Can SpeedZone Southern Herbicide be tank mixed with Image Herbicide to kill crabgrass?


Tank mixing is not recommended unless your experience indicates that the tank mxture will not result in turf injury. When tank mixing certain herbicides with other selective herbicides, surfactants, etc, this can reduce the selectivity of the herbicide resulting in injurying or killing the grass. We recommend doing a small compatibility test in a glass jar to ensure the two herbicides mix properly and then do a small test application in the lawn to determine sensitivity. Do not broadcast over the lawn without doing a test application first.
