Abstract
In conjunction with a brief historical study of probable timing and critical environmental factors associated with winter injury of apple trees in New Brunswick, we evaluated the effects of Alar-85® and Dupont surfactant WK® on seasonal changes in cold hardiness and dormancy intensity of Spur Mac/M.111. An examination of historical winter injury patterns in New Brunswick revealed that there was, on average, a severe occurrence once every 6 yr. These events appeared to be associated with late winter/early spring shoot damage when the shoots are non-dormant and deacclimating. Alar-85® and Dupont surfactant WK® reduced freezing injury although these effects were not consistent from year to year.Key words: Malus × domestica, apple, cold hardiness, Alar-85®, surfactant WK®
