Glyphosate is not used in combination with paraquat, because glyphosate is a chronic systemic herbicide that can be used for 7 to 10 days after spraying onto weeds. It can be absorbed by weed stems and leaves and transmitted downwards. The strain, up to the root system, kills the underground rhizomes of perennial deep-rooted plants, and can also conduct between different tillers of the same plant, killing tillers or branches that are not exposed to pesticides , and the alfalfa can remove roots, and the effect is very good. It is widely used in production to control annual or perennial grasses and dicotyledonous weeds.
Paraquat, also known as gram-free herbicide , is fast-acting and non-selective. After spraying onto weeds, the green part of the ground will only appear to be withered after a few hours. All will die within ~2 days, the grass killing effect is good, and the speed is very fast.
It is not correct to mix the two in order to pursue the dual effects of quick-acting and scribble removal. Because of the quick-acting nature of paraquat, the weed leaves will soon wither, so that the root-removing effect of glyphosate is not obvious, and the control effect on perennial weeds will be greatly reduced, and the money will be wasted. Therefore, glyphosate cannot be mixed with paraquat. When applying, it is necessary to spray glyphosate for 2 days, and then the herbaceous roots absorb the glyphosate solution and then spray paraquat to achieve the quick-acting and thorough killing effect.
