Abstract

In studies of the effect of root temperature on the toxicity of 2,4-dichlorophenoxyacetic acid (2,4-D) to rubber rabbitbrush (Chrysothamnus nauseosus (Pall.) Britton), 75 F resulted in the highest mortality following 2,4-D treatment. Root temperatures had no effect on leaf cuticle thickness. In similar studies with Canada thistle (Cirsium arvense (L) Scop.) and Russian knapweed (Centaurea repens L.), little injury resulted from 2,4-D treatment at 45 F whereas at 90 F in Canada thistle and at 60, 75, and 90 F in Russian knapweed, severe injury and/or death resulted.
