Abstract
The invention discloses a synergistic pesticidal composition containing nitenpyram and ethofenprox and an application thereof. The synergistic pesticidal composition adopts the nitenpyram and the ethofenprox as the main active ingredients, wherein the weight ratio of the nitenpyram to the ethofenprox is (0.1-80): (0.1-60). The synergistic pesticidal composition containing the nitenpyram and the ethofenprox can be used for preventing and controlling resistant hemiptera injurious insects, and has obviously preventing and controlling effect on wheat aphids and rice planthopper. The pesticidal composition can generate higher synergy, overcomes and delays the drug resistance of the injurious insects, and has the advantages of fast insecticidal speed and long residual activity; and by using the synergistic pesticidal composition, the pesticide cost is reduced, and the prevention and control effect is obviously superior to that of the single dosage.
Description
Technical field
The invention belongs to pesticide field, being specifically related to a kind of is the Pesticidal combination and the application thereof of main active with Nitenpyram and ether chrysanthemum ester.
Background technology
Nitenpyram (nitenpyram), chemical name are (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, leafhopper, thrips, Semiptera insect, 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.
Ether chrysanthemum ester (etofenprox) is a kind of pyrethoid insecticides thing, has that insecticidal spectrum is wide, insecticidal activity is high, knocks down that speed is fast, the lasting period is long, less to natural enemy lethality such as paddy field spiders, to characteristics such as crop safeties.Be applicable to control paddy rice, vegetables, cotton, effective to various pests such as Lepidoptera, Semiptera, orthoptera, coleoptera, diptera and Isopteras.But it is, invalid to the acarid control because ether chrysanthemum ester is not inhaled conduction in insect is had.And it is longer that this insecticide is used the time, and many insects are single with having produced pesticide resistance and drug resistance in various degree to it.
The Semiptera insect as aphid, plant hopper, leafhopper etc., 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 ether chrysanthemum ester.
Summary of the invention
But the Synergistic insecticidal compositions that contains Nitenpyram and ether chrysanthemum ester that the purpose of this invention is to provide a kind of high-efficiency prevention and control resistance Semiptera insect, this Pesticidal combination production cost is low, have quick-acting and the long-acting pesticidal effect.
Another object of the present invention provides this desinsection and is combined in the application for preparing on the insecticidal materials of preventing and treating resistance Semiptera insect.
The objective of the invention is to be achieved through the following technical solutions:
A kind of Synergistic insecticidal compositions that contains Nitenpyram and ether chrysanthemum ester, this Synergistic insecticidal compositions is main active ingredient with Nitenpyram and ether chrysanthemum ester, wherein, the weight ratio of Nitenpyram and ether chrysanthemum ester is 0.1～80: 0.1～60.
The weight ratio preferred 0.5～60: 0.2～40 of Nitenpyram and ether chrysanthemum ester in this Synergistic insecticidal compositions, more preferably 1～40: 1～30.
In the present composition, the two percentage by weight that accounts for composition of Nitenpyram and ether chrysanthemum ester is 3～80%.Be preferably 5～55%, most preferably 5～30%.Effective ingredient is present in the composition with the synergy effective dose in this Pesticidal combination.
This Pesticidal combination is that main active ingredient and insecticides adjuvant, excipients are mixed with any one formulation that allows on the agricultural chemicals with Nitenpyram and ether chrysanthemum ester, and described formulation is preferably missible oil, aqueous emulsion, microemulsion or suspending agent.
Described auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (as farming breast 33
#), the one or more combinations in the polyoxyethylene nonylphenol ether, excipient comprises cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can singly be used or and use.
The above-mentioned Synergistic insecticidal compositions that contains Nitenpyram and ether chrysanthemum ester is being prevented and treated resistance Semiptera insect, especially anti-eliminate aphis and plant hopper on application in significant effect is all arranged.
The present invention makes full use of both mutual supplement with each other's advantages by the network analysis to Nitenpyram and ether chrysanthemum ester insecticidal properties, and Nitenpyram and ether chrysanthemum ester is composite according to certain ratio.Insecticidal materials of the present invention has good preventive effect to the Semiptera insect that aphid, plant hopper, leafhopper etc. are easy to generate resistance; And the inhibition insect is to the pesticide resistance generation of unitary agent (Nitenpyram or ether chrysanthemum ester).Its effect is used apparently higher than its single agent.
Pesticidal combination of the present invention compared with prior art, produce following beneficial effect: the present invention contains the Pesticidal combination of Nitenpyram and ether chrysanthemum ester, can produce higher cooperative synergism, overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, and the lasting period is long, reduced drug cost, control efficiency is used apparently higher than its single agent.The present invention especially can be used for preventing and treating the wheat aphid and the rice hoppers of high resistance.
