Pesticide Contaminants in Water Test Kit, an Innovation from Chula for Safe and Sustainable Agriculture

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.
