Cassava mosaic disease: strategies for recovery and sustainable management

Abstract

Cassava is a vital starch food for the global population, primarily cultivated by smallholder farmers on less than one hectare of land. Cassava mosaic disease (CMD) poses a potential threat, causing yield losses of 50–70 per cent. Various causal agents of CMD have been identified in different regions. To curb CMD menace, farmers and researchers employ strategies such as using disease-free planting materials, resistant varieties, nutrient management, and integrated pest and disease management practices. In India, the threat of CMD in cassava production is increasing. This article reviews the past studies on CMD, including its symptoms, yield losses, spread, nutritional management, and control, to provide a comprehensive understanding of the disease and its management.
