Description
【発明の詳細な説明】 この発明は、表面が固着剤で粉衣された農園芸用顆粒
水和剤およびその製造法に関するものである。The present invention relates to a wettable powder for agricultural and horticultural use, the surface of which is coated with a fixing agent, and a method for producing the same.
農園芸の分野では、最近、顆粒水和剤が有利な新剤型

に残らない等の利点を有する。In the field of agriculture and horticulture, granule wettable powder has recently been noted as an advantageous new dosage form. Granule wettable powder is (1) less dusty than conventional fine powder wettable powder, and less inhalation of drug and skin contact at the manufacturing site or preparation of spray liquid, (2) drug It has the advantages that it is easy to weigh and that no drug remains in the packaging container.

成した。Granule wettable powder is a pesticide active ingredient drug substance, dispersant, binder,
It comprises a wetting agent, a carrier and the like, and is manufactured through steps such as hydration, kneading, granulation and drying. When the water dispersible granules are put into water at the time of use, they rapidly disintegrate and disperse to prepare a spray liquid having good suspendability. Having a good disintegrating dispersibility when preparing a drug solution is an important factor, but this also shows that when the drug solution is sprayed on plants, it is easily dried and then washed away by rainfall, which is also a disadvantage. . It is possible to add a sticking agent to impart rain resistance, but in the production of a wettable granule, adding a sticking agent to add water, kneading, granulating, and drying gives a robust granular material. Even when the substance is put into water, it does not disintegrate and disperse, and it deposits on the bottom of the water, and cannot function as a wettable powder. The present inventors have conducted various studies to produce a granular wettable powder having good rain resistance while maintaining good disintegration dispersibility. As a result, the granular wettable powder produced by a conventional method is fixed in a powder form. The inventors have found that a preparation obtained by mixing with an agent and dressing it can achieve this object, and completed the present invention.
本発明における固着剤は、農園芸分野で通常に使用さ
れているものであつて、耐雨性を付与しうるものであれ
ば何ら限定はない。このような固着剤としては、たとえ
ばポリビニルアルコール、カルボキシメチルセルロース
もしくはそのナトリウム塩、ヒドロキシプロピルセルロ
ース、ヒドロキシプロピルメチルセルロース、ポリエチ
レングリコール、ポリプロピレングリコール、アルギン
酸ナトリウム、カゼインナトリウム、アラビアゴム、ゼ
ラチン、アルフアー化デンプンまたはジアルキルスルホ
こはく酸ナトリウム等があげられる。The sticking agent in the present invention is one that is commonly used in the field of agriculture and horticulture, and is not limited as long as it can impart rain resistance. Examples of such a fixing agent include polyvinyl alcohol, carboxymethyl cellulose or a sodium salt thereof, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, polyethylene glycol, polypropylene glycol, sodium alginate, sodium caseinate, acacia, gelatin, alphaure starch or dialkyl sulfo. Examples include sodium succinate.
顆粒水和剤に粉衣される固着剤の量は、通常、最終製
剤の0.1ないし５重量部程度である。The amount of the sticking agent coated with the wettable granules is usually about 0.1 to 5 parts by weight of the final preparation.
固着剤は、粉衣後に顆粒水和剤から容易に剥離しない
ことが望ましく、そのために、固着剤の平均粒径が0.3m
m以下であることが好ましい。It is desirable that the adhesive does not easily peel off from the wettable granules after dressing, and therefore the average particle size of the adhesive is 0.3 m.
It is preferably m or less.
顆粒水和剤への固着剤の粉衣は、常法により、両者を
10分〜30分程度、ナウターミキサー等の慣用の混合機中
で撹拌混合することにより容易におこなうことができ
る。For the coating of the adhesive to the wettable granules,
It can be easily carried out by stirring and mixing in a conventional mixer such as a Nauta mixer for about 10 to 30 minutes.
このようにして得られる、固着剤が粉衣された顆粒水
和剤を水中に投入すると、顆粒水和剤は容易に崩壊し分
散して、安定な懸濁液を生成する。When the thus obtained granular wettable powder coated with a fixing agent is put into water, the wettable granule easily disintegrates and disperses to form a stable suspension.
このことは意外なことである。何故ならば、顆粒水和
剤を被覆する固着剤は、製剤時の混合撹拌により顆粒と
緊密に接触しており、水中への投入時に顆粒から容易に
離脱することなく、水との接触により水和した皮膜を顆
粒の表面に形成し、その結果顆粒は崩壊分散することな
く水底に沈積することが容易に予想されるからである。This is surprising. This is because the sticking agent that coats the wettable granules is in intimate contact with the granules by mixing and stirring during the formulation, and does not easily separate from the granules when it is put into water, so that it does not come out of contact with water when contacted with water. This is because it is easily expected that a soaked film is formed on the surface of the granules, and as a result, the granules are not disintegrated and dispersed but are deposited on the water bottom.
このように、本発明による、固着剤で表面が粉衣され
た顆粒水和剤は、薬液の調製時の性状および調製後の懸
垂性が、固着剤が粉衣されていない対照の顆粒水和剤と
ほぼ同程度に保たれており、しかも薬液を植物体に散布
したとき、耐雨性が格段に改善されている。Thus, the granular wettable powder according to the present invention, the surface of which is coated with a sticking agent, has the properties during preparation of the drug solution and the suspending property after the preparation, and the sticky agent is not coated with the granule hydrate of the control. It is maintained at about the same level as the agent, and when the chemical solution is sprayed on plants, the resistance to rain is significantly improved.
