Abstract/Contents:"Lambda-cyhalothrin (Scimitar or ICIA 0321T) was applied to golf course fairway turf in the spring of 1998 to determine the efficacy against ABW. Three other pyrethroids - bifenthrin (Talstar), cyfluthrin (Tempo), and deltamethrin (Deltagard) - were included in the study for comparison. This test was conducted at Sleepy Hollow C. C., Scarboro, NY. All applications were made on 27 Apr (sunny, light north breeze < 5 mph, air temp 44°F, soil temp 40°F at 2 inches). Soil pH was 6.4, buffered pH 6.8, CEC 8.3 Meq/100 g. Treatment plots were 6 ft x 6 ft, replicated five times, and arranged in a CRB. All applications were applied with a watering can using 3 qts of water per plot. Plots were watered in with 0.1 to 0.2 inch irrigation within 1 h after application. Product efficacy was evaluated on 8 June by removing 12 cores, 1.85 in 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, (DMRT, P = 0.005), because teneral adults are much more mobile than the immature stages and might have migrated into treated plots 6 to 8 wks after application. The insect populations in the untreated plots were below the commonly accepted threshold populations (30 - 40 larvae/sq. ft.) for this insect, and none of the plots showed evidence of insect feeding activity. Every treatment reduced populations significantly relative to the untreated check, but there was no difference in performance among any of the treatments at the rates tested. This study seems to confirm evidence from similar studies in previous years that the synthetic pyrethroids currently labelled for use on turf are effective against bluegrass weevils if applied at the right time (targeting adults as they begin ovipositing)."
