Abstract

A synergistic composite insecticide for preventing and controlling the agricultural mite and red spider contains two active components including proportionally pyridaben, assistant, and excipient.

Description

A kind of Synergistic insecticidal compositions and application thereof that contains pyridaben and fluacrypyrim
Technical field
The present invention relates to a kind of Pesticidal combination and uses thereof, especially a kind of is the Pesticidal combination and the application thereof of main active with pyridaben and fluacrypyrim.
Background technology
Pyridaben (adopted name: Pyridaben) chemical name: 2-tertiary butyl-5-(4-tertiary butyl benzylthio)-4-chloro-3 (2H)-pyridazinone
Chemical structural formula:
Figure C20051004144400031
Key property: Insecticidal and acaricidal agent, wide spectrum, efficient, hold and imitate longly, have action of contace poison.
Controlling object: citrus: Panonychus citri, tetranychid, unguiculus mite, beginning tetranychid, rust mite, aleyrodid, aphid etc.; Cotton: cotton spider mites, cotton leafhopper etc.; Apple: tetranychid, rust mite, aphid etc.
Fluacrypyrim (test code number: NA83, adopted name: fluacrypyrim, trade name: Titaron) be first methoxy acrylic miticide by BASF AG development, the exploitation of Japanese Cao Da company.Fluacrypyrim is on the basis of methoxy acrylic bactericide, and is synthetic at random, and find through optimization.The chemical name of fluacrypyrim is methyl (E)-2-{a-[2-isopropoxy-6-(trifluoromethyl) pyrimidine-4-base oxygen base]-o-tolyl }-the 3-methoxy-methyl acrylate.
Fluacrypyrim is that the mitochondrial respiratory inhibitor promptly shifts the mitochondrial breathing of inhibition by electronics between cytochrome b and cl.Extranuclear mitochondria mainly by breathing to cell provides energy (ATP), if mitochondrial respiratory is obstructed, can not produce ATP, and cell will be dead.
Fluacrypyrim is mainly used in multiple mite class such as European red mite, the citrus red mite etc. in control fruit tree such as apple, citrus, the pears etc.The mixture main component is that methoxy acrylic ester compounds such as fluacrypyrim and a lot of organophosphorus compound are formed in the patent, is used for anti-ly curing the disease, insect pest.Two spotted spider mite increases gradually in present resistance, the agent of agricultural chemicals list descends gradually to the effect of control of insect, and the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve desinsection quick-acting and lasting effect, but still finds no the Pesticidal combination that closes pyridaben and fluacrypyrim up to now.
Summary of the invention
The purpose of this invention is to provide that a kind of what prevent and treat mite pest is the Pesticidal combination and the application thereof of main active with pyridaben and fluacrypyrim.
Technical scheme of the present invention is:
A kind of Synergistic insecticidal compositions that contains pyridaben and fluacrypyrim, it is characterized in that it is by primary activity composition pyridaben, fluacrypyrim, auxiliary agent, the composite cream preparation that forms of excipients, the weight portion of each component is: 0.1~30 part of pyridaben, fluacrypyrim: 0.5~30, auxiliary agent: 3~15, excipients: surplus.
Described auxiliary agent is the one or more combinations in calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxypropylene block compound or the polyoxyethylene nonylphenol ether, and excipient is dimethylbenzene or solvent naphtha or its combination.
The Synergistic insecticidal compositions that contains pyridaben and fluacrypyrim of the present invention is that effective ingredient is present in the composition with the synergy effective dose.
Optimum weight part of pyridaben and fluacrypyrim is respectively 0.5~20 and 1~25 in the composition.
The application of Pesticidal combination of the present invention on the control mite pest, the especially application on the control two spotted spider mite.
Beneficial effect of the present invention:
Pesticidal combination of the present invention compared with prior art produces following beneficial effect: (1) is compared with single agent, and said composition has notable synergistic to lepidoptera pest, has obviously improved control efficiency; (2) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, reduce control recruitment cost; (3) alternative high-toxic pesticide, and reduce the field dosage significantly, effectively reduce environmental pollution and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with single agent product, produce and the use cost reduction; (6) suppress the resistance enhancing of lepidoptera pest to agricultural chemicals; (7) reduction is to the toxicity of warm blooded animal.
