Imidacloprid is nitro-methylene-type systemic insecticide, is the acting body of nicotinic acid nAChR ligands, disturbs pest movements nervous system that chemical signal is transmitted malfunctioning, without cross resistance problem.Be used for preventing and treating sucking pest and resistant strain thereof.Imidacloprid is chloro nicotine insecticide of new generation, has wide spectrum, efficient, low toxicity, low-residual, and insect is difficult for producing resistance, to features such as people, animal, plant and natural enemies securities, and have tag, stomach toxicity and the multiple drug effect of interior suction.After insect contact medicament, nervous centralis normal conduction is obstructed, and makes its paralysis dead.Quick-acting is good, within after medicine 1 day, has higher preventive effect, and residual life reached about 25 days.Drug effect and temperature are proportionate, and temperature is high, good disinsection effect.Be mainly used in preventing and treating sucking pest.Be mainly used in preventing and treating the sucking pest on the crops such as paddy rice, wheat, cotton, as aphid, leafhopper, thrips, trialeurodes vaporariorum and colorado potato beetle and wheat stem maggot etc.
Often there is defect in the insecticide variety containing single component: use is easily developed immunity to drugs continuously, and insecticidal spectrum is narrow, can not provide comprehensive protection for crop, and peasant's drug cost is high in agricultural chemicals control of insect.By two kinds or being combined in to a certain extent of two or more active components, can overcome to a certain extent above-mentioned shortcoming.There is two kinds of synergistic effect or the combination of two or more active components and be mixed, can improve preventive effect, reduce active ingredient ground dosage, cost-saving, slow down pest resistance occur, and can expanding prevention spectrum, play that many worms are double to be controlled, reduce peasant's use cost.
Summary of the invention
The Synergistic insecticidal compositions that the object of this invention is to provide a kind of clothianidin-containing and Imidacloprid, said composition can be used for preventing and treating various agricultural insect, such as preventing and treating rice hoppers or wheat worm and thrips etc., can reach the effect of Synergistic.
The Synergistic insecticidal compositions that another object of the present invention is to provide clothianidin-containing and Imidacloprid is prevented and treated the application in the insecticidal materials of one or more insects in resistance Semiptera, coleoptera, Lepidoptera or Hymenoptera in preparation.
The present invention adopts following technical scheme:
A Synergistic insecticidal compositions for clothianidin-containing and Imidacloprid, it take clothianidin and Imidacloprid is main active ingredient, wherein, the weight ratio of clothianidin and Imidacloprid is 0.1 ~ 90:0.1 ~ 90.Be preferably 1 ~ 60:1 ~ 70, more preferably 1 ~ 30:1 ~ 30, then the weight ratio of further preferred clothianidin and Imidacloprid are 1 ~ 10:1 ~ 10, and most preferably the weight ratio of clothianidin and Imidacloprid is 1:1 ~ 10.This Synergistic insecticidal compositions can only contain active ingredient clothianidin and Imidacloprid, also can when using or prepare, in active component, add other components, and the effective ingredient of above-mentioned Insecticidal combinations is present in composition with synergy effective dose.
At the Synergistic insecticidal compositions of clothianidin-containing of the present invention and Imidacloprid, the two weight percentage in this Synergistic insecticidal compositions of clothianidin and Imidacloprid is 2% ~ 80%, is preferably 8% ~ 60%, and optimum is 20% ~ 40%.
The Synergistic insecticidal compositions of above-mentioned clothianidin-containing and Imidacloprid be take clothianidin and Imidacloprid and is mixed with any one formulation allowing on agricultural chemicals as main active ingredient (active component) and insecticides adjuvant, excipients.The preferred pulvis of formulation, wetting powder, suspending agent, missible oil and water dispersion granule.
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, alkylphenol polyoxyethylene, the rare block compound 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 cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and the upper known auxiliary material of other agricultural can alone or and use.
Application in the insecticidal materials of above-mentioned clothianidin-containing and the Synergistic insecticidal compositions of Imidacloprid one or more insects in preparation control Semiptera, Lepidoptera, Hymenoptera or coleoptera.Especially the effect of preventing and treating in the insecticidal materials of rice hoppers or wheat aphid and thrips in preparation is remarkable.
Synergistic insecticidal compositions antagonism Semiptera insect of the present invention has significant preventive effect, especially for the easy various pests that produces resistance such as wheat aphid and rice fulgorid, has good preventive effect; And suppress insect the pesticide resistance of unitary agent (clothianidin or Imidacloprid) is produced.
The insecticidal materials of being prepared by the Synergistic insecticidal compositions of described clothianidin-containing and Imidacloprid is when preventing and treating resistance Lepidoptera, Hymenoptera or coleopteran pest, can prevent and treat Semiptera insect again, especially rice hoppers or wheat aphid and thrips are had to good preventive effect, improve drug effect, reached the effect that a medicine is controlled more.
Pesticidal combination of the present invention compared with prior art, produces following beneficial effect: (1) is compared with single dose, and said composition insect has notable synergistic, 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 significantly reduce field dosage, effectively reduce environmental pollution and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with Imidacloprid single dose, produce and use cost reduction; (6) suppressing insect strengthens the resistance of agricultural chemicals;
