You're probably right. We've had tons of rain too, perfect for tomato plant
fungus. Even if it sits on the plants for a couple of hours - it should be
dry, shouldn't it? Different fungicides may be different though. Sometimes
I've had to get stuff on, no matter how rotten the timing, so I wouldn't
wait too long. Have you checked Jack & Lum's sites for any info on
black-rot? Or your county agricultural agent? Good-luck.
