Peach Tree Shoot Strike (Twig Flagging)
Hi everyone, I just noticed the new growth at the tip of my peach tree is drying. the new leaves would lose vigor and then just dry up.
After some research, I think I have twig borer problem, can anyone confirm? I already applied dormant spray in winter but that didn't seem to help prevent the borers from chewing up the new shoots. Also I live in Canada and our provincial government has banned the use of pesticide so I can't really spray anything.
I bought Bacillus Thuringiensis (bt) spray from Ebay, I hope border custom doesn't block it, do you think this product will be helpful? When do I spray and what are other organic pest control methods I can try? thanks!
