Jim. I agree with what PB said for teh most part, but it's not the green clover worm that's stripping our beans.....it's those damn fuzzy caterpillars (at least here it is).

My beans are at R7, so I doubt they'll do much damage, but the picture of the plane over my neighbors field is real and took place on Saturday.  The neighbor's beans are double cropped, planted about 6 weeks behind mine.
