Description

A kind of microemulsion for chrysanthemum
Technical field
The present invention relates to a kind of microemulsion for chrysanthemum, be specifically related to a kind of micro emulsion for preventing and treating chrysanthemum anthracnose Agent, its active ingredient is Difenoconazole and allicin, belongs to technical field of pesticide.
Background technology
Chrysanthemum have diseases prevention, cure the disease, keep healthy, the function such as appreciation, chrysanthemum is used as medicine with a long history in China, have dispelling wind, Heat-clearing, improving eyesight, detoxicating functions, chrysanthemum and preparation thereof can treat headache, dizziness, hot eyes, treatment sore, pyogenic infections, virus flu, high blood The diseases such as pressure, high fat of blood, coronary heart disease, are the health food liked of people and preferable medicine.Meanwhile, chrysanthemum is again that China is large One of medicinal material, is also one of important outlet medicinal material kind.Chrysanthemum morifolium artificial cultivation is the trend of the times of Producing medicinal herbs, The raw-material high-quality of Chinese medicine, safety in production are the premises of the modernization of Chinese medicine.External only Japan, the U.S., Korea S and Southeast Asia Etc. some traditional Chinese medicinal materials assortment of a few countries artificial cultivation, but China's current artificial cultivation traditional Chinese medicinal materials assortment reaches kind more than 300, accounts for me About the 2/3 of more than the 500 kind of parts of generic medicinal plants circulated on state's medicinal material market.Existing more than 600 the Chinese medicine planting base of China, plants Plant area and reach more than 600 ten thousand mu.But in recent years, China mainland Chinese medicine export volume only accounts for about the 10% of global trade amount, mainly Reason is that raw material active ingredient is understable to exceed standard with medicinal material Pesticide Residues or content of beary metal.
Difenoconazole is a kind of pathogen ergosterol biosynthesis inhibitor, acts on wheat in phytopathogen thalline The interruption of angle sterol synthesis, and then show as strong bacteriostasis.This medicament disinfecting spectrum is wide, lasting period length, to sac fungus, half Know that the fungi of bacterium and Basidiomycetes has excellent bacteriostatic activity, go out prevention, treatment and the eradicant action of excellence at variable rate technology; To crop and Environmental security.
Allicin (Allicin) is from the bulb (garlic) of Liliaceae allium garlic (Allium Sativum) A kind of organosulfur compound extracted, exists 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.It is dissolved in second Alcohol, chloroform or ether.Solubility 2.5% (quality) (10 DEG C) in water, its pH value of water solution is 6.5, has grease to precipitate during standing Thing is formed.Can dissolve each other with ethanol, ether and benzene.Unstable to thermokalite, stable to acid.By the squama being present in liliaceous plant garlic In stem, the garlic aminoacid existed under big allinase effect, convert generation.Exist in the bulb of green onion.There is strong garlic Smelly, taste is peppery.
In the real process of agricultural production, pest control is easiest to generate the problem that the generation of pest resistance to insecticide.No Compound with kind composition, be to prevent and treat the method that resistant insect is the most common.Heterogeneity compounds, according to reality application effect Fruit judge certain compounding be synergy, add and or antagonism.
Summary of the invention
For the problems referred to above, the invention provides a kind of microemulsion for chrysanthemum, the present invention is that one is used for preventing and treating chrysanthemum The microemulsion of flower anthracnose, its active ingredient is Difenoconazole and allicin, and instant effect of the present invention, holding effect are long, to non-target Crop safety.
Technical scheme is as follows:
A kind of microemulsion for chrysanthemum, described microemulsion is used for preventing and treating chrysanthemum anthracnose, and active ingredient is phenyl ether methyl cyclic Azoles and allicin, auxiliary agent is naphthalene sulfonic acid-formaldehyde condensation product sodium salt, Nekal BX, DMF, phenyl phenol polyoxy second Base ether phosphate, C8-10Aliphatic alcohols, Arabic gum, glycerine.
Further, each raw material components of the present invention is by weight percentage:
