Impact of integrated weed management on weed flora distribution and weed dynamics in rice (Oryza sativa L.) under system of rice intensification (SRI)

Abstract

C.G.) during Kharif season of 2009 in Randomized Block Design (RBD) with three replications. The dominated weed flora of the rice field comprised Alternanthera triandra, Echinocloacolona, Fimbristylis miliacea and Cyperus iria throughout the crop season. Other weeds were Ischaemum rugosum, Boreriasirida, Commelina benghalensis, Cyanotis axillaris, Aeschynomene indica etc. observed in the experiment field. Results revealed that post-emergence combined application of Fenoxaprop-p-ethyl 60 g ha -1 + Ethoxysulfuron 15 g ha -1 at 20 and 35 DAT was statistically at par with hand weeding (twice) at 20 and 40 DAT for controlling weeds effectively in system of rice intensification method of rice.
