Abstract
The invention discloses a synergistic insecticidal composition containing dinotefuran and clothianidin, and an application thereof. The synergistic insecticidal composition employs dinotefuran and clothianidin as main effective components, wherein a weight ratio of dinotefuran to clothianidin is 1-80 : 1-70. The insecticidal composition can produce a relatively high synergistic interaction effect, overcomes or delays pest resistance, has fast insecticidal speed and long efficacy duration and reduces pesticide cost. The insecticidal composition can be used for preventing hemiptera pests and lepidoptera pests, is particularly suitable for preventing plant hopper, aleyrodid, leafhopper and aphid, and has an effect obviously higher than that of a single dosage.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions and application thereof take MTI-446 and clothianidin as main active ingredient.
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 with nicotine at aspect of performance.So people are referred to as " furans nicotine " at present.MTI-446 chemical name: 1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine.
A new generation's anabasine insecticide MTI-446 Main Function makes the insect paralysis dead in insect neurotransmission system.This medicament insecticidal spectrum is wide, has remarkable interior sorptivety and thoroughly acts on, and namely shown very high insecticidal activity at very low dosage.This medicament is fool proof to mammal, birds and aquatile, and crop without poisoning, be 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, the negative mixed worm of rice, rice cylinder water snout moth's larva be 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 using method of various uses again, this agricultural chemicals large-tonnage agricultural chemicals that is expected to become international.
Clothianidin (Clothianidin) belongs to anabasine insecticide, and sterling is white crystalline powder, 176.8 ℃ of fusing points, chemical name (E)-1-(2-chloro-1,3-thiazoles-5-ylmethyl)-3-methyl-2-nitroguanidine.
Clothianidin be a kind of active high, have interior absorption, tag and the broad spectrum pesticide of stomach poison function.The mechanism of action is in conjunction with the nAChR that is positioned at neural post-synapse.Be applicable to foliar spray, soil treatment effect.Show to have greater activity and better control efficiency through indoor toxicity test to trialeurodes vaporariorum with to the field control effectiveness test of tomato Bemisia tabaci.Show preferably quick-acting, the lasting period is about 7 days.Be mainly used in paddy rice, vegetables, fruit tree and other crop, control Semiptera, coleoptera, diptera and some lepidoptera pest.
Rice fulgorid and aphid are under the condition of present long-term prescription, resistance increases gradually, the agricultural chemicals single dose descends gradually to the effect of control of insect, study discovery through the inventor, 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 MTI-446 and clothianidin.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic insecticidal compositions that contains MTI-446 and clothianidin.
Another object of the present invention provides said composition and prevents and treats application on the insecticidal materials of resistance Semiptera, coleopteran pest in preparation.
For achieving the above object, MTI-446 and clothianidin that the present invention will grow the lasting period are composite, obtain new and effective multifunctional insecticide composition.This insecticidal materials has good preventive effect to Semiptera and the coleopteran pest that plant hopper, aleyrodid, leafhopper and aphid etc. produce resistance easily; And suppress insect to the pesticide resistance generation of unitary agent (MTI-446 or clothianidin are arbitrary).
The objective of the invention is to be achieved through the following technical solutions:
A kind of Synergistic insecticidal compositions that contains MTI-446 and clothianidin is characterized in that it take MTI-446 and clothianidin as main active ingredient, and wherein, the weight ratio of MTI-446 and clothianidin is 1～80: 1～70.The weight ratio of MTI-446 and clothianidin preferred 1～50 in this Synergistic insecticidal compositions: 1～60, more preferably 1～20: 1～20.
In the present composition, the two percentage by weight that accounts for composition of MTI-446 and clothianidin is 1～80%.Be preferably 5～50%, most preferably 5～40%.The effective ingredient of above-mentioned Insecticidal combinations is present in the composition with the synergy effective dose." % " of the present invention is mass percent.
Above-mentioned Insecticidal combinations is take MTI-446 and clothianidin 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 can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (such as farming breast 33
#), the one or more combinations in the polyoxyethylene nonylphenol ether, excipient comprises isopropyl alcohol, solvent naphtha, solvent naphtha, water, pyrrolidones, dimethyl formamide, dimethyl sulfoxide (DMSO), antifreezing agent (such as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can alone or and usefulness.
Above-mentioned Pesticidal combination can be prevented and treated application in the insecticidal materials of resistance Semiptera, coleopteran pest 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 plant hopper, aleyrodid, leafhopper and aphid.
Show through indoor synergism test mensuration: built agent all has significant synergistic insecticidal action; Field control effectiveness test shows that equally also all built agents of the present invention all are significantly higher than the effect of corresponding single dose agricultural chemicals to the insecticidal effect of water rice hopper and wheat aphid.
Pesticidal combination of the present invention compared with prior art, produce following beneficial effect: (1) is compared with single dose, 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 significantly reduce the field dosage, effective environmental contamination reduction and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with the MTI-446 single dose, produce and the use cost reduction; (6) suppress insect to the resistance enhancing of agricultural chemicals.
