The objective of this study was to evaluate the efficacy of severalinsecticide rates and timings against Putnam Scale on blueberry.Six bush plots were established in a 8-year-old ‘Blue Crop’ blueberryplanting (row spacing 12′ × 4′) located at the Trevor NicholsResearch Center in Fennville MI (Blue Crop Block). There werefour replicated plots per treatment, set up in an RCB design. Testmaterials were applied with an FMC 1029 tractor-mounted airblastsprayer calibrated to deliver 50 GPA at 2.5 mph. Rates and timingsof test materials are as outlined in Table 1. In addition, regular maintenancefoliar applications were applied to all treatments includingAbound F, Alliette WDG, Indar 2F, Luna Tranquility F, and PristineDF. Also, Callisto L and Karmex 80DF were banded below the rowsfor weed control.
