Host specificity of Phytophthora megasperma from Douglas fir, soybean, and alfalfa

Host specificity of Phytophthora megasperma from Douglas fir, soybean, and alfalfa

Phytopathology 71(1): 65-68

Pathogenicity of 28 isolates towards Douglas fir was tested by: (a) inoculating 8-month-old seedlings through cuts in the main stem and measuring the length of the resulting lesion after 42 days in a greenhouse; and (b) by planting 2-yr-old seedlings in infested soil, and scoring the root systems for discoloration after 8 wk. Of 19 isolates from Douglas fir 6 were pathogenic to both Douglas fir and soybean, causing extensive root rot and large lesions on tree seedlings.
