We have had a lot of rain this month, but it is still cool here (PA). I fought the blight a couple of years ago when it was brought in on Bonnie plants. That was so miserable and the tomatoes were pretty much tasteless.

I started growing my own after that, but didn't do so this year. Hope it isn't too late to spray.

recommend some organic sprays?

If you Google organic tomato fungicides, you find products by Safer, copper sprays, some use baking soda, some powdered milk sprays. There is no substitute for good garden cleanliness (mulch early, keep soil off of the foliage, use bleached containers, etc) - but in hot humid areas fungal attacks are inevitable. Even those who blast with chemicals like Daconil find it isn't at all foolproof...

I tend to be a non-sprayer - of anything. Then again, with 200 tomato plants, I've got lots of redundancy. Disease is far less an area of expertise for me than histories and varieties - my view is to play with Google, which may send you to places like Tomatoville and Gardenweb - where you can see what others do.

Good luck!

As in Raleigh, Durham humidity plays merry hell with some plants. I don't have 200 tomatoes (wish I had room), but I want to keep the few I've got healthy. I'm off to Tomatoville!

It has been a lousy year for the hot weather plants so far. So much rain, cool weather.

Good luck in keeping those diseases at bay.
