Abstract
A composite pesticidal composition comprising chlorfluazuron and spinetoram and uses thereof are disclosed. The composition adopts the chlorfluazuron and the spinetoram as pesticidal active components, wherein the weight ratio of the chlorfluazuron to the spinetoram being 0.1-80:0.5-80. The composition can generate a high synergistic interaction, overcomes and delays pest resistance to pesticides, is high in pest killing speed, long in duration of efficacy, and reduced in pesticide using cost, and has control effects obviously higher than effects when a single pesticide is used. The composition can control lepidoptera pests on crops, especially can control cotton bollworm and stem borers, and has effects obviously higher than the effects when a single pesticide is used.
Description
Technical field
The invention belongs to the field of agricultural pesticide containing heterocyclic compound, be specifically related to a kind of compound pesticide compositions and the application thereof that contain chlorfluazuron and ethyl pleocidin.
Background technology
Ethyl pleocidin (Spinetoram), structural formula is:
XDE-175-J is the novel pleocidin insecticides of one of being produced by Dow AgroSciences, and receive first whole world registration, it effectively can control the important insect pest on fruit tree and nut, a kind of thorny primary pest especially on fruit tree---the stupid moth of apple.Be mainly used in control lepidopterous larvae, thrips and Liriomyza etc., to the control efficiency that diamond-back moth, beet armyworm, Liriomyza, thrips, prodenia litura, lima bean pod borer have had.
Chlorfluazuron (Chlorfluazuron), chemical name: 1-(the chloro-4-of 3,5-bis-(the chloro-5-trifluoromethyl of 3--2-pyridine oxygen base) phenyl)-3-(2,6-difluoro benzoyl) urea, structural formula is:
Chlorfluazuron is a kind of widely used growth regulator, tool stomach toxicity, action of contace poison.The mechanism of action suppresses chitin synthesis, and hinder insect normally to cast off a skin, make the developmental deformity of the hatching of ovum, larval molting and pupa, adult eclosion is obstructed.Drug effect is high, and speed of action is comparatively slow, and to multiple lepidoptera pest, and orthoptera, coleoptera, Hymenoptera, diptera isoreactivity are high.
Containing the insecticide variety of single component often existing defects in agricultural chemicals control of insect: use is easily developed immunity to drugs continuously, and insecticidal spectrum is narrow, and can not provide comprehensive protection for crop, peasant's drug cost is high.To a certain extent can the above-mentioned shortcoming of customer service by two kinds or being combined in of two or more active component.There is two kinds of synergistic effect or the combination mixture of two or more active component, can preventive effect be improved, reduce active ingredient ground dosage, cost-saving, slow down pest resistance and to occur and can expanding prevention spectrum, play that many worms are double to be controlled, reduce the use cost of peasant.
Summary of the invention
The object of this invention is to provide a kind of compound pesticide compositions containing chlorfluazuron and ethyl pleocidin, this Pesticidal combination is the multifunctional insecticide composition of control lepidoptera pest.
Another object of the present invention is to provide this Pesticidal combination and is preparing the application prevented and treated on the insecticidal materials of resistance lepidoptera pest, the application particularly on the insecticidal materials preparing control cotton bollworm or snout moth's larva.
The object of the invention is to be achieved through the following technical solutions:
Containing a compound pesticide compositions for chlorfluazuron and ethyl pleocidin, this compound pesticide compositions is with chlorfluazuron and ethyl pleocidin for principle active component, and wherein, the weight ratio of chlorfluazuron and ethyl pleocidin is 0.1 ~ 80:0.5 ~ 80.
In compound pesticide compositions of the present invention, the weight ratio of chlorfluazuron (A) and ethyl pleocidin (B) is preferably 0.5 ~ 50:1 ~ 50, and more preferably 1 ~ 17:1 ~ 20, most preferably are 1 ~ 10:1; The another kind of preferably weight ratio that scheme is both A and B is 0.1 ~ 20:1, more preferably 0.1 ~ 10:1.
Compound pesticide compositions of the present invention only containing active component chlorfluazuron and ethyl pleocidin, also can add other components when using or prepare in active component.
In compound pesticide compositions of the present invention, both chlorfluazuron and the ethyl pleocidin weight percentage in this compound pesticide compositions is 3% ~ 80%, is preferably 5% ~ 55%, most preferably 10% ~ 40%.
Compound pesticide compositions of the present invention with chlorfluazuron and ethyl pleocidin for active component or principle active component, any one formulation that agricultural chemicals allows is become, the preferred missible oil of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion or water dispersion granule with insecticides adjuvant and excipient.
Aforementionedly can be applicable to the not special restriction of insecticides adjuvant of the present invention, include, but are not limited to calcium dodecyl benzene sulfonate, 600#, the rare block copolymer of polyoxyethylene polyoxy third (as agriculture breast 33#), polyoxyethylene nonylphenol ether etc., aforementionedly can be applicable to excipient of the present invention and be also not particularly limited, include, but are not limited to solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can be alone or and use.
Compound pesticide compositions of the present invention has good preventive effect to the multiple Semiptera of the easy generation such as rice fulgorid and snout moth's larva resistance and lepidoptera pest; And suppress insect to produce the pesticide resistance of unitary agent (chlorfluazuron or ethyl pleocidin arbitrary).
Compound pesticide compositions of the present invention is preparing the application prevented and treated on resistance lepidoptera pest insecticidal materials, and the effect especially on preparation control cotton bollworm or snout moth's larva insecticidal materials is remarkable.
Compared with prior art beneficial effect of the present invention: (1) is compared with single dose, said composition antagonism lepidoptera pest is obvious synergistic function as cotton bollworm, snout moth's larva etc. have, and overcomes and has delayed pest resistance to insecticide, and expanding prevention is composed, desinsection speed is fast, significantly improves control efficiency; (2) control recruitment, drug cost is reduced; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) with chlorfluazuron compared with ethyl pleocidin single dose, produce and use cost reduction; (6) suppress lepidoptera pest to strengthen the resistance of agricultural chemicals, its successful uses higher than its single dose.
