Screening of Three Pre-emergence Herbicides for Intensive Plantation Management In Michigan
Three herbicides were applied to newly planted seedlings of six species—European larch (Larix decidua Mill.), Kellogg hybrid pine (Pinus nigra Am. X. P. densiflora Sieb. and Zucc.), northern red oak (Quercus rubra L.), tag alder (Alnus B. Ehrh. spp.), black locust (Robinia pseudoacacia L.), and ailanthus (Ailanthus altissima (Mill) Swingle). Survival and growth and the effectiveness of weed control were assessed at the end of the first growing season. Simazine was the only general purpose herbicide tested that was nontoxic and effective for all species. Diphenamid was safe but ineffective, and hexazinone was effective but safe only at low levels for tag alder and Kellogg hybrid pine. Tree Planters' Notes 39(2):13-18; 1988.
