GRCA to spray properties for gypsy moth caterpillars

To The Haldimand Press

BYNG—The Grand River Conservation Authority (GRCA) will be spraying an organic pesticide at a number of its properties to control growing populations of gypsy moth. Aerial applications are planned over susceptible forest areas at Byng Island, Pinehurst Lake, and Brant conservation areas, and at the Dryden Tract and the FWR Dickson Wilderness Area. Control of the current outbreak is required to protect and maintain affected forest areas and to reduce future hazard tree removals.

The organic insecticide Foray® 48B, whose active ingredient is a widely distributed soil bacteria called Bacillus thuringiensis kurstaki (Btk), will be applied by helicopter. Two applications will occur about three to seven days apart. Timing depends on insect and tree development, as well as weather conditions. It is expected that applications will occur between May 20 and June 10, 2020.
