Abstract

A synergistic composite insecticide for preventing and treating red spider contains pyridaben, flucycloxuron, assistant and excipient.

Description

A kind of Synergistic insecticidal compositions and application thereof that contains pyridaben and flucycloxuron
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 flucycloxuron.
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 C20051004143800031
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.
Flucycloxuron (flucycloxuron) belongs to benzoyl area kind and kills mite, insecticide, is chitin synthesis inhibitor.Can prevent and treat goitre mite and tetranychid nymph (invalid) to adult, especially the apple on the apple stings goitre mite, elm (apple) Panonychus citri and Mai Keshi tetranychus telarius, and the ordinary maple leaf mite nymph on the various crops, also can prevent and treat the larva of some a little insect, soybean pretty young woman at night, codling moth are wherein arranged, Lay white butterfly and wild cabbage diamond-back moth.
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 flucycloxuron up to now.
In addition, the resistance of present two spotted spider mite increases gradually, and the agent of agricultural chemicals list descends gradually to the effect of control of insect, gets ingredients and improves drug effect so also be badly in need of a kind of synergy, delays the generation of pest resistance.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can produce higher cooperative synergism, both improved the performance of its quick-acting, again can there be certain lasting period, can overcome and delay pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, has reduced drug cost, Synergistic insecticidal compositions that contains pyridaben and flucycloxuron and application thereof that toxicity is light.
Technical scheme of the present invention is:
A kind of Synergistic insecticidal compositions that contains pyridaben and flucycloxuron, it is characterized in that the composite emulsion preparation that it is made up of primary activity composition pyridaben and flucycloxuron, auxiliary agent and excipients, wherein the weight portion of pyridaben is 0.1~30, the weight portion of flucycloxuron is 0.5~30, the weight portion of auxiliary agent is 3~15, and surplus is an excipients.
Described auxiliary agent is a kind of or its combination in calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxypropylene block compound, the polyoxyethylene nonylphenol ether.
Described excipient is dimethylbenzene or solvent naphtha.
The effective ingredient that contains the Synergistic insecticidal compositions of pyridaben and flucycloxuron of the present invention is present in the composition with the synergy effective dose.
Optimum weight part of pyridaben and flucycloxuron is respectively 0.5~20 and 1~25.
Its application on the control mite pest, its effect is used apparently higher than its single agent.
Its effect the control two spotted spider mite uses apparently higher than its single agent.
Beneficial effect of the present invention:
Measure through indoor synergism test and to show: is 156~238 by pyridaben and flucycloxuron to the co-toxicity coefficient of two spotted spider mite, and test determination shows that all composite dose all has significant synergistic insecticidal action to two kinds of insects; Field control effectiveness test equally also shows the composite dose of effect that the insecticidal effect of beet tops moth larvae all is significantly higher than corresponding single agent agricultural chemicals that the present invention is all.
Pesticidal combination of the present invention is compared with prior art:
(1) compare with single agent, 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.
Embodiment
The present invention is further illustrated below in conjunction with embodiment.
The method that employing indoor bioassay of the present invention and field trial combine, earlier by indoor bioassay, the co-toxicity coefficient after clear and definite two kinds of medicaments are composite by a certain percentage; On this basis, carry out field trial again.
Embodiment 1:
