Evaluation of multiple sources of resistance and integrated management of linseed wilt

Abstract

For screening under natural epiphytotics, a set of 90 initial varieties and advanced varieties from breeding trial were screened against wilt, alternaria blight, powdery mildew and rust under natural condition. Among them 11 entries viz., RL-29210, RLC-153 and BAU-15-06, test entries RC-1007, RLC-153, RLC-157, SLS-101, SLS-106, NDL-2014-11 and BAU-06-03 recorded multiple disease resistant reaction. An integrated disease management trial resulted that minimum disease incidence of wilt (20.92 %) and maximum grain yield (726.39kg/h)was recorded on ST with T.viride@ 4g/kg+ soil appln of T.viride @4g/kg with 40 kg/ha well rotten FYM which was at par with ST with T.harzianum @ 4g/kg + soil appln of T.harzianum @4g/kg with 40 kg/ha well rotten FYM recorded (26.67 %) disease incidence and (681.94kg/h) grain yield as compare to (56.67 %) wilt incidence and (501.39 kg/h) grain yield in untreated control.
