Abstract

Cassava mosaic disease (CMD) poses a substantial challenge to the success of cassava cultivation in India, primarily attributed to the Indian cassava mosaic virus (ICMV) and the Sri Lankan cassava mosaic virus (SLCMV). This study
examines the impact of diverse management techniques on diminishing CMD viral load in cassava plants, employing quantitative PCR (qPCR) as the principal measurement instrument. The experiment was conducted in a cassava field, with treatment plots assigned in a randomized block design (RBD). The research evaluated the effectiveness of different nutrient applications and insecticidal treatments. Results indicated that treatments, such as fish oil rosin soap and cassava booster, significantly reduced CMD viral concentrations 14 days post-application. The qPCR results showed a substantial decrease in virus copy numbers following these treatments. The study highlights the importance of integrated disease management strategies for CMD control, demonstrating how these practices can lead to healthier cassava crops, increased yields and sustainable crop protection.
