Abstract

The invention relates to a paddy field herbicide, and in particular relates to a penoxsulam-containing herbicide composition which comprises mixture prepared by effective components penoxsulam A and herbicide B according to the ratio of 1: 1-1: 99, wherein the herbicide B is one selected from butachlor, pretilachlor, mefenacet, bentazone, mesotrione or oxadiargyl. The penoxsulam-containing herbicide composition can be prepared into conventional preparations such as a suspending agent, water dispersible granules, wettable powder, granules, effervescent tablets and the like. The experiments prove that the penoxsulam-containing herbicide composition is reasonable in ratio; the penoxsulam-containing herbicide composition can be used for controlling weeds of a paddy field, is remarkable in weeding effect, wide in weeding spectrum and safe to paddy, and has obvious synergism, thus being an ideal herbicide for controlling the weeds of the paddy field at present.

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...
