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 resistanceDescription The inherited ability of a plant/weed to survive a dose of a herbicide normally lethal to that species.

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 in conservation tillageDescription Any tillage and planting system that covers 30 percent or more of the soil surface with crop residue after planting to reduce soil erosion by water.

Paraquat plus reduced tillage improves soil structure and fertility, timeliness of operations, biodiversityDescription The variety of life in all its forms, levels and combinations.
