An experiment was undertaken at Gezira Research Station Farm during season 2006/07 to evaluate the efficacy and selectivity of Mayor 24EC, Goalan 24EC (new formulations of oxyfluorfen) Depend 50EC and Clean-up 33EC (new formulations of pendimethalin) 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 to good effects on broad-leaved weeds. Herbicides treatments reduced the man-hours required for supplementary weeding by more than 77%. They also reduced weed biomass at harvest in comparison with the unweeded control. Unrestricted weed growth reduced onion bulb yield by about 68%. Herbicides treatments significantly increased onion bulb yield in comparison with the unweeded control. Supportive hand-weeding to the herbicides treatments resulted in further increase of weed control and onion bulb yield in comparison with the respective treatment without supportive hand-weeding and gave yield comparable to that of the weeded control
