Abstract/Contents:"Replicated plots were treated with TCA at rates of 5, 10, 15, 25, 30, 35 and 40 pounds of acid per acre. Plots were located on a golf course of blue grass heavily infected with crab grass. Treatments were applied on July 3 at which time emergence of crab grass seedlings had started. Some burning and discoloration of the blue grass was noted on all plots treated. On plots receiving 5 and 10 pounds per acre the blue grass was not permanently injured and appeared normal some 10 days after treatment. Heavier applications destroyed or at least partially destroyed blue grass. Plots receiving 30, 35, and 40 pounds of TCA are free of any green shoots on plants except for dandelion and buckhorn plantain. Applications of 5 pounds of TCA reduced the stand of crab grass. A 90% kill was estimated. Only a few plants of crab grass survived on plots receiving 10 pounds of TCA. Later applications made after crab grass became established and well rooted did not show promise as a selective killer of crab grass in Kentucky Blue grass sod."
