Surfactant Evaluation for Mole Cricket Control on Golf Course Fairways, NC, 1992:

Abstract

Two rates of Orthene 75S and three surfactants were evaluated for mole cricket control on a Bermudagrass fairway at Oak Island Golf Course in Brunswick Co. Plots 45 ft wide X 70 ft long were established in areas where damage was evident. Randomly assigned treatments with three replications were used for the test. Soil had 0.2% humic matter and a pH of 5.9. The plots were pre-irrigated with 0.25 inch of water and treated on 19 Oct. Soil temperature was 68°F, air temperature 60°F, and the chemicals were applied late in the day with a Broyhill® fairway sprayer using 8006 nozzles at 40 psi. The chemicals were not watered in and the night of treatment was cool. Plots were evaluated by taking five random m2 grid samples/replicate. The grid was placed randomly and fresh damage observed in each of the nine subgrids (0 = not damage, 9 = severe damage) was recorded. Data presented are the avg of 15 ratings made/treatment for each sampling date. Evaluations were conducted on 27 Oct (8 DAT) and 6 Nov (18 DAT). All data were transformed X + 0.5. Actual means are presented in the table.
