Abstract/Contents: | "Plant parasitic nematodes can be a limiting factor in the production of high quality bermudagrass (Cynodon spp.) putting greens. A 3-year study was initiated in May 1978 on Dothan sandy loam (fine-loamy, siliceous, thermic Plinthic Paleudult) to determine the effects of N sources, core aerification, vertical mowing, and topdressing on plant parasitic nematode populations. Nematode populations were determined in the fall of 1978 and 1980 and in the spring of 1979, 1980, and 1981 by a modified flotation sieving technique. Stubby root (Trichodorus spp.), ring (Criconemoides spp.), stunt (Tylenchorhynchus spp.), and spiral (Helicotylenchus spp.) were the principal nematodes present. Differences in overall populations of nematodes due to N treatment occurred only in the Spring 1980 sampling. Lower populations occurred where activated sewage sludge was the source on N than where NH4NO3 was applied. Topdressing, vertical mowing, or core aerification treatments had no consistent effects on nematode populations. Interactions occurred between bermudagrass cultivars and nematode species. 'Dothan' selection supported higher populations of stunt and stubby root nematodes than did 'Tifdwarf' or 'Tifgreen'. In contrast, Tifdwarf and Tifgreen supported more spiral nematodes than Dothan. Tifdwarf supported the greatest overall plant parasitic nematode population." |
