The antitranspirants, XEF-4-3561-A. Wilt Pruf, Plantgard, Folicote, Clear Spray, and Vapor Gard, were sprayed on container-grown lodgepole pine, white spruce, western hemlock, and Douglas-fir seedlings before or after a 12-week cold (+ 2 °C) storage period. The effects of the six antitranspirants on root growth capacity, storability, and field performance varied between species. XEF-4-3561-A. Wilt Pruf, Folicote, and Vapor Gard increased moisture stress avoidance of all species, while Plantgard and Clear Spray had no effect. None of the six antitranspirants are recommended for use on white spruce, western hemlock, or Douglas-fir planting stock because of the risk of reducing field performance. Further trials of XEF-4-3561-A and Wilt Pruf on lodgepolo pine seedlings seem War-ranted.
