| Abstract/Contents: | "Three experiments were conducted in 1995 to evaluate the control of smooth crabgrass after emergence into a mature stand of predominately perennial ryegrass (Lolium perenne L) turf. Two of the studies were conducted when the crabgrass was in the pre-tillering stage (applications made on June 21 and June 23 with sequential applications for selected treatments 14 days later). One study was indicated on July 6 (after crabgrass had begun to tiller). Treatments were applied using a hand-held boom CO₂ powered sprayer with two 6504 nozzles at 30 psi calibrated to deliver 80 gpa. All experiments were rated for crabgrass control on August 19, 1995. Treatments that provided acceptable control (85%) where crabgrass was in the pre-tillering stage included several different pendimethalin and fenoxaprop combinations (individual rates undisclosed). Both the low and high rate treatments provided acceptable control. Dittiopyr at 0.5 lbs. ai/A and MSMA at 2.0lbs. ai/A 14 days later did not control crabgrass at an acceptable level (82% and 77% respectively). None of the treatments used in the post-tillering experiment controlled crabgrass at an acceptable level. However, pendimethalin plus fenoxaprop at 1.5 and 0.25 lbs. ai/A respectively provided 70% control from one application." |
