Abstract
The invention discloses a compound pesticidal composition containing chlorpyrifos and methoxyfenozide and application thereof. The pesticidal composition uses chlorpyrifos and methoxyfenozide as main effective components, wherein the weight ratio of the chlorpyrifos to the methoxyfenozide is (0.1-80):(0.5-80). The pesticidal composition can generate higher synergic effect, overcomes and postpones the drug resistance of pests, has the advantages of high pesticidal speed and long duration time, lowers the pesticide cost, and has obviously higher preventing and treating effects than a single agent. The pesticidal composition can be used for preventing and treating Homoptera, Lepidoptera, Hemiptera, Coleoptera, Hymenoptera, Diptera, Thysanoptera and acarid pests on crops, especially has specially good effect on preventing and treating rice fulgorids and aphids in Homoptera, cabbage moths, cotton bollworms and asparagus caterpillars in Lepidoptera, thrips in Thysanoptera, acarids and other pests, and has obviously higher effect than a single agent.

Methoxyfenozide is a kind of of insect growth regulator, IGR, is mainly that the normal growth of interference insect is grown, though insect molting and dead, and can suppress to ingest.This product is strong to controlling object selectivity, is mainly used in the control of lepidoptera pest.
But diamond-back moth, cotton bollworm and thrips are under the condition of current long-term prescription, and resistance increases gradually, and agricultural chemicals single dose declines gradually to the effect of control of insect.Inventor finds after deliberation, and the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, not yet finds up to now the Pesticidal combination of relevant chlopyrifos and methoxyfenozide.
Summary of the invention
The compound pesticide compositions that the object of this invention is to provide a kind of containing chlopyrifos and methoxyfenozide, this Pesticidal combination is the multifunctional insecticide composition of preventing and treating in resistance Homoptera, Lepidoptera, Semiptera, coleoptera, Hymenoptera, diptera, thrips and mite class any one or various pests.
Another object of the present invention is to provide this compound pesticide compositions and prevents and treats in resistance Homoptera, Lepidoptera, Semiptera, coleoptera, Hymenoptera, diptera, thrips and mite class the application on the insecticidal materials of any one or various pests in preparation, the particularly application on the insecticidal materials of any one or various pests in preparation control rice fulgorid, aphid, diamond-back moth, cotton bollworm, beet armyworm, thrips and mite class.
The object of the invention is to be achieved through the following technical solutions:
A compound pesticide compositions for containing chlopyrifos and methoxyfenozide, it is main active ingredient that this Pesticidal combination be take chlopyrifos and methoxyfenozide, wherein, the weight ratio of chlopyrifos and methoxyfenozide is 0.1 ~ 80:0.5 ~ 80.Be preferably 0.5 ~ 50:2 ~ 50, more preferably 0.5 ~ 10:4 ~ 30.In this Pesticidal combination, effective ingredient is present in composition with synergy effective dose.
In compound pesticide compositions of the present invention, the two weight percentage in this compound pesticide compositions of chlopyrifos and methoxyfenozide is 3% ~ 80%.Be preferably 5% ~ 55%, most preferably 10% ~ 40%.
Compound pesticide compositions of the present invention be take chlopyrifos and methoxyfenozide and is mixed with any one formulation allowing on agricultural chemicals, the preferred missible oil of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion or water dispersible granules as main active ingredient and insecticides adjuvant and excipient.
Auxiliary agent can adopt calcium dodecyl benzene sulfonate, agriculture breast 600#, the rare block compound of polyoxyethylene polyoxy third (as agriculture breast 33
#), polyoxyethylene nonylphenol ether etc., excipient comprises cyclohexanone, solvent naphtha, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can alone or and use.
The compound pesticide compositions of containing chlopyrifos of the present invention and methoxyfenozide is prevented and treated in resistance Homoptera, Lepidoptera, Semiptera, coleoptera, Hymenoptera, diptera, thrips and mite class the application on the insecticidal materials of any one or various pests in preparation.Especially in preparation control rice fulgorid, aphid, diamond-back moth, cotton bollworm, beet armyworm, thrips and mite class, the effect in the insecticidal materials of any one or various pests is the most remarkable.And suppress insect the pesticide resistance of unitary agent (chlopyrifos or methoxyfenozide are arbitrary) is produced.
Beneficial effect of the present invention compared with prior art:
(1) compare with single dose, said composition antagonism lepidoptera pest, as diamond-back moth and thrips insect thrips etc. has obvious synergistic function, overcomes and has delayed pest resistance to insecticide, expanding prevention spectrum, and desinsection speed is fast, has obviously improved control efficiency; (2) reduce control recruitment, drug cost; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with methoxyfenozide single dose with chlopyrifos, produce and use cost reduction; (6) suppress lepidoptera pest, Homoptera, thrips and mite pest the resistance of agricultural chemicals is strengthened, its successful is used higher than its single dose.
