Cassava Mosaic Virus Alert


Symptoms include a mosaic and discoloration of leaves, plant stunting, and a dramatic decrease in root yield.

Who Am I?

Cassava mosaic virus (CMV) is a viral disease that spreads by whiteflies and the movement of planting materials. CMV is a severe threat to cassava growing regions.

Control Measures

Maintaining a whitefly-free environment is not feasible due to their rapid resistance against insecticides and the spread of diseases from moving infected planting material.

*Names marked in red are considered to be highly poisonous to beneficial insects.

*Names marked in green are considered to be organic and IPM (integrated pest management) compatible.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
