All about wilt diseases -- starting with coastal VA almost NC
At Carolyn's suggestion, I thought I'd start a thread for general wilt-related discussions. Back in Richmond, I never had these problems, but since moving to the coast I've had repeated heartbreak from a disease that comes on quickly, wilting a portion of a healthy, beautiful plant, followed by death of the whole plant within a week. My best guesses are Bacterial Wilt and Fusarium Wilt. Of course, I could have experienced both in different seasons and am just treating them as one disease in my mind. I have had this experience with both hybrids (better boy, early girl, beefmaster) and OP varieties (Aunt Gertie's Gold, now maybe Cherokee Purple.) I'll try to post good post-mortem images if and when the CP goes down. If I have time today I'll pull out the good digital camera and see if I can find a host site for photos.
To put it in context, other than some insignificant foliage imperfections and a spot of BER on one plant in a pot that didn't get water, I have a very healthy, vigorous bunch of well-nourished and minimally stressed plants. I don't use Daconil or much of anything else from the store, but I do make compost tea and foliar feed with that, and I've sprayed with a homemade aspirin spray, as I read that it might help boost resistance. I'm growing many varieties this year in hopes of finding the best ones for this area and this garden.
Your experiences welcome.
