That is helpful, I grow lots of garlic and it would be a less expensive "cure". AM quite sure it is a peach borer, but we had a very wet early summer so the water intake could be part of the problem. I pruned out a few of the low branches that were full of "jelly" and found no more at present, but will file the sulfuric suggestion in case it appears again later. Will also try the sharp wire. Thanks.
Just wondering, could it be related to the massive infestation of 17 year locusts that occured in our area this spring? I have many old oaks and the numbers of insects were almost frightening as they crawled to the surface, matured, and bred and laid eggs on young branches. Much damage appears on the oaks and some lilac and young shrubs.
