I have a horrible time with borers in my cukes and summer squash every year. For a few years I've been wanting to try a product offered by Gardens Alive-injectable nematodes: http://www.gardensalive.com/product.asp?pn=2877
I ordered some today to keep on hand as a last resort. You're supposed to inject the nematode solution into the opening created by the borer and then the nematodes are supposed to kill the borer, you then cover the affected stem with dirt and supposedly it keeps growing just like nothing ever happened!? I look at this stuff every year but have never tried it. Has anyone here tried it? The Rodale Color Handbook of Garden Insects (by Anna Carr. It's pretty old-1979) says to slit the stem and kill the borer, then cover the vine with soil-I have tried this method with absolutely no success, I use a square foot gardening growing method and have had trouble with barriers and fertilization of flowers-besides, I thought I read somewhere that the borers overwinter in the ground anyway-if this is the case, the barrier would keep new moths out but wouldn't the over wintereing ones be trapped inside the barrier?
Anyway, I would really appreciate any suggestions . . .
Thanks!
