Description

This invention relates to a liquid pesticide composition. U.S. Patent No. 6,537,948 (Patent Document 1) describes a compound represented by formula (I) as an active ingredient in herbicides. It is stated. U.S. Patent No. 6,537,948 The liquid pesticide composition according to the present invention (hereinafter also simply referred to as "liquid pesticide composition") is (a) Compound represented by formula (I) (Hereafter also referred to as "Compound (I)") (b) A solvent having a water solubility of 10% by mass or less at 25°C. (c) A surfactant, and (d) Water in an amount of 0.04% by mass or more and 3.30% by mass or less. In this specification, "liquid" means fluid at 25°C. A liquid pesticide composition is preferably a liquid in which at least the active pesticide component is completely or nearly completely dissolved in the solvent. More preferably, a liquid pesticide composition is a liquid in which at least the active pesticide component, surfactant, and water are completely or nearly completely dissolved in the solvent. Even more preferably, a liquid pesticide composition is a liquid in which all of its components are completely or nearly completely dissolved in the solvent. According to the present invention, a liquid pesticide composition with good storage stability at low temperatures can be provided. Examples of low-temperature storage conditions include storage in an environment below 0°C, storage in an environment below -10°C, and storage in an environment below -20°C. Examples of low-temperature storage periods include storage for one day or more, storage for one week or more, storage for one month or more, storage for one year or more, and storage for two years or more. The components contained in or potentially contained in the liquid pesticide composition according to the present invention will be described in detail below. (a) Compound (I) The liquid pesticide composition contains compound (I) as the pesticide active ingredient. Compound (I) is a known compound and is represented by the following formula (I). Compound (I) can be produced by known methods, such as the method described in U.S. Patent No. 6,537,948. When the total amount of the liquid pesticide composition is 100% by mass, the content of compound (I) in the liquid pesticide composition is generally 0.1% by mass or more and 50% by mass or less, preferably 0.5% by mass or more and 40% by mass or less, more preferably 1% by mass or more and 30% by mass or less, even more preferably 2% by mass or more and 25% by mass or less, and still more preferably 3% by mass or more and 20% by mass or less. Other preferred ranges for this content are, for example, 3% by mass or more and 12% by mass or less, 3% by mass or more and 10% by mass or less, 4% by mass or more and 15% by mass or less, 4% by mass or more and 12% by mass or less, or 5% by mass or more and 10% by mass or less. (b) Solvent The liquid pesticide composition contains one or more solvents (hereinafter also referred to as "hydrophobic solvents") whose water solubility at 25°C is 10% by mass or less. Examples of hydrophobic solvents include, Alcohols such as butanol, amyl alcohol, hexanol, heptanol, octanol, 2-ethylhexanol, cyclohexanol, and benzyl alcohol; Esters such as acetate esters (e.g., ethyl acetate, butyl acetate, isoamyl acetate, isobornyl acetate, hexyl acetate, heptyl acetate, octyl acetate, benzyl acetate), carbonate esters (e.g., diethyl carbonate, dibutyl carbonate), fatty acid esters (e.g., isopropyl myristate, methyl octanoate, methyl oleate, methyl laurate, dimethyl adipate, dibutyl adipate, didecyl adipate, tri-n-butyl citrate, di-n-butyl phthalate, methyl caprylate, methyl laurate, methyl myristate, methyl salicylate, methyl palmitate, methyl oleate, ethyl palmitate), phthalate esters (e.g., dimethyl phthalate, diethyl phthalate), benzoate esters (e.g., methyl benzoate, ethyl benzoate), succinate esters (e.g., dioctyl succinate), acetoacetate esters (e.g., tert-butyl acetoacetate, allyl acetoacetate); ethers such as propylene glycol phenyl ether; Ketones such as cyclohexanone, 2-heptanone, isophorone, mesityl oxide, methylisoamyl ketone, methylisobutyl ketone, methylcyclohexanone, and acetophenone; Amides such as fatty acid dimethylamides (e.g., N,N-dimethyldecanamide, N,N-dimethyldodecanamide, N,N-dimethyltetradecanamide, N,N-dimethyloctadecanamide), alkylpyrrolidones (e.g., N-octylpyrrolidone, N-dodecylpyrrolidone, N-decylpyrrolidone); Lactones such as γ-octanolactone and δ-octanolactone; Amines such as n-octylamine, oleylamine, and laurylamine; Aliphatic hydrocarbons such as decane, tridecane, tetradecane, hexadecane, octadecane, normal paraffins, isoparaffins, cycloparaffins, 1-undecene, and 1-heneicosene; Aromatic hydrocarbons such as toluene, xylene, alkylbenzenes including ethylbenzene, octadecylbenzene, dialkylbenzene and trialkylbenzene, alkylnaphthalenes including methylnaphthalene, dimethylnaphthalene, dodecylnaphthalene and tridecylnaphthalene,
