Cucurbit Powdery Mildew Population Virulence Variation – a Complex View from a Global Perspective

Cucurbit powdery mildew (CPM) is mainly caused by two obligate ectoparasites, Golovinomyces orontii s.l. (Go) and Podosphaera xanthii (Px), that are highly variable in virulence. Various independent systems of CPM race determination and denomination have been used in recent decades. We recently developed new tools to enhance research of CPM virulence variation. Diversity models were […]

Podosphaera xanthii but not Golovinomyces cichoracearum infects Cucurbits in a Greenhouse at Salinas, California

Cosme Bojorques Ramos Karunakaran Maruthachalam, James D. McCreight Raymundo S. Garcia Estrada Traditionally, Erysiphe cichoracearum (now Golovinomyces cichoracearum) and Podosphaera xanthii, formerly Sphaerotheca fuliginea, have been reported as the causal agents of cucurbit powdery mildew (CPM) (2, 10). These two fungal species have often been misidentified (12), due to similarities in their anamorphic characteristics and […]
