Glyphosate, paraquat, and glufosinate are the three herbicides . Each has its own characteristics and advantages, and the plant protection can almost say a few, but the concise summary and generalization are still rare, worthy of summing up, and easy to memorize.
First, glyphosate
Glyphosate has been used for a long time in production. At present, many weeds such as Xiaofei Peng have developed strong resistance to the drug. The herbicide weeding speed is relatively slow, but its systemic conductivity is very strong, can be transmitted to the underground part through the stems and leaves, can also be transmitted between different branches of the same plant, can kill the weeds, roots deep The underground tissue of the root weeds is very destructive and can reach a depth that cannot be achieved by general agricultural machinery. After glyphosate enters the soil, it quickly loses its activity by binding to metal ions such as iron and aluminum in the soil.
Second, paraquat
Paraquat is a quick-acting contact-killing herbicide that has a strong destructive effect on plant green tissue. The weed leaves begin to suffer discoloration 2 to 3 hours after the drug is applied. The drug has no systemic conduction, and can only damage the drug site, and can not damage the seeds in the roots of the plant and the soil, so the weeds are regenerated after application. Can not penetrate the corked bark. Once in contact with the soil, it is adsorbed and passivated. Paraquat is favored because of its quick effect, resistance to rain erosion, and high cost performance. However, it is highly toxic and harmful to humans and animals. Once poisoned, there is no special antidote.
In China, paraquat has stopped production since July 1, 2014, and it is banned after July 1, 2016. Only two new paraquat products in China are registered, so be sure to pay more attention when purchasing.
Third, glufosinate
Glufosinate is a non-selective contact herbicide and a glutamine synthesis inhibitor with partial systemic action. In a short time after application, the ammonium metabolism in the weeds is disturbed, and the ammonium ion of the cytotoxic agent accumulates in the body. At the same time, photosynthesis is severely inhibited and the herbicidal purpose is achieved. The herbicidal effect is good, the herbicidal spectrum is wide, and the long-lasting effect period is up to one month. It can remove weeds that have strong resistance to paraquat and glyphosate. Does not damage the soil structure and does not damage the roots of the crop. When the drug is combined with the soil, it can be quickly decomposed by soil microorganisms, and the crops are safely sown after 1 day of application. As a new generation of fast-acting herbicides, glufosinate has been highly recognized in production.
