This is a picture of one of my eggplants which looks pretty unhappy. I have what I believe to be septoria leaf spot on my tomatoes (looks similar) which I am treating with some success with Chlorothalonil (sp) aka Daconil, however the label on that product does not list eggplant as a plant on which it can be used. I have been using a copper fungicide on the eggplant (also on my peppers) which I do not find to be as effective as the Chlorothalonil. I use a drip watering system to minimize any chance of wetting the leaves as much as possible (of course when it rains, which it has quite a bit this year, there is not much I can do about the plants getting wet)

Does anyone know of anything else I can/should do? I doubt there is much I can do anymore this year but I would like to minimize this problem next year. Is there a fungicide I can apply to the soil before I set out the plants next year? How about baking the soil by applying a sheet of clear plastic a couple of weeks before I set out the plants?

Any thoughts very much appreciated
