Abstract:Dolomitic limestone (4,844 kg/ha) was applied to designated turf plots on one of two dates and isofenphos (2.24 kg [AI]/ha) was applied on one of two subsequent dates to determine whether lime applications interfered with subsequent isofenphos applications. Some plots received lime only or isofenphos only. Isofenphos was applied on each date in three formulations (2F, 1.5G, 5G). The test was conducted once in the spring and again in the summer. All spring isofenphos applications reduced Japanese beetle (Popillia japonica Newman) grub populations significantly. Four of nine early applications of isofenphos made in the summer test reduced grub populations significantly, while none of the nine late applications of isofenphos made in the summer test reduced grub populations significantly. Prior lime applications did not result in a significant reduction in isofenphos activity compared to the corresponding isofenphos-only treatment.
