Abstract
PURPOSE: A selective controlling agent having destroying action on purankutons poisonous to shellfishes and no bad influence upon useful purankutons which are nutrient sources for shellfishes, comprising sodium percarbonate as an active ingredient.
CONSTITUTION: The titled controlling agent comprising sodium percarbonate, a water-soluble white solid, obtained by reacting sodium carbonate with H2O2, as an active ingredient. In the amount of sodium peroxide, for example, a concentration 10ppm can prevent the growth of gonyaulax catenella funkawan. A concentration 50W100ppm can destroy it almost completely. While, this concentration will not have bad influence upon useful purankutons, e.g., Dunalliella tertiolecta, etc. The sodium peroxide is directly scattered in the occurrence area of purankutons poisonous to shellfishes or in the vicinities of the distribution area of shellfishes or after it is blended with a proper carrier or auxiliary, granulated or molded for use.
