Performance of Post-emergence Application of Bispyribac in Dry-seeded Rice

An experiment was conducted at University Seed Farm, Kapurthala during 2006 and 2007 to find out performance of few pre- and post-emergence herbicides in dry seeded rice. During 2006, pre-emergence application of pendimethalin 0.75 kg/ha followed by one hand weeding produced highest seed yield (4049 kg/ha) which was at par with post-emergence application of bispyribac (Nominee gold 10 SC) 30 g/ha (3554 kg/ha). During 2007, significantly higher yield was obtained with the integration of pre-emergence pendimethalin 0.75 kg/ha with post-emergence application of bispyribac 25 g/ha (5016 kg/ha).
