Pesticide labels are frequently reviewed and changed for many reasons, including host additions or deletions, rate changes, application method changes, and environmental and human safety issues. It is difficult for home growers, as well as commercial producers, to keep up with these changes. In the previous issue of this newsletter, you were given a link to the addendum for the 2001 Commercial Landscape and Turfgrass Pest Management Handbook http://www.ag.uiuc.edu/cespubs/hyg/welcome.html. In that addendum, Bruce Paulsrud listed new fungicides registered for use on turf and ornamental plants.
Another very good source of information is the Illinois Pesticide Review Newsletter, available free on the Internet at http://www.pesticidesafety.uiuc.edu/newsletter/html/index.html. You can print it out at your local Extension office (or elsewhere). In the most recent issues of that newsletter, you can find information on pending label changes for the following fungicides: Aspire, Bayleton, Bordeaux Mixture, Botran, Cuprofix Disperse, Eagle, Flint, Fore, Gravel, Heritage, Kaligreen/Armicarb, Kocide, Maneb, Mefenoxam 2, Phyton 27, Stature, and Taegro. In many cases, new hosts have been added to the label. In a few cases, uses have been removed. Refer to the Illinois Pesticide Review for details; and always read product labels carefully for changes before using the product.
