My mother has a three year old tame blackberry bush that is blooming for the first time. Baby blackberries are developing, and mother discovered a green worm eating the fruit yesterday. She's not a happy camper, I might add....
My question is, what type of pesticide can I use to get rid of the worms. I need an answer as soon as possible, before mother decides to wage war on the worms and end up killing the blackberry bush.
