Farmers in Thailand still largely use chemical herbicides, especially paraquat and atrazine, to control weeds on their farms. According to research by the Office of Agricultural Economics, in 2019, Thailand imported almost 10 million kilograms of paraquat and close to 3.5 million kilograms of atrazine. The residues of these herbicides cause harm to the environment, living creatures, and our health.  

THE CONTAMINATION with agrichemicals in Nong Bua Lamphu remains severe according to the latest analysis by Naresuan University researchers, which found very high concentration of four prominent herbicides in soil, water, vegetables, fish and even in local tap water samples.
