Abstract

The invention discloses a synergistic insecticidal composition containing dinotefuran and acetamiprid and an application thereof. The synergistic insecticidal composition takes the dinotefuran and the acetamiprid as main active ingredients, wherein the weight ratio of the dinotefuran to the acetamiprid is (0.1-80):(0.1-70). The insecticidal composition can be used for controlling homoptera, hemiptera and coleoptera pests, in particular to plant hoppers, whiteflies, leafhoppers and aphids on the crops, generate the higher synergy, overcome and stay the drug resistance of the pests, realize long desinsection speed and long lasting period and reduce the medicament cost; and furthermore, the effects of the insecticidal composition are obviously higher than a single agent.

Description

A kind of Synergistic insecticidal compositions and application thereof that contains MTI-446 and Acetamiprid
Technical field
The invention belongs to pesticide field, being specifically related to a kind of is the Synergistic insecticidal compositions and the application thereof of main active ingredient with MTI-446 and Acetamiprid.
Background technology
MTI-446 (dinotefuran) is the third generation nicotinic insecticide of Mitsui chemical company exploitation.The chemical constitution of itself and existing nicotinic insecticide is far from each other, and chloro-pyridine base, chloro thiazolyl before its tetrahydrofuran base has replaced do not contain the halogen family element.Simultaneously, also different at aspect of performance with nicotine.So people are referred to as " furans nicotine " at present.The MTI-446 chemical name: 1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine, structural formula is following:
A new generation's anabasine insecticide MTI-446 mainly acts on insect neurotransmission system, makes the insect paralysis dead.This medicament insecticidal spectrum is wide, has remarkable interior suction osmosis, and has promptly shown very high insecticidal activity at very low dosage.This medicament is fool proof to mammal, birds and aquatile, and crop is not had poisoning, can be used for numerous crops such as paddy rice, fruit tree, vegetables.To rice grub brown planthopper, white-backed planthopper, small brown rice planthopper, rice leafhopper, rice spider rafter stinkbug, star stinkbug, green rice bug resemble, red must fleahopper, rice negatively mixes worm, rice tube water snout moth's larva is efficient.Effective to striped rice borer, oryza chinensis class.Efficient to vegetables, fruit insect Phytophthira, aleyrodid class, a red-spotted lizard class, unaspis shield kuwana, the green stinkbug of Zhu, peach fruit borer, tangerine lyonetid, the thin moth of tea, striped flea-beetle, the beans fly of diving.The cured a red-spotted lizard in diagonal angle, diamond-back moth, two secret notes are chrysomelid, tea golden thistle horse, onion thrips, golden thistle horse, oranges and tangerines golden thistle horse, soybean pod gall-midge, tomato Liriomyza are effective.MTI-446 has very wide insecticidal spectrum, and fool proof again to crop, people and animals and environment, is equipped with the method for using of various uses again, this agricultural chemicals large-tonnage agricultural chemicals that is expected to become international.
Acetamiprid (Acetamiprid) is a second generation anabasine insecticidal materials, chemical name N-(N-cyanic acid-ethyleneimine base)-N-methyl-2-chloropyridine-5-methylamine.Structural formula is following:
Acetamiprid acts on the insect nAChR.This medicine not only in absorption strong, wide, the active height of insecticidal spectrum and speed of action is fast, the lasting period is long.The antagonism insect is also effective.Can be used to prevent and treat homoptera pest such as aphid, plant hopper, aleyrodid, leafhopper etc.Under RD, to safety such as most of crops such as wild cabbage, Chinese cabbage, tea tree, tobacco, radish, no poisoning, less to the influence of wildlifes such as honeybee.
Homoptera and coleopteran pest are under the condition of present long-term prescription; Resistance increases gradually; The agent of agricultural chemicals list descends to the effect of control of insect gradually; Discover through the inventor, but the synergistic complex expanding prevention of agricultural chemicals is composed and the raising preventive effect, do not find the Pesticidal combination of relevant MTI-446 and Acetamiprid up to now as yet.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic insecticidal compositions that contains MTI-446 and Acetamiprid.
Another object of the present invention provides said composition and prevents and treats the application on the insecticidal materials of resistance Homoptera, coleopteran pest in preparation.
For achieving the above object, the present invention is composite with MTI-446 and Acetamiprid, obtains new and effective multifunctional insecticide composition.This insecticidal materials has good preventive effect to Homoptera and the coleopteran pest that plant hopper, aleyrodid, leafhopper and aphid etc. are easy to generate resistance; And the inhibition insect is to the pesticide resistance generation of single preparation (MTI-446 or Acetamiprid are arbitrary).
The objective of the invention is to realize through following technical scheme:
A kind of Synergistic insecticidal compositions that contains MTI-446 and Acetamiprid is characterized in that it is main active ingredient with MTI-446 and Acetamiprid, and wherein, the weight ratio of MTI-446 and Acetamiprid is 0.1～80: 0.1～70.The weight ratio of MTI-446 and Acetamiprid preferred 5～50 in this Synergistic insecticidal compositions: 2～60, further be preferably 5～20: 1～20.
In the present composition, the two percentage by weight that accounts for composition of MTI-446 and Acetamiprid is 1～80%.Be preferably 5～50%, most preferably 5～40%.The effective ingredient of above-mentioned desinsection combination is present in the composition with the synergy effective dose." % " of the present invention is mass percent.
Above-mentioned desinsection combination is that main active ingredient (active component) and insecticides adjuvant, excipients are mixed with any one formulation that allows on the agricultural chemicals with MTI-446 and Acetamiprid.Be preferably missible oil, suspending agent, aqueous emulsion, wetting powder, microemulsion and water dispersion granule.
Said auxiliary agent can adopt calcium dodecyl benzene sulfonate, APES, polyoxyethylene polyoxy third rare block compound (like farming breast 33 #), the one or more combinations in the NPE, excipient comprises cyclohexanone, solvent naphtha, solvent naphtha, water, pyrrolidones, dimethyl formamide, dimethyl sulfoxide (DMSO), antifreezing agent (like propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can singly be used or mix and use.
Above-mentioned Pesticidal combination can be used in preparation prevents and treats the insecticidal materials of resistance Homoptera, Semiptera, coleopteran pest; The control efficiency of the present composition is used apparently higher than its single agent, and described homoptera pest can refer in particular to plant hopper, aleyrodid, leafhopper and aphid.
Show through indoor synergism test mensuration: composite dose all has significant synergistic insecticidal action; 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: compare with single agent, said composition has notable synergistic to insect, has obviously improved control efficiency; One medicine is controlled more, and a dispenser can prevent and treat various pests simultaneously, reduces control recruitment cost; Alternative high-toxic pesticide, and reduce the field dosage significantly, effectively reduce environmental pollution and residue of pesticide; Have concurrently quick-acting and long-acting; Compare with the agent of MTI-446 list, produce and the use cost reduction; Suppress the resistance enhancing of insect to agricultural chemicals.
