Abstract/Contents:"A trial was conducted at Oak Island Golf and Country Club (Brunswick Co.) to determine the efficacy of two rates and two formulations of Merit insecticide (NTN33898) as a preventitive residual treatment for control of mole crickets. Test plots (20 ft x 20 ft) were established on the bermudagrass fairway of hole 17 in an area which has a history of mole cricket problems. Treatments (3 replicates) were applied on the morning of 1 Jul after a light irrigation of the plots. Sprays were applied with a CO2 powered backpack sprayer using 8002 nozzles and operating at a pressure of 40 psi. Granular treatments were applied using shaker jars to deliver appropriate amounts of insecticide to each plot. Air temperature was 84 degrees F and soil temperature was 79 degrees F. The sandy mineral soil had 0.1% humic matter and a pH of 6.3. Fairway irrigation was used to wet the soil to a depth of 0.5 inch, immediately after application. Nymph counts were made on 21 Jul (20 DAT) by using soapy water flushes to sample three 1 m2 areas/plot and recording the number of nymphs recovered. Damage evaluations were made on 27 Jul (26 DAT) and again on 11 Aug (41 DAT) by taking three grid damage ratings (0-9) plot. Actual means are reported in the table. All data were transformed squareroot(X + 5) prior to analysis. Soap flushes reveal that only the high rate of the Merit granular formulation, the low rate of the Merit WP and Mocap 10G were significantly different from the untreated after 20 days. The first damage grid evaluation (26 DAT) showed both Merit 75WP treatments and the Mocap treatment to be significantly different from the untreated plots. Damage evaluation at 41 DAT produced results similar to the 20 DAT nymph counts. No phytotoxicity was observed."
