Cassava is one of the main carbohydrate sources in the tropics, and it has worldwide importance as basic food for millions of persons in America and Africa. This root crop is affected by cassava frog skin disease that in Colombia produces yield losses of almost 90%. A phytoplasma was associated w...

Cassava frogskin disease (CFSD) is an economically important root disease of cassava (Manihot
esculenta) in Colombia and other South American countries, including Brazil, Venezuela, Peru,
Costa Rica, and Panama. The roots of severely affected plants are thin, making them unsuitable
for consumptio...
