Effect of Herbicides on Weeds in Transplanted Rice
Abstract
Effect of herbicides on weeds in transplanted rice was evaluated in a field experiment conducted during kharif seasons of 1999 and 2000. Echinochloa colona, Caesulia axillaris, Cyperus iria, Commelina benghalensis and Fimbristylis milliaceae were the major weeds in the experimental plots. Riceguard and combination of anilofos and triclopyr at all the doses provided effective control of E. colona, C. iria, C. axillaris, F. milliaceae and C. benghalensis. All the weed control measures produced significantly higher rice grain yield than weedy check. The highest grain yield of rice was obtained with the application of riceguard at 390 g a. i. ha−1 and anilofos+triclopyr (375+521.5 g a. i. ha−1). Pretilachlor and triclopyr at any of the doses could not yield at par with riceguard and anilofos+triclopyr.
