1. This project, led by Dan Herms, continues to develop with another year of data from Wooster and the Lake County nursery area, and the extrapolation of the phenology information to the rest of Ohio for the timing of insect and mite management practices.
2. Check out the latest phenology calendar information on the following website: http://www.oardc.ohio-state.edu/gdd/
3. The newest component of this project, coordinated by Denise Ellsworth and Dan Herms, is the planning for Phenology Gardens throughout Ohio, from Lake County nurseries to OSU Extension Piketon Center, from the OSU Extension Clark County trial gardens to the OARDC's Secrest Arboretum in Wooster.
4. Phenology and growing degree day information was included as a regular portion of the Buckeye Yard and Garden Line (BYGL) weekly electronic newsletter during the growing season of 2003.
1. Images of herbaceous landscape annual and perennial diseases, insects, and mites were taken by ENLTTers throughout the 2003 season as part of their survey for these diseases and pests. Nodes of this project were in northeast Ohio, central Ohio, southwest Ohio, and west central Ohio.
2. These images are now being catalogued and with one more year's work will be used for a publication of Diseases and Insects of Herbaceous Annuals and Perennials to be published by the Ohio Nursery and Landscape Association (ONLA) as part of the ENLTT's partnership with ONLA. A CD will also be developed with this information. Publication with nationwide distribution is anticipated by the end of 2004.
3. This project has already yielded raw materials (slides and Power Point presentations) for several perennial disease programs for the green industry and general public around Ohio, including several in Geauga County, in Lucas County, and in Clark County.
1. Biweekly Nursery/Landscape IPM programs are conducted by Randy Zondag and Dan Herms with growers and other green industry professionals, discussing phenology, pest management, monitoring, pesticide application technology, and diagnostic topics.
2. This project is linked to the United States Department of Agriculture and Charles Krause's USDA-ARS pesticide Application Technology Research Unit which is involved in finding the most efficient ways to apply pesticides by improving coverage and reducing non-target application. This project also involves linking IPM strategies to improved environmental monitoring. See the following websites developed for such monitoring.

3. For more on the USDA connections to the ENLTT project, see articles in the OARDC/OSUE Ornamental Circular for 2003, to be published in January, 2004.
1. Emerald Ash Borer (EAB). IPM perspectives on EAB are included in articles in the 2003 Ornamental Circular, throughout the season in the BYGL, in the special December 2003 Emerald Ash Borer special edition of the BYGL, and numerous programs including EAB information for arborists, landscapers, diagnosticians, and the general public. Dan Herms also led several ENLTT-sponsored EAB tours for team members, for the green industry and for public officials and is heavily involved in statewide, regional, and national EAB research and management initiatives.
2. Disease surveys of Phytophthora ramorum (none found) and pathogenicity studies of honeylocust knot disease were conducted in 2003 by Enrico Bonello.
3. A Riker mount project for insects and diseases of ornamental plants for Extension programming was started in 2003 by the OSU C.Wayne Ellett Plant and Pest Diagnostic Clinic as part of ENLTT's 2003 IPM Project.
