Abstract
The invention relates to a combination containing urea fluoride and organophosphorus insecticide, particularly to a highly active low toxicity compound pesticide combination containing urea fluoride and chlorpyrifos, comprising elementary compositions of urea fluoride 0.1%-20% and chlorpyrifos 5%-50% and the balance additive and solvent. The compound pesticide has the advantages of stronger synergism, reduced using cost, reduced toxicity, enlarged insecticidal spectrum, quickened extermination speed on pests, thereby overcoming and delaying generation of drug resistance. The combination can be used for preventing lepidoptera pesticides on crops, fruit trees and vegetables, particularly for preventing ricestem borer, budworm of the fruit trees and cotton bollworm and the like, the effect excels evidently than single pesticides.
Description
Technical field
The present invention relates to a kind of Pesticidal combination and uses thereof, Synergistic insecticidal composition and the application thereof of especially a kind of fluorine-containing uride and chlopyrifos.
Background technology
Fluorine uride (novaluron), chemical name 1-[3-fluoro-4-(1,1,2-three fluoro-2-(trifluoro methoxy) second is supported base) phenyl]-3-(2, the 6-difluoro benzoyl) urea, by the exploitation of Israel Makhteshim chemicals Co., Ltd, CAS 116714-46-6.
Structural formula:
The fluorine uride belongs to process for preparation of benzoylurea compounds, be a kind of insect growth regulator, IGR, it is chitin synthesis inhibitor, can be applicable on various agricultural such as cotton, soybean, corn, fruit tree, vegetables and the horticultural crop, to many pest efficients, remarkable as drug effects such as cotton bollworm, heart-eating worm, leaf roller, diamond-back moth, cabbage caterpillar, pine caterpillars, aleyrodid, thrips.
This kind wide spectrum, efficient, low toxicity, low-residual, environmentally friendly, selectivity is good, is that the ideal of pollution-free food medication is selected.
Fluorine uride price height is difficult to large tracts of land and promotes a few days ago, can only be confined to the higher economic crops of added value.Chlopyrifos belongs to low toxicity organic phosphor kind, insecticidal spectrum is wide, have the stomach toxicity of tagging and fumigation action, and has certain acaricidal activity, be that a few substitutes one of outstanding kind of high malicious organic phosphor at present, but it is short that it still has the machine phosphorus insecticide lasting effect, and to the active shortcoming on the low side of above the average age for marriage lepidopterous larvae.Thereby use single agent can not reach to the best control efficiency of insect.
Lepidoptera pest, as cotton bollworm, the snout moth's larva of rice, heart-eating worm, sweet bud noctuid, cabbage caterpillar, diamond-back moth etc., because the long-term organophosphorus insecticide that uses, kind is single, thereby resistance increase fast, control efficiency descends gradually, and complex preparation can significantly improve drug effect, and delays the generation of pest resistance to insecticide.
The content of invention:
Technical problem to be solved by this invention is in order to overcome above-mentioned the deficiencies in the prior art, a kind of Lepidoptera that prevents and treats to be provided, Homoptera and acarine be the Synergistic insecticidal composition and the application thereof of main active ingredient with fluorine uride and chlopyrifos.
The technical scheme that the present invention solves the problems of the technologies described above employing is a kind of fluorine-containing uride and chlopyrifos Synergistic insecticidal composition, it is characterized in that with fluorine uride and chlopyrifos be the primary activity composition, it is formulated through processing to add auxiliary agent and solvent, wherein the mass fraction of each component is, fluorine uride 0.1-20 part, chlopyrifos 5-50 part, auxiliary agent 5-15 part, surplus is a solvent.
Described auxiliary agent is a calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, in polyoxyethylene polyoxypropylene block compound or the polyoxyethylene nonylphenol ether one or more formed, and solvent is a kind of in solvent naphtha, toluene, dimethylbenzene, methyl alcohol, ethanol, acetone, butanone, pentanone, cyclohexanone, dimethyl formamide, dimethyl sulfoxide (DMSO), N-Methyl pyrrolidone, carrene, dichloroethane, the chloroform etc. or their combination.
The present invention by fluorine uride and chlopyrifos Synergistic insecticidal compositions be effective ingredient with synergy dosage in composition.
The best in quality umber of fluorine uride is 0.1-20 part in the Synergistic insecticidal compositions of fluorine-containing uride of the present invention and chlopyrifos, and chlopyrifos is 5-50 part.
Insecticides of the present invention can be used for preventing and treating insects such as Lepidoptera, Homoptera, acarian.
Pesticidal combination of the present invention can be used for preventing and treating cotton bollworm, fruit tree budworm, the snout moth's larva of rice, beet armyworm.
Insecticide combination of the present invention has the following advantages:
(1) compare with single agent, said composition synergy is obvious, improves preventive effect.
(2) enlarge insecticidal spectrum, reduced the control cost.
(3) alternative high-toxic pesticide helps environmental protection and has reduced residue of pesticide.
(4) reduced toxicity to warm blooded animal.
(5) compare with the agent of fluorine uride list, the medicine valency reduces, and use cost reduces.
(6) it is serious particularly to can be used for preventing and treating domestic present generation, the cotton bollworm of difficult control, the snout moth's larva of rice, rice leaf roller, striped rice borer, paddy stem borer, beet armyworm, diamond-back moth, cabbage caterpillar.
Embodiment
The invention will be further described below in conjunction with embodiment:
The present invention is the method that adopts indoor bioassay and field trial to combine, and at first by indoor bioassay, two kinds of active ingredient fluorine urides proportioning different with chlopyrifos is composite, carries out the mensuration of co-toxicity coefficient, on this basis, carries out field trial again.
