Illinois Invasive Plant Posters
New Illinois Invasive Plant publications are available from the University of Illinois, Illinois Natural History Survey, USDA-APHIS-PPQ, and the River to River Cooperative Weed Management Area. There are five posters in the collection. The large poster is 17” by 38” highlighting the four major habitats of Illinois (grassland, woodland, wetland, agriculture) and the top four invasive plants in those habitats. In addition, there are four smaller (8.5” by 11”) posters corresponding to the four habitats on the large poster. Each small poster showcases 8 to 12 plants with a photo and distribution in Illinois on the front and information on identification and why the plant is considered invasive on the back. These publications are free of charge. If you would like copies of the publications, please contact Dawn Refsell at drefsell@illinois.edu with your name, shipping address and the quantity and titles you are requesting 

Abnormal Corn Ears Poster (ACE-1) and Webpage
Peter Thomison and Allen Geyer, The Ohio State University
http://agcrops.osu.edu/corn/documents/AbnormalCornEarsPoster.pdf
Do you know what these look like? Blunt ears (“beer can ears”), “silk balling”, hail damaged ears, crazy top, smut, and barrenness. To help growers sort out various ear disorders and their possible causes, we’ve prepared a poster “Abnormal Corn Ears” and an accompanying web page “Troubleshooting Abnormal Corn Ears and Related Disorders”. In the poster, ten abnormal corn ears with distinct symptoms and causes are highlighted.

The webpage, “Troubleshooting Abnormal Corn Ears and Related Disorders” at http://agcrops.osu.edu/corn/EarAbnormalities.php provides more detailed diagnostic information on various corn ear disorders.

The poster can be downloaded in one-page form from the website or you can order a 26 x 33 inch poster for $10 plus shipping from: The Ohio State University, Communications and Technology, Media Distribution, 216 Kottman Hall, 2021 Coffey Road, Columbus, OH 43210-1044  E-mail: pubs@ag.osu.edu Phone 614-292-1607 Fax 614-292-1248
