Almond Ganoderma Butt Rot Spore Survey

Ganoderma butt rot has been an increasing problem in the almond industry. The disease has been responsible for trees falling over all throughout the Central Valley. Ganoderma butt rot is caused by wood decay fungi that can spread via spores in the air. In order to better focus our management efforts, researchers must conduct a spore survey that will help us determine the times and locations that are at greatest risk of infection and spread by spores.

The survey will include collecting air samples at almond orchards once a month for 2 years, so it will require long-term cooperation, but will be non-invasive and will not interfere with management practices. Any almond growers interested in volunteering their orchards (any age orchard works) for the research conducted by UC Davis plant pathologists, please contact Daisy Hernandez.

Thank you all for your time and help.

    Regarding butt and other basal rots, we still see too many trees that are repeatedly wetted by micro sprinklers, leading to basal wood rots and premature tree failure. There are simple solutions to avoid this and thus reduce internal wood rots and loss of trees otherwise in their prime.
