Disease on Nursery Stock as Affected by Environmental Factors and Seasonal Inoculum Levels of Phytophthora Ramorum in Stream Water Used for Irrigation

Tjosvold, S. A., Chambers, D. L., Koike, S. T., and Mori, S. R. Plant Disease 92(11):1566-1573. 2008.

A pear bait monitoring system was used to detect and quantify Phytophthora ramorum propagules in streams that flow through woodland areas with sudden oak death in Santa Cruz County, CA from 2001 to 2007. Stream propagules were detected most frequently or occurred in highest concentrations in winter and spring. The stream propagule concentration was characterized with statistical models using temperature and rainfall variables from 2004 to 2007.
