| Abstract/Contents: | "Bendiocarb (Turcam^D]T^D]M), halofenozide (Mach 2^D]T^D]M), imidacloprid (Merit^D]Td]M), or trichlorfon (Dylox^D]T^D]M) were applied to a golf course rough in Stockbridge, MA., and tested for efficacy against Japanese beetle larvae. The turf consisted of 50% Kentucky bluegrass, 35% perennial ryegras, and 15% white clover, and was mowed at ca. 2.0 inches throughout the study period. Treatment plots were 8 x 8 ft, replicated five times, arranged in a CRB. Most applications were made on 16 Aug; trichlorfon was also applied to additional plots on 30 Aug or 13 Sep. Liquid formulations were applied by hand with a watering can using 3-4 liters of water per plot. Granular formulations 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 7.5; CEC 14.5 Meq/100 g. The calcium: magnesium ratio was ca 3:1. Plots were watered in with 0.1 inch of irrigation immediately after application. Product efficacy was evaluated for all treatments on 15 Oct (60, 46, or 32 DAT, respectively) by removing 5 cupcutter plugs (4.25-inch diameter) from near the center of each plot, dislodging soil, and counting all grubs to a depth of 3 inches. The population in the untreated check plots was 8.6 grubs/ft², which is within the commonly accepted range for "tolerance levels" for Japanese beetles in Massachusetts. All treatments reduced larval populations significantly relative to the untreated check, including the late season trichlorfon application. The weather in Sept and Oct was unusually mild, which presumable accelerated grub development." |
