PURPOSE: To obtain a controller for organism of fouling algae and mosses of artificial lawn, capable of destroying fouling organisms in artificial lawn or artificial lawn having sand fouled by algae and mosses, having removing action and low toxicity.
CONSTITUTION: A chlorine dioxide-based compound in an amount of 0.1-5.0% calculated as effective chlorine as a main agent is mixed with 0.1-10 times as much an effect enhancer as the main agent to provide a highly concentrated solution, which is sprayed upon artificial lawn in a large amount of 0.5-5 liters per m2 to give destroying effects on algae and mosses only by its instant contact. Further, about the time of spray of the bleaching solution, separately a peroxide-based bleaching agent as an effect enhancer is applied to artificial lawn so that bond of algin water-soluble viscous polysaccharide of unicellular aggregation, namely hormogonium, of algae among target algae and mosses is loosened to widen a space interval, to assist contact action of an aqueous solution of the bleaching agent of a chlorine-based compound and to increase destroying effect on algae. Addition of alum or an aqueous solution of aluminum poly chloride strengthens killing force of mosses by its astringency, aggregation and increase in viscosity of a chemical solution. Furthermore, increase in viscosity and endowment of basicity by addition of water glass saves the chlorine dioxide-based compound of the main agent, reduces toxicity and enhances killing effects on algae and mosses.
