Paraquat dichloride is a non-selective herbicide widely used to control weeds in various agricultural and non-agricultural settings. It acts by interfering with photosynthesis in plants, causing rapid desiccation and death. Paraquat is valued for its quick action, effectiveness against a broad spectrum of weeds, and its ability to be used in no-till farming practices.
However, it is highly toxic to humans and animals and poses serious health risks if not handled properly. Due to its toxicity, paraquat is subject to strict regulations and restrictions in many countries, and proper safety precautions must be followed during handling, application, and disposal.
