Paraquat
Paraquat
Paraquat (pronounced: /ˈpærəkwɒt/) is a highly toxic herbicide (chemical substance used to control, deter, or destroy plants) that is widely used in agriculture. It is known for its fast action and non-selective nature, meaning it kills most green plant tissue on contact.
Etymology
The term "paraquat" is derived from the chemical name paraquat dichloride, which is a compound of the quaternary ammonium class. The name "paraquat" is a blend of the words "para" and "quat", referring to the para position of the quaternary nitrogen.
Usage
Paraquat is used to control weeds in more than 100 crops, including fruits, vegetables, and grains. It is also used in the cultivation of cotton, coffee, palm oil, and rubber. Despite its toxicity, paraquat is favored for its efficiency and speed.
Health Effects
Exposure to paraquat can lead to serious health effects, including lung damage, heart failure, and kidney failure. Ingestion or inhalation of paraquat can be fatal. There is no known antidote for paraquat poisoning.
