Title : Chemical and Biological Control Measures against Cumin Wilt Incited by Fusarium oxysporum f. sp. cumini

Abstract :

Wilt of cumin incited by Fusarium oxysporum f. sp. cumini is one of the important disease and a big constraint in successful cultivation. An investigation was made to minimize this disease by use of systemic and non systemic fungicides. All the fungicides significantly inhibited the mycelial growth of Fusarium oxysporum f. sp. cumini as compared to check at 100, 200, 500 ppm concentration. Carbendazim was found significantly superior at 200 and 500 ppm with maximum inhibition of mycelial growth followed by carbendazim+mancozeb. As the concentration of fungicides increased, the inhibition of mycelial growth was also increased and maximum inhibition was observed at 500 ppm concentration. Hexaconazole was least effective. All the fungicides tested as seed dresser, reduced wilt incidence of cumin in both the years and carbendazim was found significantly superior with minimum disease and maximum yield over control followed by carbendazim+mancozeb. Pooled analysis of two years data revealed that the maximum disease control (72.24%) was recorded in the treatment soil application of FYM + seed treatment with Trichoderma with maximum per cent yield increase (218.34) followed by soil application of Neem cake + seed treatment with Trichoderma with (64.33%) disease control and (202.05%) yield increase. The control resulted maximum incidence of wilt (61.06%) with lowest yield (99.25kg/ha) as compared to all other treatments.
