Abstract:
An experiment was conducted at Agricultural Research Station, Ummedganj, Kota, during kharif 2020 to investigate the bio-efficacy evaluation of new generation post emergence herbicides on urdbean. The result revealed that among herbicides the maximum and significantly higher growth characters, yield attributes and yield of urdbean was recorded with the application of Fomesafen 11.1% @ 220 g/ha + Fluazifop-p-butyl 11.1% @ 220 g/ha followed by Propaquizafop 2.5% @ 33.3 g/ha + Imazethapyr 3.75% ME @ 50 g/ha and Acifluorfen-sodium 16.5% EC @ 140 g/ha + Clodinafop-propargyl 8% EC @ 70 g/ha over rest of herbicidal treatments. Similarly, minimum weed density, weed dry matter and weed control efficiency was also recorded under application of Fomesafen 11.1% @ 220 g/ha + Fluazifop-p-butyl 11.1% @ 220 g/ha closely followed by Propaquizafop 2.5% @ 33.3 g/ha + Imazethapyr 3.75% ME @ 50 g/ha, Acifluorfen-sodium 16.5% EC @ 140 g/ha + Clodinafop-propargyl 8% EC @ 70 g/ha.
