this time, residues decline to levels below the maximum residue limit (MRL) defined for consumer safety.
The re‑entry interval (REI) for personnel entering the greenhouse is 2 hours after application, provided that protective clothing is worn. Workers must avoid direct contact with wet foliage and refrain from eating, drinking, or smoking in the treated area until the spray has dried.
Environmental conditions influence the degradation rate. Higher temperatures (above 25 °C) and moderate humidity (50‑70 %) accelerate breakdown, potentially allowing a slight reduction in PHI under strict monitoring. Conversely, low temperatures and high humidity prolong residue persistence; in such cases, maintain the full PHI.
Record the application date, formulation batch number, and observed weather conditions in the greenhouse log. This documentation supports compliance audits and facilitates adjustments to future treatment schedules.
Key points to implement:
- PHI: 14 days for cucumber fruit, 7 days for leaves.
- REI: 2 hours with PPE, no direct contact with wet material.
- Monitor temperature and humidity; adjust only with validated data.
- Log all application details for traceability.
Ensuring Food Safety
Fitover (Fitoverm) is a systemic acaricide applied to cucumber crops to control spider mites. Food safety depends on strict adherence to label‑specified residue limits, correct dosage, and thorough equipment sanitation.
Before spraying, verify that the product batch is within its expiration date and that the greenhouse environment meets temperature and humidity parameters recommended for optimal absorption. Use calibrated sprayers to deliver the exact volume per hectare indicated on the label. Wear approved personal protective equipment, and keep a log of application date, time, and concentration.
Apply the product at the growth stage when fruit is not yet mature, ensuring full leaf coverage while avoiding direct contact with developing cucumbers. Follow these steps:
- Prepare the spray solution using the precise water‑to‑product ratio.
- Conduct a test spray on a small area to confirm uniform distribution.
- Execute the application during the early morning or late afternoon to reduce plant stress.
- Clean all spray equipment immediately after use to prevent cross‑contamination.
After treatment, conduct residue analysis according to local regulatory methods before harvesting. Implement a washing protocol that includes rinsing cucumbers with potable water and, if required, a mild detergent approved for produce. Store harvested fruit at temperatures that inhibit mite resurgence and preserve product integrity. Maintaining these practices guarantees that cucumbers treated with Fitover meet safety standards for consumer consumption.
