Abstract:

Identify the common cassava diseases, their damage symptoms, and know the condi
tions under which they will cause severe losses.
Select sites with dense vegetation, deep loamy soils, and flat or gently sloping land to
grow cassava.
Improve the soils by manuring, mulching, and intercropping to encourage cassava
plants to grow vigorously and offset damage by cassava diseases.
Grow cassava varieties that tolerate the common cassava diseases in your area.
Plant stem cuttings from healthy plants without leaf chlorosis, shoot tip die-back, can
kers, fungus patches, or streaks on the stems.
After root harvest destroy discarded cassava stems and storage roots showing any
symptom of disease.
In the control of cassava mosaic disease, select planting material mainly from stem
branches; avoid the basal and main stem portions as sources of stem cuttings.
Plant cassava mainly at the beginning of the wet season; try and avoid late planting.
