George, my local guru gave me explicit instructions for your borer situation: Go out after dark with a strong light and a lady's hat pin plus a single-edge razor blade. Zucchini stems are transluscent, and you will be able to spot a borer inside, close to the inner wall of the plant. You then have a choice: you can insert the hat pin many times in a complete circle around the zuke stem, and he should become mortally wounded and drop down inside the stem. The other choice is to make a 3 inch slit in the stem OPPOSITE THE CRITTER, open it up a bit, reach inside and mash the caterpillar against the wall it clings to, using the razor. Sounds daunting. Since all the nutrient factors flow vertically in a zucchini, the fact that you are making a slit should not kill the plant. If they get into the roots, however, it's Goodbye, Charlie.
