In the past, I've used Di-Syston as a granular application to keep

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!


Lindane. (it's a spray)


I was under the impression Lindane was no longer available to the home
gardener - correction welcome, though.

You are right. Bonide still sells "Borer-Miner Killer" that used to
be 20% Lindane, but now they don't say what the active ingredient is.

A little searching turned up that it's Permethrin 2.5% (I haven't
verified this); not sure how effective that is. At least it's not
imidacloprid.
