Q. What benefits does paraquat provide to farmers and others?
A. Paraquat is a valuable herbicide tool in developed and developing countries, benefiting farmers, society, and the environment. When used in accordance with manufacturers’ recommendations, paraquat delivers safe, effective weed control and generates greater social and economic benefits, while protecting the land for future generations. The key benefits of paraquat include:
Economic benefits helping farmers improve the output from their land
- Rapid speed of action with complete control of all green plant tissue within 1-7 days
- Increased yields thanks to the timely removal of weeds which reduces competition for light, water, and nutrients
- Ability to work in all weather conditions. Paraquat is rainfast 15 - 60 minutes after application and its uptake is not dependent on temperature or soil moisture making it particularly well-adapted to tropical agriculture
- Reduces labor requirements like hand-weeding and is highly efficient as a tool for inter-row weeding
- Saves time through its compatibility with other herbicides and fertilizers, enabling several products to be applied in one application
- Ideal partner in Integrated Weed Management
DescriptionA decision support system for crop protection which focuses on long-term prevention or suppression of pest problems with minimum impact on human health, the environment, and non-target organisms. IPM takes into consideration all available pest control techniques and tactics (cultural, mechanical, biological, chemical). IPM emphasizes the growth of healthy crops for better productivity with the least possible disruption to agroecosystems.

- The action of paraquat is restricted to the part of the plant that it contacts and it is not translocated to other parts of the plant.
- Any excess paraquat does not run off
DescriptionThe occurrence of surplus liquid (like rain) which originates up-slope and is collected beyond the ability of the soil to absorb it. The surplus liquid then flows away over the surface to reach the nearest surface water (pond, lake, river).

- Paraquat contributes to the reduction of soil erosion
DescriptionDisplacement of solids (soil, mud, rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement.

This helps to bind and stablize soil
- Paraquat is rapidly adsorbed and deactivated upon soil contact
- It is the ideal herbicide for use in conservation tillage
DescriptionAny 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.

DescriptionAlso known as conservation tillage or zero tillage is a way of growing crops from year to year without disturbing the soil through tillage ie cultivating the soil usually with tractor-drawn implements.
