I live in South Carolina and would like to know if tenacity can be applied to dormant centipede over winter while weeds are growing in dormant grass.
As you probably know, Centipedegrass is a very sensitive species of turf so many products that eliminate the crabgrass and other weeds can also cause damage to your lawn. Tenacity is a great pre-and post-emergent herbicide that will control crabgrass along with many other types of weeds and listed safe for centipede lawns. When used for post emergent control of actively growing weeds, a non ionic surfactant is recommended for best results. The surfactant is not needed for pre emergent applications. Turf Mark Blue can be tank mixed to allow you to see where you have treated and to ensure thorough coverage and avoid overlapping. Review the Tenacity product label and apply as directed to avoid possible injury to your turfgrass. Keep in mind, this is a strong herbicide so any overmixing, overapplying or applying when centipede is transition in or out of dormancy can injure the lawn. Some whitening of the weeds and turfgrass is normal as this is part of the weed killing process, but the color will return in 3-4 weeks at most or after the next 1-2 mowings.
