I've never been able to grow squash at all due to those damned things.

As far as I know that only works on those worms that feed on cabbage family
plants and horn worms on tomatoes. I can be wrong.

I've tried the slitting and squashing the borers but the plants always
managed to die or were so sick they produced almost nothing afterward even
when the vine was covered with soil. I'd end up ripping them out and
burning them.

The products we have now are almost useless for insect control. The insects
and bugs have developed a good immunity to just about anything you'll find
on the store shelves. Those that worked, like Kelthane for mites, Dursban
and Chlordane were taken off the market - or you need a lic. to purchase
them. I'd like to know what the commercial growers are using.


It's been several years since I've tried.
I wonder if the local population is still bad enough to even attempt
them?
