Fumigation studies were conducted to determine the effects of air pollution on the host-pathogen relationship of Scotch pine and Scirrhia acicola. Scotch pine seedlings were inoculated with conidial isolates of S. acicola five days before or 30 min after fumigation with sulfur dioxide alone, ozone alone, or a combination of SO2 and ozone. After 8 wk, seedlings inoculated with S. acicola five days prior to fumigation exhibited more lesions than seedlings inoculated 30 treatment alone than after treatment with ozone alone caused. SO2 had less influence on stomatal closing than ozone had. (33 references, 2 tables)
