How should Fitoverm be prepared for treating flowers against spider mites? - briefly
Prepare a Fitoverm solution at the label‑recommended rate (e.g., 0.5 g per litre of water) and spray it thoroughly on foliage until runoff, preferably in the early morning or late evening. Re‑apply every 7–10 days until spider mite numbers fall below the economic threshold.
How should Fitoverm be prepared for treating flowers against spider mites? - in detail
Fitoverm must be mixed with water before application. Use a clean container, add the recommended amount of product—typically 5 ml per liter of water for most ornamental species. Stir until the solution is uniform; do not shake vigorously, as excessive agitation can cause foaming.
Temperature of the dilution water should be between 15 °C and 25 °C. Cooler water reduces phytotoxic risk, while warmer water improves solubility. Verify the temperature with a calibrated thermometer before mixing.
Apply the solution with a fine‑mist sprayer, ensuring complete coverage of leaf surfaces, including the undersides where spider mites reside. Spray until runoff begins, but avoid excessive dripping that can promote fungal growth.
Re‑treatment intervals depend on infestation severity. For light populations, repeat application after seven days; for heavy infestations, schedule a second dose after three to five days. Do not exceed four applications within a 30‑day period to prevent resistance buildup.
After each use, rinse the sprayer thoroughly with clean water and store the remaining Fitoverm in a sealed, dark container at 4 °C–10 °C. Label the container with the preparation date and concentration to maintain traceability.
