Embodiment 1

[0052] Embodiment 1: emulsifiable concentrate

[0053] Mix 5g of pyriflufen, 5g of fenfluramide, 10g of cyhalofop-methyl, 6g of fatty alcohol polyoxyethylene ether, 4g of phenethylphenol polyoxyethylene ether, 5g of N,N-dimethylacetamide, and heavy aromatic solvent The oil is added to 100g, and through mixing and stirring processing, an emulsifiable concentrate preparation is obtained. 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

[0054] Embodiment 2: water dispersible granules

[0055] Mix 8g of pyriflufen, 8g of oxaflufide, 15g of cyhalofop-methyl, 6.0g of polymer polycarboxylate, 3.0g of acylglutamate, 17.0g of sodium chloride, 3.0g of white carbon black, 40.0g of kaolin g fully mixed, then pulverized by airflow, and granulated to obtain water-dispersible granules. The water-dispersible granules contain 31% active compound, and the particle size of the product is 80-120 mesh.

Embodiment 3

[0056] Embodiment 3: dry suspension

[0057] 5g of pyrifluzal, 15g of fenpyramid, 30g of cyhalofop-methyl, 8.0g of lignosulfonate, 6.0g of alkyl naphthalenesulfonate, 0.1g of xanthan gum, 16.0g of white carbon black, 19.9g Mix kaolin thoroughly, add a certain proportion of tap water, put it into a high-shear homogeneous emulsification kettle for high-speed shearing and rough grinding and homogenization, and then pump it to a sand mill for sanding, sanding to a certain particle size, and then granulating Formed into a dry suspension. The dry suspension contains 50% active compound.

Abstract

The present invention relates to a pesticide activity weeding agent composition, more particularly to a weeding synergistic composition containing metamifop, cyhalofop-butyl and pyriminobac-methyl, a preparation and applications thereof, wherein the weeding synergistic composition is characterized by comprising three effective components such as metamifop, cyhalofop-butyl and pyriminobac-methyl, and a weight ratio of metamifop to cyhalofop-butyl to pyriminobac-methyl is (0.1-70):(0.1-70):(0.1-60). According to the present invention, the three compounds do not have cross-resistance, and can provide significant synergistic effects for prevention and control of rice field weeds after the three compounds are mixed, such that the prevention and control spectrum is expanded, various poaceae weeds including echinochloa crusgalli, leptochloachinensis(l.) nees and digitaria sanguinalis (l.) scop, partial broadleaf grasses, and cyperaceae weeds can be widely killed, the quick effect and the lasting-action characteristic are perfected, the number of the times of the medication during the growth stage can be reduced, and the important significance is provided for the delaying of the generation of drug resistance.

Description

technical field [0001] The present invention relates to a pesticide active herbicide composition, in particular to a composition containing fenpyramid, cyhalofop-methyl and pyriflufen, as well as its preparation and application. Background technique [0002] Weed control in paddy fields is the key to a good rice harvest. Rice is one of the main food crops in my country, and weeding in paddy fields is a major problem in production. Chemical weed control is the main means of controlling weeds. In recent years, the rice stem and leaf treatment agents for controlling grass weeds in paddy fields are mainly single-compound preparations with penoxsulam as the core, followed by single-compound preparations of quinclorac and fenoxen. Compound preparations, bispyribac, etc. However, herbicides containing a single active ingredient often have different degrees of defects in the control of weeds in agricultural fields, such as poor effects on malignant weeds such as resistant barnyard...
