Pre-emergence application of pendimethalin at 0.25 kg/ha either with atrazine or alachlor or metolachlor each at 0.5 kgha or metribuzin at 0.15 kg/ha gave significantly lower density of monocot and dicot weeds at all the intervals and also recorded higher grain yield of maize as compared to all other treatments. None of the herbicides applied alone or as mixture at tested rates had adverse effect on succeeding rabi oat arid mustard crops.
