Resistance of Cucurbits to Podosphaera xanthii Race 1 [PDF]

Horticultural Science and Technology, 2014
This study was conducted to establish an efficient screening method to identify cucurbits resistant to powdery mildew. Powdery mildew fungus was obtained from a single lesion of infected cucumber leaf in 2010 at Daejeon. The fungus was identified as Podosphaera xanthii race 1 based on morphological characteristics and resistance responses of four melon

First record of Podosphaera xanthii on Peperomia tetragona [PDF]

Australasian Plant Disease Notes, 2017
In January 2017, Peperomia tetragona was found to be infected with a powdery mildew in Korea. No chasmothecia were observed. The fungus associated with foliar signs of powdery mildew was identified as Podosphaera xanthii using morphological characteristics of the anamorph and molecular analysis of ITS regions. This is the first report of powdery mildew
