The growth of edible seaweeds, especially red algae such as Norifolia and Norifolia, is inhibited by pathological bacteria and microorganisms. Typical diseases of nori include pot-shaped fungal disease and red rot due to intracellular parasitism of pathological bacteria, as well as filamentous bacterial enthesis and dota rot due to adhesion of bacteria and algae to the leaf surface. etc. These diseases occur almost every year and cause great damage to seaweed aquaculture.

Conventionally, the following methods have been used to control these diseases. In other words, for pot-shaped fungal disease, early plucking or removal of diseased leaves (no effective chemotherapy is known yet), and for red rot, prolonging the drying time, freezing treatment, and acid treatment. Treatment with seawater or high-salinity seawater, and for stain rot, drying, freezing, or treatment with acidic seawater are performed.

When using the disease control agent of the present invention, first, the basic principle is added to seawater to prepare alkaline seawater. In this case, the alkaline compound (A) and, if desired, the metal compound (B) can be added to the seawater directly or in the form of an aqueous solution. Next, the seaweed is immersed in the alkaline seawater obtained, or the seaweed is sprayed with this seawater. The pH value of alkaline seawater is generally 9 or more, preferably from 9 to 13 when ammonia is used as the compound (A), and from 10 to 14 when other compounds (A) are used. If the pH value is lower than 9, the desired control effect will hardly be obtained. Spraying is generally done at sunrise, and after a certain period of time has elapsed after spraying,
The treated seaweed is returned to seawater. The immersion time and sunrise time are determined by the type of alkaline compound used and its concentration or pH value in seawater. Metal compounds (

25100.00 Test Example 1 Sodium hydroxide was added to seawater to prepare alkaline seawater exhibiting various pH values. The pH value was measured by a glass electrode method. The pH value of seawater without the addition of sodium hydroxide was 8. In these alkaline seawater, the laver fronds and the laver fronds infested with pot-shaped fungi, red rot fungi, and filamentous bacteria were immersed for a predetermined period of time. In order to examine the resistance of the glue leaves and pathological bacteria to alkaline seawater, the degree of damage to the glue and the amount of bacteria attached were measured by microscopic observation or erythrosin staining (dead cells in the glue are stained) before and after immersion. After immersion, the cells were cultured for an additional 10 days under normal conditions, and the presence or absence of disease progression was investigated.
