ABSTRACT:
A novel fungal strain of the species Ampelomyces quisqualis has been isolated and pure cultures thereof prepared. This novel strain is termed AQ10 and has CNCM Accession Number I-807, and was found to be a hyperparasite of the causative fungi of powdery mildew. Conidia obtained from this novel strain or mutants thereof may be formulated into phytological compositions and used effectively as a biocide for controlling powdery mildew infestations.
