Montgomery Parks Integrated Pest Management Program and Pesticide Use
Montgomery Parks manages more than 37,000 acres of parkland including 424 parks, 276 playgrounds, 342 athletic fields and many other amenities. The Department follows Integrated Pest Management (IPM) principles to steward resources and protect them from pests (weeds, insects, animals and diseases) that may harm people or plants, impair function, and deteriorate infrastructure. IPM means managing pests by combining multiple strategies and techniques such as mechanical removal of pests, cultural methods to improve soil and plant health, conserving and introducing beneficial biological controls, and using pesticides.
The Parks Department does not use pesticides for cosmetic purposes. Pesticides are used as a last resort to control noxious and invasive pests, maintain safe and playable athletic fields and courts, and prevent significant economic damage, including degradation of park infrastructure.
Staff who apply pesticides and fertilizers are certified and registered with the Maryland Department of Agriculture. Montgomery Parks is committed to balancing the demand for recreation while protecting and conserving our valuable natural and cultural resources to meet the needs of current and future generations.
What is Montgomery County Code 33B?
County Code Chapter 33B went into effect July 1, 2016. The code presents guidelines for pesticide use in Montgomery County, including on county property and parkland. The goal of the code “is to inform the public about pesticide applications and minimize the use of pesticides for cosmetic purposes, while not restricting the ability to use pesticides in agriculture, for the protection of public health, or for other public benefit.” Learn more about Montgomery County’s pesticide law.
What is Montgomery Parks doing to comply with the law?
Montgomery Parks continues to implement IPM strategies to ensure pesticides are used as a last resort. Montgomery Parks manages all playgrounds, community gardens and common lawn areas within local parks without the use of pesticides. In 2016, Montgomery Parks designated ten pesticide-free parks. In September 2019, the program expanded to 45 pesticide-free parks. Pests in parks designated pesticide-free are managed using alternative methods, such as hot foam, string trimming, mechanical weed removal and products approved for use by Montgomery County Code 33B. The Montgomery County Department of Environmental Protection has examples of products allowed in pesticide-free parks under the law.
