Notes
- Product names are listed as examples only. There may be numerous product options for some active ingredients.
- Experience has shown that use of pyrethroid insecticides is associated with subsequent spider mite outbreaks. Therefore, monitor fields closely after using these materials.
- Check current label for application options (i.e. aerial vs. ground only), restrictions, re-entry intervals, pollinator safety, groundwater and stream buffer requirements, application timing, etc.
- To avoid resistance, growers are advised to not use repeated application of the same active ingredient or repeated use of chemicals in the same mode of action group.
Note: Products are listed in alphabetical order and not in order of preference or superiority of pest control.
Many insects have export restrictions, but the pests listed as export pests do not cause tree damage so are listed separately.
