Will the Monterey Once a Year Insect Control kill my columnar aspen?

I used your product on my columnar aspen trees and they started dropping a lot of leaves. Will your product kill my trees?


The Monterey Once a Year Insect Control should not have any negative effects on plants to cause them harm. You should contact the manufacturer for further troubleshooting on what could be occuring to your plants that you treated. You can reach the manufacturer at 559-499-2100.
