*OMRI listed
- Grapes – Imidan PHI is rate dependent
- For Berries: allowed up to the first 3 weeks after fruit set. Application of plain water via normal sprayer prior to harvest can help to reduce Surround WP residues. For Grapes: table grapes, do not spray after first bloom; Wine grapes sprayed up to veraison will have minimal adherence to berries. Applications after veraison will adhere more to grape berries.
- Short residual toxicity time. Prohibited from onset of flowering until flowering is complete. Application only made between 2 hours prior to sunset and 8 hours prior to sunrise.
PHI= pre-harvest interval; time between last application and harvest
REI= Restricted entry interval; time between application and when workers may re-enter the field
Probable efficacy ratings based on lab and field assays in western USA, Michigan, Connecticut
Additional materials labeled for SWD control with a probable efficacy of poor are not listed.
- Add 2 lbs sugar/100 gal to increase SWD interaction with pesticides.
- Add 4-16 oz Nu Film P/100 gal with all materials to improve SWD efficacy.
- If it rains, re-apply a pesticide material. Read the label for any re-application restrictions of the same material.
This is a guide. ALWAYS check the label!
