Epidemiology of disease caused by Pseudomonas syringae as an epiphyte and its frequency, distribution, and characteristics as an endophyte of pear

Creator:: Whitesides, Steven K.
Abstract:: Conditions were established for inducing pear blossom blast caused by Pseudomonas syringae (Ps) on both attached and detached shoots. The incidence of disease was proportional to the log of Ps population under optimal temperature, moisture and bloom developmental stage. Highest incidence of infection followed occurrence of a major exotherm in...
