Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions and application thereof that contains 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, be the 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, mouse LD50 all＞2000mg/kg.Lagophthalmos eyeball and skin there is moderate spread effect.
Tolfenpyrad is the novel pyrazole heterocyclic insecticidal/acaricidal agent of former 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), chemical name: 3-iodo-N '-(2-mesyl-1,1-dimethyl ethyl group-N-{4-[1,2,2,2-tetrafluoro-1-(trifluoromethyl) ethyl]-the 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, the property out of control release that causes storing calcium ion.It is the compound that acts on blue Buddhist nun's alkali (Ryanodine) acceptor of insect cell at present few in number.Lepidoptera pest there is the spectrum preventive effect, produces without cross resistance with existing insecticide, be suitable for very much the control that existing insecticide produces the insect of resistance.Larva there is very outstanding preventive effect, limited to the adult preventive effect, there is not ovicidal action.Slightly conduct by xylem after in the infiltration plant body.Resistance of rainwater washing against.
Often there is defective in the insecticide variety that contains single component in the agricultural chemicals control of insect: 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.Can overcome to a certain extent above-mentioned shortcoming by two kinds or being combined in to a certain extent of two or more active components.Have 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, save cost, slow down pest resistance occur, and can the expanding prevention spectrum, play that many worms are double to be controlled, reduce peasant's use cost.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic insecticidal compositions that contains Tolfenpyrad and fipronil bisamide.
Another object of the present invention provides the application of this Synergistic insecticidal compositions.
The present invention adopts following technical scheme:
A kind of Synergistic insecticidal compositions that contains Tolfenpyrad and fipronil bisamide, this Synergistic insecticidal compositions is take Tolfenpyrad and fipronil bisamide as main active ingredient, wherein, the weight ratio of Tolfenpyrad and fipronil bisamide is 0.1～80: 0.5～80, preferred 1～60: 1～70, further preferred 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 is preferred 2%～80%, and is further preferred 8%～60%, and particularly preferably 20%～40%.
The auxiliary agent that this Synergistic insecticidal compositions allows on take Tolfenpyrad and fipronil bisamide as main active ingredient and agricultural chemicals is mixed with any one formulation.
Described auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (such as farming breast 33
#), polyoxyethylene nonylphenol ether etc., excipient comprises cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Above auxiliary agent and the upper known auxiliary material of other agricultural can alone or and usefulness.
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 that contains 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 has good preventive effect for paddy rice rice leaf roller or the easy various pests that produces resistance such as cotton cotton bollworm and vegetables diamond-back moth; And suppress insect the pesticide resistance of unitary agent (Tolfenpyrad or fipronil bisamide) is produced and can prevent and treat simultaneously homoptera pest such as thrips, aleyrodid, leafhopper etc.
By the insecticidal materials of the described Synergistic insecticidal compositions preparation that contains Tolfenpyrad and fipronil bisamide 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, produce following beneficial effect: (1) is compared with single dose, the 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 the field dosage, effective environmental contamination reduction and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with the Tolfenpyrad single dose, produce and the use cost reduction; (6) suppress insect to the resistance enhancing of agricultural chemicals;
