: An experiment was undertaken at Gezira Research Station Farm during season 2007/08 to evaluate the efficacy and selectivity of Prowl aqua 455 CS, Pendico 50EC (new formulations of pendimethalin) and Akofen 24EC (a new formulation of oxyfluorfen) on weed control in transplanted onion. Both pendimethalin and oxyfluorfen formulations excellently controlled grasses early in the season with long persistent effects. The tested products displayed moderate effects on broad-leaved weeds early in the season. The herbicides treatments reduced man-hours required for supplementary hand-weeding by 90%. They also reduced weed biomass at harvest in comparison with the unweeded control. Unrestricted weed growth reduced onion bulb yield by about 74%. The herbicides treatments significantly increased onion bulb yield in comparison with the unweeded control. Supportive hand-weeding to the herbicides treatments resulted in better weed control and onion bulb yield in comparison with the respective treatment without supportive hand-weeding. The bulb onion yield of each of the tested herbicides treatments, Prowl aqua, Pendico and Akofen, was comparable to that of its counterpart
