| Abstract/Contents: | "The experiment was conducted on a golf course fairway rough in Amherst, NH. The experimental design was a RCB, replicated 4 times with 8 x 8 ft plots. Treatments were applied 3 Sep and rated 24 Sep. At the time of application, JB [Japanese beetle] were predominantly 2nd instar. Nematodes and Triumph were applied with a watering can in 5 gal/1000 ft2 at 1700 h. Nematodes were checked for viability before application. Treatments were not watered in because it was unnecessary due to the high soil moisture and rain. The plots were irrigated as necessary throughout the trial period to maintain good soil moisture. These plots hadn't received any other insecticides for at least 1 year previously. Plots were rated by counting the number of live grubs per 2.25 ft2 of turf. Conditions at the time of treatment were: air temperature, 55.4 degrees F, 1 inch depth 62 degrees F, 2 inch depth, 62.7 dedgrees F; soil pH, 5.8; slope, 0% soil texture, loam, 43% sand, 47% silt, 10% clay; soil organic matter, 6.8%; soil moisture, 24.8%; precipitation, drizzle for 8 h pretreatment and 14 h posttreatment. The standard, Triumph was the only treatment which gave good control. All three Biosis [Biosys] nematode treatments performed poorly. However, the increase in control with higher rates suggest that the rates used were too low." |
