Spring Mole Cricket Control on Golf Courses in South Mississippi, 1992:

Abstract

Abstract This experiment was conducted on Fairways at the Jackson County Golf Course on the Gulf Coast. Soil type was sandy clay loam. Experimental design was a randomized complete block with 4 replications. Each replication was 10,000 ft2. Treatments were made on 1 May. A second (½ rate) application of Biosys #319 nematodes was made on 15 May to one treatment. All treatments were applied with a Snyder Polyolefin Agro-Tank tractor mounted hydraulic sprayer. Total spray volume was 50 gal water per acre using 8003 T-jet flat nozzles with 50 psi. Immediately before and after treatment, ⅓ inch irrigation water was applied to all plots except the Orthene treated plots. All plots were irrigated with ¼ inch of water each afternoon after treatment for four weeks. Rainfall of ½ inch occurred on 24 May and a trace of rainfall was recorded on 24, 27, 28, 29, and 30 May. At the time of application soil moisture was wet, soil and ambient temperatures were 75° and 85°, respectively. Relative humidity was moderate with a cloud cover of 20%. Mole cricket damage ratings were made using a I m2 frame divided into nine equal, square-shaped sections. The frame was placed on the ground in 20 locations/rep. The presence of mounds and tunnels was determined visually and by touch. Damage ranged from zero (no damage in any of the nine sections) to nine (nine sections contained mounds and/or tunnels). Pretreatment counts were made on 31 Apr and post-treatment counts were made on 15 and 29 May.
