Abstract

Pseudomonas savastanoi pv. savastanoi was identified as the cause of galling on olives (Olea europaea), cv Barnea in South Australia in May 2003 from a property at Greenfields ≈10 km north of Adelaide. The bacterium was recovered from galls on 2-year-old olive trees (cv. Barnea) showing symptoms consistent with those attributed to olive knot. Following a targeted survey of cv. Barnea, further infections were located on 2 to 5-year-old trees in four other plantings in South Australia. This is the first record of olive knot in Australia.
