Abstract
The present invention relates to a kind of antibacterial on Bulbus Allii, the dosage form of described antibacterial is suspension emulsion, effective ingredient is osthole and of pyrimethanil, and auxiliary agent is alkyl benzene sulfonate calcium salt, dodecylbenzene sodium sulfonate, acetonitrile, thermally coupled distillation columns, silicone, guar gum, propylene glycol. Bulbus Allii gray mold is had extraordinary prevention effect by the present invention, and the present invention utilizes the effect of the prevention to Bulbus Allii gray mold of osthole and of pyrimethanil and treatment, instant effect, and the lasting period is long, on non-Target crops without impact.
Description
Technical field
The present invention relates to a kind of antibacterial on Bulbus Allii, be specifically related to a kind of antibacterial for preventing and treating Bulbus Allii gray mold, belong to technical field of pesticide.
Background technology
Of 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, by producing thus stoping infecting and killing pathogenic bacteria of pathogenic bacteria of suppression 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 benzimidazole and carbamate fungicide developed immunity to drugs is better, but of pyrimethanil is used on some crop such as Fructus Solani melongenae, it is easy to poisoning occur, 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, it can be used as insecticide that the various pests such as beet armyworm, tea geometrid, Colcaphellusbowringi, various aphids are all had 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 that insect muscle non-functional shrinks, finally die of exhaustion. Osthole, to people and animals and other mammalian safe, is not likely to produce drug resistance, degradable in the environment. Osthole and multiple biological pesticide or chemical pesticide is composite obvious potentiation.
Bulbus Allii gray mold their early stage forms water stain shape scab on blade, becomes greyish white to taupe fleck later, inwardly extended gradually by blade tip, and the later stage expands overlap and has a bar shape the big speckle of 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 antibacterial on Bulbus Allii, be specifically related to a kind of antibacterial on Bulbus Allii 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.
