Abstract/Contents:"The study was conducted on an irrigated Kentucky bluegrass fairway at Lakeside golf course, Lexington, Ky. The initial infestation was ca. 5 third stage grubs per ft2. Thatch accumulation was negligible. The experimental design was a RCB with 4 replications. Individual plots measured 8 X 8 ft with a 1 ft boundary between each plot. Granular applications were mixed with sand and applied by hand. The 1 liquid application was mixed with water at the proper rate and applied with a 2 gal pressurized sprayer with a cone-type nozzle. Some materials were prepackaged in pressurized hose-end applicators. All treatments were applied on Aug 31. Those applications that were to be irrigated were watered in using the golf course irrigation system. Approximately 1.5 inches of water (pH 7.14) was applied. Those treatments that were not to be watered-in were applied ca. 2 h later, after the turf had dried. Additional irrigation was withheld from the experimental site for 48 h. Surviving grubs were sampled 3 wks later by taking four 0.33-ft2 by 2-inch-deep soil cores from each plot. The cores were broken apart by hand and the grubs counted. Because the variances were proportional to the squares of the treatment means, a logarithmic transformation was used prior to ANOVA. The grub counts were extremely variable from sample to sample within plots, and between replicates of the same treatment. Only 1 treatment, hose-end applied Oftanol at 2 lb a.i./acre, reduced grub populations relations to the untreated check. No phytotoxicity was evident with any treatment."
