Abstract

The invention relates to a water emulsion with allicin and validamycin A as effective ingredients. The effective ingredients are allicin and validamycin A, and the auxiliaries are calcium alkylbenzene sulfonate, N-pyrrolidone, glycerol, organic silicon and guar gum. The water emulsion is obtained through a conventional preparation process, and the water emulsion composition has good preventing and controlling effects on phyricularia oryzae. Since the bactericidal activities of the allicin and the validamycin A have a synergistically adding effect, the effects of preventing and controlling the phyricularia oryzae are effectively enhanced, the obvious preventing and controlling effect can be achieved in early stage or later of pathogenesis, and the lasting period is long.

Description

Active ingredient is the aqueous emulsion of allicin and jinggangmycin A
Technical field
The present invention relates to the aqueous emulsion that active ingredient is allicin and jinggangmycin A, the active ingredient be specifically related to for preventing and treating rice blast is the aqueous emulsion of allicin and jinggangmycin A, belongs to field of biological pesticide.
Background technology
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.
Jinggangmeisu comprises jinggangmycin A and jinggangmeisu (mixture of jinggangmycin A and its isomer B, C, D, E, F), at present by the single dose of national agriculture chemical registration, is mainly used in control crop rice blast.Its compound formulation includes, composite with waxy Bacillus, for preventing and treating rice blast, rice blast, head blight; Composite with carbendazim, for preventing and treating rice blast, rice blast, head blight; Composite with tricyclazole, for preventing and treating rice blast, rice blast, false smut; Composite with carbendazim, for preventing and treating rice blast, false smut; With olefin conversion or ucleosides antibiotic composite, for preventing and treating rice blast, false smut; With own azoles alcohol or oxyenadenine composite, for preventing and treating rice blast; Composite with bacillus subtilis, for preventing and treating false smut.Jinggangmeisu is to people and animals' low toxicity, and to birds fish safety, absorption farm antibiotics series bactericidal agent in belonging to, by disturbing and suppressing pathogen cell normal growth to be grown, plays therapeutic action.
Rice blast has another name called rice blast, and the reasons such as the generation of this disease and environment, host, kind and control are in close relations, and sunshine is few, and the mountain area that the mist dew duration is long and the relatively mild riparian area morbidity of weather weigh.In the popular time, general underproduction 10%-20%, heavy underproduction 40%-50%, even No kernels or seeds are gathered, as in a year of scarcity for local field.Rice blast all can occur in paddy rice whole breeding time, rice shoot of causing harm, fringe, joint etc., is called seedling pest, leaf pest, fringe pest and joint pest.The county does not also find that seedling pest occur at present, mainly leaf pest, fringe pest and joint pest.Identify its symptom, for the Accurate Diagnosis state of an illness, carry out observe and predict with preventing and controlling all extremely important.
In prior art, the usage amount of agricultural chemicals is increasing, not only makes crop produce resistance, also brings serious pollution to environment, for the problems referred to above, the invention provides the aqueous emulsion that active ingredient is allicin and jinggangmycin A.
Technical scheme of the present invention is as follows:
Active ingredient is the aqueous emulsion of allicin and jinggangmycin A, and active ingredient is allicin and jinggangmycin A, and auxiliary agent is alkyl benzene calcium sulfonate, N-pyrrolidones, glycerine, organosilicon, melon glue.
