Abstract
Investigations were carried out for two seasons (July 1998 November 1998 and June 1999 October 1999) at FIPPAT Agricultural experimental farm, Padappai, to study the efficiency of three pre-emergence herbicides applied under different tillage systems viz. conventional tillage, conservation tillage and tillage fallow (no-till), for controlling the mixed population of weeds in wet-seeded rice. The herbicides viz. Pretilachlor 750 g ha, Butachlor 1250 g ha and Oxadiargyl 100 g ha were applied at 4 DAS, compared with hand weeding (twice) and unweeded control. Results revealed that, Oxadiargyl and Pretilachlor application effectively controlled the weeds in both the season. Among different tillage systems, conservation tillage was found effective. Hence, Oxadiargyl 100 g ha and Pretilachlor 750 g ha applied at 4 DAS under conservation tillage system compared with other tillage systems may therefore be recommended for effective weed control in wet-seeded rice.
