| Abstract/Contents: | "A putting green in Barnstable, Massachusetts was chosen for this study because of a high population of Hoplolaimus and Tylenchorhynchus nematodes. The turf was a mixture of annual bluegrass and creeping bentgrass. Mechanical analysis of the top 4 in showed it to be 89% sand, 8% silt, and 3% clay. USDA criteria classify this soil as a sand. Twenty-five plots, 6 x 6 ft provided 5 replications for 5 treatments. Neo-Trol was applied by sprinkling the dry material on the plots. Neo-Trol consists of 100% ground sesame plant, Sesamum indicum (Parkway Research Corp, 13802 Chrisman Rd, Houston TX 77039). The conventional nematicide treatment was a single application of Nemacur at 2.3 lb/1,000 ft², applied 2 May. Five plots served as untreated controls. All plots received approximately 0.5 in irrigation following the 2 May treatments. Neo-Trol treatments applied after 2 May received a light irrigation. 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. The season provided excellent growing conditons for turfgrass. There were no differences in turf color or thinning among the treatments. Nemacur suppressed Criconemella populations but statistical significance was only seen in the Aug collection. Nemacur did not suppress Heterodera or Hoplolaimus (data not shown) but Tylenchorhynchus populations were significantly reduced. Criconemella populations were significantly suppressed in All Neo-Trol treatments in the Aug collection. Heterodera, Hoplolaimus and Tylenchorhynchus were not suppressed by Neo-Trol. Excessive label-rates of Neo-Trol do not appear to increase its effectiveness against plant parasitic nematodes." |
