Large Crabgrass Control in Turfgrasses with Fall-applied Herbicides1

  1. B. J. Johnson

Abstract

Abstract

Herbicidal control of both winter and summer annual weeds in turfgrasses usually requires fall and spring treatments which utilize excessive amounts of chemicals. Management studies were conducted for 3 years on common bermudagrass [Cynodon dactylon (L.) Pers.] at Griffin and Kentucky bluegrass (Poa pratensis L.) at Blairsville, Georgia, to determine the effectiveness of fall and fall + reduced spring rates of herbicides applied for large crabgrass [Digitaria sanguinalis (L) Scop.] control to minimize chemicals applied. The experiments were conducted on Cecil (Typic Hapludult) sandy loam at Griffin and Hatboro (Typic Fluvaquents) sandy loam at Blairsville.

Bensulide [0,0-disopropyl phosphorodithioate S-ester with N-(2-mercaptoethyly)benzenesulfonamide] was the only herbicide that consistently controlled at least 82%, of large crabgrass the summer after fall treatment. All other herbicides required fall and repeated spring treatments for consistent control.
