Application of lime as 1:1 Ca(OH)₂ : CaCO₃ to raw soil, and to soil either before or after autoclaving, resulted in the production of fungistatic volatile(s). The volatile factor(s) could be induced in a slightly acid aqueous soil extract made alkaline by lime or tris(hydroxymethyl)aminomethane (tris) solution in the absence of any culturable organisms.
