Pesticide technicians and volunteers in the Capital Region finally got a weather break in early May. Taking advantage of a dry spring day—a requirement for pesticide treatments, and a rarity this time of year—they traveled into a 10-acre tract of the Plotterkill Preserve and sprayed about 250 trees in an attempt to slow down an infestation of hemlock woolly adelgid, an aphid-like insect that invades and kills hemlocks.
In April, a similar foray treated roughly 200 trees in Anchor Diamond Park in the Town of Ballston, Saratoga County. If funding can be found, the Lisha Kill Preserve in Niskayuna may be next and future rounds of treatment are planned for hemlock groves in these and other area preserves, including the Indian Kill Preserve in Glenville.
