PURPOSE: A controlling agent against miscellaneous algae, containing (3-amino-3- carboxylpropyl)-methyl phosphinic acid and salt thereof as an active ingredient and capable of controlling noxious miscellaneous algae contaiminating in artificial cultivation without damaging the conchocelis phase of laver.
CONSTITUTION: A controlling agent containing (3-amino-3-carboxypropyl)- methylphosphionic acid and a salt thereof, e.g. ammonium, Na or K salt, as an active ingredient. The agent in an amount of 10W500ppm, preferably 50W200ppm expressed in terms of the active ingredient based on seawater is added to a cultivation tank to effectively control noxious green algae, diatom, blue-green algae, etc., growing in cultivation seawater and sticking onto shells, promote growth of conchocelis phase and prevent the contamination of seawater.
