摘要

A field experiment was carried out at G.B.P.U.A. & T., Pantnagar during 1996-97 and 1997-98 to study the management of Ipomoa spp. and other weeds in spring planted sugarcane. Significantly lower density of Ipomoea spp. was recorded with atrazine at2000 g ha~(-1) applied just after hoeing, metsulfuron methyl at 4 and 6 g ha~(-1) and chlorimuronethyl at 10 g ha~(-1) applied as post-emergence as compared to weedy. The highest cane yield was recorded in weed-free plot. Among the herbicide treatments,atrazine at 2000 g ha~(-1) applied just after hoeing provided effective control of weeds, recorded the lowest weed dry matter and gave at par cane yield with pre-emergence application of metribuzin at 1000 g ha~(-1) and diuron at 1000 g ha~(-1) applied just after hoeing.
