Abstract
The invention discloses a synergistic insecticidal composition containing tolfenpxrad and flonicamid and an application thereof. The insecticidal composition takes the tolfenpxrad and the flonicamid as main active ingredients, wherein the weight ratio of the tolfenpxrad to the flonicamid is (0.1-80):(0.5-80). The insecticidal composition has the effects of expanding a control spectrum and realizing synergy, can reduce the cost of medication, can be prepared into missible oil, wettable powder, micro-emulsion, aqueous emulsion, suspension and water dispersible granules, and can be used for controlling lepidoptera, homoptera, hymenoptera, thysanoptera or coleoptera and other various pests.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions and the application thereof that contain Tolfenpyrad and flonicamid.
Background technology
Tolfenpyrad (Tolfenpyrad), the chloro-3-ethyl of chemical name: 4--1-methyl-N-{ [4-(4-methylphenoxy) phenyl]-methyl }-1H pyrazoles-5-carboxylic acid amides, for off-white color pressed powder, density (25 DEG C): 1.18g/cm, vapour pressure (25 DEG C): < 5 × 10Pa.Solvability (25 DEG C): water 0.037mg/L, n-hexane 7.41g/L, toluene 366g/L, methyl alcohol 59.6g/L.Distribution coefficient (n-octyl alcohol/water) (25 DEG C): log Pow 5.61.Structural formula is:
The acute toxicity of Tolfenpyrad preparation is: rat oral LD
50102 (heros), 83 (female) mg/kg; Its mouse oral LD
50104 (heros), 108 (female) mg/kg.Acute dermal toxicity is relatively low, to rat, mouse LD
50equal > 2000mg/kg.Moderate spread effect is had to lagophthalmos eyeball and skin.
The novel pyrazole heterocyclic insecticidal/acaricidal agent that Tolfenpyrad Shi Yuan Mitsubishi chemical company (its agricultural chemicals part now belongs to Japanese agricultural chemicals company) develops, its main mechanism is the oxidative phosphorylation stoping insect, also has ovicidal, presses down food, oviposition deterrence and bactericidal action.
Flonicamid (flonicamid), chemical name: N-cyanogen methyl-4-(trifluoromethyl) vitamin PP, structural formula is:
Flonicamid is effective to various sucking pest, and has good osmosis.It can from root to stem, the infiltration of leaf portion, but relatively weak to stem, root osmosis by leaf portion.This medicament causes effect by hindering insect act of sucking.Insect is taken in after medicament and stops very soon sucking, last hungry and dead.Insect according to electronics sucks behavior (EMIII) and resolves, and this agent can make the lancet tissue of the sucking property insects such as aphid insert plant tissue and to cause effect.
Containing the insecticide variety of single component often existing defects in agricultural chemicals control of insect: use is easily developed immunity to drugs continuously, and insecticidal spectrum is narrow, and can not provide comprehensive protection for crop, peasant's drug cost is high.Above-mentioned shortcoming can be overcome to a certain extent to a certain extent by two kinds or being combined in of two or more active component.There is two kinds of synergistic effect or the combination mixture of two or more active component, can preventive effect be improved, reduce active ingredient ground dosage, cost-saving, slow down pest resistance and to occur and can expanding prevention spectrum, play that many worms are double to be controlled, reduce the use cost of peasant.
Summary of the invention
The object of this invention is to provide a kind of Synergistic insecticidal compositions containing Tolfenpyrad and flonicamid, said composition can be used for preventing and treating various agricultural insect, such as control paddy rice rice leaf roller or vegetable aphid and thrips etc., the effect that a drug prevents and treats dissimilar insect can be reached.
The Synergistic insecticidal compositions that another object of the present invention is to provide containing Tolfenpyrad and flonicamid is preparing the application in insecticidal materials.
The present invention adopts following technical scheme:
Containing a Synergistic insecticidal compositions for Tolfenpyrad and flonicamid, it is with Tolfenpyrad and flonicamid for principle active component, and wherein, the weight ratio of Tolfenpyrad and flonicamid is 0.1 ~ 80: 0.5 ~ 80.Be preferably 1 ~ 60: 1 ~ 70, more preferably 1 ~ 30: 1 ~ 30.The effective ingredient of above-mentioned Insecticidal combinations is present in composition with enhancing effective amount.
At the Synergistic insecticidal compositions containing Tolfenpyrad and flonicamid of the present invention, Tolfenpyrad is 2% ~ 80% with the weight percentage both flonicamid in this Synergistic insecticidal compositions, preferably 8% ~ 60%, and optimum is 20% ~ 40%.
The above-mentioned Synergistic insecticidal compositions containing Tolfenpyrad and flonicamid with Tolfenpyrad and flonicamid for principle active component (active component) and insecticides adjuvant, excipients are mixed with any one formulation that agricultural chemicals allows.The preferred microemulsion of formulation, aqueous emulsion, wetting powder, suspending agent, missible oil and water dispersion granule.
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, cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent and other agriculturally known auxiliary material can be alone or and use.
The above-mentioned Synergistic insecticidal compositions containing Tolfenpyrad and flonicamid is preparing the application in the insecticidal materials preventing and treating one or more insects in Lepidoptera, Homoptera, Hymenoptera thrips or coleoptera.Especially the effect in the insecticidal materials of preparation control paddy rice rice leaf roller or vegetable aphid, aleyrodid, leafhopper or thrips is remarkable.
Synergistic insecticidal compositions antagonism Lepidoptera of the present invention, Thysanoptera have significant preventive effect, especially have good preventive effect for the easy various pests producing resistance such as paddy rice rice leaf roller or thrips; And suppress insect produce the pesticide resistance of unitary agent (Tolfenpyrad or flonicamid) and homoptera pest can be prevented and treated as vegetable aphid, aleyrodid, leafhopper etc. simultaneously.
Pesticidal combination of the present invention compared with prior art, produces following beneficial effect: (1), compared with single dose, said composition insect has obvious Synergistic, significantly improves 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) compared with Tolfenpyrad single dose, produce and use cost reduction; (6) insect is suppressed to strengthen the resistance of agricultural chemicals;
