ChEBI: An organic cation that consists of 4,4'-bipyridine bearing two N-methyl substituents loctated at the 1- and 1'-positions.
Paraquat is classified as quick-acting and non-selective herbicide, which is one of the most widely used herbicides all over the world. It is widely applied in agriculture to control a exceedingly wide range of annual grasses, broad-leaved weeds and established perennial weeds on contact, which can benefit more than a hundred crops, including cereals, oil seeds, fruit and vegetables, growing in all climates. It can be photochemically decomposed by irradiation of ultraviolet rays in aqueous solutions and is rapidly inactivated by soil. As a chemical weed killer, the outstanding properties of paraquat distinguish itself from other agents applied in plant protection products.
Paraquat is a quaternary ammonium compound with herbicide
properties, as diquat. It is contained in Cekuquat? or
Dipril?. It can cause contact and phototoxic contact dermatitis,
acne, and leukoderma mainly in agricultural workers.
Herbicide, Defoliant, Desiccant: Paraquat is a quaternary nitrogen herbicide widely
used for broadleaf weed control. It is a quick-acting, nonselective
compound, that destroys green plant tissue on
contact 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. It is used in many formulations with
other herbicides, e. g., simazine and diquat. Paraquat dichloride
is registered for the control of weeds and grasses
in agricultural and non-agricultural areas. It is used as a
preplant or pre-emergence herbicide on vegetables, grains,
cotton, grasses, sugarcane, peanuts, potatoes, and on areas
for tree plantation establishment. Paraquat is applied
as a directed spray post-emergence herbicide around fruit
crops, vegetables, trees, vines, grains, soybeans, and sugarcane.
It is used for dormant season applications on clover
and other legumes, and for chemical fallow. It is also used
as a desiccant or harvest aid on cotton, dry beans, soybeans,
potatoes, sunflowers, sugarcane and as a post-harvest desiccant
on tomatoes. It is applied to pine trees to induce
resin soaking. Paraquat dichloride is also used on non-crop
areas such as public airports, electric transformer stations
and around commercial buildings to control weeds. Not
approved for use in EU countries. A U.S. EPA restricted
Use Pesticide (RUP).
