| Abstract/Contents: | "A putting green in South Hadley, Massachusetts with Criconemella, Hoplolaimus and Tylenchorhynchus was chosen for this study. The turf was a mixture of annual bluegrass and creeping bentgrass. The putting green, approximately 75 years old, was built on native clay soil, with an upper layer of 3 to 4 in of sandy soil. Mechanical analysis of the top 4 in of soil showed it to be 83.6% sand, 11.9% silt and 4.5% clay. USDA criteria classify this soil as a loamy coarse sand based on the sand subfractions. Plots were 6 x 6 ft, 6 replications per treatment, and completely randomized. In 1996, treatments consisted of two rates of DiTera, one rate of Nemacur, and an untreated control. In 1997, only one rate of DiTera was applied. DiTera is a 95% formulation consisting of dried fermentation solids and solubles of Myrothecium verrucaria (Abbott Laboratories, Long Grove, IL 60047). The green was mowed, fertilized, watered and cared for consistent with standard golf green management practices. Plots were evaluated for color and thinning during each collection date. 1996 trial. DiTera was drenched into the plots at the rate of 1.16 lb/1.000 ft² and 2.32. lb/1,000 ft² of formulated product in 55.5 gal water. Nemacur 10G was applied once at the rate of 2.3 lb/1,000 sq ft. For nematode assays, ten subsamples per plot were collected with a 1 in coil sampling tube to a depth of 4 in, bulked, and extracted. 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. 1997 trial. 1997 treatment plots were the same as for 1997; however, only the 1.16 lb rate of DiTera was tested. All other treatments and methods were the same as for 1996. Results for 1996. There were no differences in turf color or thinning among the treatments. Criconemella populations were not significantly reduced by either DiTera or Nemacur. Hoplolaimus was significantly reduced (p= 0.1%)compared to the controls on both Aug collection dates. DiTera did not reduce Hoplolaimus populations. Tylenchorhynchus was not reduced by either the DiTera or Nemacur on any of the collection dates. Results 1997. There were no differences in turf color or thinning among the treatments. Criconemella and Hoplolaimus populations were not significantly reduced by either DiTera or Nemacur. Jul and Aug populations of Hoplolaimus in the Nemacur treatment are approximately half of the control treatments; however, plot to plot variability precluded demonstration of significant differences. Nemacur significantly reduced Tylenchorhynchus populations but DiTera did not. There was no apparent increase in efficacy with DiTera when applied for two successive growing seasons on the same plots. Nemacur also performed below expectations in this trial." |
