本発明は、壷状菌に対して優れた作用を有するアマノリ

効果を示す殺菌剤を開発するため研究を重ねた結果、本
発明を完成した。Sea laver farming has already been around for several decades, and although farming techniques are progressing and improving year by year, there are still insufficient measures against diseases, and the damage caused is enormous. In particular, if a parasitic disease called pot fungus spreads, production may be completely eliminated. Nowadays, pot-shaped fungus disease occurs every year and causes a lot of damage, so there is a demand for the development of a pot-shaped fungus control agent. The present inventor completed the present invention as a result of repeated research to develop a disinfectant that is highly safe and exhibits excellent effects against pot-shaped bacteria.
本発明は、安息香酸、これを酸性溶液に乳化するための

ノリ用殺菌剤である。The present invention is a fungicide for laver, characterized by containing benzoic acid, an emulsifier for emulsifying benzoic acid in an acidic solution, and an emulsion stabilizer.

ｐＨ３以下の酸性溶液中で安息香酸な乳化することが困
難である。Benzoic acid is poorly soluble in acidic solutions and forms a precipitate. As the emulsifier used for emulsifying in an acidic solution such as benzoic acid, for example, polyoxin rubitan ester or polyglycerin fatty acid ester is preferable. If other emulsifiers are used, such as gelatin, casein, sodium oleate, sucrose fatty acid esters or sodium laurate,
It is difficult to emulsify benzoic acid in acidic solutions with pH below 3.

等が用いられる。Various emulsion stabilizers can be used, but partially saponified polyvinyl alcohol is particularly preferred. This polyvinyl alcohol is usually used after being dissolved in water. Since benzoic acid has strong sterilizing power in an acidic range, it is preferable that the sterilizing agent of the present invention contains another acid. The acid may be either an organic acid or an inorganic acid (eg, phytic acid, phosphoric acid, hydrochloric acid, citric acid, malic acid, fumaric acid, etc.).
本発明の殺菌剤を製造するに際しては、安息香酸に乳化

塩を用いることもできる。When producing the disinfectant of the present invention, an emulsifier, an emulsion stabilizer, water and, if desired, an acid may be added to benzoic acid, and the mixture may be thoroughly stirred. As benzoic acid, its salts such as sodium salts can also be used.

Parts by weight. The amount of emulsion stabilizer used is 1 benzoic acid.
The amount is 0.5 to 4 parts by weight. If the amount of the emulsifier and emulsion stabilizer used is less than this, it will be difficult to emulsify in an acidic solution, and even if the amount used is larger than this, no particular improvement in the effect will be observed.

い。When using the fungicide of the present invention, add seawater to prepare a diluted solution with a benzoic acid concentration of 100 to 500 ppm and a pH of 3 or less, and add one laver culture net to this diluted solution.
It is preferable to soak for ~20 minutes. Alternatively, the diluted solution may be sprayed onto the aquaculture net. The treated aquaculture net can be used for aquaculture as is. In addition, when the pH of the diluent is higher than 3, it is preferable to add an acid to adjust the pH to 1 to 3.
