Screening of fungicides against leaf spot of turmeric caused by Colletotrichum capsici
Nabakishor Nongmaithem and Thiyam Rebika
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.
