Summary. Trials in 1959, 1960 and 1961 failed to show significant differences in yield between potatoes (Solanum tuberosum L.) of three varieties receiving from seven to nine separate tractnr cultivations and similar potatoes in which the weeds were well controlled by pre‐emergence applications of a mixture of dinoseb(6.0 lb/ac)*and dalapon (2.5‐5.0 lb/ac), With less effective herbicide treatments. including simazinc and 2,4‐DES, there were significant reductions in yield. Preliminary taint tests in 1959 on cooked tubers suggested that slight tainting might have been caused by one of the treatments, but tests on potato crisps made from the 1959 and 1960 crops were completely inconclusive. Tubers from all the treatments in the 1959 and 1960 trials sprouted normally in the spring after harvest. Le désherbage des pommes de terre par des herbicides de pré‐émergence
