Concerns have been raised about the quality of Jeju buckwheat due to the onset of monsoon rains. The Jeju Special Self-Governing Province Agricultural Research and Extension Services has urged farmers to quickly and thoroughly harvest buckwheat not already harvested during the rainy season to prevent quality decline. The monsoon season often overlaps with the harvest period, increasing the risk of 'sub-germination' and delaying seed drying. The services have recommended immediate threshing and drying of harvested buckwheat and advised storing harvested buckwheat from spring as seedlings in cold storage to maintain quality and prevent damage by diseases and pests.
