| Abstract/Contents: | "Deltamethrin (Deltagard SC) was applied alone or in combination with imidacloprid (Merit) or chlorpyrifos (Dursban Pro) to golf course fairway turf in the spring of 1998 to determine the efficacy of ABW. This test was conducted at Sleepy Hollow C. C., Scarboro, NY. All plots were treated on 14 Apr (sunny, calm, air temp 50°F, soil temp 48°F at 2 inches). Soil pH was 6.4, buffered pH 6.8, CEC 20.3 Meq/100 g. Treatment plots were 6 ft x 6 ft, replicated five times, and arranged in a CRB. Two sets of plots received an additional application on 27 Apr (sunny, light north breeze < 5 mph, air temp 44°F, soil temp 40°F). All liquid applications were made with a watering can using 3 qts water per plot. Granular products were applied with a glass shaker jar with perforated lid. Plots were watered in with 0.1 to 0.2 inch irrigation within 1 hr after application. Product efficacy was evaluated on 8 Jun by removing 12 cores, 1.85 inches diam, from near the center of each plot. Cores were transported to Amherst, MA, where they were broken apart manually and inspected under 10 X magnification. Insect counts were recorded for 3 cores at a time (4 observations per replication, 20 total observations). While all stages were recorded, only larvae, prepupae, and pupae (labelled as 'larvae' in the table below) were included in statistical analyses, because teneral adults are much more mobile than the immature stages. The insect populations in the untreated plots were at or above the commonly accepted threshold populations (30-40 larvae/sq. ft.) for this insect, and some of the untreated plots showed evidence of insect feeding activity. Every treatment except the lowest rate of Deltagard SC alone reduced populations significantly relative to the untreated check. There was no difference between 'split applications' and single applications of the higher rate of Deltagard, nor was there any enhancement of performance in the 'tank mixes'. The only difference in performance of the liquid and granular formulations of Deltagard occurred at the lowest rate of application." |
