Abstract

First report of alternaria leaf spot caused by Alternaria tenuissima on blueberry (Vaccinium corymbosum) in Western Australia.

Abstract

Blueberry (Vaccinium corymbosum) plants in a commercial plantation at Yanchep, Western Australia, Australia, in April and May 2013, showed a widespread leaf spotting condition. Leaf lesions were circular to irregular, light brown to grey, 1-5 mm in diameter, with distinct dark brownish red borders. The causal pathogen was identified as Alternaria tenuissima based on morphological, genetic (ITS) and pathogenicity analyses. This is thought to be the first record of A. tenuissima on V. corymbosum in Western Australia, Australia.
