Abstract

First report of botrytis blight caused by Botrytis cinerea on Paeonia lactiflora in Serbia.

Abstract

Peony (Paeonia lactiflora) plants cv. Sarah Bernard with leaf blight were observed in two home gardens located in Jagodina, central Serbia. Disease severity (percentage diseased leaf area) was approximately 15% and the disease incidence was 70%. Symptoms were characterized as small, brown spots that first appeared on the leaf margin, spreading gradually to the interior of the leaf, forming irregularly shaped spots. Based on morphological characteristics, molecular data (sequence analysis of the rDNA internal transcribed spacer region and nuclear protein-coding genes) and a pathogenicity test, the causal agent was identified as Botrytis cinerea. Botrytis blight on P. lactiflora was previously reported in the USA, Iran, China and Chile. This is thought to be the first report of Botrytis blight caused by B. cinerea on P. lactiflora in Serbia.
