Cassava Mosaic Disease Impacts Yields in Northern and Northeastern Thailand
A survey by the Thai Tapioca Association indicates that cassava mosaic disease and a shortage of quality planting materials are reducing yields despite an increase in cultivation area.
According to a report from Prachachat Business, the Thai Tapioca Association has released survey results for the 2026/27 production season. The data reveals that while the total area harvested for cassava has expanded across Thailand—particularly in the Northeast, as farmers shift from sugarcane and corn due to attractive market prices—the average yield per rai has declined.
This drop in productivity is primarily attributed to the spread of cassava mosaic disease and a critical shortage of high-quality planting materials. These agricultural challenges are currently impacting farming regions in the North and Northeast of the country.
For residents and those involved in the local agricultural supply chain, this development may signal potential fluctuations in tapioca-related product prices or availability. While the association has identified these factors as the cause of the current yield reduction, the long-term impact on national production volumes remains to be confirmed as the season progresses. Travelers visiting rural areas in these regions may observe the ongoing efforts by local farmers to manage these crop health issues. Further updates from agricultural authorities regarding containment strategies or potential support for affected farmers are expected as the situation develops.
