Integrated management of vascular wilt of lentil caused by Fusarium oxysporum f. sp. Lentis

Abstract

An extensive study was undertaken to manage the most vigorous, polyphagous pathogen Fusarium oxysporum causing wilt disease in lentil. A field experiment was conducted during 2017-18 cropping season to evaluate different management options (seed treatment with thirum, Trichoderma harzianum and soil drenching alone with propiconazole and in combination with organic manures) on wilt of lentil caused by Fusarium oxysporum f. sp. Lentis under artificial inoculation condition in pots and field. It was observed that the minimum 2.56% disease incidence was recorded in soil application of Propiconazole @ 500 ml/ha 15 DAS as compared to control (66.66%) in pot condition. At field level the lowest percent disease incidence (5.05%) was recorded in soil application of Propiconazole (@ 500 ml/ha after 15 DAS, whereas 7.07 percent disease incidence was observed in soil application of Neem cake @0.1 kg m-2 + Tricoderma harzianum @1 g m -2 and soil Application of Tricoderma harzianum @1 g m -2 + Press mud @ 2.5 kg m-2 compared to control (14.14%) in field condition.
