Synergistic weeding composition containing glyphosate

Abstract

The invention relates to a synergistic weeding composition containing glyphosate. The synergistic weeding composition is prepared from active components A and B, wherein the component A is selected from glyphosate; the component B is selected from one of traloxydim or methyl traloxydim; the ratio of in parts by mass of the component A to the component B is (300 to 1) to (1 to 1); the composition is also prepared from pesticide additives; the composition is prepared from 1-80% by mass of active components and the balance of the pesticide additives. The preparation of the composition is selectedfrom one of water suspensions, dispersible oil suspensions, water dispersible granules and wettable powder; the composition can be used for controlling and removing weeds in uncultivated land, orchards and vineyards and can also be used for controlling and removing the glyphosate-resistant weeds in corn fields, wheat fields and sorghum fields.

Description

technical field [0001] The present invention belongs to the field of synergistic herbicidal compositions, and specifically relates to a synergistic herbicidal composition containing active ingredients A and B; wherein A is selected from glyphosate, and B is selected from one of quinatrione or methyl quinazodone . Background technique [0002] Glyphosate is known and belongs to the organophosphorus systemic conduction type herbicide. It is mainly absorbed through the stems and leaves of weeds, and then transmitted to the whole plant and roots, interfering with and inhibiting the synthesis of amino acids, thereby causing the weeds to die. Glyphosate can quickly decompose and become invalid in the soil, so it has no residual effect. Glyphosate takes a long time to act. Generally, the weeds gradually turn yellow after spraying, and it takes 10-15 days for the weeds to completely turn yellow and die. According to reports ("World Pesticides", Vol. 36, No. 5, October 2014, Wu Xia...

AI Technical Summary

Problems solved by technology

[0004] Farmland weeds are complex and diverse, and the application of chemical agents is one of the most effective chemical means to control agricultural weeds; it is a good solution to control agricultural weeds with new pesticides without cross-resistance; however, the current development A new pesticide needs to screen tens of thousands of compounds, costing 120-150 million US dollars, and the development cycle is 5-10 years, it is difficult to catch up with the speed of weed resistance; other methods such as crop layout adjustment, different pesticide rotation, etc. , in the actual operation process, it is difficult to achieve obvious effects

[0005] Reasonable chemical herbicide compounding or mixing can expand the herbicidal spectrum, improve the control effect, prolong the application period, reduce the dosage, reduce the risk of phytotoxicity, reduce the residue, and delay the occurrence and development of weed resistance and resistance Therefore, selecting the appropriate herbicide compound or mixture is one of the most effective and economical methods to solve the above problems; however, because the mechanism of action between pesticide mixtures is complex, whether the combination is synergistic is affected by many factors The impact can only be verified by relying on experimental results, and cannot be expected
