Herbicides vs. Hand-Pulling of Aquatic Plants
In late May Conservation Commission members voted unanimously to approve the DCR’s proposed use of the herbicides Sonar and Diquat to eradicate plants plaguing Field Pond. While several neighbors of Field Pond were pleased with the Commission’s decision, some neighbors and the 12 members of the Friends of Harold Parker State Forest board of directors were opposed to the herbicide treatment.

The head of the Friend’s group, said that while the group’s initial opposition was a general reaction to the use of pesticides in pond, when they were asked to back up their opinions with facts they found a great deal of scientific evidence for why it wasn’t a good idea. Most notably, “we discovered that these chemicals could affect private wells. In fact, the label one of the herbicides said it should not be used within a quarter-mile of any potable water intake.”

They ultimately came to an agreement with the DCR that said they could run a trial experiment from August to early November to attempt to clear the pond of weeds by pulling them by hand. It was agreed that clearing 25 percent of the weeds by November would be a useful indicator of the feasibility of the hand-pulling method.
