Compared with other herbicides, glyphosate has the highest safety

"Is glyphosate safe?" A few days ago, at the Seminar on Agricultural Biotechnology Development and Challenges, Xu Haibin, a researcher at the National Food Risk Assessment Center, said in a report entitled "Glyphosate Safety" that comprehensively follow international standards.
From the recognized procedures and methods, as well as the point of view of international authoritative evaluation agencies, there is currently no evidence that glyphosate is carcinogenic
.
Lin Min, director of the Institute of Biotechnology of the Chinese Academy of Agricultural Sciences, also believes that any herbicide cannot be 100% non-toxic.
Compared with other herbicides, glyphosate has the highest safety
.
Glyphosate market demand is large.
According to reports, glyphosate is the most commonly used broad-spectrum herbicide in global agricultural production.
It has a good long-term safe use record of 40 years and has been used in more than 160 countries in the world.
A total of more than 300 independent toxicology studies have been conducted worldwide
.
In the agricultural market, glyphosate is used in no-till spring rapeseed fields, no-till winter rapeseed fields, and no-tillage seedling throwing rice fields to eliminate weeds in corn or cotton fields before planting and between fruit trees
.
Lin Min believes that the use of glyphosate herbicides can preserve precious topsoil, reduce stream sedimentation, and help maintain soil moisture in a sustainable agricultural system
.
In the industrial market, glyphosate can remove harmful weeds, such as poison ivy and thorn bushes in schools, parks, and entertainment venues, and treat roadside vegetation, reduce emissions during mowing, and eliminate residues after mowing
.
It is reported that glyphosate has been occupying the top position of China's pesticide export varieties in recent years
.
Data show that China is the largest producer of glyphosate.
Glyphosate was China's largest pesticide export in 2016.
The export of glyphosate reached 477,000 tons, accounting for 34.
76% of China's total pesticide exports, or about US$996 million
.
The international authoritative assessment agency affirms the safety of glyphosate.
It is understood that in March 2017, the assessment result of the European Chemicals Agency (ECHA) Risk Assessment Committee (RAC), an authority in the field of chemical regulation, pointed out that the existing science There is insufficient evidence to classify glyphosate as a carcinogen, mutagenic or reproductive toxic substance, and to classify glyphosate as a substance that is non-carcinogenic, non-mutagenic, non-reproductive, non-genotoxic, and non-specific target biological toxicity
.
In April, Health Canada's Pest Management Regulatory Agency (PMRA) approved the application for renewal registration for products containing glyphosate to continue to be sold and used in Canada after completing a comprehensive and multi-year reassessment of glyphosate
.
PMRA released the summary report of its reassessment resolution for glyphosate: Glyphosate is not genetically toxic, and is unlikely to bring cancer risk to humans; the residues of glyphosate in diets (food and drinking water) will not Bring health risks to humans
.
In the following May, the European Food Safety Agency (EFSA), the EU food safety risk assessment agency, publicly stated in a statement that glyphosate was "unlikely to cause carcinogenic hazards to humans" and expressed the results of the ECHA study.
Support
.
In the official statement of the "European Food Safety Agency Glyphosate Evaluation" published by EFSA, EFSA emphasized that the evaluation of glyphosate adopts a comprehensive peer review procedure, which is carried out in accordance with EU regulations on pesticides, and the evaluation process is detailed and comprehensive.
It lasted for 3 full years, involving nearly 100 experts from EFSA and the same authority from member states
.
It is reported that the International Agency for Research on Cancer (IARC) classified glyphosate as a "more likely carcinogen" classification in 2015, which involved glyphosate in the whirlpool of controversy.
However, after the release of the classification, many scientists and researchers around the world Regulators all responded by affirming the safety of glyphosate and pointed out: IARC rating is flawed and its rating is not a scientific research.
It did not include all the literature in the entire rating process, but only partially referred to some of the literature
.
Media reports, including the Joint Conference on Pesticide Residues (JMPR) established by the World Health Organization and the Food and Agriculture Organization of the United Nations, the United States Environmental Protection Agency (EPA), the European Food Safety Agency (EFSA), the German Federal Institute for Risk Assessment (BfR), and Canadian Pest Management Many regulatory agencies, including CPMRA, and the Australian Pesticide and Veterinary Drug Administration (APVMA), have publicly stated that glyphosate is "not likely to cause cancer in humans.
"
.
Glyphosate herbicidal mechanism: How safe is it to act only on plant glyphosate? The scientific name of glyphosate is N-(o-acylmethyl)glycine, which can kill almost all plants.
This kind of herbicide in the industry is called "killing herbicide" or "non-selective herbicide", Institute of Biotechnology, Chinese Academy of Agricultural Sciences Director Lin Min explained, "But this does not mean that glyphosate can kill all living things, it can only kill plants
.
" According to reports, glyphosate enters the plant body mainly through branches and leaves or roots, and then transfers to the plant.
The rest of the plant is eventually discharged into the soil through the root system
.
After entering the soil, glyphosate quickly combines with metal ions such as iron and aluminum and loses its activity.
It has no adverse effects on the seeds and soil microorganisms hidden in the soil
.
In addition, glyphosate salt is easily dissolved in water, which means it is difficult to accumulate in animals and plants
.
According to reports, the glyphosate metabolism experiments conducted by the United States, the European Union and the Food and Agriculture Organization of the United Nations have also proved that after 6 to 7 days of glyphosate entering the plant, there is a residual amount of 0.
05 to 0.
54 mg per kilogram in the body
.
"There are too many things that may cause cancer in our lives.
If you want to exclude all the things that may cause cancer in your life, then you cannot survive
.
" Lin Min believes that chemical products also have green products, and glyphosate is the most typical one.
Of green chemical products
.
"Scientific research shows that glyphosate does not accumulate in animals, and it has no teratogenic, mutagenic, or carcinogenic effects on animals under the test conditions
.
Therefore, glyphosate is classified as a low-toxic pesticide
.
" Lin Min said, any weeding It is impossible to be 100% non-toxic.
Compared with other herbicides with high toxicity and high residue, glyphosate has low toxicity and low residue.
Under the current situation, glyphosate has the highest safety among herbicides
