Embodiment 1

[0024] Example 1: 15% glyphosate imazethapyr soluble granules

[0025] Weigh an appropriate amount of imazethapyr original drug and sodium hydroxide, and add water to prepare a 50% imazethapyr aqueous solution. Weigh 15g of glyphosate ammonium salt technical material (14g based on glyphosate acid), add 4g of alkyl polyglucoside, 5g of tallow amine polyoxyethylene ether, 2g of 50% imazethapyr aqueous solution, and add ammonium sulfate to 100g. Mix evenly, extrude and granulate to obtain the product.

Embodiment 2

[0026] Example 2: 30% glyphosate imazethapyr soluble granules

[0027] Weigh an appropriate amount of imazethapyr original drug and sodium hydroxide, and add water to prepare a 50% imazethapyr aqueous solution. Weigh 30g of glyphosate ammonium salt technical material (28g based on glyphosate acid), add 3g of castor oil polyoxyethylene ether, 7g of tallow amine polyoxyethylene ether, 4g of 50% imazethapyr aqua, and add ammonium sulfate to 100g. Mix evenly, extrude and granulate to obtain the product.

Embodiment 3

[0028] Example 3: 33% glyphosate imazethapyr soluble granules

[0029] Weigh an appropriate amount of imazethapyr original drug and sodium hydroxide, and add water to prepare a 50% imazethapyr aqueous solution. Weigh 33g of glyphosate ammonium salt technical material (30g based on glyphosate acid), add 3g of castor oil polyoxyethylene ether, 7g of tallow amine polyoxyethylene ether, 6g of 50% imazethapyr aqueous solution, and add ammonium sulfate to 100g. Mix evenly, extrude and granulate to obtain the product.

Abstract

The invention belongs to the field of pesticide herbicide, and particularly relates to a complex herbicide of glyphosate and imazethapyr. The herbicide uses glyphosate herbicide and imazethapyr as the active components, and the mass part ratio of glyphosate herbicide (glyphosate acid) to imazethapyr is (10-15):1. The herbicide serves as a glyphosate resistant transgenic crop herbicide preparation. By means of a herbicide composition, the weed control effect is improved, and the herbicide controlling spectrum is widened. A glyphosate herbicidal compound has an outstanding prevention effect on annual gramineous weeds and part of broadleaf weeds and has a poor prevention effect on perennial weeds and part of broadleaf weeds. By compounding glyphosate and imazethapyr, the prevention effect on broadleaf weeds and part of glyphosate tolerant worst weeds is improved, and therefore the complex herbicide combines the herbicidal activity of glyphosate and imazethapyr; compared with single dosage of glyphosate and imazethapyr, the pesticide consumption is reduced, use cost is reduced, and application and popularization are convenient.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, in particular to a compound herbicide of glyphosate and imazethapyr. Background technique [0002] Glyphosate (glyphosate), also known as Zhen Cao Ning, Roundup (Roundup), etc., its chemical name is: N-(phosphonomethyl) glycine, is an organophosphorus herbicide developed by Monsanto Company of the United States in 1971 . [0003] Glyphosate is currently the most economical systemic non-selective herbicide in the world. It is mainly absorbed through stems and leaves and transmitted to underground parts to inhibit enolacetonylshikisinphosphonate synthase in plants, thereby inhibiting The transformation of shikime into phenylalanine, tyrosine and tryptophan interferes with protein synthesis and leads to the death of weeds. [0004] Due to the excellent characteristics of glyphosate, the development and planting of glyphosate-resistant transgenic crops has grown rapidly in recent years, and glyp...
