ABSTRACT:
FIELD OF THE INVENTION
The instant invention relates to compositions which may be utilized to control pests.
BACKGROUND OF THE INVENTION
Various compounds and compositions have been utilized to control a pests but such compounds and compositions have failed to provide a effective control of pests.
U.S. Pat. No. 5,532,365 discloses 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine as a compound having a control over insects. U.S. Pat. No. 4,176,189 discloses [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate as an active ingredient of insecticides.
SUMMARY OF THE INVENTION
The instant invention provides compositions comprising 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine and [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate as active ingredients. Additionally, the instant invention provides methods of controlling pests comprising applying 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine and [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate to a pest or a locus where pests inhabit.
DETAILED DESCRIPTION OF THE INVENTION
1-Methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine and [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate which are present in the compositions typically act as active ingredients therein. The compositions typically comprise the active ingredients so that the total amount of 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine and [2,5-dioxo-3-(2-propynyl)- 1-imidazolidinyl]methyl chrysanthemate is from 0.005 to 50% by weight, wherein said percentage by weight is based on the total weight of the provided composition. In this regard, when the compositions are utilized to control pests, the compositions of the instant invention can have the total amount of the active ingredients therein at an amount which effectively controls pests. Further, the compositions typically comprise the active ingredients so that the weight-to-weight ratio of 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine to [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate is from 1:99 to 99:1, preferably 1:9 to 9:1, more preferably 3:1 to 1:3. Such weight-to-weight ratios in the compositions can vary, but when said compositions are utilized to control a pest, said compositions generally have a sufficient weight-to-weight ratio of 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine to [2,5-dioxo-3-(2-propynyl)- 1-imidazolidinyl]methyl chrysanthemate therein at a rate to provide a synergistic control over pests.
Since the compositions can contain various active isomers of [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate, any active stereoisomer of [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate or mixture thereof can be utilized in the instant invention, if so desired. Examples of stereoisomes of [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate which can be utilized in the instant invention include [2,5-dioxo-3-(2-propynyl-1-imidazolidinyl]methyl (1RS)-cis,trans-chrysanthemate, [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl (1R)-cis,trans-chrysanthemate (common name imiprothrin), [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl (1R)-trans-chrysanthemate and the like.
The compositions of the instant invention are typically formulated as suitable formulations of 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine and [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate. Examples of such formulations of the inventive compositions include liquid formulations, dusts, wettable powders, granules, paste formulations, microencapsulated formulations, foaming formulations, aerosols, liquid carbon dioxide solution formulations, tablets, poison baits, smoking formulations, fogging formulations, sheet formulations, resin formulations and the like. Examples of said liquid formulations of the compositions include emulsifiable concentrates, oil formulations, spot-on formulations, pour-on formulations, shampoo formulations, suspensible concentrates and the like.
Such formulations of the compositions can be produced by well known formulating procedures. For example, a formulation of the instant invention can be produced by mixing together 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine and [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate and optionally adding thereto or mixing therewith formulation auxiliaries or carriers. Based on the formulation type of the compositions, said formulations may also be produced by forming said mixture into a suitable form, if so desired. As such, the formulations of the compositions may contain 1-methyl-2-nitro-3-[(3-tetrahydrofuryl)methyl]guanidine and [2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl]methyl chrysanthemate without additional components, but may additionally contain the carrier or formulation auxiliary, if so desired.
Examples of formulation auxiliaries which can be utilized in the compositions include emulsifiers, dispersing agents such as a lignin sulfonate salt and methylcellulose, adhesive agents such as carboxymethylcellulose, gum arabic, polyvinyl alcohol and polyvinyl acetate, coloring agents such as iron oxide, titanium oxide, Persian blue, alizarine dye, azo dye and phthalocyanine dye and the like. Examples of said emulsifiers which can be utilized in the instant invention include ionic emulsifiers such as an alkylsulfonate salt, alkylsulfate salt, alkylarylsulfonate salt and arylsulfonate salt, nonionic emulsifiers such as a polyoxyethylene fatty acid ester, polyoxyethylenealkylaryl ether and polyoxyethylene fatty acid alcohol ether and the like.
The compositions of the instant invention generally utilize therein a carrier selected form a solid carrier, a liquid carrier and a propellant, when present. In such cases in which the compositions additionally contain a carrier, said compositions typically contain the carrier in an amount of from 50% to 99.995%, wherein said percentage by weight is based on the total weight of the provided composition.
Examples of solid carriers which can be utilized in the compositions include gelatin, vaseline, methyl cellulose, lanolin, lard, natural-occurring or synthetic minerals such as clay, kaolin, talc, bentonite, sericite, quartz, sulfur, activated carbon, calcium carbonate, diatomaceous earth, pumice stone, calcite, meerschaum, dolomite, silica, alumina, vermiculite and perlite, fine granules such as granulated sawdust, corncob, coconut shell and tobacco stems and the like.
Examples of liquid carriers which can be utilized in the compositions include liquid paraffins, aromatic or aliphatic hydrocarbons such as xylene, toluene, alkylnaphthalene, phenylxylylethane, kerosene, gas oils, hexane and cyclohexane, halogenated hydocarbons such as chlorobenzene, dicloromethane, dichloroethane and trichloroethane, alcohols such as methanol, ethanol, isopropyl alcohol, butanol, hexanol and ethylene glycol, ethers such as diethyl ether, ethylene glycol dimethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, tetrahydrofuran and dioxane, esters such as ethyl acetate and butyl acetate, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone and cyclohexanone, nitriles such as acetonitrile and isobutyronitrile, amides such as N,N-dimethylformamide and N,N-dimethylacetamide, botanical oils such as soybean oil and cotton seed oil, botanical essential oils such as orange oil, hyssop oil and lemon oil, water and the like.
Examples of propellants which can be utilized in the compositions include propane gas, butane gas, flon gas, liquified petroleum gas (LPG), dimethyl ether, carbonate gas and the like. By utilizing the propellant in the compositions, the compositions may be formulated into the foaming formulations
