OSTI ID:5011204
Variability, ranging from complete resistance to extensive susceptibility, was observed when flowers and bracts of 14 cultivars of poinsettia were inoculated with spores of Botrytis cinerea. Flowers and bracts were not visibly injured by exposure to ozone levels up to 45 pphm. Ozone did not have significant fungicidal effects, as measured by visual disease incidence following incubation, when inoculated flowers and bracts were exposed to ozone at 15, 25, 35, and 45 pphm ozone for 4 hr prior to incubation. 8 references, 1 table.
