What does the published scientific research say about Pseudozyma flocculosa?

Eight PubMed articles address Pseudozyma flocculosa in a plant-input context, consistently characterizing it as a biocontrol agent (BCA) of powdery mildews (Erysiphales). The peer-reviewed literature describes this epiphytic yeast as a natural phyllosphere inhabitant with specific antagonistic activity against powdery mildew fungi — making Pseudozyma flocculosa powdery mildew biocontrol a well-documented area of applied mycology research.

Ecological work cited in the literature identifies a zinc/manganese complex on powdery mildew colonies as a key nutritional driver of P. flocculosa's specificity toward Erysiphales, distinguishing it from related fungi such as Ustilago maydis. Molecular ribosomal DNA markers can distinguish P. flocculosa from other Pseudozyma species and resolve distinct strains — relevant to product identity in research and regulatory contexts. One review notes Canadian programs developing P. flocculosa specifically for greenhouse powdery mildew management.
