| Abstract/Contents: | "A bermudagrass fairway at Brierwood Golf Course in Shallotte was chosen to evaluate rates and methods of application of several granular insecticides for control of the newly hatched nymphs of the tawny mole cricket. Plots 18 ft x 95 ft were established and treatments were randomly assigned with four replicates. The broadcast treatments were applied using a a standard push type Lesco fertilizer spreader to deliver a weighted portion of insecticide to the broadcast plots. All other treatments were applied using a tractor drawn Cannaan TG70 subsurface granular applicator and overseeder (Cannan Industries, Inc., Dothan, AL) to place the materials one inch deep in the soil. Treatment took place 28 Jul for all subsurface treatments, 29 Jul for all surface treatment except for the Mocap (7.5 lb [AI]/acre) and the Crusade (4.0 lb [AI]/acre) surface treatments which were applied on 4 Aug. Air temperature was 100 degrees F. The soil temperature was 90 degrees F and moist at the time of application. Soil type was mineral with 1.5% humic matter and a pH of 6.1. 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 11 (14 DAT) and 25 Aug (28 DAT). Damage evaluations were conducted using the damage grid rating method as developed by Dr. Pat Cobb, Auburn University. Plots were evaluated by randomly placing a grid divided into 9 subsections 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 5 times/plot and the damage averaged. All data were transformed square-root(X + 5) prior to analysis. Actual means are presented in the table. All treatments except the high subsurface rates of Pennington 0.2G and EXP60818A provided a reduction in mole cricket damage as compared to the untreated plots at 14 DAT. In addition, all other insecticide treatments were more effective than either of the the low rate subsurface treatments of Pennington 0.2G or EXP60818A. At this date, the 10.0 lb AI/acre treatments (surface and subsurface) of Mocap 10G appeared to give the best control. At 28 DAT, all treatments were significantly different from the untreated plots with only the high subsurface rate of Pennington 0.2G giving less control than the other treatments. While the low subsurface rate of Pennington 0.2G seemed to provide slightly less control it was not significantly different from the control provided by the subsurface treatments of Turcam 2.5G, ASC-66824, or EXP60818A. In most cases, surface application appeared to give equal or better control than the subsurface treatments." |
