Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of herbicide, be specifically related to a kind of herbicide containing glyphosate and preparation method thereof.
Background technology
Glyphosate be a kind of high-efficiency low-toxicity bud after steriland herbicide, be the maximum kind of current domestic herbicide yield.The mechanisms of glyphosate is by weeds killer by Uptake and translocation effect, thus humans and animals is nontoxic.It addition, glyphosate is easily degraded by microorganisms after burying, will not contaminated soil and subsoil water, therefore glyphosate be a kind of efficiently, wide spectrum, low toxicity and eco-friendly steriland herbicide.Glyphosate is transmitted to plant parts after being absorbed by stem and leaf, can prevent and kill off unifacial leaf and the plant of the section more than 40 such as dicotyledonous, annual and perennial, draft and shrub.Glyphosate is quickly combined with the metal ion such as ferrum, aluminum after burying and loses activity, and seed hiding in soil and soil microorganism are had no adverse effects.Based on above many merits, glyphosate just obtains the establishing in large scale of wide popularization and application, particularly genetically modified crops once coming out, and more makes the whole world that the demand of glyphosate is constantly increased.
At present, the weeds that the result of use of glyphosate was generally sprayed at about 7 days just start death.Use in Winter-Spring microthermal climate especially, often take 15 to 20 days weeds and just start death.Further, the result of use of glyphosate is strongly dependent upon weather, and it is resistance of rainwater washing against not.Require after the use of glyphosate, within least 8 hours, do not rain, otherwise will dispenser again.Herbicide huge number on market, but harmful, the shortcoming such as toxicity is big, preventive effect is not enough, weeding is not thorough mostly, therefore in the urgent need to developing, a kind of toxicity is little, herbicidal effect good, labile herbicide.
