The Department of Agricultural Extension in Chanthaburi province is investigating the cause of a significant drop in longan prices to 6 baht per kilogram. The price drop is due to the purchase of small and unattractive longan fruits, which are usually left in the garden. The Department has found that about 83.19% of the longan produce has been harvested, leaving approximately 16.81% still in the gardens. To assist farmers, the department is promoting direct sales to consumers, processing of inferior produce, and cultivation of other crops in longan gardens. The COVID-19 pandemic has also led to a labor shortage, affecting harvesting.
