Abstract/Contents:This study was conducted on a Kentucky bluegrass golf course rough in Lincoln, NE. Plots were 1.1 x 4.6 m and the experimental design was a randomized complete block with 4 replications. White grub infestation levels in the test area were high, (60.9/.09 m²) and injury to the turf was substantial at the time of application. Pretreatment counts indicated (5%) first (35%) second and (60%) third instar SMC/0.09m². All insecticide treatments provided statistically significant reductions in the white grub numbers. Subsurface applications of both grannular and liquid Dursban formulations resulted in greater white grub control than conventional broadcast applications, even when applied at the 0.45kg (50%) rate. The included chart lists the rate, application method, average number of southern masked chafer, and percent control for 9 different treatments.
