[Solution] A granular agricultural composition containing an active pesticide component and a polyhydric alcohol, which has the property of disintegrating in water.

Description

Technical Field

[0001] The present invention relates to an agricultural granular composition that is excellent in disintegration and dispersibility in water and ensures the temporal stability of these physicochemical properties.

Background Art

[0002] Conventionally, pesticide formulations used in paddy fields and the like are generally granules, powders, emulsions, wettable powders, and flowable agents. Among these pesticide formulations, granules have a granular appearance with a short diameter of approximately 0.3 to 1.7 mm and are used as they are for treatment in seedling boxes, agricultural fields, and the like. Among the important physicochemical properties of granules, there are disintegration and dispersibility. For example, when it is required to uniformly coat the active ingredient on the soil surface, the granules need to disintegrate rapidly in water so that the active ingredient is uniformly dispersed. On the contrary, when it is required to reduce phytotoxicity or improve residual efficacy, there are cases where rapid disintegration is not required and sustained release of the active ingredient is required.

[0003] Various techniques for producing granules excellent in disintegration and dispersibility in water have been proposed so far. For example, Patent Document 1 reports a pesticidal granule containing a polymer obtained by graft polymerization of vinylpyrrolidone onto polyvinyl alcohol, which has a disintegrating property of rapidly disintegrating and diffusing when put into water. On the other hand, if the disintegration of the granules is too fast, the concentration of the active ingredient may become locally high, and phytotoxicity may become a problem, so it is an issue to appropriately adjust the disintegration time. For example, Patent Document 2 reports a paddy field herbicidal granule with an adjusted disintegration time, which contains a natural product or its derivative that gelatinizes by heating, by mixing with water, or by mixing with water and heating, and an enzyme that acts on the natural product or its derivative, and contains cyhalofop-butyl and simetryn as active ingredients.

[0004] However, even if these technologies exhibit good disintegration and dispersibility immediately after manufacturing, they may deteriorate over time due to the influence of the active ingredients and auxiliary materials contained, and may not maintain good disintegration and dispersibility. For example, Patent Document 3 describes that when a high concentration of a water-insoluble herbicide component is included, the dispersion in water after the granules disintegrate becomes insufficient, and furthermore, when a water-soluble, low-melting-point herbicide component is included, the disintegration of the granules deteriorates over time, resulting in insufficient dispersion of the water-insoluble herbicide component in water.

[0005] Incidentally, regarding agricultural granular compositions containing pesticide active ingredients and polyethylene glycol, for example, Patent Document 4 describes a granular wettable pesticide characterized by containing ethylene glycol, propylene glycol, or polyethylene glycol or polypropylene glycol with a molecular weight of 1000 or less in an agricultural granular composition containing one or more pesticide active ingredients. The aforementioned granular wettable pesticide reduces powdering without reducing disintegration properties by incorporating polyethylene glycol. Since granular wettable pesticides are diluted with water before application, they are required to disintegrate and disperse quickly when stirred in water. However, the concept of stirring does not apply to granules that are applied in their original form without dilution with water, and the disintegration property of granules refers to the property of disintegrating and dispersing on their own without stirring. Furthermore, in the case of granules, the disintegration property exhibited by granular hydrates is too rapid, raising concerns about causing phytotoxicity.

[0006] As described above, there had been no prior evidence that polyhydric alcohols such as polyethylene glycol contribute to the disintegration, dispersibility, and long-term stability of their physicochemical properties in granular materials. [Prior art documents] [Patent Documents]

[0029] The composition of the present invention can be produced by kneading, granulating, and sizing the above components according to conventional methods, followed by drying. As a first method of production, for example, an active pesticide component, a polyhydric alcohol, and other components (surfactants, binders, floating carriers, solid carriers, etc.) are mixed, and an appropriate amount of water is added and kneaded. Using a known granulator, the resulting mixture is granulated, sizing to a desired particle size, and then dried to obtain the composition of the present invention. As a second manufacturing method, for example, an active pesticide component and other components (surfactants, binders, floating carriers, solid carriers, etc.) are mixed, and an appropriate amount of water is added and kneaded. Using a known granulator, the resulting mixture is granulated, the granules are impregnated with polyhydric alcohol, the granules are sized to the desired particle size, and then dried to obtain the composition of the present invention. Of these, the first manufacturing method is preferred from the viewpoint of disintegration and dispersibility. In the second manufacturing method, in which granules containing the active pesticide component and other components are prepared and then impregnated with polyhydric alcohol, the distribution of polyhydric alcohol in the composition of the present invention is not uniform, resulting in reduced disintegration and dispersibility, which is undesirable.

[0030] Mixing can be carried out using known mixers such as ribbon type, V type, conical screw type, and high-speed fluid type. Granulation can be carried out using known granulators such as rolling granulators, extrusion granulators, compression granulators, and agitation granulators. Next, the granulated material can be sized using a known sizing machine such as a rolling sizing machine, and then dried using a known dryer such as a fluidized bed dryer, vibrating fluidized bed dryer, or airflow dryer.

[0031] The composition of the present invention has the property of disintegrating in water, preferably within 30 minutes, more preferably within 20 minutes, and even more preferably within 6 to 15 minutes. Whether or not it has this property of disintegrating in water can be confirmed by measuring the time it takes for the composition of the present invention to disintegrate after being added to water. To obtain a composition of the present invention having such properties, the disintegration time can be adjusted as appropriate by adjusting the blending ratio of the surfactant, etc. It is also possible to apply known manufacturing techniques that are known to increase or decrease the disintegration time.

[0032] The short diameter of the composition of the present invention is not particularly limited, but is usually 0.3 to 1.7 mm, preferably 0.8 to 1.2 mm. A short diameter of 0.8 to 1.2 mm is preferable because it has excellent dispersibility and disintegration properties, making it particularly suitable for application in paddy fields where these properties are especially important. To obtain the composition of the present invention with the above short diameter, granulation and sizing can be performed as appropriate. In particular, the short diameter can be easily adjusted by performing extrusion granulation using a screen with holes of a predetermined diameter.

[0033] The composition of the present invention obtained as described above has excellent disintegration properties and uniform dispersibility due to the presence of polyhydric alcohols. Therefore, when the composition of the present invention is sprayed on paddy fields, etc., uneven distribution of the contained pesticide active ingredients is less likely to occur, and the occurrence of phytotoxicity can be suppressed. Furthermore, since the disintegration properties and dispersibility of the composition of the present invention are stable over time, it can be stored for a long period of time.

[0034] Depending on the type of active pesticide component contained in the composition of the present invention, the purpose of application, application location, application timing, application method, application rate, etc., can be appropriately selected.

[0035] The purposes of application include, for example, disease control, pest control (insecticidal active ingredients, acaricidal active ingredients, nematicidal active ingredients, etc.), weed control, and plant growth regulation; the application sites include, for example, agricultural land such as fields, rice paddies, lawns, and orchards, as well as non-agricultural land; the application timing includes, for example, before or after sowing, before or after transplanting; the application methods include, for example, direct application by hand, manual sprayers, backpack-type power sprayers, mobile power sprayers, tractor-mounted sprayers, rice transplanter-mounted sprayers, side-dressing sprayers, and aerial sprayers such as drones; the application rate is, for example, 250 to 3000 g per 10 ares of agricultural land.
