Abstract
Powdery mildew is a common disease on Coreopsis lanceolata,which affects the growth and deve-lopment of the plant and reduces its ornamental value.From 2022 to 2023,powdery mildew occurred seriously on Coreopsis lanceolate in Beijing.In this study,typical morphological characteristics of the pathogenic isolates were analyzed,and a phylogenetic tree was constructed based on the ITS sequence.The results showed that the isolates were identified as Podospaera fusca.This is the first report of Coreopsis lanceolata powdery mildew in Beijing,which will contribute to the control of powdery mildew on Coreopsis lanceolata.
