| Abstract/Contents: | "This study was located on bentgrass ranges 5 and 6 south at the Ohio State Turfgrass Research and Education Center, Columbus, OH. Treatments were applied on 11 Sep, 26 Sep, and 2 Oct to plots 5 x 8 ft arranged in a RCB, replicated 4 times. Liquid treatments were applied using a CO₂ sprayier calibrated to deliver 2.0 gal/1000 ft² and at 0.5 inch, had no thatch and was irrigated daily with 0.25 inch of water. Efficacy data for SWW larvae were taken 8 Oct by flooding a 1.0-yd² area using a soap solution consisting of 15 ml Joy dishwashing detergent in 2.0 gal water. On 9 Oct, a standard soil sampler was used to take 10 turf and soil cores from the remaining unflooded turf in each plot. Each core was placed in a vial and a single 2nd- or 3rd BCW larva was placed on the turf. The capped vials were kept at room temperature until 14 Oct (5 d) when surviving larvae were counted. Response of BCW and SWW to MACH2 and Tempo were different. A date of application response to MACH2 formulations was observed in the BCW bioassay. Field populations of SWW appeared to be more affected by early (27 d) applications of MACH2 but were equally affected by Tempo. No phytotoxicity was observed from any of the treatments." |
