Abstract
Fentrazamide and flufenacet were evaluated for weed control in transplanted rice during kharif seasons of 2002 and 2003. Echinochloa crus-galli was the dominant weed. Season long weed competition caused 56.3% paddy yield reduction compared to weed free check. Fentrazamide at 105–120 g/ha, flufenacet 120 g/ha, butachlor 1500 g/ha, pretilachlor 625 g/ha and anilofos 400 g/ha provided effective control of E. crus-galli and yields due to these treatments were significantly higher than unweeded control but at par with weed free control. Flufenacet was quite effective in controlling weeds at 120 g/ha, whereas higher dose of 150 g/ha was toxic to crop. The magnitude of toxicity varied depending on the type of rice grown.The toxicity was higher in fine rice (Taroari Basmati and Sugandha) compared to coarse rice (IR-64).
