| Abstract/Contents: | "A putting green in Northfield, Massachusetts consisting of a mixture of annual bluegrass and creeping bentgrass was chosen for this study. Top-dressing over the years has resulted in approximately 4 in. of sandy soil. Mechanical analysis of the top 4 in. showed it to be 74% sand, 21% silt, and 5% clay. USDA criteria classify this soil as a coarse sandy loam. All treatments were applied 18 May followed by approximately 0.5 in. irrigation. Twenty five plots, 6 ft x 6 ft provided five replications for 5 treatments. DiTera, 1.16 lb formulated product and Safe-T-Green, 0.75 oz formulated product/1,000 sq ft respectively were applied in combination as one treatment. A second combination treatment was the same as the first but with the addition of Neo-Trol, 10.54 lb. DiTera is a 95% formulation consisting of dried fermentation solids and solubles of Myrothecium verrucaria (Abbott Laboratories, Long Grove, IL 60047). Safe-T-Green consists of a 99.9% proprietary blend of linear secondary alcohols reacted with ethylene oxide (Safe Materials, Inc. P.O. Box 1065, Valdosta, GA 31603). Neo-Trol consists of a 100% ground sesame plant, Sesamum indicum (Parkway Research Corp, 13802 Chrisman Rd, Houston, TX 77309). A single treatment of Nemacur treatment consisted of a 18 May application followed by a 24 Jul application. Five plots served as untreated controls. For nematode assays, ten subsamples per plot were collected with a 1 in. soil sampling tube to a depth of 4 in. and bulked. Nematodes were recovered by wet sieving/sugar flotation and identified to genus. The data were subjected to analysis of variance and a test of LSD. Plots were evaluated for color and thinning during each collection date. There were no differences in turf color or thinning among the treatments. However in Jul, wilt was more prevalent on plots that had not received nemacur. Criconomella and Hoplolaimus populations were not suppressed by any treatments. Tylenchlorhynchus was suppressed by both Nemacur treatments by 7 Jul and by both combination treatments by 14 Aug." |
