Practical lessons for northern Britain from a three-year feasibility study of cultivar resistance-based integrated control of potato blight (P. infestans)
The feasibility of matching blight fungicide inputs more closely to cultivar resistance to foliar blight was examined in three years (2009 to 2011) of field trials in Scotland. Separate evaluations of integrated control were made for rapid canopy development and the stable canopy phase of crop growth because these two growth phases normally present substantially different challenges from blight. It was clearly demonstrated that fungicide inputs to plots of more resistant varieties could be substantially reduced without compromising the control of leaf blight, even in the presence of the more aggressive genotype 13_A2 and under conditions more conducive to disease development than those prevailing in growers’ crops.
