An Examination of Apple Powdery Mildew and the Biology of <i>Podosphaera leucotricha</i> from Past to Present

Abstract

Within is a comprehensive review of current apple powdery mildew literature, with the taxonomy, morphology, and life cycle of the causal phytopathogen Podosphaera leucotricha described. A discussion of economic impact, environmental aspects contributing to apple powdery mildew epidemiology, options for cultural, chemical, and biopesticide disease control, and fungicide resistance in P. leucotricha is also detailed. The present status of breeding for host resistance and apple cultivar susceptibility is discussed. Finally, emerging research into the biology and management of apple powdery mildew is discussed along with how they may aid future research endeavors.
