Something is ailing my Celebritys, but not the Romas right next to them. Some branches turning brown, some not. One leaf has it, the other one doesn't. No evidence of mites or aphids. In fact insects havent been a problem at all. Fruit not affected at all. Still getting some blooming and fruit set, just less cause so much of plant is sick. Using organic fertilizer, compost, mulch
I'm not sure, but I've heard rumors of a blight originating with seed from a certain supplier (a lot of people at Agway were comparing notes & complaining). The one BIG grower that seems to be affected most, was Bonnie plants (usually in peat pots). It's just not a good tomato year.
