Anthracnose Tetrazolium Chloride Vigor Cold Germ Other common names Ascochyta blight, Mycoshaerella blight, leaf and pod spot, etc. Ascochyta attacks peas, lentils and beans. Appearance Spotting and lesions occur on the leaves, pods, seeds and sometimes the stems. Leaf spots are white to purplish in colour, with indefinite margins and round to irregular shape.
Lesions have a brown margin.
The stem lesions are long and purple. These are the fruiting bodies of the disease. The lesions reduce yield by weakening the plant. If the disease hits early, the flowers will drop off before pods can be produced, further reducing the yield. The disease is carried on the seed or infected stubble.
