Abstract

The invention discloses a nanometer dispersible oil suspending agent containing profoxydim and quinclorac and a preparation method and application of the nanometer dispersible oil suspending agent, and relates to the technical field of herbicides. The nanometer dispersible oil suspending agent containing the profoxydim and the quinclorac is prepared from the following components in parts by mass (100 parts in total): 7.5-15 parts of profoxydim, 2.5-5 parts of quinclorac, 0.1-10 part of a nanometer carrier, 1-10 parts of a wetting agent, 1-10 parts of a dispersing agent, 0.1-1 part of a defoaming agent, 7.5-15 parts of a safener, 0.1-1 part of a stabilizer, 1-5 parts of an antifreezing agent, 0.1-5 part of a thickening agent and balance of vegetable oil. According to the invention, the fentrazone-ethyl and the quinclorac are reasonably proportioned, so that the medicinal effect of the herbicide in the paddy field is enhanced, meanwhile, the active ingredients of the pesticide are loadedby the nano-carrier, so that the weeding effect is quick, the lasting period is long, the utilization rate of the pesticide is improved, and the spraying frequency and the dosage are further reduced.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to the technical field of a nanometer dispersible oil suspension containing cycloclozone and quinclorac, its preparation method and application. Background technique [0002] Rice is one of the main food crops in my country, and rice weeding is a major problem in production. Chemical weeding is currently the main means of controlling weeds. In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. At the same time, because weeds occur with complex grass phases and various types, the use of a single species can no longer effectively solve farmland weeds, and all will show a certain aspect of defects. [0003] At present, there are many kinds of herbicides on the market, and at the same time, the application technology is also demanding. If there is a little carelessness in the application, problems such as phytotoxicity ...
