Powdery mildew of cucumber is had extraordinary prevention effect by the present composition, the present invention utilizes the bactericidal activity of Tebuconazole and garlicin to have good synergism, effectively enhance the effect of the prevention to powdery mildew of cucumber and treatment, morbidity early stage dispenser 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 Tebuconazole and garlicin bactericidal composition, be specifically related to Tebuconazole and garlicin bactericidal composition for preventing and treating powdery mildew of cucumber, belong to technical field of pesticide.
Background technology
Tebuconazole belongs to triazole bactericidal agent, is sterol demethylation inhibitor. Tebuconazole is a kind of efficient, wide spectrum, interior absorption triazole bactericidal agent, has protection, treats, roots out three zones, and fungicidal spectrum is wide, the lasting period is long. These product are used for preventing and treating sclerotinia rot of colza, and not only preventive effect is good, and have resistant to lodging, the features such as production-increasing function is obvious. It is the seed treatment for Important Economic crop or the efficient germicide of face sprinkling, can effectively prevent and treat the multiple rust of cereal crop, powdery mildew, net blotch, root rot, head blight etc.
Garlicin (Allicin) is a kind of organosulfur compound extracted from the bulb (Bulbus Allii head) of Liliaceae allium Bulbus Allii (AlliumSativum), exists in Bulbus Allii Cepae and other alliums. Formal name used at school GIUCOSinoate. Pale yellow oily liquid body. Boiling point 80-85 DEG C (0.2kPa), relative density 1.112(20/4 DEG C), index of refraction 1.561. It is dissolved in ethanol, chloroform or ether. Dissolubility 2.5% (quality) (10 DEG C) in water, its pH value of water solution is 6.5, has grease precipitate to be formed during standing. Can dissolve each other with ethanol, ether and benzene. Thermokalite is unstable, acid is stable. By in the bulb being present in liliaceous plant Bulbus Allii, the garlic aminoacid existed converting generation under big allinase effect. Exist in the bulb of Herba Alii fistulosi. Having strong big garlic odour, taste is peppery.
The industrial crops cultivated areas such as the difficulty of prevention and cure of current phytopathogen is increasing, on the one hand, along with the change of pattern of farming, melon fruits and vegetables progressively expand, and disease occurrence degree, occur quantity all to increase, and in preventing and treating, difficulty strengthens; On the other hand, the resistance of pathogen rises year by year under lasting medicament selection pressure, and the prevention effect of single dose is more and more weak, and control of plant disease faces significant challenge.
