Description

Stabilized pest control composition

[0001] The present invention relates to a pest control composition that has a high content of a pest control ingredient and / or has excellent self-emulsifying properties and emulsion stability when diluted with water.

[0002] Emulsifiable concentrates are commonly known as compositions having pesticidal effects. Conventionally, emulsions contain a solvent that dissolves a pesticidal component and a surfactant that emulsifies the solvent when diluted with water, and are used by diluting with water. Therefore, emulsions are required to have high solubility of the pesticidal component during low-temperature storage, self-emulsification ability when diluted with water, and / or excellent emulsion stability.

[0003] Patent Document 1 discloses an insecticidal composition containing a pesticide active ingredient, a solvent having a relative dielectric constant (εr) of 5 or more and a transition energy (ET(30)) of 38 kcal / mol or more, a nonpolar solvent, and a nonionic surfactant. Patent Document 1 lists N-methyl-2-pyrrolidone and N-butyl-2-pyrrolidone as examples of the solvent having a relative dielectric constant (εr) of 5 or more and a transition energy (ET(30)) of 38 kcal / mol or more.

[0020] [(2) Amide Solvents in Which an Alkyl Chain Having 1 to 4 Carbon Atoms is Binding to a Nitrogen Atom Constituting an Amide Bond] An amide solvent is a solvent in which an alkyl chain having 1 to 4 carbon atoms is bound to a nitrogen atom constituting an amide bond. The amide solvent is not particularly limited, but, for example, an amide solvent having a cyclic structure is preferred, and an amide solvent having a 5-membered ring structure is more preferred. Examples of the alkyl chain having 1 to 4 carbon atoms include a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, an isobutyl group, a sec-butyl group, and a tert-butyl group.

[0021] [(3) Nonionic Surfactants Having Aryl Ether (excluding Formalin Condensates)] The nonionic surfactant having an aryl ether is a nonionic surfactant having an aryl ether structure in its molecule. From the viewpoint of more effectively and reliably achieving the effects of the present invention, for example, an ether-type nonionic surfactant having an aryl ether is preferred. Examples of ether-type nonionic surfactants having an aryl ether include compounds having an aryl ether structure and a polyoxyalkylene structure in their molecules, such as compounds in which the aryl group is bonded to the polyoxyalkylene group via an oxygen atom. Examples of the aryl group include a phenyl group, a naphthyl group, and a benzyl group, and the aryl group may be modified with a substituent. In this specification, the terms polyoxyalkylene, polyoxyalkylene structure, and polyoxyalkylene group are used to describe similar structures, but the polyoxyalkylene is not particularly limited and includes polyoxyethylene, polyoxypropylene, polyoxyisopropylene, and polyoxytrimethylene. Polyoxyethylene and polyoxyisopropylene are preferred, and polyoxyethylene is more preferred. In nonionic surfactants having aryl ether, the aryl group in the aryl ether structure is not particularly limited, but may be modified with an allyl group, a styryl group, or may be styrenated. The aryl group in the aryl ether structure is not particularly limited, but examples thereof include polystyrylphenyl groups, tristyrylphenyl groups, distyrylphenyl groups, monostyrylphenyl groups (styrylphenyl groups), allylphenyl groups, distyrenated phenyl groups, and styrenated phenyl groups.

The nonionic surfactant having aryl ether may be a compound in which the aryl group and the polyoxyalkylene group are bonded via an oxygen atom, or may be a compound in any combination of the aryl group and the polyoxyalkylene group, but a compound in which the phenyl group and the polyoxyalkylene group are bonded via an oxygen atom is preferred.The nonionic surfactant having a phenyl ether is not particularly limited, and examples thereof include polyoxyalkylene polystyrylphenyl ether, polyoxyalkylene tristyrylphenyl ether, polyoxyalkylene distyrylphenyl ether, polyoxyalkylene distyrylphenyl ether, polyoxyalkylene styrylphenyl ether, polyoxyalkylene allylphenyl ether, polyoxyalkylene distyrylated phenyl ether, and polyoxyalkylene styrenated phenyl ether, with polyoxyethylene polystyrylphenyl ether, polyoxyethylene tristyrylphenyl ether, polyoxyethylene distyrylphenyl ether, polyoxyethylene styrylphenyl ether, polyoxyethylene allylphenyl ether, polyoxypropylene allylphenyl ether, polyoxyisopropylene allylphenyl ether, polyoxyethylene distyrenated phenyl ether, and polyoxyethylene styrenated phenyl ether being preferred. The nonionic surfactant having naphthyl ether is not particularly limited, but examples thereof include polyoxyalkylene naphthyl ether and polyoxyalkylene allyl naphthyl ether, with polyoxyethylene naphthyl ether being more preferred, and polyoxyethylene β-naphthyl ether being preferred.

In this embodiment, the nonionic surfactant having aryl ether may be used alone or in combination with other surfactants. Furthermore, it is preferable that the nonionic surfactant having aryl ether does not include formalin condensates. Here, formalin condensates refer to compounds obtained by condensing a nonionic surfactant having aryl ether with formalin. Furthermore, the nonionic surfactant having aryl ether may be used alone or in combination with two other surfactants.

[0022] The HLB of the aryl ether-containing nonionic surfactant (excluding formalin condensates) is not particularly limited, but from the viewpoint of more effectively and reliably achieving the effects of the present invention, it is usually 10 to 14.5, preferably 10 to 13, and more preferably 10 to 11. The HLB is a value that represents the degree of affinity of a surfactant for water and oil, and can be determined by the Griffin method.

[0023] The content of the aryl ether-containing nonionic surfactant is not particularly limited, but is typically 5 to 40% by mass, and preferably 10 to 25% by mass, relative to 100% by mass of the composition of this embodiment. By ensuring that the content of the aryl ether-containing nonionic surfactant is within the above range, it is possible to prevent the composition from separating when stored at or below room temperature, or from crystal precipitation when diluted with water and used, thereby preventing loss of homogeneity. Furthermore, it is possible to increase the content of components such as amide-based solvents contained in the composition of this embodiment, thereby suppressing crystal precipitation at or below room temperature. The content of the aryl ether-containing nonionic surfactant in the composition may be determined from the charge ratio during production of the composition, or may be determined by an external standard method, internal standard method, or the like using an analytical instrument such as HPLC.

The cylinder was then stopped and vigorously inverted 30 times per minute. The diluted solution was then allowed to stand in an incubator at 20°C for 2 hours, 5 hours, and 7 hours, after which the state of the diluted solution was visually observed and the emulsion stability was evaluated according to the following criteria. (Criteria) ◯: A uniform emulsion (diluted solution) was maintained. Δ: When the cylinder was slowly tilted, a creamy sediment accumulated at the bottom. This sediment was redispersed by shaking several times. ×: Crystal precipitation was observed.

[0079] The results of the composition stability, self-emulsifying ability of the diluted solution, and emulsion stability of the diluted solution for each surfactant type in the broflanilide formulation are shown in Table 1.

[0080] Table 1:

[0081] As shown in Table 1, the comparative compositions containing anionic surfactants exhibited crystal precipitation within 30 days of static storage under all temperature conditions. Furthermore, the compositions stored at -5°C and -15°C did not dissolve the precipitated crystals even after static storage at room temperature, demonstrating poor composition stability at room temperature or below. Furthermore, the compositions of Comparative Examples 2 to 11, which were nonionic surfactants but lacked phenol ether, exhibited poor self-emulsifying properties when gently poured onto the surface of water. Furthermore, the compositions of Comparative Examples 12 and 13, which were formalin condensates despite having a phenyl ether, exhibited poor emulsion stability, resulting in the deposition of crystals in the diluted solution. In contrast, the compositions of the Examples exhibited no crystal precipitation after long-term storage at room temperature or below, demonstrating excellent composition stability. Furthermore, when gently poured onto the surface of water, the compositions rapidly emulsified, demonstrating excellent self-emulsifying properties. Furthermore, the compositions of the Examples were gently poured onto the surface of water, capped, and vigorously inverted and mixed 30 times per minute. Even after being left to stand in an incubator at 20°C for more than two hours, the diluted solution maintained a uniform emulsion, demonstrating excellent emulsion stability.

[0092] As shown in Table 2, the compositions of Comparative Examples 14 to 17, which are amide-based solvents having an alkyl chain containing 8 or more carbon atoms, exhibited crystal precipitation within 30 days of static storage under any temperature condition. Alternatively, for compositions stored at -5°C and -15°C, the precipitated crystals did not dissolve even after static storage at room temperature, resulting in low composition stability at or below room temperature.
