Host survey and detection for thousand cankers disease pathogen, Geosmithia morbida, and Genetic Variability of Walnut Populations in Great Smoky Mountains National Park.

Description

"PI is surveying the walnut of the park to look for evidence of thousand canker disease. If he finds any trees with symptoms, he will collect material to use to study the genetics of the fungus that causes the disease. He is also studying the genetic diversity of the trees. Butternut also can catch this disease. Surveys in 2012 from Calderwood to Big Creek found 26 potentially symptomatic trees, 2 of which, in Cataloochee and Big Creek, were confirmed positive for 1,000 canker disease fungus. No beetles were collected in traps set out late in the season at Oconaluftee, Cataloochee, and Big Creek. Trees were found to be symptomatic at Foothills Parkway--Calderwood, Hazel Creek, and Cataloochee in 2013. Leaves of 50 trees were collected for future analysis of walnut genetic diversity. Funding ended in 2013."
