Difference between glyphosate and paraquat
Glyphosate is a broad-spectrum herbicide with internal absorption and transmission, which can basically kill all weeds and roots. it takes 3 to 5 days for glyphosate to take effect, low toxicity and high efficiency. Paraquat is a contact type broad-spectrum herbicide, quick-acting, but can not kill roots, can only kill the stems and leaves above the surface, perennial root weeds are easy to re-grow. It has a certain degree of pollution. Moderate toxicity, but no specific antidote, high fatality rate after poisoning.
Glyphosate is a chronic internal conductive herbicide, which is effective after spraying on weeds for 7 to 10 days. it can be absorbed through the stems and leaves of weeds and transmitted downwards to the roots, thus killing the underground roots of perennial deep-rooted plants. it can also conduct transmission between different tillers of the same plant, killing tillers or branches that are not exposed to pesticides, and cutting grass can remove roots, and the effect is very good. It is widely used to control annual or perennial Gramineae and dicotyledonous weeds in production.
Paraquat, also known as gram without trace, is a contact herbicide with quick effect and non-selectivity. after spraying on weeds, as long as the green part of the ground is exposed to the chemical, it will appear wilt symptoms after a few hours, and all will die within 1-2 days. the killing effect is good, and the speed is very fast.
