The Greater Madison Healthy Lawn Team (GMHLT) is a group of citizens in the Madison, Wisconsin area who are concerned with the health and environmental effects of pesticide and fertilizer use in our community. (Pesticide is the umbrella term for herbicides, insecticides, and fungicides - chemicals designed to kill insects, weeds, and molds.)

We realize that many people want to be good neighbors when it comes to lawn care. Some folks would like to have a "perfect" yard for their neighbors, to avoid the spread of weed seeds across property lines, hoping that their neighbors would do the same. However, the idea of a "good neighbor" is changing as we realize that these chemicals can become airborne and be inhaled, can be tracked into other's yards and homes, and are flushed into local watersheds and lakes.
