Abstract

First report of Botrytis cinerea causing gray mold of Peperomia ferreyrae in Jilin Province, China.

Abstract

In March 2016, symptoms of an unknown blight were observed on thousands of potted Peperomia ferreyrae plants grown in a greenhouse of the Changchun Agriculture Exposition (Jilin, China) with 50-70% incidence. Early symptoms appeared as small, round or elliptical, brown lesions on leaf surfaces. After lesions spread to the leaf axils, abscission occurred. Subsequently, stems became infected resulting in a water-soaked, brown soft rot. The causal pathogen was identified as Botrytis cinerea based on morphological, molecular and pathogenicity analyses. This is thought to be the first report of B. cinerea causing grey mold disease on P. ferreyrae in Jilin, China.
