Abstract
The present invention relates to a kind of for the anti-compounded pesticides eliminated aphis, described compounded pesticides is for preventing and treating cotton aphid, formulation is suspension emulsion, and active ingredient is allicin and pymetrozine, and auxiliary agent is alkylaryl APEO, silkworm excrement, silicone, hydroxyethylcellulose.Compounded pesticides of the present invention not only has higher preventive effect, and reduces the dosage of active ingredient, decreases residue of pesticide, alleviates to use due to agricultural chemicals the harm caused ecotope.
Description
Technical field
The present invention relates to a kind of for the anti-compounded pesticides eliminated aphis, be specifically related to active ingredient be the compounded pesticides of allicin and pymetrozine for preventing and treating cotton aphid, belong to technical field of pesticide.
Background technology
Pymetrozine belongs to pyridines or Triazinone insecticide, and chemical formula is 4,5-dihydro-6-methyl-4-(3-pyridine methylene is amino)-1,2,4-3 (2H)-one, the toxicity of pymetrozine: rat oral LD
50for 1710mg/kg, rat is through skin LD
50>2000mg/kg.Pymetrozine has action of contace poison to insect, also has systemic activity simultaneously.Can also can at phloem transport in xylem transporting in plant corpus; Therefore both can be used as foliar spray, also can be used for soil treatment.Due to the transporting characteristic that it is good, the branches and leaves newly grown after cauline leaf spraying also can be effectively protected.Pymetrozine is to some Important Natural Enemy or beneficial insect, and as the natural enemy coccinella septempunctata of cotton bollworm, chrysopa carnea, the beneficial insects such as the Natural Spider Enemies of leafhopper and Delphacidae are almost harmless.
Allicin (Allicin) is a kind of organosulfur compound extracted from the bulb (garlic) of Liliaceae allium garlic (AlliumSativum), 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 aqueous solution pH 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.
Along with the enhancing of people's environmental consciousness and the raising of scientific research level, hypotoxicity, low-residual, efficiently novel agrochemical are urgently developed, to reduce the impact of the applications of pesticide on surrounding medium.
Summary of the invention
For the problems referred to above, the invention provides a kind of for the anti-compounded pesticides eliminated aphis, being specifically related to active ingredient is that the compounded pesticides of allicin and pymetrozine is for preventing and treating cotton aphid.The dosage of active ingredient of the present invention is few, and the lasting period is long.
