| Abstract/Contents: | "The test was conducted on an established bermudagrass ('Tidwarf') putting green built to USGA specifications in Statesboro, GA. The green has had a severe sting nematode problem for several years. The test consisted of eight treatments applied to 4-ft x 4-ft plots in a randomized complete block design with four replications. Treatments included an untreated control, a Nemacur 10G control, and four DiTera WDG treatments with varying rates and numbers of applications. All management and chemical inputs were identical among plots except nematicide applications. Nemacur granules were spread by hand over nemacur-treated plots and then watered in with 1.5 gal water. DiTera was applied by dissolving the granules in 1.5 gallons of water and then applying water to plots. Nemacur and initial DiTera treatments were applied on 14 May. Additional DiTera applications were made 12, 26, 43, and 54 days later as required by the treatment list. Plots were irrigated as needed. Soil samples for nematode analysis were collected from the center 4 ft² of each plot to provide a buffer between adjacent treatments. Soil samples were collected prior to initial treatment application on 14 May, and on 9 Jun (26 days after initial treatment [DAIT]) and 21 Jul (68 DAIT). A subjective turf quality rating was made of each plot 26 and 68 DAIT. Analysis of variance indicated no differences among treatments in sting nematode population levels or turf quality ratings at any sampling date although the untreated plots consistently had the lowest turf quality rating (numerically). Nemacur's lack of efficacy may have been caused by enhanced microbial degradation of Nemacur occurring in the test site. DiTera was not phytotoxic to bermudagrass at the rates and application frequencies tested, nor did it leave any visible residue on the turf." |
