Abstract
Eight fungicides including prochloraz, tebuconazole, benomyl, mancozeb, thiophanate-methyl, azoxystrobin, and fluazinam were examined for their control effects on Fusarium bulb and root rot of oriental orchid, Cymbidium goeringii. Among the chemicals, prochloraz and tebuconazole were the most effective on suppression of the causal pathogen, F. oxysporum in vitro and on control of the disease in vivo. Prochloraz and tebuconazole inhibited mycelial growth of the fungi 95~100% at 10ppm a.i. and microconidial germination 75~100% at 100ppm a.i. Prochloraz and tebuconazole showed 80~92% and 84~88% protective control value on the disease, respectively. However, curative effects on infected orchid were relatively low. Other chemicals showed no or lower than 20% curative and 50% protective control value. Results indicated that prochloraz and tebuconazole can be used for the control of the Fusarium bulb and root rot of oriental orchids. However, the chemicals need to be applied prior to the disease development to achieve successful control efficacy.
