Description:

 

Paraquat is a non-selective contact herbicide, quaternary nitrogen herbicide.

Paraquat is widely used for road-spectrum control of broad-leaved weeds and grasses. It is a

and by translocation within the plant. It has been employed for killing marijuana in the U.S. and in

Mexico. It is also used as a crop desiccant and defoliant, and as an aquatic herbicide.
