| Abstract/Contents: | "An area of non-irrigated rough at The Country Club of Jackson in Jackson County, MI was used for this test. Plots, 4 ^D#x 4 ft, were separated by 2 ft-wide buffer strips. The area in which the test was conducted has been infested with European chafer grubs for more than 13 years, and Japanese beetle for the last 11 years. Treatments were all replicated six times and blocked from one end of the plot to the other. Plots were established on 16 May. Treatments were applied on one of the following dates: 16 May, 13 Jul, or 29 Aug. Liquid treatments were applied at 50 psi through a single nozzle hand-held CO2 sprayer with an 8003 nozzle at a rate of 175 gpa of finished spray. Granular treatments were applied with a hand-held "shaker". Treatments were made between 0930 and 1130 hours. All plots treated on a particular day were watered with 0.25 inch of irrigation after all applications were made. Replications 1-4 were sampled on 26 Sep and replications 5-6 were sampled on 5 Oct by digging 2 ft2 from each plot. Between 19 May and 12 Jul, 4.7 inches of rain, an additional 5.9 inches fell between 13 Jul and 28 Sep, and 2.3 inches of rain were recorded between 29 Sep and 5 Oct. The first 300 grubs were identified to species under a dissecting microscope. The ratio was 40% European chafer to 60% Japanese beetle. Number of grubs per sample was log transformed prior to a two-way ANOVA. Data were subjected to ANOVA and means were separated using an F-protected LSD (P ā¤ 0.05). In 2005 our grub plots at the Country Club of Jackson were heavily infested with Japanese beetle and European chafer. Mean density in control plots was 30.2 per sample (15.1/ft2). Most of the treatments in the test worked extremely well. All treatments applied prior to the Aug 29 applications gave 90% or better control. Of the treatments applied on Aug 29, Allectus and Arena gave the best level of control (75-81%), followed by Dylox and Merit (60-63%). Sevin and SA-130301 were not significantly different from the control." |
