Abstract

Glyphosate [N-(phosphonomethyl)glycine] applied to cranberry (Vaccinium macrocarpon Ait.) as a spray at 4 kg/ha in March controlled aster (Aster subspicatus Nees) 77 to 87%. Glyphosate swab treatment with 6% solution in July or August, 1978 controlled spirea (Spiraea douglasii C.) 90%. A single application of terbacil (3-tert-butyl-5-chloro-6-methyluracil) in April, 1976 at 2 kg/ha controlled inflated rush (Carex vesicaria L.) 70% for 3 yr. Phytotoxicity was not observed on ‘McFarlin’ cranberry vines from any of these glyphosate or terbacil applications. Phytotoxicity did result from April, July, or August spray applications of glyphosate. Swab treatments did not cause any injury to cranberry.
