Improving Conifer Seedling Quality with CONFER

CONFER(R), a potent plant growth regulator containing the active ingredient paclobutrazol, was evaluated as a replacement for dormancy inducing treatments for container grown conifer seedlings. CONFER provided effective short term control of stem height growth of European larch, white spruce and lodgepole pine while allowing stem and root growth. At rates of 1.0 to 2.5 kg a.i./1000 m 2, root growth of white spruce was stimulated both while in the container and after outplanting. Rates of 0.5 to 5.0 kg a.i./ 1000 m2 stimulated root growth of lodgepole pine seedlings both in the containers and after outplanting.
