Abstract

Abstract A composition, a concentrate of said composition and a method for inhibiting the growth of a fungus which is capable of growth over a non-nutrient surface which comprises treating the fungal mycelium or a foodbase on which the mycelium is capable of growing with a nitrogenous substance selected from those substances which are either translocated within the mycelium or taken up by the mycelium or both taken up and translocated and which are not utilized by the fungus for growth when said substance is the sole source of nitrogen supplied to the fungus.
