Grafted tomatoes don't necessarily provide any more protection against early blight than do non-grafted plants since the spores are airborne. At best, depending on the rootstock you used, you might increase the resistance a minimal amount and so delay the onset by a few days exposure. Defiant and Legend are the two varieties listed as the most EB tolerant, not resistant, "tolerant".

The use of Daconil and similar fungicides from the day of plant-out has proven to be far more effective as a preventative measure.

That said if you want to try doing it then check out the other discussion on grafting just down the page. In it I included a good how-to-do-it link as well as links to the many other discussions here on grafted tomatoes.

Thanks for the link Dave! I get all warped out of shape when I begin to think of all those beautiful transplants I've planted, only to watch them, one by one, fall prey to EB...... Obviously, grafting isn't going to solve my problem.......

Daconil is my fungicide of choice & I spray it early & often, but I wonder if I'm actually spraying it starting with day one. Me thinks not.......

I will also try Defiant & Legend..... Last year I planted my usual (15 each) Celebrity, Mountain Fresh, & Jet Star. Mountain Fresh was the most EB resistant, but still succumbed......

Still might try grafting a few Defiant or Legend for fun.....
