Abstract

First report of white mould caused by Sclerotinia sclerotiorum on pea in Bangladesh.

Abstract

Pea (Pisum sativum) is one of the important winter-season legume crops in Bangladesh. In January 2018, farmers' fields in Chapainawabganj district were surveyed for pea diseases. Tan to light brown blighted stems and pods were detected in 2.6% of plants with an average disease severity rating of 3.7. Prominent dark sclerotia (3.5-14.8 Ă— 1.9-5.3 mm) were found on the surface of the infected tissues or were embedded within the tissues. The causal pathogen was isolated and identified as Sclerotinia sclerotiorum based on morphological characteristics, molecular data (sequence analysis of the ITS region) and pathogenicity test. This is thought to be the first report of mould caused by S. sclerotiorum on pea in Bangladesh.
