| Abstract/Contents: | "Halofenozide (Mach-2) at 1.5 or 2.0 lb (AI)/acre and imidacloprid (Merit^D]T^D]M) at 0.3 lb (AI)/acre were applied on one of two application dates and tested for efficacy against European chafer and oriental beetle larvae on a home lawn at the Suburban Experiment Station, Waltham, MA. The lawn consisted of 30% crabgrass (Digitaria sanguinalis), 30% perennial ryegrass, 20% Kentucky bluegrass, 20% dandelion (Taraxacum officinale L.), and was mowed at ca. 1.5 inches throughout the growing season. Treatment plots were 8 x 8 ft, replicated five times, arranged in a CRB. Applications were made on 21 Jul or 12 Aug. Liquid formulations were applied by hand with a watering can using 3-4 liters of water per plot. Granular products were applied by hand using a shaker jar. Soil conditions at the study site at time of application were as follows: soil type, silty loam; soil pH 6.1; CEC 20.4 Meq/100 g. The calcium to magnesium ratio was ca. 5:1. Plots were watered in with 0.1 inch irrigation though overhead irrigation immediately after application. Product efficacy was evaluated for all treatments on 22 Oct (93 and 71 DAT, respectively) by removing 5 cup cutter plugs (4.25 inch diameter) from near the center of each plot, dislodging soil and counting all grubs to a depth of 3 inches. All treatments reduced European chafer populatios [populations] significantly, although several of the Mach 2 treatments did not provide agronomically acceptable levels of control (ca. 60-80% reduction). For oriental beetles, all treatments except the early application of the granular formulation of Mach-2 reduced larval populations significantly relative to the untreated check. Again, however, several of the Mach-2 treatments failed to provide agronomically acceptable levels of control of oriental beetles. In no case was there a significant difference between rates of application of a given formulation on a given date of application." |
