Sessions Sponsored by the Forest Pathology Committee at the

2011 APS-IPPC Joint Meeting

The 2011 APS meeting was held August 6-10, in Honolulu, Hawaii.

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

Tropical Forest Pathology Field Trip

Saturday August 6th, 8:00 a.m. - 6:00 p.m. APS Sponsoring Committees: Forest Pathology; Tropical Plant Pathology; Emerging Diseases and Pathogens

This loop tour of eastern Oahu will feature several tropical forestry diseases. At the Muanawili Research Station, we will see testing of koa clones to Fusarium oxysporum wilt, the rust disease caused by eucalyptus. At the Waimanalo Research station, we will see several tropical tree-crop species and some of the diseases that affect them.

Committee Meeting: Saturday August 6th, 6:30-8:00 p.m.

Special Sessions:

The Developing Crisis, International Movement of Insects and Pathogens in Commercial Trade
Sunday, August 7; 1:00 - 4:00 p.m.
Section: Emerging Pests/Invasive Species
Organizers/Moderators: Thomas Harrington, Iowa State University, Ames, IA, U.S.A.; James Steadman, University of Nebraska, Lincoln, NE, U.S.A.
Sponsoring Committees: APS Forest Pathology; APS Public Policy Board; APS Regulations; APS Office of International Programs; IAPPS
Financial Sponsors: The Nature Conservancy; Pioneer Hi-Bred a Dupont Business
This session brings attention to the growing crisis in the movement of insects and pathogens around the world through commercial trade. As trade grows, so grows the introductions of pests that threaten agriculture and natural resources. In some areas of trade, we need more stringent national and international regulations, but in others, current regulations may pose serious impediments to trade. We begin with a case study of Hawaiian problems with alien species. Potential for unwanted introductions in commercial seed trade will be contrasted with the need for better international standards. There will be presentations on introductions of insects and pathogens in woody packing material and flaws in international protocols for preventing entry and spread of pathogens via “plants for planting”. Efforts to develop better public policies to reduce risks will be discussed.

Tropical Forest Pathology
Wednesday, August 10; 8:30 - 11:30 a.m. 
Section: Plant Pathology-Diseases of Plants
Organizers/Moderators: Pauline Spaine, USDA APHIS, Riverdale, MD, U.S.A.; Jennifer Juzwik, USDA Forest Service, Northern Research Station, St. Paul, MN, U.S.A.
Sponsors: Forest Pathology; Tropical Plant Pathology; Mycology
Sizeable portions of the continents of Africa, Asia, Australia and South America lie within the geographically defined tropics. Wild land or natural forests and managed or plantation forests are highly valued for timber production, watershed protection, wildlife habitat, global warming mitigation, and cultural connections.  Diseases of trees in these settings threaten the health and survival of Acacia, Casaurina and Eucalytptus species, in particular. The biology, epidemiology and development of disease resistance for management will be discussed for major pathogens of these and other taxa.
