Matteo Garbelotto, assistant adjunct professor in the Department of Environmental Science at UC Berkeley, will lead the training session.
The pathogen that causes SOD spreads most often on infected California bay laurel leaves, said Kathy Hughes Anderson, Atherton's town arborist. The May 21 meeting is a SOD "blitz," she said, designed to involve volunteers in detecting the disease and producing local maps of disease distribution.
Meeting participants will be trained in collecting samples of bay leaves for diagnostic testing.
