Advantage of the Paraquat

Paraquat has been a valuable tool for farmers all over the world for nearly 50 years. Its speed of action, rainfastness and now its role as a weed resistancefighter are unsurpassed.However, paraquat's importance and benefits go beyond simply weed control. Its unique property of being locked onto soil so tightly on contact, and the consequent biological inactivation, mean that it has become a key component inconservation tillage systems, especiallyno-till.Paraquat plus reduced tillage improves soil structure and fertility, timeliness of operations, biodiversity and the overall profitability of farming. It is also unique as a non-selective herbicide in being able to be sprayed between the rows of growing crops without fear of crop damage.In this section you can find out about the specific benefits paraquat brings on the farm, for theenvironment and in rural communities.
