In May 2022 symptomatic leaves were detected on Cotoneaster pannosus (Silverleaf Cotoneaster) in Marin County, California (37.89165, -122.

- The Sudden Oak Death Blitzes are annual citizen-led surveys mapping the spread of Sudden Oak Death (SOD) in northern California, which discovered possible symptoms in six rare manzanita species for the first time.
- During the studies, symptoms such as branch cankers and canopy mortality were observed, and researchers confirmed through inoculation experiments that these species can host the SOD pathogen.
- Additional manzanita species were later examined, showing varying susceptibility to the disease, with findings indicating that even low levels of spore production could lead to localized contagion, especially in wet conditions.
Pinus radiata (Monterey pine), a tree native to coastal California and Mexico, is widely planted worldwide for timber production. A major threat to Monterey pine plantations is the fungal disease pine pitch canker, caused by Fusarium circinatum (Hypocreales). We present a novel trapping approach using filter paper in combination with a rapid molecular method to detect the presence of inoculum in the air.
