Abstract
Abstract A grid of 4 ft by 4 ft plots separated by 1 ft wide buffer strips was established on a home lawn with an infestation of chinch bugs in Okemos, MI. On 23 Jul precounts were made by observing each 4 ft by 4 ft plot for a 2 min period, all larvae and adults were counted. The chinch bugs were determined to be in the 2nd to 5th instar at the time of the pre-spray sample and application. The treatments were grouped into blocks based on these counts. Six replications of each treatment were treated between 10:00 am and 12:00 pm on 23 Jul. Each 16 ft2 plot was considered a replicate. Granular products were evenly applied over the plot with hand-held shakers. Liquid products were applied with a single nozzle, hand-held CO2 sprayer from R&D Sprayers. Applications were made at 50 psi through an 8003 flat fan nozzle for 12 sec (175 gal/acre). The postcounts were made on 30 Jul in all plots. Each plot was observed for 6 min.
