My cucumbers are wilting. It seems only parts of the vines are doing this and it seems to be starting from the leaves back. Within one day two vines have withered to the point of death. I noticed my zucchini is doing similar but not to the same extreme. There are potato bugs on them. I didnt think there were enough to worry about the plants. There's also another bug that I always called a stink bug. It looks like a prehistoric thing. The front is pointy, it has legs kind of like a gran daddy long legs, and has a hard shell type diamond shaped back. Could either of these bugs be causing the damage? I havent seen the stink bug on the zucchini. Any ideas?
