Management of wilt diseases of linseed (Linum usitatissimum L.) under in-vivo condition caused by Fusarium oxysporum f.sp. Lini

Abstract

A field experiment was conducted during rabi 2018-19 and 2019-2020 in alluvial soil at student research farm pili kothi, T.D.P.G. College, Jaunpur. To assess the plant disease incidence and response of different fungicides in controlling the disease and its effect on different yield contributing character. Nine treatments were taken constituting one check. The minimum PDI in 2018-19 was found in treatment treatment first (23.83). The maximum PDC in year 2018-19 was found in treatment first (62.15). In yield contributing character during 2018-19, the maximum plant population was found in treatment first and three (258.33), seed yield (kg./ha.) found maximum in treatment first (0.966), the maximum thousand grain weight (gm.) was found in treatment first (9.10), avoidable yield loss was found maximum in treatment first (55.27), the maximum benefit cost ratio was found in treatment first (0.88). In 2019-20 The minimum PDI were found in treatment treatment first (25.01). The maximum PDC treatment first (45.10). Yield contributing character maximum plant population was found in treatment first, three, four, six, (250), seed yield (kg./ha.) found maximum in treatment first (0.95), the maximum thousand grain weight (gm.) was found in treatment first (9.30), avoidable yield loss was found maximum in treatment first (59.12), the maximum benefit cost ratio was found in treatment first (0.88). During course of investigation following all the technical programme the result shows for manging the wilt disease in linseed one has to follow the seed treatment Thiram and Bavistin, which also enhances the yield.
