Fulvia fulva (Cooke) Cif. 1954 - (tomato leaf mould)
This fungus is widespread and causes leaf mould on tomato. No other hosts are known. The disease often result in significant yield losses which can exceed 50%.
The symptoms include pale yellow spots and mouldy, olive-green to greyish mycelial growth on the lower leaf surfaces. The lesions enlarge, join and infected leaves eventually wilt and die. For management, excessive humidity should be avoided in greenhouses. Resistant cultivars are important. However, new races often appear which overcome such resistance.
