Plant Protection Clayson, Shane P. [1], Miller, Jeff S. [1]. Evaluation of inoculation, wounding and storage temperatures for post-harvest pink rot development. INCREASING zoospore inoculum of Phytophthora erythroseptica (Pe, cause of pink rot of potato) requires extensive effort and time. Since zoospores are short-lived, it is crucial that tuber inoculation and storage procedures are optimized for infection and experimental efficiency. The objective of this experiment was to evaluate the impact of inoculation method, wounding, and storage temperature on pink rot development in Russet Burbank tubers. The experiment was conducted as a 3x2x2 factorial with the factors of inoculation method (30,000 zoospore/ml applied by tuber dip, inoculum spray, or by filter paper applied to terminal bud), wounding (2 min tumble in padded cement mixer or non-wounded), and temperature (16 or 21C). Tubers were stored in sealed plastic bags for 10 days then evaluated for pink rot incidence. The trial was repeated. The interaction among inoculation, wounding and temperature was significant. At both temperatures, wounded tubers inoculated by dip and spray had significantly (P
