Problems solved by technology

[0023] Penoxsulam alone has many shortcomings. One is that the herbicidal spectrum is not wide enough, and some weeds cannot be controlled and the germination of unearthed weed seeds cannot be inhibited by single use. Second, the cost of penoxsulam alone is relatively high. High, affecting promotion and use

Embodiment 1

[0047] 2kg penoxsulam, 18kg butachlor, 6kg alkylphenol polyoxyethylene ether sodium sulfate, 6kg nonylphenol polyoxyethylene ether, 3kg epoxidized soybean oil, 4kg fatty alcohol polyoxyethylene ether, 1.5kg carboxylate Methyl cellulose, 2kg ethylene glycol, 0.5kg S-29, 27kg purified water are added to the reaction kettle and fully mixed and stirred, and then the material is injected into a sand mill for grinding. The fineness of the ground material reaches 98% and passes through 325 After the target standard sieve, the material is discharged, and the material is put into a mixing tank and mixed evenly to prepare a 20% penoxsulam·butachlor suspension concentrate.

Embodiment 2

[0049] Purify 2kg penoxsulam, 40kg pretilachlor, 5kg sodium dodecylbenzenesulfonate, 5kg sodium lignosulfonate, 2.5kg propylene glycol, 4kgNNO, 0.5kg xanthan gum, 0.5kgS-29, 40.5kg Add water together into the reaction kettle and mix thoroughly, then inject the material into the sand mill for grinding, the fineness of the ground material reaches 98%, and pass through the 325-mesh standard sieve before discharging, and then put the material into the mixing tank and mix evenly , prepared 42% penoxsulam·pretilachlor suspension concentrate.

Embodiment 3

[0051] 3kg penoxsulam, 21kg butachlor, 8kg sodium dodecylbenzenesulfonate, 8kg calcium lignosulfonate, 2.5kg polytrisiloxane, 6.5kg AEO-20, 15kg white carbon black, 18 Bentonite and 18kg of kaolin were added to the cone mixer together, and the uniformly mixed material was added to the jet mill for crushing, and the fineness reached 98%. Passed through a 325-mesh standard sieve to obtain 24% penoxsulam·butyl Grass amine wettable powder.

Abstract

The invention provides a weed killer composition containing penoxsulam and relates to a paddy field weed killer. The weed killer composition contains a mixture prepared from effective components including the penoxsulam A and a weed killer B at a ratio of (1:1)-(1:99); the weed killer B is selected from one of butachlor, pretilachlor, mefenacet, bentazone, mesotrione and oxadiargyl. The weed killer composition can be prepared into conventional preparations such as a suspending agent, water dispersible granules, wettable powder, granules, effervescent tablets and the like. By virtue of experimental verification, the ratio is reasonable; the weed killer composition is used for preventing and removing weeds of paddy fields; the weeding effect is obvious and the weeding spectrum is wide; the weed killer composition is safe to rice and has an obvious synergic effect; the weed killer composition is a current ideal weed killer which can be used for preventing and removing the weeds of the paddy fields.

Description

[0001] This application is based on a divisional application of a patent application with an application date of August 28, 2009, an application number of 200910091600.2, and an invention title of "herbicide composition containing penoxsulam". technical field [0002] The present invention relates to a paddy field herbicide composition, specifically penoxsulam and butachlor, pretilachlor, mefenamide, bentazone, mesotrione or propargyl oxadiazone Compositions. Background technique [0003] Penoxsulam chemical name: 2-(2,2-difluoroethoxy)-N-(5,8-dimethoxy(1,2,4)triazole-(1,5-C )pyrimidin-2-yl)-6-trifluoromethyl-benzenesulfonamide belongs to triazolopyrimidinesulfonamide herbicides, and its molecular structure is: [0004] [0005] Its mechanism of action is to inhibit the action of acetolactate synthase, and the drug is absorbed through the weed leaves, leaf sheaths or roots, and then transmitted to the meristematic tissue, causing the weeds to stop growing, turn yellow, a...
