To study the efficacy of neem cake, soil drenching of metalaxyl, post-emergence application of glyphosate at very low concentrations alone and in combination with 1% solution of (NH4)2SO4 and 125% of recommended fertility, field experiments were conducted at the villages Ganghala and Bidhwan in Bhiwani district of Haryana during Rabi seasons of 2014-15 and 2015-16, respectively. Feasibility of adoption of results of studies conducted earlier on use of glyphosate 25 g/ha at 30 DAS and 50 g/ha at 55 DAS is being demonstrated by multi location field trials through farmers participatory approach in different parts of state during 2010-2016. Neem cake 400 kg/ha at sowing fb soil drenching of metalaxyl MZ 0.2% at 25 DAS fb glyphosate at 40 g/ha at 45 DAS or neem cake 400 kg/ha fb pendimethalin (PPI) at 0.75 kg/ha fb metalaxyl 0.2% at 25 DAS did not prove effective in minimizing density of Orobanche.

Post-emergence application of glyphosate at 25 and 50 g/ha with 1% solution of (NH4)2SO4 at 30 and 55 DAS showed promise with 85- 91% control of this weed not only in experimental fields but in large scale demonstrations on farmers’ fields.
