Cercospora leaf spots is caused by the fungus Cercospora brassicicola. Leafspots vary in colour from pale green to white and generally are bordered by brown tissue. They may be circular or appear angular. Severely affected plants may become defoliated. This disease is not economically important in the East African region.

What to do:

• Use certified disease-free seed and, in case of using own seed, hot water treat the seed.
• Practise proper weed management, particularly, cruciferous weeds such as mustard.
• Remove crop residues from the field after harvest.
