Abstract

The invention discloses a weedicide combination, including the active components in weight percent: 2-(1, 3-benzothiazol-2-oxy) - N - (4 - fluorophenyl ) - N - (1 -methylethyle) acetamide 50-100% and sulfonylurea weedicide 0-50%. The sulfonylurea weedicide selects from: bensulfuron, imazosulfuron, ethoxysulfuron, cyclosulfamuron, azimsulfuron, ethersulfuron, imazosulfuron or chlorazolsulfuron. It can be processed into wettable powder, water dispersible granule, tablet, granule, and suspending agent, able to effectively prevent and eliminate various gramineous weeds, cyperus weeds and broad-leaved weeds in the rice field.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, and in particular relates to the preparation and application of a new herbicidal composition for controlling gramineous weeds and broad-leaved weeds in paddy fields. Background technique [0002] 2-(1,3-Benzothiazole-2oxy)-N-(4-fluorophenyl)-N-(1-methylethyl)acetamide is a new type of oxyacetamide herbicide, The structural formula is as follows: [0003] [0004] Its preparation and application have been disclosed in Chinese invention patent application CN1411719A. The compound has high herbicidal activity against gramineous weeds, has the characteristics of fast action speed, herbicidal activity of soil treatment is obviously higher than that of stem and leaf treatment, and is safe for crops; but the control effect on broad-leaved weeds is poor. In addition, there is no preparation of 2-(1,3-benzothiazole-2oxy)-N-(4-fluorophenyl)-N-(1-methylethyl)acetamide and the herbicidal Bibliograph...
