[0052] Implementation example one:

[0053] Test report on determination of activity of dioxsulam and isoxaflutole on weeds in corn field

[0054] Experiment purpose: To determine the herbicidal effects of xoxsulam and isoxaflutole and their different combinations on target weeds under potted conditions in the greenhouse, and to evaluate their combined effects, for formulation development and pesticide registration. Field efficacy trials provide scientific evidence.

[0055] Test target: crabgrass (D. sanguinalis,).

[0056] Test chemicals: 97% original drug of florasulam and 95% original drug of isoxaflutole, all provided by Shaanxi Meibang Pesticide Co., Ltd.

[0057] Pharmacy configuration:

[0058] Dioxsulam solution: Accurately weigh 0.0039g of 97% dioxsulam technical drug, dissolve it in 0.2mL DMF, add 400mL of clear water containing 0.1% TWEEN80 emulsifier, stir evenly, and prepare 15g ( a.i. / hm 2 ) solution, then diluted with water to 5g (a.i. / hm 2 ), 2g(a.i. / hm ...

Abstract

The invention relates to a weeding composition containing florasulam and isoxaflutole. The weeding composition is mainly characterized by containing 1-60 percent of florasulam with effective components, 1-80 percent of isoxaflutole, addition agent and the balance of other excipients. The weeding composition is prepared into wettable powder, water dispersible granules, suspending agents, microemulsion, aqueous emulsion and the like and can be used for controlling various weeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing florasulam and isoxaflutole, which is used for preventing and controlling weeds in corn fields and wheat fields. Background technique [0002] In 1955, it was reported that Herbicide could increase the control effect of thatch quat on Limegrass. Later, with the further development of herbicide production and application, the mixed use of herbicides gradually developed. my country also pays more attention to the research on the mixed use of herbicides, which is widely regarded as one of the important measures for the rational use of herbicides. A series of herbicide mixtures have been developed and great progress has been made. [0003] Florasulam (florasulam), molecular formula: C 12 h 8 f 3 N 5 o 3 S, chemical name: 2',6'-difluoro-5-ethoxy-8-fluoro[1,2,4]triazol[1,5-c]pyrimidine-2-sulfonanilide. Flusulam is an inhibitor of...
