Binadhan-14). The experiment was consisted of 20 treatments such as Control (T1), Hand weeding (T2), Bensulfuran methyl 8% +Acetachlor 14% (T3) , 2-4, D Amine 72SCL (T4), Pretilachlor 500EC (T5), Bispyriback sodium 300WP (T6), Pyrazosulfuran ethyl 10WP (T7), Trisulfuron 40WP (T8), Pendimethyline 33EC (T9), Metsulfuran methyl 20WDG (T10), Butachlor 5G (T11), Ethoxysulfuron 150WG (T12), Carfentrazol ethyl 24EC (T13), Fenoxpro-p-ethyl 9EC (T14), Glyphosate 480SL (T15), Paraquate dichloride 27.6% (T16), Bensulfuran methyl 120 gm+ Bispyriback sodium 180, 300WP (T17), Triafemon 240SC (T18), Penoxsulum 240SC (T19), Pyrazosulfuran ethyl 100gm+ Pretilachlor 100gm 20WP (T20). The experiment was laid out in a randomized completely block design with three replications. Fourteen weed species belonging to six families infested the experimental plots. The lowest weed density (3.00), weed dry weight (4.80) and the highest weed control efficiency (86.60) were recorded from treatment Ethoxysulfuron 150WG (T12). From the findings of the study, it can be concluded that herbicide Ethoxysulfuron 150WG followed by Bispyriback-sodium 300WP, Hand weeding and Pyrazosulfuran ethyl 10WP would be the most effective weed management practice for late transplanting boro rice (cv. Binadhan-14). | | Keywords : | | | Investigating, Effectiveness, Herbicides, Weed Suppression, Late boro rice, Binadhan-14 |
