No use spraying tomatoes

After further investigation I have decided spraying will be of little use even on the unaffected plants as it's washed off by rain and won't protect new, unsprayed growth. If you're interested check out this interesting discussion on use of Dithane etc. I like the plastic rigged up to protect the plants from rain but still get water to the roots! For now it seems the best I can do is remove infected leaves to slow down the spread to the fruit. Unfortunately my fruit is still small and so it may not be enough to get a crop. Until I can give plants some protection I won't be growing tomatoes again. :-(
