The effect of isolates of Rhizoctonia, Phytophthora, and Pythium species on propagation of cuttings from 16 woody plant species was evaluated under intermittent mist in sand or peat-perlite during June, July, and August 1979. Symptoms ranged from severe basal stem rot and death to minor necrosis and root stunting. Rooting medium had little influence on symptom expression in most cases.
