Hard surfaces and the glass in greenhouses can be cleaned in the same way. Clean any plant supports and other garden equipment that has previously come into contact with blight with a disinfectant such as Jeyes Fluid before re-use, to make absolutely sure that there is no disease transfer.Infected material should be deeply buried (below the depth of cultivation), consigned to the local council green waste collection or burned, rather than composted (see the 'Biology' section, below).Leaf mould doesn't cause lesions on the stems or extensive fruit decay, however. Visible growth of the leaf mould fungus on the underside of affected leaves is greyish-brown rather than white, but if the leaf tissue has been completely killed this may be difficult to see. Greenhouse-grown tomato plants can also be affected by a different disease called leaf mould, which produces very similar symptoms on the leaves to those of blight. ![]()
