Abstract
The control of weeds in lucerne has always been one of the major factors limiting the acreage that could be established in anyone year and the total acreage that could be put under lucerne on a farm in Kenya. This was principally due to the fact that the lucerne had to be weeded by hand, and that it took anything from 60-100 woman days to clean an acre of seedling lucerne and another 30-50 woman days annually, to keep the established lucerne free of weeds. In addition, as the greatest quantity of weeds was to be found during the rainy season, when there is the greatest amount of work to be done on the farm, it can be appreciated, that unless a very large labour force was kept solely for that purpose, the acreage of lucerne that could be maintained was limited, in the writer's case to 120 acres, of which not more than 30 could be replanted or developed in anyone year. It was with this problem in mind that one of the larger companies dealing in herbicides was approached in 1954 in order to see whether any herbicide existed on the market that would make this task easier.
