Diseases of crops: Tuber - SS2 Agriculture Lesson Note

Cassava Mosaic Virus:

Cassava mosaic virus is a major threat to cassava plants, which are a staple food in many tropical regions.

This virus causes characteristic mosaic-like patterns on cassava leaves, stunting plant growth and reducing root yields. Infected cassava plants become weaker and less productive, posing a threat to food security.

Bacterial Blight (Tuber):

Bacterial blight is a disease that affects various tuber crops, including potatoes. It is caused by bacteria like Xanthomonas spp., which enter plants through wounds or natural openings.

Symptoms include dark, water-soaked lesions on tubers, making them unmarketable. Bacterial blight can lead to reduced crop yields and economic losses for farmers.
