Abstract:

A field experiment was conducted at the research farm of RVSKVV Gwalior during Rabi 2018-19 and 2019-20 to assess the efficacy of different pre- and post- emergence herbicides to manage Cuscuta campestris Yunck.  in berseem. C. campestris, well known as a dodder, is a serious problem in berseem. Eight treatments consisting of pre-emergence application (PE) of pendimethalin 1000 g/ha, early post-emergence application (EPoE) at 10 days after sowing (DAS) of pendimethalin 1000 g/ha, oxyfluorfen 250 g/ha PE, post-emergence application (PoE) of imazethapyr 40 g/ha after first cut at 60 DAS, imazethapyr 40 g/ha PoE after last cut at 120 DAS, imazethapyr 40 g/ha PoE after first cut + 40 g/ha after last cut, Cuscuta free and control plot (no herbicide application) were laid out in RBD with three replications. Imazethapyr 40 g/ha PoE after first cut at 60 DAS was found to be very effective in controlling the C. campestris resulting 43% and 16% higher fodder and seed yield, respectively with 43.6% higher profitability. The next best was imazethapyr 40 g/ha PoE after first cut + 40 g/ha after last cut.  Pendimethalin PE and oxyfluorfen PE caused phytotoxicity to berseem due to the higher dose of both herbicides and reduced the fodder and seed yield drastically.
