In the past, I've used Di-Syston as a granular application to keep pests from bothering shrubs and trees. However, I see that it is no longer available.
I've got a tree with something that keeps "stinging" the branch tips, laying eggs, and then borers or something seem to be eating the tree. It is actually a peach tree, but there won't be any fruit on it until at least next year, so it wouldn't be an issue using something systemic at this point.
Can anyone recommend a granular systemic insecticide to use as a replacement? I couldn't find anything at all like that when I browsed the fair sized garden chemical section at Lowe's this morning.
Thanks!
