Can SpeedZone Lawn Weed Killer b tank mixed with Drive XLR8 to treat for clover and crabgrass?


Since SpeedZone Lawn Weed Killer Concentrate already contains a small percentage of surfactant and an additional surfactant is not advised on the product label and Drive XLR8 DOES require the use of a Methylated Seed Oil Surfactant for best results to treat crabgrass, we would not advise to tank mix these together for one application unless you test a small area of the lawn first.  If adding a surfactant to SpeedZone Lawn Weed Killer, you could possibly temorarily or permanently damage your lawn. We would recommend doing a small test spot application to the lawn to see if your turfgrass would be tolerant to using both in one application.
