My wife got some "ginger beer" but I didn't like it at all; gave it to a friend.

The acorn squash is dead -- however, someone very helpfully told me about a 10% milk solution, which I sprayed yesterday just before a rain, and today it looks much better! The powdery mildew is going away, but now there's some sort of yellow spots on the cucumber leaves, and I think the squash also. I'll take pictures tomorrow.
