Do prophylactic applications of fungicides work to prevent Late Blight
in tomatoes? How about waiting until the first sign of spotted yellow
leaves and then spraying? Daconil, Captan, Maneb, or Bordeaux mixture?

Planning for next year,

I sprayed my plants with Agway's Fruit Tree Spray, which contains Captan,
after they started to get sick, it arrested the disease and I got a fair
number of tomatoes. I'll look for something safer next year and use it
prophylacticly.

Seem to be lots of tomato problems in the US this year, however Washington
State was pretty good overall.

Cornell put out some info on this year's NE crop conditions that may be
useful to you:
