Evaluation of Alkombo and tank mixture of Almix+butachlor for the control of weeds in transplanted rice

摘要

A field experiment was conducted at CCS Haryana Agricultural University Regional Research Station, Karnal during kharif 2000 and 2001 to evaluate the efficacy of Alkombo [Almix (chlorimuron ethyl+metsulfuron methyl)+anilofos] (readymix) and tank mixture of Almix+bulachlor in transplanted rice. Alkombo at 280.5 g ha~(-1) was at par with butachlor at 1500 g ha~(-1), anilofos at 400 g ha~(-1) and pretilachlor at 1000 g ha~(-1) in reducing the dry weight of weeds and these treatments proved significantly superior to butachlor at 1250 g ha~(-1), pretilachlor at 625 g ha~(-1) and anilofos at 300 g ha~(-1). Butachlor and Almix as tank mixture did not significantly decrease the dry weight of weeds over the alone application of butachlor at corresponding dose. Application of Alkombo at 280.5 g ha~(-1), butachlor at 1500 g ha~(-1), anilofos at 400 g ha~(-1) and pretilachlor at 1000 g ha~(-1), and tank mixture of Almix+butachlor at 4+1250 g ha~(-1) produced similar effective tillers and consequently grain yield of rice to that of plot kept weed free for the whole season.
