Across the world, cassava is grown for its edible, starchy tubers. In Asia, cassava has been free from major problems for a long time. But recently, the crop has been threatened by new pests and diseases spreading rapidly. Mealybugs are one of them.

Mealybugs first appeared in Thailand in 2009 and provoked drastic yields reduction in infested fields. Indeed, infested plants have smaller leaves and bunchy tops, and hence they capture less light and grow more slowly. As a result roots will be smaller.

In this video, farmers in Thailand share practical tips to reduce the chance of mealybugs arriving in cassava fields. Special attention is paid to planting time; using healthy planting materials; disinfecting cassava stakes; protecting beneficial insects; and regularly observing the crop.

The video was produced by CIAT and AgroInsight with support from the Department of Agricultural Extension in Thailand. The video is available in English, Burmese, Indonesian, Khmer, Lao, Thai and Vietnamese.
