Abstract

The present invention relates to a kind of compositions for preventing and treating gray mold, the dosage form of described compositions is suspending agent, and effective ingredient is osthole and pyrimethanil, and auxiliary agent is alkylaryl polyoxyethylene ether, Bombyx mori L., silicone, hydroxyethyl cellulose.The present invention has extraordinary prevention effect to Bulbus Allii gray mold, and the present invention utilizes the prevention to Bulbus Allii gray mold of osthole and pyrimethanil and the effect for the treatment of, instant effect, and the lasting period is long, on non-Target crops without impact.

Description

A kind of compositions for preventing and treating gray mold
Technical field
The present invention relates to a kind of compositions for preventing and treating gray mold, be specifically related to a kind of compositions for preventing and treating Bulbus Allii gray mold, belong to technical field of pesticide.
Background technology
Pyrimethanil has another name called Shi Jiale, and chemical name is N-(4,6-dimethyl pyrimidine-2-base) aniline, belong to anilino-pyrimidine new type bactericide, stop infecting and killing pathogenic bacteria of pathogenic bacteria by suppressing the generation of infection process enzyme.There is suction conduction and fumigation action, be rapidly reached the spraying such as the flower of plant, the young fruit position that is beyond one's reach after dispenser and kill pathogenic bacteria, drug effect faster, more stable.The ash arrhizus bacteria effect particularly developed immunity to drugs benzimidazole and carbamate fungicide is preferable, but pyrimethanil is used on some crop such as Fructus Solani melongenae, poisoning easily occurs, and when concentration is high or consumption is big, poisoning can be more serious.
Osthole is present in the extract of Umbelliferae annual herb plant Cnidium monnieri in a large number, and its sterling is white, needle-shaped crystals powder, is soluble in methanol, ethanol, chloroform, acetone and ethyl acetate etc., water insoluble and petroleum ether.The botanical pesticide prepared with osthole, as insecticide, the various pests such as beet armyworm, tea geometrid, Colcaphellusbowringi, various aphids all there is contact efficacy significantly, its model of action is based on action of contace poison, stomach poison function is auxiliary, medicinal liquid enters in insect bodies by External absorbability, act on insect nervous system, cause insect muscle non-functional to shrink, finally die of exhaustion.Osthole, to people and animals and other mammalian safe, is not likely to produce drug resistance, the most degradable.Osthole is compounding with multiple biological pesticide or chemical pesticide obvious potentiation.
Bulbus Allii gray mold their early stage forms water stain shape scab on blade, becomes greyish white to taupe fleck later, the most inwardly extended by blade tip, and the later stage expands overlapping in the big speckle of bar shaped canescence, and there is the mould layer of taupe on surface.Harm Bulbus Allii forms taupe scab, bears light/dark balance mustiness thing during high humidity.
Summary of the invention
For the problems referred to above, the invention provides a kind of compositions for preventing and treating gray mold, be specifically related to a kind of compositions for preventing and treating Bulbus Allii gray mold, field efficacy of the present invention is high, it is possible to reduce poisoning, and the lasting period is long.
Technical scheme is as follows:
A kind of compositions for preventing and treating gray mold, the dosage form of described compositions is suspending agent, and effective ingredient is osthole and pyrimethanil, and auxiliary agent is alkylaryl polyoxyethylene ether, Bombyx mori L., silicone, hydroxyethyl cellulose.
