Management of Pigeonpea Wilt Caused by Fusarium udum Butler through Integrated Approaches
Integrated Disease Management (IDM) approach was carried out to combat pigeonpea wilt with a combination of fungicides, bio agents, organic amendments and different cropping systems in kharif seasons of four years viz., 2006, 2007, 2008 and 2009. Based on the performance, four treatments were identified as best practices for the management of pigeonpea wilt viz., carbendazim seed treatment @ 2 g/kg of seeds + Trichoderma viride @ 2.5 kg/ha in FYM @ 50 kg / ha recorded lowest mean wilt incidence of 11.38 per cent with highest mean yield of 969.18 kg/ha, followed by carbendazim seed treatment @ 2g/Kg of seeds + ZnSo4 @ 25 kg/ha which recorded mean wilt incidence of 11.75 per cent with mean yield 951.25 kg/ha. However, Trichoderma viride seed treatment @ 5g/kg of seeds + Trichoderma viride @ 2.5 kg/ha in FYM @ 50 kg/ha which recorded mean wilt incidence of 11.97 per cent and yield of 929.63 kg/ha and pigeonpea intercrop with sorghum @ 1:1 recorded mean wilt incidence of 17.62 per cent and yield of 632.18 kg/ha were also found effective in controlling wilt incidence and increasing yield compared to untreated control which recorded highest wilt incidence of 53.04 per cent and lowest yield (314.95 kg/ha).
