| Abstract/Contents: | "A putting green in Monson, Massachusetts was chosen for the trial because of a relatively high population of Hoplolaimus and Tylenchorhynchus. The turf was a mixture of annual bluegrass and creeping bentgrass. The putting green, approximately 80 years old, was built on native clay soil and top-dressed with a sand-based material for at least 25 years. Mechanical analysis of the top 4 in of soil showed it to be 72.9% sand, 21.7% silt and 5.3% clay. USDA criteria classify this as a sandy loam based on the sand subfractions. The green was mowed, fertilized, watered and cared for consistent with standard golf green management practices. Plots were 6 x 6 ft, five replications per treatment, and completely randomized. Safe-T Green was sprayed on the foliage at the rate of 0.75 oz in 1.5 gal water/1,000 ft². 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). DiTera was drenched into the plots at the rate of 1.16 lb/1,000 ft². DiTera is a 95% formulation consisting of dried fermentation solids and solubles of Myrothecium verrucaria (Abbott Laboratories, Long Grove, IL 60047). Both treatments were applied on 10 Jun, 9 Jul and 14 Aug. No additional water was applied. For nematode assays, ten subsamples per plot were collected with a 1 in soil 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. Plots were evaluated for color and thinning during each collection date. Tylenchorhynchus populations were unusually high in the beginning of the year. The Safe-T Green treatment plots showed a drop in population on the 13 Aug collection, although it was not significant at p=0.1%. This drop in population in the Safe-T Green treatment was not sustained over the next two collection dates. The DiTera treatment also showed a drop in population that was not statistically significant. No differences in turf color or thinning were apparent among the treatments. Neither Safe-T Green or DiTera provided significant reduction of plant parasitic nematodes." |
