Problems solved by technology

But this herbicidal composition still has certain defects: this glyphosate-containing herbicidal composition is only a herbicidal composition of glyphosate and triclopyr, and there is no other form of glyphosate-containing herbicidal composition. Therefore, The type of herbicidal composition is relatively simple

Embodiment 1

[0017] Take by weighing 30 kilograms of glyphosate, 4 kilograms of oxyfluorfen, 2 kilograms of polycarboxylates, 12 kilograms of alkylnaphthalene sulfonates, 1 kilogram of bentonite, and 51 kilograms of methyl oleate; , alkyl naphthalene sulfonate and methyl oleate were added to the reaction kettle and mixed evenly, then bentonite, glyphosate acid and oxyfluorfen were added in turn, and stirred, and sand milled after fully stirring to obtain the main active ingredient An oil suspension containing 30% glyphosate and 4% oxyfluorfen.

Embodiment 2

[0019] Weigh 70 kg of glyphosate ammonium salt, 10 kg of fomesafen, 8 kg of polycarboxylate, 4 kg of oleylamine polyoxyethylene ether, and 8 kg of kaolin, and then fully mix these substances into the airflow Pulverize until the particle size is less than 5 microns, and then granulate with an extrusion granulator to make water-dispersible granules containing 70% glyphosate ammonium salt and 10% fomesafen.

Embodiment 3

[0021] Weigh 33 kg of glyphosate ammonium salt, 8 kg of glufosinate ammonium, 5 kg of propylene glycol methyl ether, 4 kg of ethylene glycol and 20 kg of deionized water, put them into the reaction kettle and stir to raise the temperature to 80 ° C, keep it warm for 1 hour, and cool down to 35°C, then add 8 kg of synergist, and finally, add deionized water to 100 kg to prepare an aqueous solution of 33% glyphosate and 8% glufosinate-ammonium.

Abstract

The invention relates to a weeding compound containing glyphosate. The weeding compound comprises an active ingredient A, an active ingredient B and the balance of pesticide additive, wherein the molar ratio of active ingredient A to active ingredient B is (1-30):(30-1); the total weight of the active ingredient A and the active ingredient B is 33%-86% of the weight of the compound; the active ingredient A is one of glyphosate and glyphosate salt; the active ingredient B is one of glufosinate-ammonium, fomesafen, oxyfluorfen, trichlopyr, 2,4-dichlorphenoxyacetic acid, 3,6-dichloro-2-methoxybenzoic acid, 2-methyl-4-chlorophenoxyacetic acid or the salt thereof. The invention has the advantages that the components of the active ingredients of the weeding compound containing glyphosate are changed so that the weeding compound containing glyphosate is in various forms, the preventing and controlling effect of the combination is obviously better than that of single use, the dosage is reducedand the pesticide cost is reduced.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, and relates to a herbicide, in particular to a herbicide containing [0002] Glyphosate herbicidal composition. Background technique [0003] Chemical weed control is one of the main means of controlling weeds in agriculture. Glyphosate is a systemic, chronic, broad-spectrum herbicide that mainly inhibits enolacetonylshikimide phosphate synthase (EPSP) in plants. Thereby inhibiting the transformation of shikime into phenylalanine, tyrosine and tryptophan, interfering with the synthesis of protein, leading to plant death. Due to its excellent herbicidal activity, broad herbicidal spectrum, low soil residue, long weed control time, and the widespread planting of herbicide-resistant transgenic crops, glyphosate has become the world's No. 1 herbicide in sales Variety. [0004] However, due to the continuous use of glyphosate in large quantities for a long time, the problem of weed resistance ...
