Read the label. The label will possibly mention other target pests and/or how to avoid killing beneficial insects.

While CCE cannot recommend specific retailers, there are several nurseries within NYS and New England that sell bare-root fruit stock. The deadline is approaching for getting orders in since most nurseries start shipping in early April. Below is a list of apple varieties recommended by Dale for Long Island; the nursery will also be able to assist with pest-resistant suggestions for any fruit species. You could additionally go to your local retail garden center and see what they sell and talk with a horticulturalist. I'm assuming this is for a home garden, so you can also reach out to Sandra and Alice at the Home Hort Diagnostic Lab for additional information.
