Conclusion Apogee consistently regulated shoot growth of d���Anjou and Starkrimson pear trees, without accompanying negative effects on fruit size, yield, or return bloom as observed in other cultivars. In fact, strong vegetative growth control was accompanied by improved fruit set in d���Anjou. Root pruning achieved the year-one goal of reducing d���Anjou vigor and controlling tree size; the improved light penetration as a result of reduced vigor needs to result in stronger bloom and/or higher fruit set in 2013 in order for root pruning to be a viable management option.

Thanks to Herbie Annala for fabricating the root pruner; Gorham Blaine for supplying d���Anjou orchard sites, root pruning and harvest crew; and, Northwest Pear Bureau for funding. The d���Anjou pear tree on the left received no Apogee during the growing season. The d���Anjou tree on the right was treated with Apogee during the growing season. Photos were taken prior to harvest in September 2012. ���Savings in hand thinning time and/or increases in fruit sizes resulted in a net positive impact of $123/ha to $1368/ha compared with hand thinning alone.��� - Baugher, Schupp, et al.
