Scope of application
It can control various annual weeds; it has a strong killing effect on perennial weeds, but its underground stems and roots can sprout new branches; it has no effect on the brown stems and trunks that have been lignified. It is suitable for the control of weeds in orchards, mulberry gardens, rubber gardens and forest belts. It can also be used to control weeds on non-arable land, ridges and roadsides. For broad-row crops such as corn, sugarcane, soybeans and nurseries, directional spray can be used to prevent and control impurities grass.
It can be used as a late-stage auxiliary agent as a defoliant for machine-harvested crops. Since the crops use defoliants and do not achieve the ideal defoliation effect when the harvesting period is approaching, paraquat can quickly kill the green tissues of the crops and make them dehydrated and dry without affecting the short-term stacking and storage of the harvested fruits after mechanical harvesting. transport. For example, cotton, peppers and other crops are harvested from seed cotton and fruits with low moisture regain. When the moisture regain is high, mildew will occur when stacked in a short time. This requires minimizing fresh leaves and stems when harvesting, and using paraquat to quickly kill green tissues, thereby reducing the moisture regain of seed cotton and peppers, and ensuring that they can be stacked and transported in a short time after machine harvest.
Safety to crops: Paraquat is a biocidal herbicide. If it is not sprayed on the green stems and leaves of the crop, the liquid will only stain the brown lignified bark and branches, which will not harm the crops and trees. Paraquat will lose its activity in contact with soil, and it will be removed 1-2 days before sowing, which is safe for crops.
