When should I start spraying Malathion 57% for squash borers?
I see on your label that this product will rid squash borers. When would I spray the squash to prevent the infestation from starting? And do I spray under the leaves or on the base? Help!
According to the Malathion 57% product label, you should start spraying when you see evidence of insect activity. It is very important to spray the entire plant including the underside of the leaves where many of these insects tend to harbor.
