A pestilence of Biblical proportions

These photos are of the beans and are not doctored. I finally sprayed the corn and potatoes Friday with Seven. I didn't spray the beans and peas because we are picking them now. Saturday morning I found tons of grasshoppers dead in between the rows of corn and potatoes, but just as many or more were alive and eating away on the same plants. The neighbour behind the garden just baled his second cutting of hay and all of the grasshoppers have moved to the garden. My biggest concern is the fact that the corn is starting to tassel out and the grasshoppers love the tassels and silk when it forms on the ears. It is going to be interesting to see how this turns out.
