PROBLEM TO BE SOLVED: To prepare an antifungal sand which can control eluation of metal ions by selectively using an inorg. carrier for carrying an antifungal metal ion, a fixing and coating agent and additionally, a curing agent during calcining in preparing the antifungal sand with antifungal action and plant germination inhibiting action. SOLUTION: Inorg. particulate bodies having silicon dioxide as a main ingredient are coated with at least one antifungal metal ion selected from silver, copper and zinc. Then, they are fixed by using an alkali silicate and furthermore, calcining is performed by using SiO2 .nAl2 O3 (n=0.06-0.10) as a curing agent. |
