Experiments on roguing virus‐diseased plants from plots of Majestic potatoes, which have been in progress since 1943, were continued in 1946. Plots were rogued in mid‐June, early and late July, and plants were lifted from these plots at the end of July, August and September respectively. Roguing had little effect in reducing the spread of rugose mosaic (caused by potato virus Y ). The spread of leaf roll was reduced to half that on unrogued plots by roguing on 14 June. Later roguing did not reduce the spread of leaf roll, unless combined with early lifting. Early lifting increased the effect of early roguing. In spite of these results roguing main crop potatoes in the south of England is not considered a practical control measure.
