Diversity Among Isolates Of Phytophthora Cinnamomi From Ornamental Plants In South Carolina, Simon Schreier
All Theses
Phytophthora cinnamomi is a devastating pathogen that can attack over 900 hosts. It is the most common species of Phytophthora isolated from woody ornamental crops in South Carolina but little is known about variability among isolates of P. cinnamomi that attack these plants. Therefore, 142 isolates of P. cinnamomi recovered from diseased plant samples submitted to the Clemson University Plant Problem Clinic between 1995 and 2011 were characterized for mycelium growth habit, growth rate, mefenoxam sensitivity, mating type, and sporangium morphology. Mycelium growth habit on PARPH-V8 selective medium was classified as aerial, appressed, or dwarf; 87% of isolates had the …
