Abstract
Plant pathogenic fungi belonging to the genus Phytophthora such as phytophthora cinnamomi which causes root rot in plants is biologically controlled with strains of fungi belonging to the genus Myrothecium. Preferred strains of Myrothecium are Myrothecium roridum ATCC 20963, 20964 or 20965. An inoculum containing Myrothecium and a substrate such as bran or a branalginate mixture is added to the surface of a plant or to soil. The Myrothecium may be grown on the substrate 5 to 7 days before use of the inoculum.
