Abstract

Linuron applications at 1 lb per acre severely injured only one of the nine ground cover species tested in this study (C. edule). Amino triazole at 1 lb per acre was applied to all species, except Ajuga repens or Delasperma alba, without severe injury. Injury from MCPP was less severe than 2,4-D in most instances and would appear to be safer in these tests at herbicidal rates. However, injury was apparent from MCPP on Ajuga repens, although 2,4-D amine did not appear to cause injury in this test. Bromoxynil appeared to have contact effects only (as indicated by early leaf burning) on Carpobrotus edule, Delasperma alba, Hypericum calycinum, and Vinca minor; however, regrowth was normal.
