Abstract

The invention discloses a nitenpyram and chlorpyrifos methyl contained synergia insecticidal composite and an application thereof. In the insecticidal composite, nitenpyram and chlorpyrifos methyl are taken as active constituents, wherein the weight ratio of the nitenpyram and chlorpyrifos methyl is (0.1-80):(0.5-80). In the insecticidal composite, high synergism can be generated, drug resistance of injurious insect is overcome and delayed, prevention and control spectrum are expanded, the insecticidal speed is rapid, and the medication cost is reduced and toxicity is alleviated. The nitenpyram and chlorpyrifos methyl contained synergia insecticidal composite can prevent and control hemiptera injurious insects on crops, is particularly used for preventing and controlling plant hoppers and wheat aphids of rice, and the effect of the composite is obviously better than that of siple dosage.

Description

A kind of Synergistic insecticidal compositions that contains Nitenpyram and chlorpyrifos-methyl and uses thereof
Technical field
The invention belongs to pesticide field, be specifically related to a kind ofly be the Pesticidal combination of main active and answer purposes with Nitenpyram and chlorpyrifos-methyl.
Background technology
Nitenpyram (nitenpyram) belongs to the anabasine insecticidal materials, and chemical name is (E) N-(6-chloro-3 pyridylmethyls)-N-ethyl-N '-methyl-2-nitro ethenylidene diamines.Structural formula is as follows:
This medicine insecticidal spectrum is wide, be widely used on agricultural and the gardening prevent eliminating aphis, Semiptera insects such as leafhopper, thrips, plant hopper, consumption is few, toxicity is low, lasting medicine does not have poisoning, safe in utilization to crop; This medicine acts on nAChR, the mode uniqueness, and insect is difficult for producing resistance, and remarkable interior suction and osmosis are arranged, and market prospects are comparatively wide, but its commercially available price is higher.
Chlorpyrifos-methyl (Chlorpyrifos-methyl) chemical name is: O, O-dimethyl-O-(3,5, the 6-trichloro-2-pyridyl) thiophosphate.Chlorpyrifos-methyl is a kind of broad spectrum insecticide medicine, by tag, stomach toxicity and stifling mode be all effective, absorption in not having, it is used for preventing and treating insect and various leaf class pest on crop on aquatic larva, fly, sanitary insect pest, mosquito (adult), the warehousing cereal.But this insecticide is longer service time at present, and many insects increase its resistance.
The Semiptera insect increases gradually in present resistance, and the agent of agricultural chemicals list descends gradually to the effect of control of insect.The inventor finds after deliberation, and the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, up to now as yet not about the Pesticidal combination of Nitenpyram and chlorpyrifos-methyl.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic insecticidal compositions that contains Nitenpyram and chlorpyrifos-methyl.This Pesticidal combination can produce higher cooperative synergism, and overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, reduces drug cost, alleviates toxicity
Another object of the present invention provides this desinsection and is combined in the application that prevents and treats on the resistance Semiptera insect.
For achieving the above object, Nitenpyram and chlorpyrifos-methyl that the present invention will grow the lasting period are composite, obtain the new and effective multifunctional insecticide composition of a class.This insecticidal materials has good preventive effect to the various pests that rice fulgorid and wheat aphid are easy to generate resistance; And the inhibition insect is to the pesticide resistance generation of unitary agent (Nitenpyram or chlorpyrifos-methyl).
The present invention adopts following technical scheme:
A kind of Synergistic insecticidal compositions that contains Nitenpyram and chlorpyrifos-methyl is characterized in that it is an active ingredient with Nitenpyram and chlorpyrifos-methyl, and wherein, the weight ratio of Nitenpyram and chlorpyrifos-methyl is 0.1~80: 0.5~80.The effective ingredient of above-mentioned desinsection combination is present in the composition with the synergy effective dose.
The weight ratio of Nitenpyram and chlorpyrifos-methyl preferred 0.5~50 in this Synergistic insecticidal compositions: 1~70, more preferably 0.5~30: 1~60.
In the present composition, the two percentage by weight that accounts for composition of Nitenpyram and chlorpyrifos-methyl is 1~85%.Be preferably 1~60%, most preferably 10~40%.
The combination of above-mentioned desinsection is mixed with any one formulation that allows on the agricultural chemicals with Nitenpyram and chlorpyrifos-methyl (active component) and known insecticides adjuvant, excipients.Be preferably missible oil, suspending agent, aqueous emulsion, wetting powder, microemulsion and water dispersion granule.
Described auxiliary agent can adopt alkylphenol polyoxyethylene disodium sulfosuccinate, N-Methyl pyrrolidone, phenethyl phenol polyethenoxy ether, calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (as farming breast 33 #), polyoxyethylene nonylphenol ether, tributyl phosphate, aluminium-magnesium silicate, borax, kaolin etc., excipient comprise ethylene glycol, cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), water etc.Above auxiliary agent, excipient and other auxiliary material can singly be used or and use.
Above-mentioned Pesticidal combination can be prevented and treated application in the insecticidal materials of resistance Semiptera insect in preparation, and the control efficiency of the present composition is used apparently higher than its single agent, and described Semiptera insect refers in particular to rice hoppers and wheat aphid.
Measure through indoor synergism test and to show: water rice hopper and wheat aphid are all had significant synergistic insecticidal action by composite dose of Nitenpyram and chlorpyrifos-methyl; Field control effectiveness test equally also shows the composite dose of effect that the insecticidal effect of water rice hopper and wheat aphid all is significantly higher than corresponding single agent agricultural chemicals that the present invention is all.
Pesticidal combination of the present invention compared with prior art produces following beneficial effect: (1) is compared with single agent, and said composition has notable synergistic to insect, 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 the agent of Nitenpyram list, produce and the use cost reduction; (6) suppress the resistance enhancing of insect to agricultural chemicals.
