New R&D Report - Psa-V leaf spots as inoculum sources

04 September 2014

This project has shown leaf spots continually produced inoculum between November 2013 and March 2014. Under humid conditions, even ‘old’ leaf spots were capable of producing ooze at the edge of the lesion, containing large numbers of viable bacteria. Thus, leaf spots are a continual source of Psa inoculum during the spring and summer seasons.
