Paraquat is a non-selective herbicide. However, due to the lack of a specific antidote, the mortality rate after poisoning is high, the death process is long, and patients suffer greatly. There is a strong call for its ban in society. In order to safeguard people's lives and health safety and ensure the safe production and use of paraquat, the Ministry of Agriculture has successively taken relevant measures in recent years to strengthen the agricultural registration, production, sales and use management of paraquat products. Paraquat, with the chemical name 1-1-dimethyl-4-4-bipyridine cationic salt, is a fast-acting non-selective herbicide. It has contact killing effect and certain systemic effect, and can be quickly absorbed by the green tissues of plants, causing them to wither and die. It has no effect on non-green organizations.
