| Abstract/Contents: | "One rate of Exhibit (Steinonema carpocapsae) was compared to the standard Dursban for control of annual bluegrass weevil on a golf course fairway in Rutland, VT. Treatments were applied 21 Jun and rated 30 Jun. Plot size was 10 x 10 ft in a RCB design with a 3 ft buffer between plots. Treatments were applied with a watering can at a volume of 3.5 gal/1000 ft2. Treatments were applied between 1000 and 1400 h. All plots were immediately watered in with 0.2 inches water after application. Plots were evaluated by removing 3 plugs (0.1 ft2) per plot and counting larvae and pupae in the laboratory. At the time of sampling, the population was predominately 5th instar and pupae. At the time of application conditions were: soil temperature at 1 inch depth, 70.5 degrees F; thatch 0.25 inch; soil pH, 4.8; texture, loam, 47% sand, 43% silt, 10% clay; OM, 7.5%; moisture, 26.7%, sky, cloudy; air temp, 75.1 degrees F; previous 24 hr precipitation, 0.7 inch. Data were converted to larvae/ft2. Both Dursban and Exhibit significantly reduced larval populations. Exhibit performed as well as Dursban in this trial and has potential as a biological control agent for the annual bluegrass weevil." |
