Chemical Classification & Pesticide Resistance Management


For the pesticide products recommended in this Guide, the following table groups the products according to their Group Number or Letter and presents the Trade Names and Chemical Names for each pesticide product. The column titled Notes indicates those chemicals for which resistance (R) is present in one or more pest populations (insect, mite, plant disease, or weed) in the Interior fruit-growing areas.

Pesticide Resistance Management

The Pest Management Regulatory Agency (PMRA) has adopted a numerical classification system for fungicides, herbicides and insecticides/miticides based on their primary site of action. All pesticide products have a Group number/letter and the type of pesticide (fungicide, herbicide, insecticide) displayed on the label.

GROUP 4 INSECTICIDE

Use these Chemical Group numbers or letters to select pesticides as part of a pesticide resistance management program. Avoid repeating the use of pesticides with the same Group Number during the same season, as this practice will select for resistant individuals or strains within a population. Pest resistance to one product within a class or number group with a single site of action will lead to resistance to all products within that class or group. Also refer to the tables on Relative Toxicity of Pesticides for information on the relative toxicity ratings of insecticides and miticides to common beneficial mites and insects.
