Description

Fireblight, a highly destructive disease of several members of the rose family, is caused by the bacterium Erwinia amylovora. This bacterial organism is native to North America and is present throughout the continent where susceptible rose family hosts are grown. In Alberta, this disease can affect many highly desirable hardy ornamentals and fruit-producing species in the rose family including apple, crabapple, cotoneaster, hawthorn, pear, mountain ash, raspberry, saskatoon berry, plum and cherry. It is particularly destructive to species that are not native to Canada such as crabapple, apple and pear.

Description

Over the past two decades, Alberta has developed an excellent reputation for producing high quality, healthy seed potato stocks. Annual losses from bacterial ring rot (BRR) in our commercial potatoes are minimal or non-existent. All seed potatoes in Canada undergo rigorous testing for this highly infectious disease, as required under federal seed regulations. If the disease is found in seed potatoes, current regulations state that all seed lots on that seed farm or farm unit will be decertified in that year.
