Abstract
Abstract ‘Bartlett’ pear trees were sprayed 2 weeks after full bloom or 4 weeks before harvest with a single application of succinic acid 2,2-dimethylhydrazide (Alar) at 1,000 or 2,000 ppm. Some trees that received 1,000 ppm were given a second application of Alar at 1,000 ppm 3 weeks after full bloom or 3 weeks before harvest. Alar was as effective as NAA at 10 ppm in preventing preharvest drop of fruits. Alar applied as a double spray early in the season or as a single or double spray late in the season was equally effective. Use of Alar as a preharvest drop spray provides great flexibility as it can be applied over a wide range of time. No undesirable side effects were noted from the use of Alar.
