4 Ponds To Be Treated For Invasive Weed


Several public ponds will be treated for an invasive aquatic weed, hydrilla.

The Department of Natural Resources said it will use Sonar, an herbicide containing fluridone, to treat Millsboro Pond, Wagamons Pond in Milton and Tub Mill Pond and Abbotts Mill Pond near Milford. Sonar is registered and approved for use by the U.S. Environmental Protection Agency and has been used in Delaware since the 1980s. According to DNREC, it does not pose a threat to wildlife, including fish.

Treatment is scheduled to begin this week.

Hydrilla is believed to have entered the state through the aquarium trade. Left untreated, it could crowd out other beneficial plant species and possibly prevent access for fishing and boating.

DNREC said water from these ponds should not be used for irrigation for 30 days after treatment. There are no restrictions on fishing or eating of fish from these ponds.

Residents and farmers along and directly downstream from treated ponds should not use the water to irrigate their gardens, yards or agricultural lands to avoid possible damage to their plantings. Also, anglers and boaters are encouraged to remove all hydrilla and other aquatic plants from their boats, trailers and gear before leaving boat ramp areas.
