I plan to use SpeedZone for spot treatment of Ground Ivy. Addition of a non-ionic surfactant is typically recommended for liquid herbicide application to broadleaf weeds. I do not see this recommendation on the label, nor do I recognize a surfactant on the ingredient list.
SpeedZone Lawn Weed Killer Concentrate does contain a surfactant and additional one is not required for use with it. The SpeedZone Red which is very similar to the Lawn Weed Killer does state on the product label that adding one may reduce the selectivity on the turfgrass so it could harm your lawn in adding one.
