Colletotrichum sublineolum

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-2 cm and can contain dark brown fungal structures.

[2] 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.

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.
