Abstract

Abstract Not Available – First paragraph follows: Fireblight, caused by the bacterium Erwinio amylovora, is an erratic and devastating disease of pear orchards. Native to North America, it was first observed in California in the 1890s after slowly crossing the continent from the east, decimating pear orchards in its path. Fireblight has the potential to destroy an established orchard in one season if uncontrolled. With 37,440 acres of hearing trees producing a crop of 353,500 tons valued at $44 million, California pear producers have traditionally spared little in their protection efforts to keep the disease in check.
