Has anyone tried applying surround sprays (meant for fruit trees) to the vines of zucchini plants to protect them from the squash vine borer? How about using panty hose wrapped up the stem? I am determined to beat the little buggers this year!!

Andrea, are you asking about the Kaolin spray family of products? My understanding is that Surround may be a brand name of one of those products.

I don't have any experience with those, but there are several people on this thread about squash vine borers who have experimented with mechanical wraps like tinfoil and veterinary wrap.'

My own bugaboo is powdery mildew; my plants don't seem to last long enough to get the borers. This year I am trying a bunch of different summer squashes to try and find one that can withstand the mildew.

Wrapping squash vines? That sounds like an enormous amount of work honestly lol. Of all the things I've ever grown I've never had an issue with squash. I always let the areas around squash grow a little wild. I can only assume some other thing comes in and eats whatever would damage the squash. I lose a squash or two here and there but they're so prolific I've never noticed the difference.

What about organic pesticides for spot treatment? Or DE? Each would knock down the initial infestation, wash it off shortly after to not hurt the good bugs, then the lowered pest population can be kept in check by predators.

How lucky are you, Blake! The organic means you mentioned are useless. Their method of attack is really quite ingenious. If they weren't so destructive, I would have a deep respect for them. I have hope in mechanical means, however and am planning on experimenting with them this year. It is work, but the plants are so productive (and so tasty!!) that I consider it a good use of my time. Dan, you are correct, I was speaking of Kaolin sprays. If it works with squash and peaches both, it may go down with DE as a must-have product. Perhaps one of these days my local government will stop being so asinine about owning chickens and I can get a bit of help with my buggy population. I know there are varieties out there that are better to plant, but I am a sucker for zucchini. And acorn squash. And spaghetti squash... All of them!

Borers are terrible here. The sum total of my experience in this borer-infested hole and numerous conversations with gardeners is:
1) Plant early and late
2) Bury the nodes so the vine puts out more roots

Obviously those aren't going to be foolproof. Please let us know if you find something that works!
