Abstract: A field experiment was conducted during the Kharif 2017 at S.G. College of Agriculture and Research Station, Jagdalpur on sandy loam soil with five treatments viz., water imponding of 15, 30 and 45 days 10 days after transplanting, bispyribac sodium 25 g ha^-1 as post-emergence and without water imponding (Control) in factorial randomized block design with four replications. The data on weed control efficiency at 60 DAT were more important and noticed significant change in weed control efficiency regardless grassy, sedges and broad leaved weed due to imponding water and herbicide application. The maximum weed control efficiency was recorded under 30 days water imponding 10 days after transplanting (64.93, 81.25, 93.96, 72.07, 94.23, 75.28, 63.54, 62.66 and 82.09% for Panicum repens, Brachiaris reptans, Cyperus difformis, Eleocharis indica, Fimbristylis miliacea, Dopatrium junceum, Ammania baccifera, Rotala indica and other, respectively).
