Argh! Looks like Late Blight has arrived on our big paste tomato planting. No, I didn't do preventative spraying. Yes, I do farm organically, but no, not USDA certified. What can I do now?

So far, it is sporadic lesions on leaves of some of the plants, and the weather forecast is hot and dry. (They have drip irrigation) We're trying removing all the damage once a day every day for a week, while the sun is beating down and the UV will sterilize the spores. Has anyone ever had success with this?

Has anyone had success with compost tea, seaweed sprays or other beneficial foliar sprays?

Has anyone had success after the fact, with Sonata, Oxidate or any of the other organically approved sprays?

The fruits are only just starting to ripen, so if the plants are doomed, this is a big failure....
