Cassava green mottle virus (CGMV) is a plant virus in the Secoviridae family. It is caused by Cassava Mosaic Virus (CMV) and is spread mainly by whiteflies that feed on cassava leaves. The virus harms the plant’s ability to grow and produce crops.

Symptoms:
- Green spots or yellow patches on leaves that look painted
- Leaves become distorted and stunted
- The plant may die if the disease is severe

Treatment and prevention:
- There are no pesticides or antibiotics to cure CGMV
- The best way to prevent spread is to control whiteflies
- Use disease-resistant cassava varieties
- Remove infected plants promptly to stop spread
- Rotate crops and avoid planting cassava in the same area repeatedly
- Encourage natural whitefly enemies like ladybugs and lacewings
