Use

Paraquat is one of the most widely used herbicides in the world, controlling weeds in a huge variety of crops.

Paraquat is only sold to farmers. The product is diluted typically 200 times with water and sprayed on to weed foliage. It only works when in direct contact with photosynthesising green tissue.

Paraquat is a unique herbicide because it is:

  • Broad spectrum
  • Very fast-acting
  • Rainfast
  • Inactivated and immobilised upon contact with soil

When used in accordance with manufacturers’ recommendations, paraquat can deliver safe, effective weed control, generating social and economic benefits, while protecting the land for future generations.

In this section you can find information about crops for which paraquat is an essential production tool and a selection of in-depth articles on agronomy topics important to the contexts in which paraquat is used.
