Abstract

The invention discloses a dispersible oil suspended agent containing nicosulfuron, tembotrions and atrazine and a preparation method thereof, and belongs to the technical field of a pesticide. The dispersible oil suspended agent disclosed by the invention comprises nicosulfuron, tembotrions and atrazine; a mass ratio of nicosulfuron to tembotrions to atrazine is (1% to 20%):(1% to 20%):(1% to 50%); total mass percentage content of nicosulfuron, tembotrions and atrazine in the dispersible oil suspended agent is 3% to 90%. Firstly, an emulsifier, a dispersant, nicosulfuron, tembotrions and atrazine are added into a reaction kettle after being ground to a particle size of below 0.01cm, and are uniformly mixed and dispersed; a thickener is added in a high-speed shearing state, the mixture is ground to a particle size of below 5mu m, and then a stabilizer, plant oil and deionized water are added into the reaction kettle together and are uniformly mixed and dispersed to oibtain the dispersible oil suspended agent containing nicosulfuron, tembotrions and atrazine. The dispersible oil suspended agent containing nicosulfuron, tembotrions and atrazine, which is disclosed by the invention, has an obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a dispersible oil suspension containing nicosulfuron, tembotrione and atrazine. The dispersible oil suspension concentrate can be applied to weeding in corn fields. Background technique [0002] Corn is one of the main food crops in my country, and weeding of corn 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. 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...
