Thailand's Central Administrative Court upheld the 2020 ban on paraquat and chlorpyrifos herbicides/insecticides, confirming the measure is lawful for public health and environmental protection. The court ruled the government—not manufacturers like Syngenta—must bear disposal costs. The ban has shown measurable results: paraquat residue in produce dropped to zero, pesticide-related deaths fell 20%+, and harmful chemical imports declined 60+ million kg. Impact is moderate for agricultural SMEs facing compliance changes.
