Abstract A trial was conducted to determine the efficacy of two granular formulations of fipronil (EXP60818A and EXP60819A) applied at various rates for the control of mole cricket nymphs. Large (90 ft × 90 ft) plots were established on three infested fairways (#1, #3, #12) at the Fox Squirrel Golf and Country Club in Brunswick County. Treatments with three replicates were randomly assigned to the plots with one untreated area on each fairway and the plots were irrigated with 0.25 inch of water prior to chemical application. Weighed portions of each granular formulation were broadcast over the plots using a push type Lesco fertilizer spreader. All plots were treated late in the day of 26 Jul. Air temperature was 78°F and soil temperature was 89°F. After treatment, the plots were irrigated with 0.5 inch of fairway irrigation to water the chemicals into the sandy soil. Plots were evaluated by quantifying the fresh damage present using the grid method, as developed by Dr. Pat Cobb at Auburn University. A grid divided into nine equal sections was randomly placed in each plot and examined for the occurrence of fresh mole cricket damage. A rating of 0 thru 9 is given for each frame, depending on the number of sections in which fresh damage was observed. Ten damage grids were used to evaluate each plot on four dates: 12 and 25 Aug, 15, and 29 Sep. Plots were also evaluated on 14 Oct and 18 Nov using the grid method; however, on these dates two separate sets of five damage grid ratings were made in each plot. In order to obtain an estimate of reinfestation, one set of samples were taken from the center of each plot and the other from an area ca. 5 ft from the outside edge of the plot. All data were transformed Vx + 0.5 prior to analysis.
