What was it all about?

Pathology testing and a copper spray trial had been the mainstays of the bubbly bark investigation at the time. Chestnut trees and plant and soil material had been sent to Crop Health Services to investigate whether a principle pathogen could be isolated from material collected during the growing period. A budding trial was carried out to discover if infection was entering during the budding process.

Dr S Chin Gouk (Senior Plant Pathologist, DPI, Tatura) became involved in the search for greater understanding of chestnut bubbly bark.
