How should Fitoverm be diluted for indoor flowers to control spider mites? - briefly
Mix 0.5 ml of Fitoverm with 1 L of water, stir until uniform, and spray foliage until runoff. Re‑treat every 7‑10 days while spider‑mite activity persists.
How should Fitoverm be diluted for indoor flowers to control spider mites? - in detail
Fitoverm, a miticidal formulation based on abamectin, requires precise dilution to be effective against spider mite infestations on indoor ornamental plants. The recommended concentration for foliar sprays on potted flowering species is 5 ml of product per 10 l of water, delivering an active ingredient rate of approximately 0.025 % (w/v). This dosage provides adequate coverage while minimizing phytotoxic risk.
The mixing procedure should follow these steps:
- Measure 5 ml of «Fitoverm» with a calibrated syringe or graduated cylinder.
- Add the measured volume to a clean container containing 5 l of lukewarm water (20‑25 °C).
- Stir gently for 30 seconds to ensure uniform distribution.
- Introduce the remaining 5 l of water, continuing gentle agitation for an additional minute.
- Verify complete dissolution; no residue should remain at the bottom of the container.
Application guidelines:
- Apply the solution to the entire canopy, ensuring both upper and lower leaf surfaces are wetted.
- Use a fine‑mist spray nozzle delivering droplets of 100‑150 µm to promote leaf retention.
- Conduct the first spray in the early morning or late afternoon to reduce evaporation and leaf burn.
- Repeat applications at 7‑day intervals for three consecutive treatments; extend to a 14‑day interval if mite populations decline below economic thresholds.
Safety and post‑application considerations:
- Wear protective gloves and goggles during preparation and spraying.
- Keep the mixture away from open flames; abamectin is flammable in concentrated form.
- Do not apply to stressed or wilted plants; monitor for any signs of chlorosis within 48 hours.
- Store any unused solution in a sealed container, labeled, and discard after 24 hours to prevent degradation.
Following the specified dilution and application protocol maximizes mite control while preserving plant health and indoor air quality.
