Abstract:
Fungicides are the most common mean for the management of leaf spot of turmeric crop caused by Colletotrichum capsici (syd.) Buttler and Bisby. Four fungicides viz., Sixer (Mancozeb 63% W.P. + Carbendazim 12% W.P.), Ridomil gold (Mancozeb 64% w/w + Metalaxyl-M 4% w/w), Carzim 50 (Carbendazim 50% W.P.) and Captab 20% W.P. were screened at 0.2% dose against the pathogen by paper disc method. Amongst the fungicides, Carbendazim 50% @ 0.2 percent showed maximum zone of inhibition (2.43cm) of mycelial growth of the pathogen. Effect of Mancozeb 63%+Carbendazim 12% showed zone of inhibition of 1.53cm in inhibiting the mycelial growth of C. capsici and was found next to Carbendazim 50% per cent. Captab 20% (1.34 cm) also showed effective results as compared to mancozeb 64% + metalaxyl-M 4% (0.83 cm) in inhibition of mycelia growth of Colletotrichum leaf spot of Turmeric.
