EVALUATION ACELEPRYN AND HGW86 GRANULAR FERTILIZER FORMULATIONS FOR CONTROL OF BILLBUGS, 2012

Insecticides were evaluated for control of billbugs at a Kentucky bluegrass research area at the John Seaton Anderson Research Facility near Mead, Nebraska. Treatments were applied 3 May 2012 to 5 x 5 ft plots arranged in RCB design with 4 replications. Granular products were uniformly applied using a hand shaker. All treatments were irrigated with 0.25 in of water within 24 hours of application. Formulations were evaluated 54 days after treatment (DAT) (26 June) by removing from each plot three, 8-inch diam turf-soil cores (1.05 ft2 total area) to a depth of 3 inches and counting the number of billbug larvae and pupae. Plots were periodically assessed for phytotoxicity. Environmental conditions at the time of treatment were as follows: soil moisture 16.1%; air temp 70oF; soil temp 65oF; relative humidity 78%; wind velocity 8 mph.
