Abstract: The present invention describes substantially pure cultures of three new species of fungi, Meira geulakonigae (CBS 110052), Meira argovae (CBS 110053) and Acaromyces ingoldii (CBS 110050) (all nom. prow.), wherein said cultures are biologically pure. The conditioned medium for all three new fungi species is also described, as well as their biologically active products. The biological product of the three new fungi species and their conditioned medium has miticidal and fungicidal activities. Thus, a composition for the control of mites and/or phytopathogenic fungi comprising a biocontrol agent derived from any one of the three new fungi species is also described, optionally comprising an agriculturally compatible carrier. Finally, the present invention describes a method for producing a fungicide and/or a miticide, wherein the active ingredient of said fungicide/miticide is any one of M. geulakonigae, M. argovae, or A.

Abstract: Oomycete-caused plant disease, e.g., downy mildew, is controlled using Fusarium proliferatum, and biologically pure cultures of Fusarium proliferatum strains G6, M3, C51 and C173 respectively having accession numbers ATCC 74149, ATCC 74273, ATCC 74274 and ATCC 74275 are provided.

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.
