Abstract
Phaeocytostroma ambiguum is reported for the first time in New South Wales associated with root and stalk rot of maize plants near Darlington Point in the Riverina district. Symptoms observed on field-infected plants were reproduced on the roots of seven maize hybrids, inoculated with pure cultures of P. ambiguum and grown under glasshouse conditions. The hybrid 108/7222 showed significantly less root infection than the hybrids 766/6213, 797/7529 and 925/7323. Typical symptoms of stalk rot were also reproduced on the artificially inoculated hybrids except for 108/7222 and 797/7529, which appeared to be resistant to stalk infection.
