Is this a Minor Pest?
Yes
Minor Pest Title
Brown leaf spot (Cercosporidium henningsii)
Minor Pest Description
Symptoms are restricted to older leaves. Brownish round spots with definite borders appear on the upper leaf surface. On the lower leaf surface, they are brownish-grey in colour. Infected leaves later become yellow and eventually drop. In wet areas the disease may cause a yield reduction of up to 20%.
Minor Pest What to do.
- Though the disease is widespread in most cassava growing countries, it is not an economically important disease problem and it does not warrant any intervention.
