Sessions Sponsored by the Forest Pathology Committee at the
2010 APS Annual Meeting

The 2010 APS meeting was held August 7-11, in Nashville, Tennessee.

In addition to the field trip, special session and technical session listed below, there were also many forest pathology posters.

Ornamental & Forestry Nursery Field Trip

Saturday August 7th, 8:00 a.m. - 6:00 p.m. APS Sponsoring Committees: Diseases of Ornamental Plants; Forestry Pathology

The Tennessee ornamental horticulture and forestry industries face unique pathogen challenges. Come see long-standing operations and visit with up-and-coming growers to hear how they’ve grown quality plant materials under foliar and root disease pressure during this difficult economic time. Greenhouse and nursery growers will showcase their operations and talk about their disease management programs and how they are integrating cultural, biological, and chemical controls.


Committee Meeting: Sunday August 8th, 8:30-10:00 a.m.


Special Sessions:

Restoring Forest Ecosystems Impacted by Invasive Pathogens

Tuesday August 10th, 1:00-3:30 p.m., APS Sponsoring Committees: Forest Pathology

Numerous North American forest ecosystems have been severely impacted by nonnative invasive pathogens.  Although the long-term damage that has resulted is recalcitrant to recovery, progress is being made to restore some impacted ecosystems.  Several examples of restorations that are ongoing will be presented.

Can whitebark pine be saved? ELLEN MICHAELS GOHEEN, USDA Forest Service, FHP, R-6, Central Point, OR, U.S.A.
Rescuing Port-Orford cedar. RICHARD SNIEZKO, USDA Forest Service, Cottage Grove, OR, U.S.A.
Restoring a fallen giant – The American chestnut. WILLLIAM L. MACDONALD, West Virginia University, Morgantown, WV, U.S.A.
The future of California and Oregon coastal forests. DAVID RIZZO, University of California–Davis, Davis, CA, U.S.A.


Edible and Medicinal Mushrooms: Diversity, Commercial Production, and Disease Management in High-Volume Production Facilities

Monday August 9th, 8:30-11:30 a.m., APS Sponsoring Committees: Mycology; Forest Pathology and Extension

This special session will provide an overview on the diversity of edible and medicinal mushrooms and on the state-of-the-art in the commercial production of gourmet and specialty fungi, highlighting the economic impact of this emerging agricultural product. Additional emphasis will be on modern disease management strategies employed in large-scale production facilities.


Refining Systematics (Taxonomy, Nomenclature, Phylogenetics) for Better Resolution in the Population Biology and Evolution of the Oomycetes

Tuesday August 10th, 8:30-11:30 a.m., APS Sponsoring Committees: Mycology; Forest Pathology

Although Phytophthora, Pythium, and the downy mildews are among the most studied organisms in systematics, there is still a great deal of confusion in recognizing valid species and new genera. Poorly annotated sequences exist in GenBank, making it impossible to identify some of the clusters for extypes or neotypes and consequently, the proper identity of an isolate. Examples of these complexes include Phytophthora capsici, Phytophthora citricola, Phytophthora drechsleri, Phytophthora megasperma, Pythium irregulare, prov. genus name Phytopythium vexans, and Py. helicoides. Although morphological and molecular characterization is used for describing new species, some have recently been found invalid. Establishing proper nomenclature provides a solid foundation for research tied to the species and for associated regulatory and disease control decisions. Experts in systematics, evolution, and population genetics will participate in this session, hopefully stimulating collaboration for addressing these major challenges in oomycete systematics.
