Algae inhibitor, method for producing algae inhibitor and algae inhibition method

Abstract

The present invention relates to: an algae inhibitor, which is to be floated on water so as to inhibit algae floating thereon, characterized by comprising at least an algaecide component comprising lysine or a lysine salt and malonic acid or a malonic acid salt, a core agent which contains a binder for carrying the algaecide component, and a coating agent which exists on the surface of the core agent and controls the sustained release properties of the algaecide component; a method for producing the algae inhibitor; and an algae inhibition method. The binder is preferably a component selectedfrom the group consisting of "polymers derived from natural materials" and "materials causing no environmental pollution".

Description

technical field

[0001] The present invention relates to an algae inhibitor having at least a core agent containing a specific medicinal ingredient and a coating agent, a method for producing the algae inhibitor, and a method for inhibiting algae. Background technique

[0002] In recent years, in water environments such as lakes, marshes, and reservoirs, algal blooms such as blue-green algae have caused problems such as destruction of ecosystems, odor, and deterioration of water quality. In particular, blue-green algae and the like produce toxic substances, and there have been reports of death of not only a large number of aquatic animals but also land animals. In addition, blue-green algae and the like float on the water surface during sunshine and reproduce by photosynthesis, so they block the light path to the water and hinder the photosynthesis of other photosynthetic organisms. Stay in the water for respiration after sunshine, thereby absorbing the dissolved oxygen in t...
