| Description |
Panicles of Pennisetum americanum inoculated with Tolyposporium penicillariae maintained at a high RH (>95%) when exposed to post-inoculation temp. of 30°C for 3.5 h/day (range 15-32°) were not infected; those exposed to 30° for 7.7 h day-1 (range 20-38°) developed 30% infected florets; and those exposed to 30° for 5.4 h/day (range 26-33°) had 76% smutted florets. Of the temp. tested, min. temp. inhibited smut infection more than max. temp. With decreasing post-inoculation exposure time from 6.7 to O h/day at 50%). These results indicate that high RH periods of 168-192 h and a daily mean air temp. of c. 30° (range 25-35°) may be most favourable for smut infection, and that air temp.
