Direct seeded rice, Fenoxaprop-p-ethyl, Weed control
The trial was conducted for two years during November–February 2006 and during December–April 2007. The treatments included fenoxaprop-p-ethyl at 47.44, 51.75, 56.06, 60.38 g/ha, cyhalofop-butyl 62.5 g/ha, Echinochloa spp. were the major weed comprising about 75% of the weed population. Echinochloa crusgalli and Echinochloa stagnina were present almost in equal proportions. Fenoxaprop-p-ethyl at all the tested doses was effective in controlling Echinochloa spp. Fenoxaprop sprayed 60.38 g/ha recorded yields on par with hand weeding and standard check cyhalofop. This dose can be recommended in situations where Echinochloa spp. is a major problem.
