First report of the white pine blister rust pathogen, Cronartium ribicola, in Arizona


Fairweather, M. L.; Geils, B. W. 2011. First report of the white pine blister rust pathogen, Cronartium ribicola, in Arizona. Plant Disease. doi: I: 10.1094/PDIS-10-10-0699.

White pine blister rust, caused by Cronartium ribicola J.C. Fisch., was found on southwestern white pine (Pinus flexilis James var. reflexa Engelm., synonym P. strobiformis Engelm.) near Hawley Lake, Arizona (Apache County, White Mountains, 34.024°N, 109.776°W, elevation 2,357 m) in April 2009. Although white pines in the Southwest (Arizona and New Mexico) have been repeatedly surveyed for blister rust since its discovery in the Sacramento Mountains of southern New Mexico in 1990 (1,2), this was the first confirmation of C. ribicola in Arizona.
