Will the herbicide paraquat die? Which weeding effect is better?

Paraquat, whose chemical name is 1- 1- dimethyl -4-4- bipyridine cationic salt, is a quick-acting herbicide with contact killing effect and certain systemic effect. Can be quickly absorbed by the green tissue of plants, making them die. It has no effect on non-green organizations. Quickly combined with soil and passivated, it is ineffective for plant roots, perennial underground stems and perennial roots. Paraquat is extremely toxic to people, and there is no specific antidote, and the mortality rate of oral poisoning is extremely high. At present, it has been banned or severely restricted by more than 20 countries. Since July 1 2065438, China has cancelled the registration and production license of paraquat aqua and stopped production. However, the overseas registration of the parent drug manufacturer Aka was retained, allowing it to be used exclusively for export production, and the domestic sales and use of Aka were stopped on July 1 2065438.

Glyphosate is an effective active chemical component in a variety of herbicides widely used, and its use is strictly regulated in the European Union. Glyphosate is not directly related to genetically modified crops, and non-genetically modified crops should be treated with glyphosate. Glyphosate is a non-selective and residue-free herbicide, which is very effective against perennial rooted weeds and widely used in rubber, mulberry, tea, orchards and sugarcane fields. It mainly inhibits the enolpyruvate shikimic acid synthetase in plants, thus inhibiting the conversion of shikimic acid to phenylalanine, tyrosine and tryptophan, interfering with the synthesis of protein and leading to plant death. Glyphosate is absorbed by stems and leaves and delivered to all parts of plants, which can control more than 40 families of plants such as monocotyledonous and dicotyledonous plants, annual and perennial plants, herbs and shrubs. Glyphosate is quickly combined with metal ions such as iron and aluminum after being buried in soil, which has no adverse effect on seeds hidden in soil and soil microorganisms. Control weeds in apple orchards, peach orchards, vineyards, pear orchards, tea gardens, mulberry orchards and farmland leisure areas, and control annual weeds such as Setaria viridis, Leymus chinensis, Ajuga, Sargassum, Xanthium sibiricum, Chenopodium album, Stellaria stellata, and Swinburnum.
