| Abstract/Contents: | "Six different active ingredients were tested for efficacy against European chafer larvae on a lawn in eastern Massachusetts (Waltham). The lawn consisted primarily of Kentucky bluegrass (30%), annual bluegrass (25%), perennial ryegrass (25%), and assorted broad-leaved weeds (20%), mowed at ca. 2 inches. Treatment plots were 8 ft X 8 ft, replicated 5 times, arranged in a CRB design. All applications were made between 11:45 AM and 1:00 PM 9 Aug. Liquid formulations were applied by hand with watering cans, 3 liters water per plot. Granular formulations were applied using glass jars with perforated lids. Conditions at the time of application were as follows: 85°F, sunny with light south wind (<5 mph), moderate humidity; soil type, silty loam; soil pH 6.2, water pH, 6.8. All plots received ca. 0.25 inch irrigation immediately after the last materials were applied. No additional rain fell in the area in the next 48 hr. Product efficacy was evaluated 28 Sep (50 DAT) by removing 4 cupcutter plugs (4.25 inch diam.) from near the center of each plot, dislodging soil with a hand trowel, and counting all grubs to a depth of 3 inches. All materials reduced grub populations significantly relative to the untreated check. In the two instances where two formulations of the same active ingredient were tested (Turcam and Merit), there was no significant difference between the formulations. All materials provided 'acceptable' (>80%) levels of control." |
