Vegetables need a herbicide up to the challenge

Vegetables on their way to marketParaquat has an important role to play in vegetable cropping because its unique characteristics are particularly suited to the challenges posed by controlling weeds in these diverse crops. Some vegetables are grown on a field scale, many are grown in greenhouses, while the majority are grown by smallholders and in gardens. Vegetable growers face many challenges, including erosion and leaching

of pesticides from highly irrigated light soils; soil compaction from intensive cultivations; and the pressure to multi-crop and harvest early to achieve profitability.

Paraquat is the only herbicide up to facing all these challenges. Its many benefits for vegetable growers come from its very fast, non-systemic action and the fact that it is deactivated and extremely tightly bound on contact with soil, meaning no residual effect and no leaching. Paraquat can be used before sowing or transplanting, and for inter-row weed control. Managing weeds with paraquat keeps them from competing with the crop, yet allows them to re-establish after a few weeks, anchoring the soil and also providing habitats for beneficial insects and other predators of potential crop pests. Using paraquat for weed control allows the adoption of minimal tillage systems which do not rely on controlling weeds by burial from plowing. This saves cash, time and fuel, improves soil structure, reduces erosion and provides havens for wildlife. Growers aiming for early harvests often have to plant early in potentially unfavourable weather conditions. Paraquat gives complete control of weeds within a day or two even in cold weather, and within hours in hot sunny weather. This also allows a fast turnaround time between crops.  In showery weather, paraquat needs only 15-30 minutes before rain to give maximum levels of weed control, compared to glyphosate’s need for several rain-free hours.
