>>805621You could have a virus, or you could have squash vine borers. I don't get the borers here, so google would be a better consultant on diagnosing it. What I do get, that can totally wreck squash, is pic related. That pic has both nymphs (young) and adult squash bugs. They stink like fuck, and will destroy a squash plant. A lot of times, you notice them because of dying, yellowing leaves, then you flip it over, and you see those stinky motherfuckers fucking your shit up. I hate them with a passion and would genocide the entire fucking useless species if I could.
