How to dilute Fitosverm for spraying eggplants against spider mite? - briefly
Mix 5 ml of Fitosverm concentrate with 1 liter of water (or 0.5 ml per 100 ml for smaller volumes), stir until uniform, and apply to eggplant foliage until runoff, repeating every 7–10 days during infestation. Use the dilution ratio indicated on the product label and ensure thorough coverage of leaves, especially the undersides.
How to dilute Fitosverm for spraying eggplants against spider mite? - in detail
Fitosverm is a copper‑based liquid fungicide that also acts as an acaricide. When preparing a spray for eggplant plants infested with spider mites, follow these precise steps.
Measure the product according to the label recommendation for mite control, typically 2 ml per litre of water. Use a calibrated syringe or a graduated dropper to ensure accuracy. Fill a clean spray tank with the required volume of water—room‑temperature tap water is suitable. Add the measured Fitosverm to the tank, then stir or agitate the mixture for at least one minute until a uniform solution forms. Avoid vigorous shaking that could create foam.
Before application, check the pH of the solution; a range of 6.0–7.0 maximizes copper availability. If the water is overly acidic, add a small amount of agricultural lime (calcium carbonate) at a rate of 0.5 g per litre, then remix.
Apply the spray in the early morning or late afternoon when leaf temperature is below 30 °C. Use a fine‑mist nozzle to achieve complete coverage of both leaf surfaces, especially the undersides where spider mites reside. Treat the entire canopy, ensuring that the solution reaches the petioles and stem bases.
Repeat the treatment every 7–10 days until mite populations fall below economic thresholds. After each application, flush the spray equipment with clean water to prevent copper buildup.
Store any remaining concentrate in a tightly sealed container, away from direct sunlight and temperatures above 25 °C. Label the container with the dilution ratio and the date of preparation. Dispose of empty containers according to local regulations for hazardous waste.
