Colletotrichum sublineola (wrongly named for many years as Colletotrichum sublineolum)[1], is the causal agent of sorghum anthracnose, which is one of the most important diseases in sorghum and can cause losses up to 25%.

Symptoms

Symptoms appear as small circular red/orange lesions with distinct margins on the upper portion of the stalks, leaves and seeds. The lesions can measure 2mm-2cm and can contain dark brown fungal structures. Brown sunken areas can also appear on the stems.[2]

Management

Partners of the CABI-led programme, Plantwise recommend several methods for preventing spread of C. sublineolum, these include; planting two weeks after onset of rains, planting resistant varieties/hybrids and using certified seed from known seed dealers.[2][3]

Crop rotation with other crops including soybean, groundnuts, cowpea and chickpeas can be used to prevent disease spread.[2][3]

The disease can also be controlled by removing or burying crop residues after harvest. It is also recommended by Plantwise partners, including the National Agriculture Research Organization in Uganda to remove alternate hosts such as Johnson grass and any volunteer sorghum plants in the field.[3]
