Abstract
From May 1977 to November 1977 a herbicide trial was carried out at Coffee Rsearch Station Ruiru.Kenya to evaluate the performance of three contract herbicides and two soil acting herbicides. WL 63611 20% EC used as a contact herbicide proved to be effective and the most persistent. WL 63611 40% SC although effective was not as persistent as the first one. Of the soil-acting herbicides, only EL 171 50% showed any signs warranting future consideration at the rates treid. Devrinol if tried in future should be applied at a higher dosage than originally tested. Dirimal should not undergo any further trial. The practical implications of this trial has been discussed.
