Abstract

The invention relates to an aqueous emulsion for flos chrysanthemi. The aqueous emulsion is used for preventing and treating flos chrysanthemi anthrax, effective ingredients are difenoconazole and allicin, and auxiliaries are white dextrin, polyethylene glycol, silicone oil, styrene polyoxyethylene ether ammonium sulfate and ethanol. The aqueous emulsion has very good preventing and treating effects on flos chrysanthemi anthrax; by using the characteristic that difenoconazole and allicin have a relatively good synergistic effect on the flos chrysanthemi anthrax, the preventing and treating actions on the flos chrysanthemi anthrax are effectively enhanced, and the aqueous emulsion is high in effect taking speed and long in lasting period and does not affect non-target crops.

Description

A kind of aqueous emulsion for chrysanthemum
Technical field
The present invention relates to a kind of aqueous emulsion for chrysanthemum, be specifically related to a kind of aqueous emulsion for preventing and treating chrysanthemum anthracnose, its active ingredient is Difenoconazole and allicin, belongs to technical field of pesticide.
Background technology
The functions such as chrysanthemum has diseases prevention, cures the disease, keeps healthy, appreciation, chrysanthemum is used as medicine with a long history in China, there is dispelling wind, heat-clearing, improving eyesight, detoxicating functions, chrysanthemum and preparation thereof can treat headache, dizzy, the disease such as hot eyes, treatment sore, pyogenic infections, virus flu, hypertension, high fat of blood, coronary heart disease, are the health food liked of people and desirable medicine.Meanwhile, chrysanthemum is again one of China's bulk medicinal materials, is also one of important outlet medicinal material kind.Chrysanthemum morifolium artificial cultivation is the trend of the times of Producing medicinal herbs, and the raw-material high-quality of traditional Chinese medicine, safety in production are the prerequisites of the modernization of Chinese medicine.Only have some traditional Chinese medicinal materials assortments of a few countries artificial cultivation such as Japan, the U.S., Korea S and Southeast Asia abroad, but the current artificial cultivation traditional Chinese medicinal materials assortment of China reaches kind more than 300, accounts for about 2/3 of more than the 500 kind of parts of generic medicinal plants circulated in China's medicinal material market.China has more than 600 traditional Chinese medicine planting base, and cultivated area has reached more than 600 ten thousand mu.But in recent years, China mainland traditional Chinese medicine export volume only accounts for about 10% of global trade amount, main cause is that the understable and medicinal material Pesticide Residues of raw material active ingredient or content of beary metal exceed standard.
Difenoconazole is a kind of pathogen ergosterol biosynthesis inhibitor, acts on the interruption of ergosterol synthesis in phytopathogen thalline, and then shows as strong bacteriostasis.This medicament disinfecting spectrum is wide, the lasting period long, have excellent bacteriostatic activity to the fungi of sac fungi, imperfect fungus and Basidiomycetes, goes out excellent prevention, treatment and eradicant action at variable rate technology; To crop and Environmental security.
Allicin (Allicin) is a kind of organosulfur compound extracted from the bulb (garlic) of Liliaceae allium garlic (Allium Sativum), is also present in onion 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.Be dissolved in ethanol, chloroform or ether.Solvability 2.5% (quality) (10 DEG C) in water, its pH value of water solution is 6.5, has grease sediment to be formed time standing.With ethanol, ether and benzene can dissolve each other.Unstable to thermokalite, acid is stablized.By being present in the bulb of liliaceous plant garlic, under large allinase effect, transform generation by the garlic aminoacid existed.Also be present in the bulb of green onion.Have strong large garlic odour, taste is peppery.
In the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistant insect.Heterogeneity is carried out composite, according to practical application effect judge certain composite be synergy, add and or antagonism.
Summary of the invention
For the problems referred to above, the invention provides a kind of aqueous emulsion for chrysanthemum, the present invention is a kind of aqueous emulsion for preventing and treating chrysanthemum anthracnose, and its active ingredient is Difenoconazole and allicin, and instant effect of the present invention, holding effect are long, to non-target crop safety.
