It does a good job on nutsedge in addition to the broadleaf weeds. Addition of a crop oil concentrate improves weed control. Basagran works primarily by contact action, so spray coverage is important. This chemical can burn foliage, so use directed sprays around ornamentals. Injury occurs more frequently in hot and humid weather.
Conifers are more susceptible to injury than other plants.
While most plants should be shielded from the spray, Basagran may be sprayed over the top of English ivy, pachysandra, and liriope. Image also controls nutsedge in the landscape as well as wild onion, but has a limited ornamental label. Image has some preemergence in addition to postemergence activity. The last group of herbicides are the selective grass herbicides. Unlike the broadleaf herbicides, these may be applied safely over the tops of many ornamental plants.
