Description
Field experiments were conducted at Live Oak, Florida, and Rhodesdale, Maryland, to evaluate the effect of variable seed-borne inoculum load of Dickeya dianthicola on potato plant emergence, plant growth throughout the growing season, disease prevalence in the field throughout the growing season, yield and grade, and transmission of D. dianthicola to progeny tubers. No statistically significant differences in emergence, plant height, or disease incidence were observed at either location. Statistically significant differences were observed in yield at the Florida location; all inoculated treatments had significantly lower yield than the non-inoculated control. No significant differences in yield were observed among treatments at the Maryland location. No significant differences in grade were observed at the Florida location. Significant differences in one tuber profile category were observed at the Maryland location. No significant differences in transmission of D. dianthicola to progeny tubers were observed at the Florida and Maryland locations.
