Biological Control of Annual White Grubs with Entomophagous Nematodes, 1992
This study was conducted in Lincoln, NE on a perennial ryegrass golf course fairway. The turf (99% perennial rye) was maintained at a mowing height of 1.6 cm and thatch accumulation (finger compressed) in the plot area was 0.64 to 1.3 cm. Field conditions at the time of application were: air temperature, 20°C; soil temperature (10-cm depth), 23.9°C; soil type, silty clay loam; soil organic matter, 3-5%; soil pH, 6.0 to 7.0; water pH, 7.0; soil moisture, 18%. Plots were 3.05 x 3.05 m and the experimental design was a RCB with 4 replications. Insecticides were applied 12 Aug. Treatments were applied with a CO2 sprayer using a LF-4 nozzle at 165.5 KPa and delivering 18.9 liter spray/93 m2. The test area was irrigated prior to applications with 0.64 cm of water and periodically syringed during treatment. Immediately following applications, plots were irrigated with approximately 1.3 cm of water. Treatments were evaluated 21 DAT on 2 Sep by removing from each plot nine, 20.3 cm diam turf-soil cores (0.3 m2 total area) to a depth of 7.6 cm and counting the number of surviving grubs.
