Includes management options for commercial and home use.

In all cases, follow the instructions on the pesticide label. The PNW Insect Management Handbook has no legal status, whereas the pesticide label is a legal document. Read the product label before making any pesticide applications.

Pre-mixed pesticide combinations

Commercially packaged insecticide premixes should not be used in commercial orchard crops from a pesticide resistance management perspective. To prolong the effectiveness of insecticides, an effective insect resistance management program must be part of an IPM program that involves sampling and monitoring, treatment thresholds, biological and cultural control. Do not use pesticides with the same mode of action on back-to-back generations of a pest. Home orchardists should seek to identify specific pests and select appropriate pesticides for the targeted pest.

Notes

All rates listed are for formulated products, unless specifically stated otherwise.

Use pesticides safely!

  • Wear protective clothing and safety devices as recommended on the label. Bathe or shower after each use.
  • Read the pesticide label—even if you’ve used the pesticide before. Follow closely the instructions on the label (and any other directions you have).
  • Be cautious when you apply pesticides. Know your legal responsibility as a pesticide applicator. You may be liable for injury or damage resulting from pesticide use.
