A field experiment was conducted during the rainy season, 2015 at Hyderabad, Telangana, on sandy-loam soil, to study the bio-efficacy of new-generation herbicidal combinations for weed management and their impact on weed flora, yield and economics of greengram [Vigna radiata (L.) Hepper]. A medium-duration variety ‘MGG 295’ was used for the study. The results revealed that combinations of haloxyfop-p-methyl @ 135 g/ha + imazethapyr @ 75 g/ha at 12–15 days after sowing (DAS) and quizalofop ethyl @ 50 g/ha + imazethapyr @ 75 g/ha at 12–15 DAS as early post-emergence were found promising for Southern Zone of Telangana for getting higher productivity and profitability.
