Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions and application thereof containing Tolfenpyrad and fipronil bisamide.
Background technology
Tolfenpyrad (Tolfenpyrad), chemical name :-chloro-3-ethyl-1-methyl-N-{[4-(4-methylphenoxy) phenyl]-methyl }-1H pyrazoles-5-carboxylic acid amides, for off-white color pressed powder, density (25 ℃): 1.18g/cm, vapour pressure (25 ℃): < 5 * 10Pa.Solvability (25 ℃): water 0.037mg/L, n-hexane 7.41g/L, toluene 366g/L, methyl alcohol 59.6g/L.Distribution coefficient (n-octyl alcohol/water) (25 ℃): 1og Pow 5.61.Structural formula is:
The acute toxicity of Tolfenpyrad preparation is: rat oral LD50 102 (hero), 83 (female) mg/kg; Its mouse oral LD50104 (hero), 108 (female) mg/kg.Acute dermal toxicity is relatively low, to rat, the equal > 2000mg/kg of mouse LD50.Lagophthalmos eyeball and skin are had to moderate spread effect.
The novel pyrazole heterocyclic insecticidal/acaricidal agent of Tolfenpyrad Shi Yuan Mitsubishi chemical company (its agricultural chemicals partly now belong to Japanese agricultural chemicals company) exploitation, its main mechanism is the oxidative phosphorylation that stops insect, also has ovicidal, presses down food, oviposition deterrence and bactericidal action.
Fipronil bisamide (flubendiamide), the iodo-N ' of chemical name: 3--(2-mesyl-1,1-dimethyl ethyl group-N-{4-[1,2,2,2-tetrafluoro-1-(trifluoromethyl) ethyl]-O-tolyl } phthalamide, structural formula is:
Fipronil bisamide belongs to Novel ortho benzenedicarboxamide insecticides, activates calcium release channel in blue Buddhist nun's alkali recipient cell, causes the property out of control of storing calcium ion to discharge.It is at present few in number compounds that acts on blue Buddhist nun's alkali (Ryanodine) acceptor of insect cell.Lepidoptera pest is had to spectrum preventive effect, produce without cross resistance with existing insecticide, be suitable for very much the control that existing insecticide produces the insect of resistance.Larva is had to very outstanding preventive effect, limited to adult preventive effect, there is no ovicidal action.After in infiltration plant body, by xylem, slightly conduct.Resistance of rainwater washing against.
Often there is defect in the insecticide variety containing single component: use is easily developed immunity to drugs continuously, and insecticidal spectrum is narrow, can not provide comprehensive protection for crop, and peasant's drug cost is high in agricultural chemicals control of insect.By two kinds or being combined in to a certain extent of two or more active components, can overcome to a certain extent above-mentioned shortcoming.There is two kinds of synergistic effect or the combination of two or more active components and be mixed, can improve preventive effect, reduce active ingredient ground dosage, cost-saving, slow down pest resistance occur, and can expanding prevention spectrum, play that many worms are double to be controlled, reduce peasant's use cost.
Summary of the invention
The object of this invention is to provide a kind of Synergistic insecticidal compositions containing Tolfenpyrad and fipronil bisamide.
Another object of the present invention is to provide the application of this Synergistic insecticidal compositions.
The present invention adopts following technical scheme:
A kind of Synergistic insecticidal compositions containing Tolfenpyrad and fipronil bisamide, it is main active ingredient that this Synergistic insecticidal compositions be take Tolfenpyrad and fipronil bisamide, wherein, the weight ratio of Tolfenpyrad and fipronil bisamide is 0.1～80: 0.5～80, preferably 1～60: 1～70, further preferably 1～30: 1～30, particularly preferably 1: 1～12.
Wherein, the two gross weight percentage composition in this Synergistic insecticidal compositions of Tolfenpyrad and fipronil bisamide preferably 2%～80%, further preferably 8%～60%, particularly preferably 20%～40%.
This Synergistic insecticidal compositions be take the auxiliary agent that Tolfenpyrad and fipronil bisamide allow on main active ingredient and agricultural chemicals and is mixed with any one formulation.
Described auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, the rare block compound of polyoxyethylene polyoxy third (as agriculture breast 33
#), polyoxyethylene nonylphenol ether etc., excipient comprises cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent and the upper known auxiliary material of other agricultural can alone or and use.
Described formulation is missible oil, wetting powder, microemulsion, aqueous emulsion, suspending agent or water dispersion granule.
Application in the insecticidal materials of the above-mentioned Synergistic insecticidal compositions containing Tolfenpyrad and fipronil bisamide one or more insects in preparation control Lepidoptera, Homoptera, Hymenoptera or coleoptera.Especially the effect in the insecticidal materials of preparation control paddy rice rice leaf roller or cotton cotton bollworm and vegetables diamond-back moth is remarkable.
Synergistic insecticidal compositions antagonism lepidoptera pest of the present invention has significant preventive effect, especially for paddy rice rice leaf roller or the easy various pests that produces resistance such as cotton cotton bollworm and vegetables diamond-back moth, has good preventive effect; And suppress insect to the pesticide resistance generation of unitary agent (Tolfenpyrad or fipronil bisamide) and can prevent and treat homoptera pest as thrips, aleyrodid, leafhopper etc. simultaneously.
The insecticidal materials of being prepared by the described Synergistic insecticidal compositions containing Tolfenpyrad and fipronil bisamide is when preventing and treating resistance Lepidoptera, Hymenoptera or coleopteran pest, can prevent and treat again the special paddy rice rice leaf roller of homoptera pest or cotton cotton bollworm and vegetables diamond-back moth, reach the effect that a medicine is controlled more.
Pesticidal combination of the present invention compared with prior art, produces following beneficial effect: (1) is compared with single dose, and said composition insect has notable synergistic, 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 field dosage, effectively reduce environmental pollution and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with Tolfenpyrad single dose, produce and use cost reduction; (6) suppressing insect strengthens the resistance of agricultural chemicals;
