Abstract
The invention relates to a insecticidal composition which comprises fluorine acyl urea and organophosphorus and the application thereof, especially a high efficiency and low toxicity compound insecticide which comprises fluorine acyl urea and phoxim, the basic component of which is 0.1%-20% of fluorine acyl urea and 5%-50% of phoxim, other components are accessory ingredient and menstruum. The advantages of the composition is that the composition has relatively high synergetic effect, lowers application cost and toxicity, expands the insecticidal spectrum, accelerates the injurious insect knockdown speed, prevents and delays the resistance to agricultural chemical of injurious insect, and the composition can prevent lepidopterous pests on crops, fruit tree, and vegetables, and the like, especially prevent rice stem borer, fruit borer, cotton bollworm, etc; the effect of the composition is obviously better than simple dosage.
Description
Technical field
The present invention relates to a kind of Pesticidal combination and uses thereof, the Synergistic insecticidal compositions and the application thereof of especially a kind of fluorine uride and phoxim.
Background technology
Fluorine uride (novaluron), chemical name 1-[3-fluoro-4-(1,1; 2-three fluoro-2-(trifluoromethoxy ethyoxyl) phenyl]-3-(2; the 6-difluoro benzoyl) urea is 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 at present, can only be confined to the higher economic crops of added value.Phoxim (phoxim) is a kind of efficient, low toxicity, broad-spectrum organic insecticide, have stomach toxicity, action of contace poison, the speed of knocking down is fast, lasting period is short, be mainly used in the inside and outside parasite of insect such as various pests on the crops such as control grain, cotton, vegetables, fruit tree and soil, storage, health and poultry body etc., be that a few substitutes one of outstanding kind of high malicious organic phosphor at present, but it have organophosphorus insecticide lasting effect weak point, 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 progress phase is used organophosphorus insecticide, kind is single, thereby resistance increases, control efficiency descends gradually, and complex preparation can significantly improve drug effect, and delays the generation of pest resistance.
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 phoxim.
The technical scheme that the present invention solves the problems of the technologies described above employing is a kind of fluorine-containing uride and phoxim Synergistic insecticidal compositions, it is characterized in that with fluorine uride and phoxim 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, phoxim 5-50, auxiliary agent 5-15, 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, cyclohexanone, dimethyl formamide, dimethyl sulfoxide (DMSO), N-Methyl pyrrolidone, carrene, chloroform, the dichloroethane etc. or their combination.
The present invention by fluorine uride and phoxim Synergistic insecticidal compositions be effective ingredient with synergy dosage in composition.
The best in quality umber of fluorine uride is 0.1-20 in the Synergistic insecticidal compositions of fluorine-containing uride of the present invention and phoxim, and phoxim is 5-50.
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.
