I think once you get botrytis its probably not going to make it (the gray stemrot in your tomatos). I've never seen the stuff spread myself, but once one plant shows it its time to make sure they all get dryer by evening. This particular fungus occurs naturally, but seems to get more active when you have a cool evening and the plants go to bed too wet. There are soil ammendments like soil guard which can help with both it and fusarium, and verticillium but they are prophalactics not cures. With some plants I had some success fending off botrytis and verticillium by adding some ground seashell mix to the soil (the extra calcium seems to inhibit fungal growth) - but once either got too far it not much you could do. For mildew, if your weather is cool we did have a lot of luck spraying elemental sulphur, but if you have really hot days I'd be wary of it because it can stress the plants by upsetting potassium balance in the leaves. Liz is probably right though, about just removing them, me I find it harder to give up them up since I don't grow as many. --- On Sun, 7/5/09, Liz <liz@allslash.org> wrote:
