Host: Glycine max, Soybean Disease name: AnthracnosePathogen name: Colletotrichum truncatum
Anthracnose of soybean was first reported from Korea in 1917, but now occurs in all soybean-growing areas. The disease can cause 16 to 100 per cent losses in yield depending upon the cultivar and environmental conditions. The infected pods either have very small, shriveled, brown, moldy seeds or produce no seed. Anthracnose of soybean can be managed by the use of resistant varieties, clean cultivation, and pathogen-free seeds. Fungicide seed treatments provide a highly effective means of improving germination and seedling vigor of seed lots that are infected with Colletotrichum. Foliar fungicide applications are very useful in reducing seed infection by Colletotrichum.
