Description

[Technical Field]

[0001] This invention relates to liquid pesticide compositions. [Previous Technology]

[0002] In pesticide formulations, compared to non-aqueous liquid formulations, aqueous formulations impose less burden on the environment and are safer for users, as they are non-flammable. Generally, a known method for manufacturing aqueous liquid formulations is to micronize the pesticide components to create a suspension. However, pesticide components with a certain degree of water solubility are difficult to suspend as a formulation. In such cases, a liquid component with high pesticide solubility must be added to the water to dissolve the active ingredient in the liquid component to create a liquid formulation. For example, Patent Document 1 discloses a liquid formulation containing a mixture of pesticide components, a solvent, and water, wherein the pesticide component has a higher solubility in the mixed solvent than in the solvent or water.

[0008] The liquid pesticide composition of the present invention exhibits excellent storage stability, with the crystallization and precipitation of the active pesticide component suppressed during storage. Furthermore, even when used after dilution with water, the precipitation of crystals in the diluted solution is suppressed. Moreover, the present invention provides a liquid pesticide composition with low ignition risk and excellent safety.

Implementation Method

[0009] Hereinafter, the liquid pesticide composition of the present invention will be described according to embodiments. In addition, unless otherwise specified, "~" means from "above" to "below". The liquid pesticide composition of the present embodiment includes: a) an active ingredient having a water solubility of 1 g / L to 100 g / L at 25°C; b) a solvent represented by the following general formula (1); c) a glycol ether solvent; and d) water.

[0010] The active ingredient used in the liquid pesticide composition of this embodiment, having a water solubility of 1 g / L to 100 g / L at 25°C, can be of any type, as long as it is effective against pests. Examples include neonicotinoid insecticides, with acetamiprid (4.25 g / L), datnam (39.8 g / L), nitenpyram (590 g / L), and thiamethoxam (4.1 g / L) being preferred, and datnam being especially preferred. The blending ratio of the active ingredient is not particularly limited, but if the concentration of the active ingredient is low, the water dilution ratio will be lower during actual treatment, increasing transportation and storage costs. Therefore, relative to 100% by weight of the liquid pesticide composition, it is typically 4–40% by weight, more preferably 5–30% by weight, with 7–20% by weight being ideal.

[0011] The liquid pesticide composition of the present invention exhibits excellent low-temperature storage stability, particularly when it contains a high concentration of the active pesticide ingredient. That is, even when the active ingredient (a) is incorporated within the above-mentioned range, the crystallization and precipitation of the active ingredient (a) can be suppressed at low temperatures, demonstrating excellent storage stability. Low temperature refers to the winter air temperature at which the liquid pesticide composition may be exposed, specifically -20°C to 5°C.

[0012] The liquid pesticide composition of this embodiment includes b) the solvent shown in the following general formula (1).

[0013]

[0014] In general formula (1), A is selected from -CH2-, -C2H4-, -CH(CH3)-, -OC2H4-, -CH2OC2H4-, -OCH2CH(CH3)-, -OCH(CH3)CH2-, -OC2H4-OC2H4-. In this embodiment, A is preferably selected from -CH2-, -C2H4-, -OC2H4-, -OCH2CH(CH3)-, -OCH(CH3)CH2-. b) The solvent may include one or more solvents selected from those shown in general formula (1).

[0015] From the viewpoint of the effectiveness of the present invention, relative to 100% by weight of the liquid pesticide composition, b) the solvent is typically 5-50% by weight, more preferably 8-40% by weight, with 10-35% by weight being more ideal. From the viewpoint of the effectiveness of the present invention, the ratio (b / a) of the solvent content (parts by weight) to the active ingredient content (parts by weight) is typically 0.2-10, more preferably 0.5-8, with 1-5 being more ideal.

[0016] The liquid pesticide composition of this embodiment includes c) a glycol ether solvent. Examples of c) glycol ether solvents include: ethylene glycol monomethyl ether, diethylene glycol monomethyl ether, triethylene glycol monomethyl ether, polyethylene glycol monomethyl ether, ethylene glycol monoisopropyl ether, dipropylene glycol, diethylene glycol monoisopropyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, triethylene glycol monobutyl ether, ethylene glycol monoisobutyl ether, diethylene glycol monoisobutyl ether, ethylene glycol monoallyl ether, diethylene glycol monobenzyl ether, propylene glycol monomethyl ether, dipropylene glycol monomethyl ether, tripropylene glycol monomethyl ether, propylene glycol monopropyl ether, diethylene glycol dimethyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, diethylene glycol methyl ethyl ether, diethylene glycol diethyl ether, diethylene glycol, ethylene glycol, and propylene glycol.

[0017] Preferably, the solvents are diethylene glycol monomethyl ether, dipropylene glycol, diethylene glycol monoisopropyl ether, triethylene glycol dimethyl ether, ethylene glycol, propylene glycol, triethylene glycol monomethyl ether, diethylene glycol, triethylene glycol monobutyl ether, dipropylene glycol monomethyl ether, diethylene glycol dimethyl ether, polyethylene glycol monomethyl ether, propylene glycol monomethyl ether, ethylene glycol monoisopropyl ether, ethylene glycol monoallyl ether, and ethylene glycol monomethyl ether. c) Diethylene glycol ethers are solvents, and one or more selected from these solvents may be used.

[0018] From the viewpoint of the effectiveness of the present invention, relative to 100% by weight of the liquid pesticide composition, c) the glycol ether solvent is typically 1-50% by weight, more preferably 2-40% by weight, with 3-35% by weight being more ideal. From the viewpoint of the effectiveness of the present invention, the ratio (c / a) of the content (parts by weight) of c) the glycol ether solvent to the content (parts by weight) of a) the active ingredient is typically 0.1-10, more preferably 0.2-5, with 0.3-3 being more ideal.

[0019] The liquid pesticide composition of this embodiment contains b) a solvent of general formula (1) and c) a glycol ether solvent as solvents, thereby suppressing the crystallization of a) the active ingredient in the liquid pesticide composition, and exhibiting excellent storage stability at low temperatures, especially when the active ingredient is present at a high concentration. Furthermore, even when the liquid pesticide composition is diluted with water for use, the precipitation of crystals in the diluted solution can be suppressed.

[0020] From this perspective, the ratio (by weight) of the total amount (parts by weight) of the solvent (b) and the glycol ether solvent (c) to the content (parts by weight) of the active ingredient (a) ((b+c) / a) is usually 0.5 to 15, more preferably 1 to 10, with 2 to 8 being more ideal. Furthermore, the mixing ratio (c / b) of the glycol ether solvent (c) to the solvent (b) is usually 0.05 to 5, more preferably 0.08 to 2, with 0.1 to 1.5 being more ideal.

[0021] The water used in the liquid pesticide composition of this embodiment (d) can be any type of water, such as groundwater, tap water, ion-exchanged water, or distilled water. Furthermore, the mixing ratio of water is not particularly limited, but if the mixing ratio is too low, crystallization of the active ingredient with a solubility of 1 g / L to 100 g / L in water at 25°C may occur during storage. This may also cause flammability issues. Conversely, if the mixing ratio is too high, the proportion of other solvents and other components in the liquid pesticide composition will decrease, and crystallization may occur during storage. Therefore, the mixing ratio of water relative to 100% by weight of the liquid pesticide composition is typically 1–50% by weight, more preferably 2–30% by weight, with 4–25% by weight being ideal.

[0022] From the viewpoint of the effectiveness of the present invention, the ratio (d / a) of the water content (parts by weight) to the content (parts by weight) of the active ingredient (a) is generally 0.2 to 10, more preferably 0.5 to 5, and 0.8 to 3 is more ideal. The ratio (b+c) / d) of the total amount (parts by weight) of the solvent and the glycol ether solvent to the water content (parts by weight) is generally 0.5 to 8, more preferably 1 to 5, and 1.5 to 3 is more ideal.

[0023] The liquid pesticide composition of this embodiment may further include e) a surfactant. By including e) a surfactant, the crystallization and precipitation of the active ingredient and the separation within the liquid pesticide composition can be further suppressed, especially the low-temperature storage stability when the active ingredient is present at a high concentration. As e) a surfactant, one or more selected from nonionic surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants commonly used in pesticides can be used in combination. Preferably, nonionic surfactants and anionic surfactants are used in combination.

[0036] The blending ratio of surfactant e) in the liquid pesticide composition of this embodiment is not particularly limited. However, if the blending ratio is too low, the formulation may separate during storage or the oil components may separate during dilution and use, thus compromising homogeneity. Furthermore, if the blending ratio is too high, the proportion of other solvents and other components in the liquid pesticide composition will decrease, which may lead to crystallization during storage. Therefore, the total blending ratio of each surfactant relative to 100% by weight of the liquid pesticide composition is typically 5-50% by weight, and more preferably 10-30% by weight.

[0037] The liquid pesticide composition of this embodiment may further include an active ingredient with a water solubility of less than 100 mg / L at 25°C.

The blending ratio of this active ingredient is not specifically limited, but relative to 100% by weight of the liquid pesticide composition, it is usually 1–40% by weight, more preferably 5–30% by weight, with 7–20% by weight being ideal.
