They are endophytic on Euphorbia hirta with another plant pathogen Uromyces euphorbiae (in the Pucciniaceae family and Pucciniales order).[2]
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.[3]
Other symptoms include shedding of leaves, flower and pod abortion.[3]
Infected seeds appear discoloured with brown or grey staining or dark flecks.[3]
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 shriveled mouldy or discoloured.[3] 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.[3]
