Abstract:
The Field experiment entitled on Weed management in transplanted rice through Flucetosulfuron 10 % WG and its residual effect on succeeding green gram was conducted at College of Agriculture, Navile, Shivamogga, University of Agricultural and Horticultural Sciences, Shivamogga, during
kharif 2013 and 2014 and
rabi 2014-2015. Weed control treatments consisted of Flucetosulfuron 10 % WG at different doses (15 to 30 g a.i. ha
-1) and other herbicides Bispyribac Sodium 10 % SC 20 g a.i. ha
-1, Azimsulfuron 50 % DF 35 g a.i. ha
-1 and hand weeding. Dominant weed flora observed in the experimental plots among grasses were
Echinochloa sp. (
colonum &
crusgalli) and
Leptochloa chinensis among sedges
Cyperus difformis and
Cyperus iria whereas in case of broadleaf weeds (BLW)
Ludwigia parviflora,
Eclipta prostrata,
Alternanthera sessilis,
Fimbristylis miliacea and
Marselia quadrifolia. Application of Flucetosulfuron 10% WG @ 25g a.i. ha
-1 gave consistently good control of all category of weeds,
i.e., grasses, sedges and broadleaf weeds and was on par with 10 % WG @ 30 g a.i. ha
-1 dose and these herbicides did not cause any phytotoxicity in preceding rice crop as well as succeeding crop green gram and recorded significantly higher grain yield in transplanted rice.
