preparation example Construction

[0040] The preparation method of the dispersible oil suspension comprises the following steps: according to the formula, first add an oil phase carrier, an emulsifier, and use a dispersing sand mill to cut for 3-5 minutes; then add dinotefuran and a thickener, Continue to cut for 5-10 minutes; transfer to a sand mill for sanding, and sand for 1-3 hours to obtain a dispersible oil suspension.

[0041] The second aspect of the present application provides the application of the dispersible oil suspension concentrate in controlling pests in wheat, rice, cotton, vegetables and fruit trees.

[0042] As a preferred embodiment, the pests include aphids, leafhoppers, planthoppers, thrips, and powdery mildew.

[0043] The dispersible oil suspension concentrate described in this application uses soybean oil as the oil phase carrier, and is assisted by fumed white carbon black, modified organic soil, and emulsifier. It has good target affinity with wheat and is more conducive to the exer...

Abstract

The invention belongs to the technical field of pesticide preparation processing, and in particular, relates to a dinotefuran dispersible oil suspending agent and an application thereof. The dinotefuran dispersible oil suspending agent provided by the invention is composed of the following raw materials in percentage by weight: 16 to 22 percent of dinotefuran, 12 to 18 percent of an emulsifier, 1.5 to 2.5 percent of a thickening agent and the balance being an oily carrier. The dispersible oil suspending agent disclosed by the invention takes soybean oil as an oil phase carrier and is assistedby fumed silica, modified organic soil and an emulsifier, so that the dispersible oil suspending agent has good target affinity with wheat and is more beneficial to exertion of pesticide effect. The prepared dispersible oil suspending agent has good stability and wide market prospect.

Description

technical field [0001] The application belongs to the technical field of pesticide preparation processing, and in particular relates to a dinotefuran dispersible oil suspension and its application. Background technique [0002] Dinotefuran is a third-generation neonicotinoid insecticide, which can be quickly absorbed by plants and widely distributed in crops by acting on the insect neurotransmitter system and having contact and stomach poisoning effects. Dinotefuran is an agonist of nicotinic acetylcholine receptors that affects synapses in the central nervous system of insects. [0003] Dinotefuran belongs to a class of poorly soluble active ingredients. It is not easy to dissolve in polar solvents such as water. The solubility in water at 25°C is only 40g / L, and it is not easy to dissolve in small and medium polar solvents. For insoluble active ingredients, the smaller the particle size in the formulation, the more dispersed particles, the larger the surface area, and the...
