A novel soil-less method was developed to define susceptibility
of developing potato tubers accurately to
infection with Streptomyces scabiei the causal agent of
common scab disease. Hydroponic production enabled
precise identification of individual tuber development.
Direct inoculation of tubers with a spore suspension of
S. scabiei resulted in disease development, demonstrating
that infection could be initiated in a soil-less
media. Tubers were most susceptible to infection
between 3 and 20 days after tuber initiation, confirming
that this early period of tuber formation is critical
to disease development
