Description

A kind of microcapsule suspending agent for preventing and treating gray mold
Technical field
The present invention relates to a kind of microcapsule suspending agent for preventing and treating gray mold, be specifically related to a kind of for preventing and treating The microcapsule suspending agent of garlic gray mold, belongs 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, belongs to benzene Amine pyrimidine class new type bactericide, stops infecting also of germ by suppressing the generation of infection process enzyme Kill germ.There is suction conduction and fumigation action, after dispenser, be rapidly reached the sprays such as the flower of plant, young fruit Germ is killed at the mist position that is beyond one's reach, drug effect faster, more stable.Particularly to benzimidazole and ammonia The ash arrhizus bacteria effect that carbamate series bactericidal agent has developed immunity to drugs is preferable, but pyrimethanil is used some and made On thing such as eggplant, poisoning easily occur, 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 it is pure Product are white, needle-shaped crystals powder, are soluble in methyl alcohol, ethanol, chloroform, acetone and ethyl acetate etc., no It is dissolved in water and petroleum ether.The botanical pesticide prepared with Osthole, as insecticide to beet night The various pests such as moth, tea geometrid, Colcaphellusbowringi, various aphids all have contact efficacy significantly, its effect Mode is based on action of contace poison, and stomach poison function is auxiliary, and liquid enters in insect bodies by External absorbability, makees For insect nervous system, cause insect muscle non-functional to shrink, finally die of exhaustion.Osthole To people and animals and other mammalian safe, it is not likely to produce anti-medicine, the most degradable.Osthole with Multiple biological pesticide or chemical pesticide compound obvious synergistic effect.
Garlic gray mold early stage forms water stain shape scab on blade, becomes greyish white to taupe later Fleck, the most inwardly extended by blade tip, the later stage expands overlapping in the big spot of bar shaped canescence, and surface has The mould layer of taupe.The harm head of garlic 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 microcapsule suspending agent for preventing and treating gray mold, specifically Relating to a kind of microcapsule suspending agent for preventing and treating garlic gray mold, field efficacy of the present invention is high, it is possible to reduce Poisoning, and the lasting period is long.
