The experiment on weed control in rice bean was conducted at Hebbal, Bengaluru for three years 2012, 2013 and 2014 using pre- and post-emergent herbicides along with manual weeding. Results revealed that the weed free control treatment recorded the lower weed count (11.11/m2), weed dry matter (10.6 g/m2) with higher weed control efficiency (95.3%) and seed yield (1.42 t/ha). The higher B:C ratio of 2.62 was recorded with pre-emergence application of pendimethalin 1.0 kg/ha + one hand weeding at 5 weeks after sowing (WAS) followed by pre-emergence application of oxyflurofen 50 g/ha + one hand weeding at 5 WAS (2.61).
