| Abstract/Contents: | "The study was located on a bentgrass range 1 north at the Ohio State Turfgrass Research and Education Center, Columbus, OH. Treatments were applied on 4 Sep to plots 4 x 6 ft arranged in a RCB, replicated 4 times. Liquid treatments were applied using a CO₂ sprayer calibrated to deliver 2.0 gal/1000 ft². No immediate post-treatment irrigation was applied. The 100% creeping bentgrass range was mowed at 0.5 inch, had no thatch and was irrigated daily with 0.25 inch of water. On 5 Sep two 8-inch stainless steel cylinders were driven into the turf, about 2 hr after the last spraying to allow for complete drying of all treatments. Each cylinder was infested with six 5th- and 6th-instar BCW (1.0 to 1.25 inch) and covered with nylon screen. On 9 Sep (5 DAT), the covers were removed and each cylinder was flooded with a soapy water mix (15 ml Joy dishwashing detergent in 1.0 ga water) to flush out any live BCW. It was discovered that many of the larvae had pupated, so the turf cover was removed and the live pupae were added to the counts. Check survival was 92%. A good rate response in the spinosad treatments was achieved. No phytotoxicity was noted." |
