| Abstract/Contents: | Determined the reduction of dew formation and phytotoxicity of three wetting agents, Lesco's Lescowet A and B and Aqua Gro. Treatments were applied to a 10-year-old stand of Emerald creeping bentgrass, established on a 1:1:1 ratio of sand:soil:peat mix. The pH of this soil is 8.1 with available phosphorus and Potassium being 4 lb and 34 lb/acre, respectively. The plots were established in a randomized, complete-block design with three replications containing three control plots each . Products were applied at 4, 8 or 16 pounds per 1000 sq. ft. on June 24 and August 8, 1988. Dew reduction and phytotoxicity ratings are presented in tables On June 25, the first phytotoxicity data were taken. On June 27, a second set of data were taken. Phytotoxicity was observed on June 25, but no extreme damage was evident. Tip burn was present but was removed after three mowings. The 16-lb rate of Lescowet granular "A" and "B" produced the greatest amount of phytotoxicity. The 8-lb rate of granular "B" and 16-lb rate of Aqua Gro also produced some phytotoxic symptoms. On June 27, no unacceptable phytotoxicity was observed, and no significant phytotoxicity occurred after the second application. On August 9, the first dew reduction data were taken. This data suggested that all three products at the 16 lb and 8 lb/1000 ft2 rates were successful in reducing dew. The 16-lb rates received the highest rating while the 8-lb rates received a moderate rating. The granular "B" product at the 4-lb rate received an acceptable rating. One week later on August 15, granular "B", at the 16-lb rate was the only treatment which continued dew reduction at an acceptable rating. |
