Abstract/Contents:"A bermudagrass fairway at Fox Squirrel Country Club in Brunswick Co., NC was used to evaluate rates and methods of application of four granular insecticides for control of the newly hatched nymphs of the tawny mole cricket. Plots 12 ft X 80 ft were established in an area showing damage from a moderate infestation and the treatments were randomly assigned with four replicates. Broadcast treatments were applied using a standard push type Lesco fertilizer spreader to deliver the appropriate amount of insecticide to the plots. All other treatments were applied using a tractor drawn Gandy® slit-seeder modified for granular formulation application and operating at 1.9 mph to place the materials one inch deep in the soil. Treatment took place on 21 Jul. The soil was 68°F (4 inch) and moist at the time of application. Soil type was mineral with 0.5% humic matter and a pH of 5.2. The entire test was irrigated with 0.5 inch of water after the chemicals were applied. Pretreatment sampling showed the presence of young nymphs. Plots were evaluated on 9, 18, 25 Aug and 8 Sep (19, 28, 35, and 49 DAT, respctively). Damage evaluations were conducted using a damage rating grid (Dr. Pate Cobb, Auburn University) divided into 9 squares. Plots were evaluated by randomly placing the grid in each plot and examining each subsection of the grid for fresh damage. A damage rating is given from 0 to 9 depending on the number of squares that contain fresh damage. This was done twice in each plot and the damage averaged. All data were transformed √(x + 0.5) prior to analysis. Actual means are presented in the table. At 19 DAT, all treatments with the exception of the bifenthrin 0.2G formualtions provided a reduction in mole cricket damage as compared to the untreated plots. Evaluation of plots at 28 DAT gave similar results with the exception that the bifenthrin 0.2G (CAS) formulation at the 0.2 lb AI/acre rate showed significantly less damage than either the untreated control or the other bifenthrin treatments, but provided less control than all other treatments. Damage evaluation at 35 DAT gave similar results to the two previous evaluations. The low rate of bifenthrin on the CAS carrier was the only bifenthrin treatment that had less damage than the untreated, but it did not show significantly less damage than the high rate of the same formulation. All other insecticides tested provided excellent control. At 49 DAT, there were no significant differences between damage in the untreated and the bifenthrin treated plots. All other treatments had significantly less damage with the 10 lb AI/acre Mocap 10G subsurface treatment providing significantly better control than the same rate of Mocap 10G applied to the surface. There was no apparent phytotoxicity in any of the treatments."
