The Little Leaf Lindens, River Birch on #9, New Burr Oak on #9, and Roses on the golf course were sprayed (photo on left) for Japanese Beetle (photo above) on Friday July 8th. The damage to the tree leaves has definitely slowed down, but for the insecticide to work, the beetles have to ingest part of the leaf. There are still large numbers of these beetles around in the roughs laying eggs. Along with European Chafer grubs, the Japanese Beetle grubs can also cause tremendous damage to turf roots later in summer if the populations are not controlled.
