Bioefficacy of Diclosulam in soybean

A farmer’s participatory field experiment was conducted during two consecutive kharif seasons of 2019–20 and 2020-21 at farmer’s fields in Bichhia village of Sehore district of Madhya Pradesh to assess the effect of pre emergence herbicide diclosulam on weeds and growth and yield of soybean. The application of preemergence diclosulam@26 g/ha gave 22.95 per cent higher seed yield as compared to farmer’s practice. Further, application of pre-emergence diclosulam @ 26 g /ha treatment gave significantly higher pods per plant, plant height and straw yield of soybean and significantly reduced the weed count and weed dry matter as compared to all other treatments tested.
