EPA's lawn and garden page has resources valuable for teaching consumer pesticide safety and environmentally-friendly pest management methods. This includes a series of videos on effective lawn care methods. Some show master gardeners helping consumers - obviously EPA was sensitive to the Extension partnership we enjoy with the federal agency and it state lead agencies in developing this content.
