Abstract

This report evaluates a method used to determine the uniformity of spray coverage in a pear fireblight control experiment in 1972. Trees used for the experiment were mature 14-year-olds in a hedgerow planting at 11 hy 22 ft spacing. The trees were uniform in size, vigorous in growth (many 5-ft shoots per season) and completely grown together in the hedge. Standard vase-shaped pruning was practiced, giving a diameter of approximately 14 ft, with a height of 15 ft after dormant pruning.
