ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to pesticidal liquid compositions and pesticidal aerosol compositions.
BACKGROUND ART
It is known that 2-methoxycarbonyl-4-chlorotrifluoromethane-sulfonanilide can be used as an active ingredient of an insecticidal/acaricidal composition in Japanese Laid-open Patent Nos. sho-57-156407A and hei-8-319202A. However, its insecticidal/acaricidal effect may be insufficient when used as a formulation such as oil solution, aerosol and the like.
SUMMARY OF THE INVENTION
The present invention provides a composition comprising 2-methoxycarbonyl-4-chlorotrifluoromethanesulfonanilide of the formula:
and a saturated hydrocarbon having a specific carbon number which has an extremely good pesticidal activity and especially shows an excellent effect in a formulation of a pesticidal aerosol composition.
The pesticidal composition of the present invention comprises 2-methoxycarbonyl-4-chlorotrifluoromethanesulfonanilide (hereinafter referred to as Compound A) and a saturated hydrocarbon having 13 to 17 of carbon number. The pesticidal composition of the present invention can be a liquid composition which comprises 0.01 to 5% by weight of Compound A and 40 to 99.9% by weight of a saturated hydrocarbon(s) having 13 to 17 of carbon number. In other words, the pesticidal liquid composition of the present invention comprises Compound A and at least one saturated hydrocarbon having 13 to 17 of carbon number wherein the amount of Compound A is 0.01 to 5% by weight and the total amount of said saturated hydrocarbons is 35 to 99.9% by weight therein. Further, the pesticidal composition of the present invention can be an aerosol composition which comprises the above liquid composition and a propellant.
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the saturated hydrocarbons having 13 to 17 of carbon number may be branched saturated hydrocarbons, normal chained saturated hydrocarbons (tridecane, tetradecane, pentadecane, hexadecane and heptadecane), alicyclic saturated hydrocarbons and mixtures thereof.
Typical examples of said saturated hydrocarbon include petroleum solvent in the market such as Isopar M, Isopar V (mixtures of branched saturated hydrocarbons and alicyclic hydrocarbons produced by Exxon Chemical), Norpar 13, Norpar 15 (normal chained saturated hydrocarbons produced by Exxon Chemical), Neo-chiosol (normal chained saturated hydrocarbons produced by Chuo Kasei Co., Ltd.) and Exxol D110 (mixtures of normal chained and branched saturated hydrocarbons and alicyclic hydrocarbons produced by Exxon Chemical), and mixtures thereof.
The weight ratio of Compound A and the saturated hydrocarbon in the pesticidal composition of the present invention is usually from 1:15 to 1:9999, preferably 1:20 to 1:200.
The pesticidal composition of the present invention optionally comprises one or more of the other pesticidal active ingredients, synergists, perfumes and auxiliary solvents. Examples of the other pesticidal active ingredient include allethrin, tetramethrin, prallethrin, phenothrin, resmethrin, cyphenothrin, permethrin, cypermethrin, deltamethrin, cyfluthrin, furamethrin, imiprothrin, etofenprox, fenitrothion, propoxur, metoxadiazon, pyriproxyfen, methoprene, hydroprene, diflubenzuron, cyromazin, phenyl salicylate, benzyl benzoate, diethyl tetrephthalate and their pesticidally active optical/geometrical isomers if any. Examples of the synergist include piperonylbutoxide, N-(2-ethylhexyl)bicyclo[2.2.1]hept-5-ene-2,3-dicarboxyimide, octachlorodipropyl ether.
Examples of the auxiliary solvent include alkylbenzenes such as trimethylbenzene and dodecylbenzene; diarylethanes such as phenylxylylethane; ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone and isophorone; alcohols such as methanol, ethanol, isopropyl alcohol, hexanol and benzyl alcohol; mono- or diethers of ethylene glycol and propylene glycol; diethylene glycol monomethyl ether and monoethyl ether; 3-methoxy-3-methyl-1-butanol; 3-methoxy-3-methyl-1-butyl acetate; N-methyl-2-pyrrolidone; and propylene carbonate.
The aerosol composition of the present invention preferably utilized for total release type aerosol. Said aerosol composition usually comprises 20 to 50% by weight of the liquid composition of the present invention and 50 to 80% by weight of a propellant. Examples of the propellant include propane, n-butane, isobutane, dimethyl ether and mixtures thereof.
The liquid composition of the present invention, for example, can be prepared by mixing and dissolving Compound A and the saturated hydrocarbon having 13 to 17 of carbon number, and optionally the other pesticidal active ingredient mentioned above, synergist, perfume and auxiliary solvent, under room temperature or with heating.
Further, the aerosol composition of the present invention, for example, can be prepared by charging the liquid composition of the present invention in an aerosol container, fitting an aerosol valve to the container and charging a propellant through the stem.
In the case that the liquid composition of the present invention is used for pest-control, the liquid composition, which is usually a pesticidal oil solution, may be applied as it is.
In addition, the total release aerosol formulations of the present invention are more effective for controlling pests such as insects and acarina hiding in a space or shelter indoors. A total release aerosol is a known formulation that can release all the contents containing a pesticidal active ingredient in the aerosol container in a short time, and is usually used in a closed room. The total release aerosol comprises the liquid composition of the present invention and a propellant in an aerosol container crimped an aerosol valve and fitted total release type actuator on.
Example of the pests controlled by the present composition include acarina and insects. They are exemplified by house dust mites (for example, Dermatophagoides spp. such as
Dermatophagoides farinae, Dermatophagoides pteronyssinus
and so on; Acaridae such as
Lardoglyphus konoi, Tyrophagus putrescentiae, Aleuroglyphus ovatus
and so on; Glycyphagidae such as
Glycyphagus privatus, Glycyphagus domesticus, Glycyphagus destructor
and so on; Cheyletidae such as
Chelacaropsis moorei, Chelacaropsis malaccensis, Cheyletus fortis, Cheyletus eruditus, Chelatomorpha lepidopterorum
and so on; Macronyssidae such as
Ornithonyssus hacoti, Ornithonyssus sylviarum, Dermanyssus gallinae, Dermanyssus hirundinis
and so on; Haplochthonius spp.; Pyemotidae; itch mites; and so on); fleas such as cat flea, dog flea and so on; cockroaches such as German cockroach, smokeybrown cockroach, American cockroach and so on; Psocoptera such as
Liposcelis bostrychophilus, Liposcelis entomophilus
and so on; Formicidae such as
Monomorium pharaonis
and so on; Cimicidae such as
Cimex lectularius
and so on. Especially, the present composition is very effective for controlling house dust mites.
