Spaying Sevin for Japanese Beetles
Yesterday I sprayed liquid Sevin on my new Prairiefire Crab to control the Japanese Beetles that defoliated the tree last year. There has been no rain, but today, I still see Japanese Beetles on the leaves. Do I need to spray every day? Or will the beetles die as they eat the leaves that have the Sevin residue on them?

This insecticide will kill insects that eat the Sevin residue on the plant unless it is washed away. You need to read the instructions on the Sevin label regarding spraying intervals. The website below gives the official EPA label. Scroll down to Apple trees. It states the frequency interval for Apple trees if it is not listed on your product. You should spray when bees are not present ..early morning or evening....mow any flowering plants near the tree. Your formula of Sevin may have additional instructions. The second website is questions and answers from the company that makes Sevin. CAUTION: Mention of a pesticide or use of a pesticide label is for educational purposes only. Always follow the pesticide label directions attached to the pesticide container you are using. Remember, the label is the law. Be sure that the plant you wish to treat is listed on the label of the pesticide you intend to use. Also be sure to observe the number of days between pesticide application and when you can harvest your crop.
