機物に付着して汚損を生じる。Problems caused by large amounts of algae are occurring in many areas. For example, when blue-green algae forms in tap water, a musty odor is generated, and when diatoms adhere to heat exchange equipment such as building cooling towers, heat exchange performance deteriorates. In addition, when green algae or blue-green algae occur in fish tanks or aquaculture ponds, eutrophication causes oxygen deficiency, deterioration of water quality, and red tide. Furthermore, if the water supply system for industrial water is clogged, 1-C (1-C) in the water will adhere to equipment such as fishing nets and the bottom of ships, causing stains.

に及ぼす影響にも多くの問題を抱えている。Conventionally, many substances have been developed as anti-algae agents and algaecides to suppress or kill algae growth.
Those mainly composed of inorganic metals such as tin compounds and copper compounds,
Antibiotics, organic synthetic products such as sulfonimide derivatives, etc. have been proposed. However, these cannot be said to be sufficiently safe for the human body when used in large quantities, and there are many problems with the impact they have on the ecosystem of the environment in which they are used.

れも効果の点で十分とは言い難い。On the other hand, attempts have also been made to use plant extracts, which are said to be highly safe and have excellent biodegradability, as antialgae agents. For example, octadecatetraenoic acid contained in the brown alga Okinawa Mozuku is used as an algae removal agent (Japanese Patent Application Laid-Open No. 63-10704), and Japanese knotweed is used as an underwater antifouling agent (Japanese Patent Application Laid-Open No. 63-316707). , same 6
No. 2-77306), using cashew nut oil as a repellent for organisms attached to water (Japanese Patent Application Laid-Open No. 1-96102)
Publication No.) etc. have been reported. However, none of these can be said to be sufficiently effective.
このように、効果、安全性、環境保全の総ての要求を満
たす抗藻剤は未だ開発されておらず、現在なお様々な方
面からの検討が続けられている。As described above, an antialgal agent that satisfies all the requirements of effectiveness, safety, and environmental conservation has not yet been developed, and studies are still being conducted from various angles.

本発明の抗藻剤組成物は、タンニン含有物と有機酸とを
併用してなることを特徴とする。The antialgae composition of the present invention is characterized by containing a tannin-containing material and an organic acid in combination.
以下、本発明についてさらに詳細に説明する。The present invention will be explained in more detail below.

たタンニン含量の高い分画物として使用できる。As the tannin-containing material of the present invention, tannin-containing raw materials such as tannin-containing plants (including seaweed, plant-derived herbal medicines, etc.) are used raw or dried, or extracted with a solvent. It can be used as an extract and, if necessary, as a fraction with a high tannin content obtained from the extract by fractionation using a column or the like.

If the amount of organic acid blended is too small, the antialgae effect may not be sufficiently exhibited. On the other hand, if the amount of organic acid is too large, it may have an adverse effect on aquatic organisms due to acidification of the pH.

使用上の安全性、生分解性も極めて良好である。Look! According to the antialgae composition of the present invention, by using a tannin-containing substance and an organic acid together, both components act synergistically to significantly inhibit the growth of microalgae such as blue-green algae and diatoms. It suppresses algae and exhibits excellent anti-algae effects when used in small amounts. Moreover, since the tannin content is a natural product extracted from plants,
It is also extremely safe in use and biodegradable.
