Embodiment 1

[0053] Embodiment 1: emulsifiable concentrate

[0054] Make up 2% pyriflubac, 3% saflufenacil, 15% cyhalofop-ethyl, 6% fatty alcohol polyoxyethylene ether, 4% alkylbenzene sulfonate, and heavy aromatic hydrocarbon solvent oil to 100%, after mixing Stir and process to obtain an emulsifiable concentrate preparation. According to actual needs, an appropriate amount of xylene can be added to make an emulsifiable concentrate preparation with an active ingredient content of 20%.

Embodiment 2

[0055] Embodiment 2: water dispersible granules

[0056] 3% pyrifluzan, 3% saflufenacil, 15% cyhalofop-methyl, 5.0% polymer polycarboxylate, 2.0% acyl glutamate, 15.0% sodium chloride, 2.0% white carbon black, 55.0% of kaolin is fully mixed, then crushed by airflow, and granulated to obtain water-dispersible granules. The water-dispersible granules contain 21% active compound, and the particle size of the product is 80-120 mesh.

Embodiment 3

[0057] Embodiment 3: dry suspension

[0058] 9% pyriflubac, 15% saflufenacil, 30% cyhalofop-methyl, lignosulfonate 8.0%, alkylnaphthalene sulfonate 5.0%, xanthan gum 0.1%, white carbon black 15.0%, kaolin 17.9% fully mixed, then add a certain proportion of tap water, put it into a high-shear homogeneous emulsification kettle for high-speed shear coarse grinding and homogenization, and then pump it to a sand mill for sanding, sanding to a certain particle size, and reprocessing The granules are formed into a dry suspension. The dry suspension contains 54% active compound.

Abstract

The invention relates to an herbicide, in particular to an herbicide composition containing pyriminobac methyl, pyribenzoxim and cyhalofop-butyl, a preparation and an appliance thereof. The herbicide composition containing the pyriminobac methyl, the pyribenzoxim and the cyhalofop-butyl comprises three effective components which are the pyriminobac methyl, the pyribenzoxim and the cyhalofop-butyl, wherein the quality radio of the pyriminobac methyl, the pyribenzoxim and the cyhalofop-butyl is 0.1-60:0.1-60:0.1-70. The pyriminobac methyl, the pyribenzoxim and the cyhalofop-butyl do not have cross resistance, can effectively enhance weeding effect of the herbicide by being mixed and matched, enlarge control spectrums of the herbicide, widely kill various weeds containing graminaceous, cyperaceae and broad leaves, improve fast-acting property and durable effect, reduce times for spraying in a growth period, and have greatly important significance for delaying drug resistance. Simultaneously, because the working concentration of single insecticide reduces, the occurrence risk of pesticide hazard is greatly reduced. The herbicide composition containing pyriminobac methyl, pyribenzoxim and cyhalofop-butyl, the preparation and the appliance thereof meet the demands that a drug is used for many times in agricultural production, the use times of the drug are reduced and the risk of the pesticide hazard is reduced.

Description

technical field [0001] The invention relates to a herbicide, in particular to a herbicidal composition containing pyrifluben, saflufenacil and cyhalofop-fop and its preparation and application. Background technique [0002] Herbicide varieties containing a single active ingredient often have varying degrees of defects in the control of weeds in agricultural fields. For example, weeds are prone to resistance after continuous application, the herbicide spectrum is narrow, and frequent applications will aggravate environmental pollution. One way to control agriculturally resistant weeds is to introduce new ingredients that are not cross-resistant with existing varieties. However, the development cost of new active ingredients is high, the development cycle is long, and it will never keep up with the speed of weed resistance. Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation. Comb...
