The Town is responsible for maintaining nearly 600 acres of parks and open space property, with approximately 170 acres of that total comprised of turf grass. The Town follows a comprehensive maintenance plan for all Town property, and this includes implementing a Weed and Pest Management Program based on carefully controlled and monitored best practices. In conjunction with cultural, mechanical and biological controls, the Town uses chemical controls when necessary. This program calls for posting notice of applications at least a day prior, and the information is also placed in the schedule link above. The Town monitors the best practices throughout the region for weed and pest management and reviews this program annually.

Weed and Pest Management Program
The Town uses an Integrated Pest Management (IPM) approach based on best practices to control weeds and pests on all parks and open space areas. This approach is well-researched and established as an effective and environmentally sensitive approach to weed and pest management based on a foundation of several broad elements. Prominent IPM program components include applying common-sense practices; utilizing a combination of cultural, biological, and chemical measures that emphasize the least-toxic approach to controls; economic feasibility; and a strong emphasis on minimizing the use of chemical control measures.
The four basic steps of the Town’s IPM program:
- Set action thresholds. Before any control action, Town staff determines if the amount of weeds or pests present in an area requires a response.
- Monitor and identify pests. Not all weeds or insects require immediate control actions.
- Prevention. Measures include improving soil health by aeration and adding soil amendments, mulching trees, and aerating. Well-maintained facilities and healthy plant material are less susceptible to weeds and pests.
- Control. Effective, less-risky methods are implemented first, such as mowing weeds before going to seed, releasing Canada thistle gall mites, or hand-pulling small areas. EPA-approved synthetic herbicides and pesticides are applied to targeted areas when determined to be necessary; and this is done at the lowest application rate possible by State-licensed and certified applicators.
When determined to be the most appropriate control measure as part of the Town’s overall IPM program, the Town will use chemical controls for broadleaf weeds in landscape turf, noxious weeds in open space areas, weeds on soft-surface trails; mosquitoes; algae and duckweed in ponds; and ash borers and IPS engraver bark beetles in spruce and pine trees.
Weed and pest control occurs in varying degrees, applying the measures according to the Town’s IPM approach. When chemical application is deemed necessary for weed control, a commercial product similar to RoundUp known as Prosecutor (glyphosate) is used along with Lesco 3-Way (2,4-D). Aquabac (Bti) and Aqualuer 20-20 (permethrin) are used for mosquito control. Sonar (fluridone) and Diquat are used for pond water quality. Permethrin is the tree pest control. MSDS sheets are linked to each of the different controls listed in this paragraph
