With the progress of large scale farming in Ghana the use of herbicides is likely to replace labour as a means of weed control in crops. Simazine was tested against hand weeding and no weeding at 2 lb. and 4 lb. per acre and at different times of application. Pre-emergence application was more effective than post-emergence. 2 lb. or 4 lb. pre-emergence application of simazine was as effective as 'hand weeding' for weed control in maize in terms of crop yield. In terms of effective weed control, 4 lb. acre pre-emergence was better than 2 lb./acre preemergence application of simazine although this did not reflect in differences in grain yields of maize. Digitaria horizontalis proved to be the most difficult weed to control with simazine at the different levels.
