Abstract
Abstract Three granular insecticides were evaluated for the control of mole crickets on the bermudagrass fairway of the 10th hole at Fox Squirrel Golf and Country Club in Brunswick County. The test area was showing damage from a moderate infestation prior to treatment. Plots 16 ft × 75 ft were established and treatments were randomly assigned with four replicates. Surface broadcast treatments were applied using a standard push-type Lesco fertilizer spreader to deliver a weighed portion of chemical to the broadcast plots. All other treatments were applied using a tractor drawn Gandy® slit-seeder modified for granular formulation application and operating at 1.9 mph. Subsurface treatments were applied on 18 Aug and surface treatments were applied the following day. Soil was moist from rain the night of the 17th. Air temperature was 88°F and soil temperature was 84°F. Soil type was mineral with 0.9% humic matter and a pH of 6.1. The test area was irrigated with 0.5 inch of water after the chemicals were applied. Plots were evaluated for fresh damage on 1 Sep (14 DAT) and 15 Sep (21 DAT). Damage evaluations were conducted by using the damage grid method as developed by Dr. Pat Cobb, Auburn University. Five random damage ratings (0—9) were taken from each replicate and an average rating for the plot was determined. All data were transformed Vx + 0.5 prior to analysis.
