| Abstract/Contents: | "An area of non-irrigated rough at The Country Club of Jackson in Jackson County, MI, was used for this test. Plots were 4 x 4 ft separated by a 2 ft wide buffer strip. The area in which the test was conducted has been infested with European chafer grubs for more than 7 years. The treatments were all replicated six times. Most of the roughs on the course were treated with Dylox G during the fall of 1997 and 1998. No insecticides were used on the roughs in 1999 other than our experimental treatments. The plot area was checked at dusk in mid-Jun for adult activity. More than 1000 adult European chafers were observed in a 10 minute period. Rain during the last week of Jun and the first week of Jul also made the site very attractive to Japanese beetle. Plots were laid out on 2 Jul and Mach 2-SC and Merit 75 were applied. 6-6-0 w 0.86% Mach-2 and 24-5-11 w 0.86% Mach-2 were applied on 8 Jul. All treatments were applied on 8 Aug to fresh plots. liquid treatments were applied at 50 psi through a single nozzle hand-held CO₂ sprayer with a 8003 nozzle at a rate of 175 gpa of finished spray. Granular treatments were applied with a hand held "shaker." Treatments were made between 10:00 and 11:30 am. All the treatments depended upon rainfall for incorporation. Replications 1-3 were evaluated on 1 Oct and replications 4-6 were evaluated on 11 Oct. all the plots were evaluated by digging a ft² of each plot. All grubs were collected and brought back to the lab for identification. Merit and Mach-2 consistently gave much better control of the grubs when applied in early Jul than when they were applied on 8 Aug. Mach-2 as a liquid formulation was superior to the granular/fertilizer formulations. The dry Aug weather could have contributed to the reduction in efficacy of the Aug treatments. In dry years, it is advisable to apply Merit or Mach-2 in late Jun or early July for optimum efficacy." |
