Description

Transplanting panel of hydroponics treated with silver zeolite containing polymer emulsion prevented root incursion and algae growth on transplanting panel. Algae growth on expanded polystyrene transplanting panel was inhibited by a coating treatment with silver-zeolite containing polymer emulsion. Treatment of 800 ppm of silver zeolite containing polymer emulsion was more effective than 400 ppm of silver-zeolite containing polymer emulsion for the suppression of the algae growth on panels. Silver-zeolite containing polymer emulsion also prevented incursion of mitsuba root incursion to the expanded polystyrene transplanting panel. Growth suppression was not found on mitsuba seedlings transplanted on silver-zeolite conteinning polymer emulsion treatment of the expanded polystyrene transplanting panel. Microorganism populations decreased significantly surface of the panel treated by the silver-zeolite containing polymer emulsion, while they had no effect in the hydroponics cultural solution.<br>
