Here is a FAQ from Cornell that you may find useful, especially Question #18. Questions #14 and #15 may help you decide how best to dispose of the diseased plants:

Today I put tomato plant that I lost to late blight in black garbage bag and tossed it into garbage can that's kept in garage.

I'll yank it out tomorrow morning and put it out in the sunlight, if there is any, to bake off nasty stuff.

With all the critters around I'll have to bring it inside for the night.

This is a real pain after losing the one bush with over 20 nearly ripe tomatoes. I had considered drenching plants again with Daconil as I did when plants were very young and I read about the 'ate blight situation. Hesitated because I was worried about Daconil being on the tomatoes.

Just read in Cornell bulletin it could've been washed off. Even so, I'd still feel uneasy about serving tomatoes that had been drenched with Daconil to anyone even though I already wash tomatoes with soapy water before anyone eats them.

Let's hope for a better year in 2010.
