Abstract

Wilt caused by Fusarium oxysporum Schlecht. is one of the devastating diseases in FCV tobacco of Karnataka. Two aggressive isolates (2 Fo and-l Fo) were taken for the study. The screening was carried out through poisoned food technique using potato sucrose agar (PSA),each at 0.1, 0.2, 0.3 and 0.4% concentrations. Antifungal activity was found in terms of percent inhibition. The results showed that Carbendazim, Thiophenate methyl, Dithane M-45, Score and Tilt inhibited mycelial growth of both the isolates upto 100% followed by Kocide- 27.7, 16.6%; Calixin - 33.3, 33.3%; Ridomil - 41.5,53.77% and Bayleton - 83.3, 77.7% respectively. The results demonstrated the efficacy of certain fungicides in controlling F. oxysporum in vitro.
