Abstract

The invention discloses a weedicide composition containing glyphosate, acifluorfen and pyrithiobac-sodium. The weedicide composition contains the active components of glyphosate, acifluorfen and pyrithiobac-sodium, and comprises the following components in percentage by weight: 30-60% of glyphosate, 5-30% of acifluorfen, 0.5-10% of pyrithiobac-sodium and the balance of assistant. The preparation formulation of the weedicide composition can be water and soluble powder (granules). The composition has obvious synergistic action after being complexed, enlarges the weed control spectrum, improves the weeding speed and remarkably reduces the consumption and use frequency of the weedicide, and can be used for controlling weeds in woodlands, noncroplands, citrus orchards and other places as well as some gramineous and broadleaf weeds which are difficult to control.

Description

Technical field: [0001] The invention relates to a pesticide composition and a production method thereof, which are herbicides used in forest lands and use glyphosate, acifluorfen and pyrizachlor as active ingredients and a production method thereof. technical background: [0002] At present, the herbicides used on forest land are mainly herbicides such as glyphosate and Kewuzong. However, glyphosate alone has little effect on some weeds, and the effect on broad-leaved weeds is not ideal; Ke Wuzong is a contact herbicide, which can only kill the above-ground parts of plants, and has no effect on some perennial weeds. Poor, and its own high toxicity, easy to cause poisoning incidents. Therefore, the product of the present invention is a compound product of glyphosate, which not only solves the problems of unsatisfactory single-use effect of glyphosate and insufficient herbicidal spectrum, but also avoids the poor effect and high toxicity of Kewuzong on perennial weeds. ques...
