Colletotrichum truncatum is a plant pathogen.[1]

Symptoms

Symptoms appear as dark red to black lesions on the lower surface of the leaves. They appear as sunken lesions surrounded by a raised brown-black border on the pods, petioles and stems. Very small black fruiting bodies of the fungus are usually visible in older lesions.[2]

Other symptoms include shedding of leaves, flower and pod abortion.[2]

Infected seeds appear discoloured with brown or grey staining or dark flecks.[2]

Management

Partners of the CABI-led programme, Plantwise including LUANAR recommend using certified, disease-free seed. If using saved seed, they recommend selecting seeds which are not shrivelled mouldy or discoloured.[2] They also recommend rotating soybean with cereals such as maize and sorghum every 2-3 seasons and remove any diseased crop residue and bury any remaining material.[2]
