Well here's the update I promised.
Well it's not so good. Two years ago I had at least a 35% infection. After skipping a year and not planting anything I now have maybe a 5 to 10 percent infection. Mainly in the sandy soil area. My garden is red clay, loam, and sandy soil. They aren't hardly found in the red clay area, and some in the loam, but they are heavy in the sandy area.
Better to Bee; I may have to give that a try. The plants they hit the hardest this time are the okra and snap beans. They didn't bother the purple hull or the corn. I have some peppers, squash, and zucchini, planted in the sandy area as well. I'll soon pull those up to check and will report back. Another thing I'm doing this year is as soon as the row plays out I'm plowing it up. I figure that's doing away with the food source.
