| Abstract/Contents: | "A putting green in South Hadley, Massachusetts, was chosen for the trial because of a relatively high population of Hoplolaimus. Data were also collected for Tylenchorhynchus. The turf was a mixture of annual bluegrass and bentgrass. The putting green, approximately 70 years old, was built on native clay soil, with an upper layer of 3 to 4 inches of sandy soil. Mechanical analysis of the top 4 inches of soil demonstrate it to be 83.6% sand, 11.9% silt and 4.5% clay. USDA criteria would classify the soil as a loamy coarse sand based on the sand subfractions. Plots were 6 ft X 6 ft, six replications per treatment and completely randomized. Treatments consisted of two rates of the experimental nematicide ASC-66824, one rate of Nemacur, and an untreated control. Treatments were made on May 22, 1992. Ten subsamples per plot were taken monthly, bulked, and extracted twice. Nematodes were recovered by wet sieving/sugar flotation and identified to genus. The data were subjected to a one-way analysis of variance and a test of LSD. No phytotoxicity occurred from any of the treatments. No differences in turf health were noted between treatments on any of the extraction dates. Both rates of ASC-66824 and the Nemacur treatment resulted in statistically lower populations of Hoplolaimus and Tylenchorhyncus. A statistically significant reduction of Hoplolaimus was noted on 6 Jul and remained so for the rest of the season. For Tylenchorhynchus, a significant reduction was noted on 8 Jun and continued until 8 Oct. The population level of Hoplolaimus in the control plots was sufficiently high by Aug to cause discernable damage during most growing seasons. However, during 1992, soil moisture was abundant and air temperatures were cool, excellent conditions for growing cool-season grasses." |
