Claviceps sorghi

Claviceps sorghi is a species of fungus that infects sorghum plants. It belongs to the genus Claviceps, which includes various fungi known for causing plant diseases. C. sorghi specifically targets sorghum, a widely cultivated cereal crop known for its resilience in arid regions.

Description

C. sorghi infects sorghum plants by producing fungal structures called sclerotia, which replace the seeds of the host plant. These sclerotia are dark in color and contain fungal spores that can spread to other sorghum plants, leading to further infections.

Symptoms

Infected sorghum plants typically exhibit symptoms such as stunted growth, discoloration of the seeds, and reduced yield. In severe cases, the entire seed head of the sorghum plant may be replaced by the sclerotia produced by C. sorghi.

Management

To control C. sorghi infections, farmers are advised to practice crop rotation, use disease-resistant sorghum varieties, and employ proper sanitation measures to prevent the spread of the fungus. Fungicidal treatments may also be applied to reduce the impact of the disease on sorghum crops.

Importance

C. sorghi poses a significant threat to sorghum production, as infections can lead to substantial yield losses. In regions where sorghum is a staple food crop, such as parts of Africa and Asia, the presence of C. sorghi can have detrimental effects on food security and agricultural livelihoods.
