| Abstract/Contents: | "Several insecticides and a commercially available nematode preparation for biological control were evaluated for caterpillar control on a bentgrass practice green at Pine Hollow Golf Course in Johnston Co. Experimental plots 10 ft wide x 30 ft long were established. Treatments with three replications were randomly selected. Soil and air temperature were both 84 degrees F and soil moisture was adequate to preclude preirrigation. Spray formulations were applied to plots using a CO2-pressurized backpack sprayer operating a 40 psi using 8002 flat fan nozzles delivering approx. 30 gal of spray/acre. Screens were removed from the sprayer to apply the Exhibit nematode treatment. Granular formulations were applied using shaker jars with perforated lids. Mocap could not be used on the bentgrass due to phytotoxicity, and this treatment was applied to an adjacent area of the fairway. Treatments were applied 9 Sep under intermittently cloudy skies. After application, all treatments were irrigated in with approx. 0.25 inches of water. Larvae were mostly of medium size. Plots were evaluated at and 3 DAT by flushing three 1-m2 areas/plot with soapy water and taking counts of the emerging live worms. All data were transformed [square root] X + 0.5 prior to analysis. Actual means are reported in the table. Evaluations at 1 DAT showed all products tested except the Exhibit gave significant control of the cutworm infestation with Mocap 10 G giving 100% control and the Sevin 7 G and Dursban 4 E giving comparable control. There were no significant differences between the Exhibit counts and the control. At 3 DAT, worm counts indicated that the Exhibit had given 63% control, both Sevin formulations giving approx. 85% control, and both Mocap 10 G and Dursban 4 E giving 100% control of the infestation." |
