Abstract

The invention belongs to the technical field of pesticide formulation processing and specifically relates to a dimethomorph dispersible oil suspending agent and further discloses a preparation method and application thereof. The oil suspending agent disclosed by the invention is prepared from the raw materials of a dimethomorph original material, a non-ionic surface active agent, an anionic surface active agent, a cosurfactant, an adhesion and absorption enhancer, a stabilizer, an enzyme modifier and a dispersion medium. According to the dispersible oil suspending agent disclosed by the invention, the adhesion and absorption enhancer and the enzyme modifier are added to modify a product based on existing oil suspending agent preparation raw material; added catalase and / or cellulase are beneficial to product formulation polymerization and very good modifying treatment on a suspension dispersing situation; the prepared oil suspending agent has very good suspension performance, furthermore, a release effect of effective ingredients of the oil suspending agent is better, and prevention performance of the oil suspending agent to diseases and pests is better. In addition, according to the oil suspending agent disclosed by the invention, polyglutamic acid is more preferably added as a preparation raw material; suspension performance and pesticide effect playing performance are further improved, and a modifying effect is better.

Description

technical field [0001] The invention belongs to the technical field of pesticide formulation processing, in particular to a dimethomorph dispersible oil suspension, and further discloses its preparation method and application. Background technique [0002] Dimethomorph is a fungicide specific for ovicidal fungi. It is mainly used to prevent downy mildew and late blight on grapes and other fruit trees. It is widely used in vegetable downy mildew, blight, seedling damping-off, Tobacco black shank and other diseases caused by fungi of the flagellate subphylum Oomycetes. Dimethomorph has oil systemic activity and is a highly active, water-insoluble organic compound. Therefore, auxiliary components such as carriers, fillers, emulsifiers and dispersants must be added to prepare various types of pesticide preparations to facilitate field use. For administration, the currently registered dosage forms mainly include wettable powder, suspension concentrate, and water-dispersible gran...
