Mixed weed killing agent with glyphosate and diguat dibromide

Abstract

The invention relates to a mixed weed killing agent with glyphosate and diguat dibromide. The mixed weed killing agent is compounded by the following raw materials by weight percent: 1-99.99% of glyphosate and 0.01-99% of diguat dibromide. The mixed weed killing agent is compounded by screening the diguat dibromide and the glyphosate; the diguat dibromide has the contact-poisoning action, but the contact-poisoning action can not hinder the absorption of the glyphosate by leaves, not only is the effect of the glyphosate not influenced, but also the synergistic effect is achieved for the effect of the glyphosate, the weed killing time can be shortened for 3-10 days, and the cost of the pesticides is reduced by 10%, so that the mixed weed killing agent has the characteristics of economy and high efficiency.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a mixed herbicide of glyphosate and diquat. Background technique [0002] Glyphosate is a systemic broad-spectrum herbicide. The main mechanism of action is to inhibit the synthesis of shikimic acid in plants, thereby inhibiting the synthesis of aromatic ring amino acids to achieve the herbicidal effect. Currently, glyphosate is the most widely used herbicide on the market. Typically glyphosate is applied by spraying on plant leaves. There have been a large number of patents to increase the absorption and weed control effect of glyphosate by adding surfactants. The effect of glyphosate application usually starts to die after about 7 days after being sprayed. Especially in the low temperature weather in winter and spring, it often takes 15 to 20 days for weeds to start to die. Moreover, the effect of glyphosate strongly depends on the weather, and it is not resistant to ra...

Problems solved by technology

In order to solve the above problems, the Chinese patent discloses a composition containing glyphosate and paraquat (patent number: 99115217.4), which mainly involves the mixed formulation of two herbicides glyphosate and paraquat, but in fact the pesticide The combination of paraquat and glyphosate is not successful, and the compound preparation of glyphosate and paraquat has long been abandoned in the market
