Abstract
Pythium tracheiphilum, the cause of lettuce stunt, wilt and leaf blight, was recorded for the first time in Australia in July 2005, on gourmet lettuce at two farms at Gingin, near Perth, Western Australia. A subsequent survey of commercial lettuce crops failed to find symptoms of lettuce wilt and leaf blight at additional properties, and P. tracheiphilum was not isolated. P. tracheiphilum was, however, isolated from chicory from two home gardens, one at Fremantle, and one at Beaconsfield, near Perth, in September 2005.
