Abstract/Contents: | "Goosegrass (Eleusine indica) and smooth crabgrass (Digitaria ischaemum) are problematic grasses in both warm and cool season turfgrass swards. Oxadiazon (RonstarĀ® is typically used in established turfgrass to control both goosegrass and crabgrass when applied preemergence in late winter or early spring. Indaziflam (Specticle Floā¢) is a new chemistry, released in 2012 by Bayer CropScience for annual grass control in warm season turfgrass. The objective of this trial is to evaluate preemergence (PRE) goosegrass and smooth crabgrass control with programs comparing oxadiazon and indaziflam in bermudagrass turf. This study was conducted at two locations in Virginia. The first, at the Independence Club in Richmond, VA, was initiated on March 26, 2012 on a bermudagrass driving range maintained at a fairway height of between 1.3 and 2.0 cm. The second location, initiated on March 28, 2012, was at the Turfgrass Research Center in Blacksburg, VA on a bermudagrass fairway maintained at a cutting height of 1.3 cm. Experimental design is a randomized complete block with 3 replications. Treatments included: Oxadiazon PRE at 3363 g ai/ha, indaziflam PRE at 49 g ai/ha, indaziflam PRE fb 60 days after initial treatment (DAIT) at 24 g ai/ha, and oxadiazon PRE at 3363 g ai/ha fb indaziflam at 60 DAIT at 24 g ai/ha. At the Richmond location, only goosegrass was evaluated. Overall goosegrass pressure was sporadic, and percent cover never exceeded 1% across all treatments, including the untreated check, and will therefore not be discussed. There was no delay in greenup or injury to the bermudagrass at this location. At the Blacksburg location, smooth crabgrass was evaluated. At 8 weeks after the initial treatment (WAIT), percent smooth crabgrass cover was 8% in the untreated check, and all treatments reduce smooth crabgrass cover 80%. At 16 WAIT, percent cover in the untreated check was 57%, and all treatments reduced smooth crabgrass cover 91%. At 22 WAIT, percent smooth crabgrass cover in the untreated check increased to 80%, and all treatments reduced smooth crabgrass cover 92%. At the conclusion of the study, smooth crabgrass populations were reduced by frost in late September and early October, but all treatments still reduced smooth crabgrass cover 89%. At both locations and all timings, no delay in greenup or injury to bermudagrass was observed. These results demonstrate the ability of oxadiazon alone, indaziflam alone, or combinations of the two compounds to provide season long smooth crabgrass control in Virginia." |
