Aqueous solution of pyrimethanil

Abstract

The invention relates to a pyrimethanil aqua, which comprises pyrimethanil, acid and water as preparation raw materials, wherein under the auxiliary action of the acid, the pyrimethanil can be dissolved in the water completely to obtain an aqua. Compared with the prior art, the pyrimethanil aqua uses the aqua to replace missible oil, wettable powder and suspending agent, and does not use an organic solvent and cause dust pollution so that pollutant stains are not remained on the surfaces of fruits and vegetables, and drug injuries are not easy to happen.

Description

technical field [0001] The invention relates to a pyrimethanil preparation, in particular to a pyrimethanil aqueous solution. Background technique [0002] Pyrimethanil is a new type of fungicide, which belongs to the anilinopyrimidine class. It has a novel structure and a unique mechanism of action. It reduces the level of certain hydrolytic enzymes related to parasitic tissue necrosis caused by pathogenic bacteria by inhibiting the protein secretion of pathogenic bacteria. Pyrimethanil has systemic conduction and fumigation effects at the same time. After application, it can quickly reach the places where sprays cannot reach, such as flowers and young fruits, to kill germs, and the drug effect is fast and stable. The efficacy of pyrimethanil is not sensitive to temperature. Its protective and therapeutic effects are equally good when applied at relatively low temperatures. It can prevent gray mold of cucumber, gray mold of tomato, gray mold of strawberry, pea gray mold, B...

Problems solved by technology

However, since pyrimethanil wettable powder and suspending agent are prepared as suspensions during use, there are often spots of liquid medicine on the plant and fruit surface, causing appearance pollution; and there are more solvents in pyrimethanil emulsifiable concentrate products , prone to phytotoxicity after use, and will also pollute plants and the environment
