CapeCodGardene,
Glad I could help
TwinLakesChef,
Well, for Late Blight there's not much you can do except good air circulation and prayers for good weather. Last year, I do admit to talking to the lake effect clouds to not come my way
. If you do see Late Blight on a plant, bag and remove the plant immediately. If caught early, some plants can possibly be saved. Now, thankfully, Late Blight isn't as common of a disease. You really do need long periods of cool damp weather for it to happen. Most summers are not like that.
For Early Blight, again good air circulation is important. Being organic, I used copper fungicide. Copper is still fairly toxic, so I try to use it only when needed. There are chemical fungicides for Early Blight like Daconil. I'm sure there are others available at garden center. Many people will tell you to only water from the bottom also, but I find that sort of silly since rain comes down and you can't prevent that. Watering early in the day is recommended instead of the evening because excess moisture would dry up during the day. Again, it rains here at night more than the day so I don't bother. In another area, it might work better. But good fall clean up is important because of overwintering spores.
Hope that helps,
Remy
