Abstract
The invention belongs to the field of agricultural chemicals and discloses a synergistic insecticidal composition containing tolfenpxrad and S-fenvalerate and an application thereof. The insecticidal composition takes the tolfenpxrad and the S-fenvalerate as main active ingredients, wherein the weight ratio of the tolfenpxrad to the S-fenvalerate 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 preparing insecticidal medicaments for controlling lepidoptera, homoptera, hymenoptera, 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 S-sumicidin.
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 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.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.
S-sumicidin (esfenvalerate), has another name called to come good fortune spirit, termite spirit, chemical name: S-alpha-cyano-3-phenoxy benzyl (S)-2 (4-chlorphenyl)-3 Methylbutanoic acid ester, and structural formula is:
S-sumicidin is the pyrethroid insecticides that a kind of activity is higher, only contains cis-isomer with sumicidin unlike it.But biocidal activity exceeds about 4 times than sumicidin, and thus using dosage is low.
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.Being combined in and can overcoming above-mentioned shortcoming to a certain extent to a certain extent by two kinds or various active component in the coming year.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 S-sumicidin, said composition can be used for preventing and treating various agricultural insect, such as control vegetables diamond-back moth, cabbage caterpillar, can also be used for preventing and treating cotton cotton bollworm, beet armyworm and onion 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 S-sumicidin is preparing the application prevented and treated in the insecticidal materials of one or more insects in resistance Lepidoptera, Homoptera, Hymenoptera or coleoptera.
The present invention adopts following technical scheme:
A kind of Synergistic insecticidal compositions containing Tolfenpyrad and S-sumicidin, it is with Tolfenpyrad and S-sumicidin for principle active component, and wherein, the weight ratio of Tolfenpyrad and S-sumicidin 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 S-sumicidin of the present invention, Tolfenpyrad is 2% ~ 80% with the gross weight percentage composition both S-sumicidin in this Synergistic insecticidal compositions, preferably 8% ~ 60%, and optimum is 20% ~ 40%.
Described Synergistic insecticidal compositions with Tolfenpyrad and S-sumicidin for the auxiliaries that principle active component and agricultural chemicals allow becomes any one formulation.The preferred pulvis of described formulation, 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 etc., or cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent and other auxiliary materials agriculturally allowed can be alone or and use.
Application in the insecticidal materials of Synergistic insecticidal compositions of the present invention one or more insects in preparation control Lepidoptera, Homoptera, Hymenoptera, thrips or coleoptera, preferably prevent and treat the application in the insecticidal materials of one or more insects in cotton cotton bollworm, beet armyworm, onion thrips rice fulgorid or snout moth's larva in preparation, prevent and treat the application in the insecticidal materials of cotton bollworm and diamond-back moth particularly preferably in preparation.
Pesticidal combination of the present invention compared with prior art, produce following beneficial effect: (1) is compared with single dose, the control of said composition to Lepidoptera, Homoptera, Hymenoptera, thrips or coleopteran pest has obvious synergistic function, 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.
