Thailand is one of the countries where Good Agricultural Practice (GAP) and other production process management methods have been developed. This study analyzes the characteristics of Thailand's national GAP, referred to as QGAP, primarily from the perspective of extension and supporting systems. A case study was conducted in Chantaburi province. Agricultural offices in the province and districts disseminate the knowledge and technology of QGAP and train orchard farmers in collaboration with agricultural cooperatives and various types of farmers' groups. QGAP-certified durian and mangosteen are exported through the packing centers certified with Good Manufacturing Practice certifications. The food chain for these products has been set up to secure food safety. The research concludes that QGAP has functioned effectively in small-scale orchard faming, under the decentralized extension and supporting system.
