Problems solved by technology

This highly resistant biological weed has a similar appearance to common barnyard barnyardgrass, but different in nature. It is still the same grass for farmers, but this resistant biological weed is treated with commonly used barnicides such as two However, quinclorac, bispyribac, and penoxsulam are difficult to achieve the purpose of control. Generally, they will still develop into a strong community, competing with rice for water and fertilizer. When the density is high, it will seriously affect the growth of rice, causing rice to varying degrees. Production reduction threatens the stability and development of rice production in my country

Embodiment 1

[0029] Penoxsulam 2%, Fluroxypyr isooctyl 8%, Fenoxam 6%, Calcium Dodecyl Benzene Sulfonate 5%, Castor Oil Ethoxylate 5%, Polyoxyethylene Polyoxypropylene block copolymer 2%, silicone defoamer 0.2%, organic bentonite 2%, soybean oil balance. Mix all the above-mentioned ingredients evenly according to the stated ratio, and grind them with a horizontal sand mill so that the average particle size of the obtained material is less than 5 microns, and then you can prepare 16% pentafluoro-chlorofluoro-oxazolam dispersible oil suspension concentrate (2:8:6).

Embodiment 2

[0031] Penoxsulam 1%, fluroxypyr isooctyl 9%, fenpyrrole 7%, calcium dodecylbenzenesulfonate 7%, styrylphenol polyoxyethylene ether 3%, castor Sesame oil polyoxyethylene ether 6%, polytrisiloxane 2%, methyl oleate 1%, aromatic hydrocarbon S-150 solvent naphtha balance. Mix all the above-mentioned ingredients uniformly according to the stated proportions, and then 17% pentafluorochlorofluoromethoxazone emulsifiable concentrate (1:9:7) can be prepared.

Embodiment 3

[0033]Penoxsulam 1.5%, Fluroxypyr isooctyl 7.5%, Mefenacet 7%, Calcium dodecylbenzenesulfonate 5%, Castor oil polyoxyethylene ether 6%, Polyoxyethylene Polyoxypropylene block copolymer 3%, xanthan gum 1%, S-150 solvent 15%, water balance. Mix penoxsulam, fenoxazone, polyoxyethylene polyoxypropylene block copolymer and water evenly in proportion, and grind the obtained material with a horizontal sand mill so that the average particle size of the obtained material is less than 3-5 microns. Isooctyl fluroxypyr, calcium dodecylbenzenesulfonate, castor oil polyoxyethylene ether, and S-150 solvent are mixed evenly in proportion, and then added to penoxsulam and fenoxafelazed ointment liquid 16% pentafluoro-chlorofluoro-oxazone suspoemulsion (1.5:7.5:7) can be obtained after adding xanthan gum at the end.

Abstract

The invention discloses a rice field weeding composition with penoxsulam, fluroxypyr-mepthyl and metamifop. The rice field weeding composition comprises the penoxsulam, the fluroxypyr-mepthyl and the metamifop, and the weight ratio of the penoxsulam, the fluroxypyr-mepthyl to the metamifop is (1-2): (4-12): (5-10). The rice field weeding composition has good control effect on weeds such as eragrostis japonica and resistant biotype alkali barnyard grass, weeding performance of the rice field weeding composition is improved as compared with three single agents or a composition of any two in the single agents, pesticide consumption is reduced, environmental pollution is relieved, pesticide resistance of the weeds is delayed, and the rice field weeding composition has good safety for rice and is an excellent novel pesticide composition for preventing and treating the rice field weeds.

Description

technical field [0001] The invention belongs to the field of chemical pesticides, and in particular relates to a paddy field herbicide composition containing penoxsulam, fluroxypyr isooctyl and fenoxen. Background technique [0002] Penoxsulam, chemical name 2-(2,2-difluoroethoxy)-N-(5,8-dimethoxy(1,2,4)triazole-(1,5-C ) pyrimidin-2-yl)-6-trifluoromethyl-benzenesulfonamide. It is a herbicide for post-emergence paddy fields developed by Dow AgroSciences. It was officially registered with the US EPA on September 24, 2004. It was promoted and applied in the southern rice fields of the United States in 2005, and it was registered in my country in 2008. It is a conductive strong acetolactate synthase inhibitor. The drug is absorbed by the stems, leaves, buds and roots, and then transmitted to the meristematic tissue through the xylem and phloem, inhibiting plant growth, making the growing point chlorotic, and weeds for 7-15 days Gradually die. It can effectively control barny...
