Abstract

First report of Phoma glomerata associated with the ascochyta blight complex on field pea (Pisum sativum) in Australia.

Abstract

In September 2012, from a field pea disease screening nursery at Medina, Western Australia, Australia, approximately 1.0% of isolates were a Phoma sp. morphologically different to any Phoma sp. previously reported on field pea in Australia. Diseased plants exhibited symptoms including ascochyta blight, foot rot and black stem and leaf and pod spot. The causal pathogen was identified as Phoma glomerata based on morphological, genetic (ITS) and pathogenicity analyses. This is thought to be the first report of P. glomerata as a pathogen on field pea in Australia.
