Does anyone have a picture of what herbicide drift does to tomatoes? It is probably not the problem, because it is only one plant. I think it is probably blight. I don't have a pic cause I fell while out working on it. I'm old and don't bounce anymore. Some of the branches had completely browned and dried up to a soggy looking stump on the stem. Some leaves are yellow, some green but curled. This was after it was watered. I found absolutely no evidence of insect damage.
