Abstract:

Direct seeded rice having weed diversity in a substantial amount and the use of single herbicide for weed management is ineffective to control the wide range of weed hence chances of weed flora shift and herbicide resistance in weeds is expected. So to study the efficacy of herbicide mixtures in wet direct seeded rice, an experiment was conducted at Institute Research Farm of ICAR-National Rice Research Institute, Cuttack (Odisha) during kharif season of 2017. The test rice variety was ‘CR Dhan 203’and the experiment was laid out in Randomized Block Design (RBD) with three replications and twelve treatments viz. nine herbicide mixtures (Azimsulfuron 50% DF+ Bispyribac sodium 10% SC @ (22+25) g ha-1 (T1), Flucetosulfuron 10% WDG (w/w) + Bispyribac sodium 10% SC @ (25+25) g ha-1 (T2), Penoxsulam 21.7% SC+ Cyhalofop-butyl 12% EC (w/v) @ (25+100) g ha-1 (T3), Fenoxaprop-p ethyl 6.7% EC (w/w) + Ethoxysulfuron 15% WDG (w/w) @ (50+15) g ha-1 (T4), Bispyribac sodium 10% SC + Ethoxysulfuron 15% WDG (w/w) @ (25+15) g ha-1 (T5), Cyhalofop-butyl 12% EC (w/v) + Ethoxysulfuron 15% WDG (w/w) @ (75+15) g ha-1 (T6), XR 848 (benzyl ester) 2.5% EC (w/v) + Cyhalofop-butyl 12% EC (w/v) @ (25+100) g ha-1 (T7), Flucetosulfuron 10% WDG (w/w) + Pretilachlor 30.7% EC @ (25+500) g ha-1 (T8), Bensulfuron methyl 0.7% + Pretilachlor 7% GR @ (70+700) g ha-1 (T9)), single herbicide Bispyribac sodium 10% SC @ 30 g ha-1 (T10), weed free (T11) and weedy check (T12). Result was found that among the weed management treatments, the weed free treatment (T11) registered significantly highest value and was at par with Fenoxaprop-p ethyl 6.7% EC (w/w) + Ethoxysulfuron 15% WDG (w/w) @ (50+15) g ha-1 (T4) regarding yield and yield attributes like effective tillers m-2 and panicle weight, number of grains panicle-1, number of filled grains panicle-1, grain and straw yield, whereas the effects of the treatment remained non-significant in test weight and harvest index.
