Question
I live in Ontario and my grapevine is being eaten by very small black/brown
caterpillars/grubs? and I'm not sure what they are or how to get rid of them. The
leaves are full of holes and dry brown spots and are curling up. Any ideas?

Answer
Hi Leila

We have those things where I am also. I am not sure what they are called.  They usually do not eat that much, but they are on muscadines here.  Sevin insecticide should get rid of them. It is labeled for grapes, at least in the US.  I hope this helps.
