I live in the north but somehow Southern Blight got me.
My 2 pepper plants (down from 3 after the friggin cutworms!) have not been looking good lately. They were wilting and some of the leaves have been falling off. I've been looking up all the "wilt" disorders and none of them seemed to fit. This morning I decided that one of the pepper plants was just too sad looking and too close to my eggplant to mess around. I pulled it up and there was this white crystal-y, moldy, fungus looking stuff at the base of the plant. A little googling turned up Southern Blight. I probably need to pull out the other pepper plant too so it doesn't affect my tomatoes and eggplants.
This sucks. For two years in a row now I can't grow red peppers for the life of me!
