Abstract
The invention discloses a synergistic pesticide combination containing nitenpyram and pyridalyl and an application of the combination. The synergistic pesticide combination uses nitenpyram and pyridalyl as main active components, wherein the weight ratio of the nitenpyram to the pyridalyl is (0.1-80):(0.2-70). The pesticide combination can produce higher synergistic effect, overcomes and delays pesticide resistance of pests, has high pest control speed and long persisting efficacy and lowers the application cost. The invention can be used to prevent and control paddy delphacidae, aleyrodidae,aphides and other hemipteran pests generated on crops, and the resulting effect is apparently higher than that obtained by using a single agent.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions and application thereof take Nitenpyram and pyridalyl as main active ingredient.
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 in anti-ly on agricultural and the gardening eliminate aphis, the insects such as leafhopper, thrips, plant hopper, toxicity is low, lasting medicine to crop without poisoning, use safety; This medicine acts on nAChR, and mode is unique, and insect is difficult for producing resistance, and remarkable interior suction and osmosis are arranged.
Pyridalyl (pyridalyl), chemical name 2,6-two chloro-4-(3,3-, two chloroallyloxyaminos) phenyl 3-[5-(trifluoromethyl-2 hydroxy pyrimidine) propyl group] ether.Structural formula is as follows:
Pyridalyl has simultaneously tags and stomach poison function, and the larva of lepidoptera pest main in the agricultural production is had very high insecticidal activity.In addition, pyridalyl also demonstrates good insecticidal activity to thrips and dipterous insect, and is opposite with its high activity, and pyridalyl is very low to various useful arthropodan toxicity.
The Semiptera such as rice fulgorid, aphid insect is under the condition of present long-term prescription, and resistance increases gradually, and the agricultural chemicals single dose descends gradually to the effect of control of insect, there is no effective preparation for the control of Semiptera insect.The inventor finds after deliberation, and the composite of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, finds not yet that up to now the complex insecticidal composition of relevant Nitenpyram and pyridalyl is used for preventing and treating resistance Semiptera insect.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic insecticidal compositions that contains Nitenpyram and pyridalyl.
Another object of the present invention provides above-mentioned Synergistic insecticidal compositions and prevents and treats application in the resistance Semiptera insect insecticidal materials in preparation.
For achieving the above object, two kinds of insecticidal materials Nitenpyrams and pyridalyl that the present invention is different with controlling object are composite, obtain the new and effective multifunctional insecticide composition of a class.This Pesticidal combination has good preventive effect to the various pests that rice fulgorid, aphid, diamond-back moth easily produce resistance; And suppress insect to the pesticide resistance generation of unitary agent (Nitenpyram or pyridalyl).
The present invention adopts following technical scheme:
A kind of Synergistic insecticidal compositions that contains Nitenpyram and pyridalyl is characterized in that this Synergistic insecticidal compositions take Nitenpyram and pyridalyl as main active ingredient, and wherein, the weight ratio of Nitenpyram and pyridalyl is 0.1～80: 0.2～70.
The weight ratio of Nitenpyram and pyridalyl preferred 0.5～60 in this Synergistic insecticidal compositions: 2～50, more preferably 1～30: 4～20.
In the present composition, the two percentage by weight that accounts for composition of Nitenpyram and pyridalyl is 3～80%.Be preferably 5～50%, most preferably 5～20%." % " of the present invention is mass percent.
Above-mentioned Insecticidal combinations is take Nitenpyram and pyridalyl as main active ingredient (active component), and insecticides adjuvant, excipients are mixed with any one formulation that allows on the agricultural chemicals.Be preferably missible oil, suspending agent, aqueous emulsion, wetting powder, microemulsion and water dispersion granule.
Described auxiliary agent specifically can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (such as farming breast 33
#), polyoxyethylene nonylphenol ether etc., excipient can adopt cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Auxiliary agent, excipient can alone or mixing and usefulness, also can add other auxiliary material that allows on the pesticidal preparations.
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 dose, and described Semiptera insect refers in particular to rice fulgorid, aphid, aleyrodid.
Indoor bioassay and field control effectiveness test show that compound insecticidal medicine of the present invention has significant synergistic insecticidal action to the Semiptera insect, all is significantly higher than the effect of corresponding single dose agricultural chemicals especially to the insecticidal effect of water rice hopper, aphid, aleyrodid.
Beneficial effect of the present invention: the Nitenpyram that provides of the present invention and pyridalyl Pesticidal combination, can produce higher synergistic function, desinsection speed is fast, overcome and delayed pest resistance to insecticide, the expanding prevention spectrum has reduced drug cost simultaneously, and its successful is higher than its single dose to be used.
Embodiment
Embodiments of the invention are the methods that adopt indoor bioassay and field trial to combine.First 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 again field trial.
