Barry from Jefferson La writes,
My lawn is Zoysia and want to kill crabgrass and St Augustine that invade it.
The lawn is 50 ft x 50 ft. Looking at Quinkill Max crabgrass & weed killer to solve the problem. Do you recommend and if so do I need a surfactant and can I apply it with the Chapin #6005 Sprayer?
Yes, QuinKill Max should be used with a surfactant, such as Spreader Sticker. It is a post emergent labeled to kill crabgrass. When used on St. Augustine, we are unable to confirm what it will do since it is not a tolerable type of a turf.
