Weed management is a serious problem in oil palm cultivation and herbicides mixtures will be pertinent in the control of considerable broad spectrum of weeds in oil palm.  In view of this, a study was conducted in 2014 at the Nigerian Institute for Oil Palm Research (NIFOR), Benin City to evaluate the efficacy of tank mixture of glyphosate + metsulfuron on weed control in oil palm. Treatments which consisted of glyphosate + metsulfuron at 1.5 + 0.01 kg a.i. ha-1, glyphosate +metsulfuron at 1.0 + 0.01 kg a.i. ha-1, fluroxypyr at 0.8 kg a.i. ha-1,  fluroxypyr at   0.4 kg a.i. ha-1, glufosinate at 0.8 kg a.i. ha-1 , triclopyr at 0.36 kg a.i. ha-1, triclopyr at kg a.i. ha-1 and a weedy control plot were laid out in a complete randomized complete block design in three replicates.  The result showed that among thirty weed species recorded, six families were monocot. and fourteen families were dicot. Plot treated with tank mixtures of glyphosate+metsulfuron at 1.5 +0.01 kg a.i. ha-1 sustained weed control up to 12 weeks and reduced weed incidence by 61.67 %. Weed control efficiency was 88.5% and biomass of weed re-growth was 0.1 kg m-2 respectively. Fluroxypyr, glufosinate and triclopyr were less efficacious in control of broad spectrum of weed.  The study concluded that tank mixture of glyphosate plus metsulfuron, at 1.5 + 0.01 kg a.i. ha-1was sufficient in broad spectrum weeds control in young oil palm.
