Presentation Transcript
slide2

The potato was domesticated in the proximity of Lake Titicaca, near the current border between Peru and Bolivia. For nearly 500 years it has crossed continents and oceans, reaching countless new homes and taking root in cultures and communities around the world.

golden nematode globodera rostochiensis
established as a pest species in Newfoundland

Newfoundland potatoes cannot be exported to the mainland

cars are supposed to be washed before being loaded onto ferries

Plants infested with nematodes produce fewer and smaller potatoes

Cysts may survive up to 20 years before hatching

Golden Nematode“Globodera rostochiensis”
why here
common in many parts of Russia, central Europe, eastern Africa, and South America

likes moist summers, relatively mild winters, or where snow cover slows freezing

parts of Newfoundland (Avalon Peninsula); central Saanich Pen., Vancouver Island, BC; Long Island, NY; and central México

Why only in these places?

Why Here?
potatoes to m xico
spread of potatoes to North America depended upon their transport by Europeans

potatoes as a food supply to Méxican port of Veracruz

Golden Nematode was transferred from Basque coast to new breeding area in México

Potatoes to México
potatoes to north america
England obtained potatoes from Spanish sources, from different areas of South America

early 1600s, potatoes, but not the Golden Nematode, introduced to Bermuda, then to Virginia (1613)

potatoes without Golden Nematode arrived by mid-1600s in coastal North America

Basque Potatoes brought by Dutch to Nieuw Amsterdam (now New York)

grown in the suitable soil of Long Island

Golden Nematode had traveled with the Basque potatoes to The Netherlands, and now was established on Long Island

Potatoes to North America
potatoes to maritime canada
not popular with Acadian farmers

France failed to introduce potatoes to colonies

Prince Edward Island ranked last in agricultural potential by French govt. in early 1750s

Brit. Gov. Lawrence introduced potatoes to Halifax & Lunenburg (1760); later to PEI in 1771

predominantly from New England

do not appear to have carried the Golden Nematode with them.

Potatoes to Maritime Canada
potatoes to newfoundland
uncertain exactly when potatoes arrived

perhaps directly from coastal Basque Provinces, or

by Irish, who originally obtained potatoes from Basque Provinces

Basque Provinces have climates suitable for the Golden Nematode

Golden Nematode appears to have arrived with the original importation of potatoes into eastern Newfoundland

remains as a problem for potato growers here

Potatoes to Newfoundland
subsequent movements
Irish Potato Famine in 1847 resulted from importation of blight, Phytophthora infestans, from New York in 1845

1848, blight re-crossed Atlantic to St. John’s

spread of Golden Nematode to Saanich Peninsula, Vancouver Island, BC, in 1965

Subsequent Movements
slide22

In 2005,

the Maritimes,

St. Lawrence Valley,

and western Canada each accounted for approximately equal shares of Canadian Potato production

Current Potato Production

slide24

Relative decline in PEI and NB:

drier summers, overproduction,

low prices,

competition,

blocking of imports by the USA resulting from discovery of PVYN virus in late 1990s

slide25

Potato production is declining in NL

Competition is main factor
