Go straight to the website for the Department of Agriculture, Trade and Consumer Protection at http://datcp.wi.gov. Click on the Environment tab and then click on Landscape Pesticide Registry. It's easy to register your own address. Then you can register the addresses of any neighbors who use commercial lawn pesticide application. The lawn company is required to contact you (usually by telephone) and give 24 hours notice that they will apply pesticide. This gives you enough time to protect your garden crops, poultry, pets, bees, and children from the harmful effects of pesticide.
Remember the deadline is quickly approaching. Don't delay. I've found this to be effective and helpful.
