Early Tomato Blight
Happy New Year to all.
Last year I had early tomato blight in my polytunnel. I know blight travels on the wind and I put this down to diseased potato stems being left on to site.
During the winter months I have sprayed all the inside of the tunnel with disinfectant and intend to water Jeyes fluid on the the soil . My tomatoes are grown in pots which a bury in the ground.
Is there any further precautions I can take?
