Bermudagrass (Cynodon dactylon), a warm-season perennial grass, increasingly has become a problem in Kentucky cool-season turfgrass. Over much of the lower Southeastern United States, bermudagrass is the king of the turfgrasses. Celebrated for its aggressive growth habit, quick recovery, and ability to tolerate low mowing heights, bermudagrass can be found everywhere from high-end golf courses and prestigious sports stadiums to home lawns.

AGR-270: Restoring a Flood-damaged Lawn

Kenneth Clayton, Paul Rideout, Jason Vaughn, Beth Wilson | Mar. 14, 2023 (New)

Flooding across Kentucky has been an increasing problem in recent years and has caused significant damage to many properties, including home lawns. The deterioration or death of turfgrass is often caused by grass being smothered with silt and sand deposits left from the flood or grass being submerged under water for prolonged periods. Lack of oxygen to the plant can cause death when submerged, and the rate of death is often worse with higher water temperatures. Repairing these areas is important for reducing chances of erosion as well as allowing a return to the regular use of the lawn.

AGR-272: Preemergence Herbicides for Kentucky Lawns

Kenneth Clayton, Jason Vaughn, Beth Wilson | Feb. 16, 2023 (New)

Herbicides are used to control unwanted plants in many different locations. Postemergence herbicides are sprayed on actively growing weeds. In turfgrass, several herbicides are used to control weeds before they germinate and begin to grow. These are called "preemergence herbicides" and are commonly sold as "weed preventers." They control germinating weed seeds and subsequent growth. Therefore, to be effective, preemergence herbicides must be present in the upper soil surface before weed seeds germinate.
