Abstract: Carnation (Dianthus caryophyllus L.) is one of the most important cut flowers in the world. It is one of the major export oriented crop grown in controlled conditions and it is the second most important flower grown in India. Fusarium wilt caused by Fusarium oxysporum f. sp. dianthi is one of the major constraints for carnation production causing a yield loss up to 40%. So a total of nine fungicides, six botanicals and two bioagents were screened in-vitro against Fusarium oxysporum f. sp dianthi causing wilt of carnation. Out of which systemic fungicides such as Carbendazim, Propiconazole, Difenconazole were found effective, but the contact fungicide such as Chlorothalonil and Mancozeb were found to be effective at higher concentrations. Among the bioagents Trichoderma harzianum (UAHS Shivamogga) isolate was found to be effective than other biogents.
