The influence of inoculum density and environment on the development of potato blackleg

American Potato Journal, 1978
Significant increases in pre-emergence seedpiece decay and preemergence shoot infection were observed asErwinia carotovora var.atroseptica inoculum density increased. As inoculum density increased, a point was reached where virtually 100 per cent of the disease was expressed as preemergence decay and no typical postemergence blackleg occurred.

Effect of inorganic fertilizers on the Incidence of potato blackleg disease

European Potato Journal, 1966
In assessing disease levels in a number of potato fertilizer trials in south-east Scotland it was found that an increase in the rate of application of complete fertilizer or nitrogen alone resulted in a decrease in the proportion of stems affected by potato blackleg.

Potato blackleg: Epidemiology, host-pathogen interaction and control

Netherlands Journal of Plant Pathology, 1992
Blackleg is caused byErwinia carotovora subsp.atroseptica (Eca) andE. chrysanthemi (Echr) in cool and hot climates respectively. The bacteria are opportunistic pathogens and rely on their strong pectolytic character to infect plants when conditions favor their multiplication.
