Description

The present invention relates to a granular pesticide composition containing a pesticide active ingredient and a method for producing the same, and more particularly to a granular pesticide composition having an excellent immediate release of the pesticide active ingredient and a method for producing the same. ..

In recent years, rapid dissolution of pesticide active ingredients has been required for the purpose of rapidly and maximizing the effects of pesticide active ingredients. In general, pesticide active ingredients used for paddy rice are often used in the form of granules from the viewpoint of labor saving and safety at the time of application. The term "granule" as a term in the art refers to a granular pesticide composition that is planned to be applied in a granular form at the time of use.

As a general aspect of the granular pesticide composition used as a granule, the pesticide active ingredient and a solid carrier such as clay or calcium carbonate are mixed, water is added to the mixture obtained as described above, and the mixture is kneaded and determined. Examples thereof include those produced by extruding and granulating using a die having a pore size and then drying.

Further, as another embodiment, lignin sulfonate, polyvinyl alcohol, carboxymethyl cellulose, methyl cellulose, starch, dextrin, and polyacrylic acid are formed on the surface layer of a grain nucleus having an appropriate particle size obtained by crushing or granulating a mineral substance or the like. Granules coated with a pesticide active ingredient using a binder such as acid salt are also known (Patent Document 1).

JP 2013-35761

However, especially in the former aspect of the granular pesticide composition, since the pesticide active ingredient is contained in the granules, the elution of the pesticide active ingredient becomes slow, and when immediate release is expected, the result is unsatisfactory. It happened to be. Further, in the latter aspect of the granular pesticide composition, it cannot be said that the immediate release property is sufficient depending on the pesticide active ingredient, and there may be room for further study.

Therefore, an object of the present invention is to provide a granular pesticide composition having excellent immediate release of a pesticide active ingredient.

As a result of diligent studies to develop a quick-release granular pesticide composition, the present inventors have used a saccharide that does not crystallize at room temperature in place of a conventional binder to support the pesticide active ingredient on the surface of the grain nucleus. As a result, we have found that it exhibits excellent quick-release properties, and have completed the present invention.

According to the present invention, it is possible to provide a granular pesticide composition having excellent immediate release of a pesticide active ingredient and a method for producing the same.

The granular pesticide composition of the present invention is a powder having a grain nucleus and an outer layer portion covering the grain nucleus, the outer layer portion containing liquid sugar which is a saccharide that does not crystallize at room temperature, and containing a pesticide active ingredient. The body is supported on the outer layer portion. Since the granular pesticide composition of the present invention is excellent in quick-release of the pesticide active ingredient, it is expected to exert a strong medicinal effect.

The shape of the grain core of the granular pesticide composition of the present invention is not particularly limited, but a granular material having an appropriate particle size as a pesticide granule is preferable, and more specifically, a substantially spherical material having a diameter of 0.1 to 30 mm or a substantially spherical material. An amorphous object having a volume sphere equivalent diameter of 0.1 to 30 mm, a substantially cylindrical object having a diameter of 0.1 to 5 mm, a length of 0.1 to 30 mm, and an aspect ratio (length / diameter) of 1 to 10 is preferable. Can be used. Among them, substantially cylindrical objects having a diameter of 0.3 to 1.7 mm, a length of 0.3 to 10.2 mm, and an aspect ratio of 1 to 6 are preferable, and a diameter of 0.5 to 1.5 mm and a length of 0.5 to 7 are preferable. A substantially cylindrical object having a diameter of 0.5 mm and an aspect ratio of 1 to 5 is more preferable, and a substantially columnar object having a diameter of 0.8 to 1.2 mm, a length of 0.8 to 4.8 mm, and an aspect ratio of 1 to 4 is even more preferable.

Further, the material of the grain core is not particularly limited, and for example, an amorphous product obtained by crushing a mineral or the like can be used, but a fine powder solid carrier and, if necessary, a surfactant and a bond are used. Other components such as agents, lubricants, colorants and, if desired, chemical damage mitigating agents, are usually mixed and granulated with an extrusion granulator, agitated granulator, rolling granulator or fluidized bed granulator. Granulated products manufactured using a machine can also be used. Of these, granulated products obtained by the extrusion granulation method are preferable.

Examples of the fine powdery solid carrier that can be blended in the granulated product include bentonite, clay, kaolin, cericite, talc, acid clay, pumice, zeolite, vermiculite, perlite, calcium carbonate, silica sand and the like. These may be used alone or in combination of two or more.

These may be used alone or in combination of two or more.

When the granulated product is used as a granule, the pesticide active ingredient may be contained in the granule, if desired. Further, if desired, an elution control agent such as waxes, resins, or hydrophobic substances may be contained in the granules for the purpose of adjusting the elution rate of the pesticide active ingredient blended in the granules.

In the granular pesticide composition of the present invention, it is important that the outer layer portion covering the grain nuclei contains liquid sugar, which is a saccharide that does not crystallize at room temperature. Here, liquid sugar is generally called molasses. The types of liquid sugar include sweet potato sugar syrup, citrus sugar syrup, refined sugar final sugar syrup, and ice sugar syrup produced in the sugar manufacturing process, and conversion sugar containing reduced sugar, for example, sucrose hydrolyzed into glucose and fructose. Examples thereof include those containing converted sugar together with non-reducing sugar such as sugar and sucrose, and converted sugar containing reduced sugar, that is, converted liquid sugar containing reduced sugar is preferable. Among the converted liquid sugars, those containing 20% or more of reduced sugar content are preferable, those containing 40% or more of reduced sugar content, and conversion type liquid sugar containing about 50%, that is, 45 to 54% of reduced sugar content. Is particularly preferable.

The content of the liquid sugar is not particularly limited, and may depend on the amount of the powder containing the pesticide active ingredient to be supported on the outer layer of the grain nucleus, but is preferably 0.5 with respect to the entire granular pesticide composition. It is ~ 5% by mass, more preferably 0.8 ~ 2% by mass. If the content of the liquid sugar is insufficient, the function of supporting the powder containing the pesticide active ingredient in the outer layer of the grain nucleus may be insufficient, while if the content of the liquid sugar is excessive, the granular pesticide may be insufficient. There is concern about consolidation of the composition.

In the granular pesticide composition of the present invention, it is also important to support the powder containing the pesticide active ingredient on the outer layer portion of the grain nucleus. This powder can contain one or more pesticide active ingredients, and if desired, pulverizing aids such as silica, diatomaceous earth, and silica sand, lignin sulfonates, aryl sulfonates, and alkyl sulfates. Surfactants such as, bentonite, clay, solid carriers such as calcium carbonate, and auxiliary agents such as alkali metal salts, alkaline earth metal salts, and stabilizers such as epoxidized oils and fats may be blended.

The pesticide active ingredient contained in such powder may be used as it is, but in order to support it on the outer layer portion of the grain nucleus, it is usually finely pulverized to a particle size of 50 μm or less, preferably 10 μm or less and used as a powder. Is desirable. As the means for such fine crushing, a known crushing device can be arbitrarily used, and specifically, an impact type crusher, an airflow type crusher, or the like can be used, but is not particularly limited. Further, at the time of the fine pulverization, the pesticide active ingredient may be pulverized alone, or if desired, it may be mixed with the auxiliary agent or the like in advance and co-pulverized.

The content of the pesticide active ingredient supported on the outer layer of the grain nucleus is not particularly limited, but is preferably 0.1 to 3% by mass, more preferably 0.2 to 2% by mass, based on the entire granular pesticide composition. is there.

The method of coating the granules with an outer layer containing liquid sugar and supporting the powder containing the pesticide active ingredient on the outer layer is not particularly limited, but typically, the granules are first subjected to a concrete mixer, a nauta mixer, or the like. While mixing using a normal mixer, a binder solution containing liquid sugar is added to cover the surface layer of the grain nucleus to form an outer layer, and then a powder containing a pesticide active ingredient is added. Therefore, a method of supporting the outer layer portion can be exemplified. In such a method, the powder containing the pesticide active ingredient can be supported on the outer layer portion of the grain nucleus by the adhesive force of the liquid sugar.

Since the liquid sugar used in the granular pesticide composition of the present invention is usually a honey-like viscous liquid at room temperature, it is difficult to coat the surface layer of the grain nucleus with the binder liquid containing this liquid sugar. There is. Examples of the means for solving this problem include a method of heating the binder solution to reduce the viscosity of the binder solution, and a method of adding a small amount of a solvent such as water to the liquid sugar to reduce the viscosity of the binder solution. be able to. When water is added to the liquid sugar to prepare a binder liquid, the amount of water added is not particularly limited, but it is appropriate to add water up to about 30% by mass with respect to the total amount of the binder liquid. When the composition of the binder liquid is excessive, that is, dilute, it is necessary to add a large amount of the binder liquid in order to cover the granules with an effective amount of liquid sugar, and the granules wet by the excess water aggregate with each other. This may interfere with the subsequent step, that is, the step of coating and supporting the powder containing the pesticide active ingredient.

In the granular pesticide composition of the present invention, the pesticide active ingredient carried on the outer layer of the grain nuclei and, if desired, the pesticide active ingredient contained in the granule nuclei are not particularly limited. Further, the outer layer portion of the grain nucleus and the grain nucleus can each contain one or more kinds of pesticide active ingredients, and they may be the same or different. However, as the pesticide active ingredient supported on the outer layer of the grain nucleus, it is highly probable that the pesticide active ingredient elutes quickly, so it is preferable to use the pesticide active ingredient expected to have a quick effect. .. Examples of such pesticide active ingredients include herbicidal active ingredients, insecticidal active ingredients, bactericidal active ingredients and plant growth regulator active ingredients listed below, and among them, the pesticide active ingredients used in the examples are preferably used. Be done. On the other hand, when it is desired to contain a pesticide active ingredient that is expected to have a slow-acting or long-lasting medicinal effect, it is rational to consider the formulation in the grain nucleus.
