I have it on the eating tomatoes, not the big ones yet. You need to spray with a preventative fungicide, no cure I know of.

Are you mulching. I plant my tomatoes in black plastic so the water can not splash soil up on the leaves.

I could write an article on this- and I have.
Early prevention, blight resistant varieties, spray program, thinning, proper disposal of any plant material, ground cover- mulch or plastic. Basically all the usual disease prevention stuff. And if possible, cover them from heavy dew or sustained rain. Here on the west coast that can be a real battle. Green house is ideal.
Now if I would just do that for my pumpkins!
I don't use much in the way of synthetics chemicals on my food crops. One of the best "tricks" with tomatoes is to hit them before the fruit are very large with a Bordeaux mixture and then a sulfur and then a bacterial anti-fungal like Serenade. I do that here in early July as we usually don't get fruit until later in the month.
But again, disease resistant varieties is a big part of a happy tomato garden. What types are you growing? There is this huge allure now for the "heritage" varieties. Sure, but there is a reason for the more modern hybrids.

It seems that this is going to be a problem every year. After having my late tomatoes wiped out for a couple of years, I have had good luck with the variety 'Defiant' for late crops. I can usually get my main crop of tomatoes in before late blight hits. Knock on wood. (I don't spray)
Linus and Cavity search, I agree with the mulching to prevent most blights and diseases. It has been my experience that the late blight can't be stopped that way. I believe it is airborne and does not overwinter in the soil.

I have been having good success using Pentathlon(Mancozeb) with a little AgriFos. I sometimes rotate the Pentathlon with Daconil(Fungonil). AgriFos is a great systemic and gives your plants a second line of defense when you get those heavy rains that wash off the contacts and yes it is safe for garden veggies. It is labeled for many edibles. My neighbor lost all of his plants 2 weeks ago using just Daconil but there is no sign of blight on my plants.

Also, I meant to add that when you consider your crop rotation for the tomatoes you should include the potatoes in that plan as they harbor the same disease.
Icheckon, one of the peculiarities of the late blight is that it can be very hit and miss. Soil and watering difference between you and your neighbor can make all the difference.
Here is one of the better articles I have read.

Potato blight is a fascinating read for you garden disease geeks out there. It brought my Irish ancestors to America. I do love potatoes.

There is not a spray or prevention for 12 inches of rain at peak plant time.

My tomatoes look better this year than ever before.Blight is a real problem here too.I used a spray rotation of Daconil,Copper soap,Agri-Fos and a new product Pageant.The Pageant seems to really make a difference and it was approved for tomatoes in July of 2013.My tomatoes have very little blight and I have noticed my neighbors tomatoes, which they do not spray, are almost gone now from blight.
