Description
Technical field
The present invention relates to a kind of oxadiargyl oil-suspending agent and preparation method thereof, belong to pesticide field.
Background technology
Oxadiargyl (also claim rice think reach) is a kind of diazole ketone bud phase selective herbicide of French Rhone-Poulenc exploitation, prevents and kill off broad leaved weed before being mainly used in seedlings such as paddy rice, potato, sunflower, vegetables, beet, orchard.This product Pesticide Residue is low, so the exploitation of oxadiargyl will produce great economic benefit and social benefit.At present; 80% wetting powder is only arranged by exploitation and use; But this kind product produces a large amount of dust in process pollutes big to surrounding enviroment; Multioperation personnel's health is also unfavorable, so the present invention adopts the wet grinding process exploitation to go out oil-suspending agent, to reduce the pollution of environment and operating personnel's damage.
The main formulation of oxadiargyl is difficult for weighing with wettable powder in the time of in process, can causing dust pollution and use at present.In recent years, the friendly novel pesticide formulation of national requirements development environment develops to water baseization, ultramicronising, no dust and control release type direction.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of consumption that reduces dust pollution, reduces agricultural chemicals, improve oxadiargyl oil-suspending agent of result of use and preparation method thereof.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is:
