*OMRI listed

  1. Grapes – Imidan PHI is rate dependent
  2. 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.
  3. 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!
