Abstract
A conspicuous leaf scorch of wheat associated with Didymellaceae family was observed on commercial wheat varieties in Western Australia during recent years. Two fungal species isolated from leaf lesions were identified based on morphological characteristics and DNA sequencing. Neoascochyta europaea was isolated from symptomatic leaf lesions on the wheat varieties Trojan and Wyalkatchem also Neoascochyta graminicola was detected on Calingiri variety. Pathogenicity tests were conducted and Koch’s postulates were fulfilled by reisolating of these fungal species. This is a first report of Neoascochyta europaea and Neoascochyta graminicola causing leaf scorch on wheat in Australia.
