ABSTRACT

A field experiment was conducted during rabi season of 2011-2012 at College of Agriculture, Vellayani, Kerala, India to evaluate three promising new generation herbicides for managing water cabbage. The experiment was laid out in randomized block design with eight treatments replicated thrice. The treatments comprised of Azimsulfuron @ 20 and 30 g/ha, bispyribac-sodium @ 20 and 30 g/ ha, (metsulfuron-methyl + chlorimuron-ethyl) @ 4 and 6 g/ha, 2-4 –D @ 1 kg/ha and a weedy check. The results of the field study on weed control efficiency of the different herbicides indicated that 2, 4-D @1 kg a.i. ha-1 was most effective for controlling water cabbage. Among the new generation herbicides (metsulfuron methyl + chlorimuron ethyl) @ 6 g a.i. ha-1 and bispyribac sodium @ 30 g a.i. ha-1 were equally effective for controlling water cabbage.  Azimsulfuron at both doses were found to be least effective in controlling water cabbage.
