What is the difference between glyphosate and paraquat?

1. Glyphosate is a systemic and conductive broad-spectrum herbicide, which can basically kill all weeds, and can not only kill the above-ground parts of weeds but also kill their roots; But it takes a long time to take effect. Low toxicity, high efficiency, no pollution, new environmental protection.

2. Paraquat is a contact-killing broad-spectrum herbicide, which can kill almost green weeds with quick effect, but it can't kill the roots, only the stems and leaves above the surface, and perennial weeds are easy to grow again. There is a certain degree of pollution.

1. glyphosate, other names: Zhencaoning, Roundup, glyphosate and phosphonomethyl are herbicides developed by Monsanto Company in the United States.

scientific name N- (phosphonomethyl) glycine, N- (phosphonomethyl) aminoacetic acid, is an organophosphorus herbicide.

glyphosate is a low toxic herbicide. The acute oral LD5 of the raw powder in rats is 43mg/kg, and the acute percutaneous LD5 in rabbits is more than 5mg/kg. It has mild irritation to rabbit eyes and skin, and has no allergic and irritating effect on guinea pig skin. Glyphosate does not accumulate in animals. No teratogenic, mutagenic and carcinogenic effects were observed on animals under the experimental conditions. Low toxicity to fish and aquatic organisms; Non-toxic to bees and birds; Safe for natural enemies and beneficial organisms. The pure product is a white solid, and its solubility in water is 1.2% (at 25 degrees Celsius). Low toxicity to people and animals. The acute oral LD5 of rats is 432 mg/kg, and the percutaneous LD5 of rabbits is more than 794 mg/kg. Low toxicity to fish.

history: the herbicidal property of glyphosate was discovered by American D.D. Baird in 1971, developed and produced by Monsanto, and has become an important herbicide in the world in 198s.

2. Herbicidal characteristics of paraquat: paraquat is a non-selective contact herbicide, which can kill most gramineous and broad-leaved weeds.

weeding mechanism: paraquat can be quickly absorbed by the green tissues of plants, producing peroxides in plants, which has a strong destructive effect on the green tissues of plants, stopping photosynthesis and chlorophyll synthesis quickly and making them die, thus achieving the weeding effect.

main ingredients: the preparation is composed of effective ingredients, wetting agent, dye and emetic *

Function characteristics: non-selective quick-acting contact-killing herbicide

Usage: directional spraying

Appearance: dark blue-green water-soluble liquid

Stability: stable under acidic and neutral conditions, hydrolyzable by alkali and decomposed by ultraviolet rays.
