Pitch Canker, Fusarium circinatum, is a disease that affects pines. Particularly of importance in California is the endemic Monterey Pine, Pinus radiata. One aspect of the study was to determine if there is a relationship between age and severity levels on pitch canker infested Monterey Pines corresponding to water stress. The other focus of the study was to see how age is affected by pitch canker, as associated by severity level. Monterey Pine survey data from 2000-2001 was collected by Asilomar State Park ecologists and used to determine pitch canker presence and water stress samples were obtained. No statistically significant results were formulated from the water stress samples, however age was found to be dependent on severity level (or vice versa). The implications of these results pertaining to water stress, age susceptibility, and future management of pitch canker are discussed.
