Effect of low-level ozone fumigations on crown rust of oats
Journal Article
·
· Phytopathology; (United States)
Exposure of crown rust differential varieties of Avena spp. to 10 pphm ozone for 6 hr in the light for 10 days after infection with Puccinia coronata significantly reduced the growth of uredia. Urediospores produced on the plants exposed to ozone germinated as well, produced as many appressoria, and resulted in as much infection as spores produced on unexposed leaves. Exposure on dry leaves to 20 pphm ozone for 3 hr for 1-5 days did not affect urediospore germination, appressoria formation, or penetration. 9 references, 1 figure, 3 tables.
