How to prepare a solution of Fitosverm for spraying eggplants for spider mite control? - briefly
Dissolve the recommended dose of Fitosverm concentrate (typically 5 ml) in one litre of water to obtain the proper concentration for eggplant foliage. Apply the solution thoroughly to both leaf surfaces until runoff, preferably during early morning or late afternoon, and repeat every five to seven days until spider mite numbers drop.
How to prepare a solution of Fitosverm for spraying eggplants for spider mite control? - in detail
Preparing a Fitosverm spray for eggplant spider‑mite control requires precise measurement, thorough mixing, and adherence to safety standards.
Materials:
- Fitosverm concentrate (commercial formulation)
- Clean water, preferably de‑ionised or soft tap water
- Graduated cylinder or measuring cup for liquids
- Plastic or glass mixing container with lid
- Protective gloves, goggles, and mask
Dosage calculation:
- Determine leaf area to be treated; a typical recommendation is 2 ml of concentrate per 10 l of water.
- Multiply the required volume of water by the dosage factor (0.2 ml l⁻¹).
- Adjust for concentration variations indicated on the product label.
Mixing procedure:
- Fill the container with the calculated water volume, leaving space for the concentrate.
- Add the measured Fitosverm dose slowly while stirring gently to ensure uniform distribution.
- Continue stirring for 1–2 minutes until the solution appears homogenous and no droplets remain on the container walls.
- Allow the mixture to stand for 10 minutes to settle any air bubbles.
Application guidelines:
- Apply the spray in the early morning or late afternoon when leaf temperature is below 25 °C to reduce phytotoxic risk.
- Use a fine‑mist sprayer, covering both upper and lower leaf surfaces uniformly.
- Repeat treatments every 5–7 days until mite populations fall below economic thresholds.
Safety and storage:
- Wear gloves, goggles, and a mask throughout preparation and application.
- Store any unused concentrate in a cool, dark place, sealed tightly to prevent degradation.
- Dispose of empty containers according to local hazardous‑waste regulations.
Following these steps ensures an effective, consistent treatment of eggplant foliage against spider mites while minimizing plant stress and environmental impact.
