Controlling
Little Cherry Disease
In the 1930’s, biologists
raced to find a solution to the
virus that was devastating Kootenay
Lake cherry orchards. In 1938,
they successfully introduced a
parasitic wasp that dramatically
reduced the population of virus-carrying
apple mealybugs. In the following
decades, an ongoing control program
resulted in the identification
and removal of diseased trees
in an effort to prevent the spread
of little cherry disease to the
Okanagan region. In the Regional
District of Central Kootenay,
a 1982 bylaw that enforced the
removal of diseased trees has
resulted in the revival of the
area’s cherry growing industry.

The Golden Age of Kootenay
Orchards
Prize-winning apples, cherries as big as
plums – in the early 1900’s,
Kootenay Lake was a major fruit-producing
area, rivaling the Okanagan to the west
as a lucrative land of orchards and berry
patches.
As the Kootenay mining industry waned in
the early years of the 20th century, the
Canadian Pacific Railway began to promote
the area as a fruit-growing oasis. English
settlers responded to the CPR’s campaign,
planting apple and cherry trees, and establishing
thriving strawberry fields. Kootenay fruit
was soon recognized as some of the finest
in the world, taking prizes at prestigious
international competitions. Crate after
crate of rosy apples were loaded on to the
steamships that connected the Lake’s
shoreline communities, bound for export
around the world, and supplying their growers
with healthy, dependable profits.
Little Cherries,
Big Problem: The giant,
juicy cherries of Kootenay Lake were the
greatest source of pride for the area’s
orchard-growers. (In the fruit-growing town
of Kaslo, on the Lakes’ western shore,
cherry trees symbolically lined the community’s
downtown boulevards.) But sadly, the cherries
were also the cause of their economic demise.
In 1933, a devastating virus known as “little
cherry disease” began to spread through
the Kootenay cherry orchards. Transmitted
by the apple mealybug, the disease caused
the cherry trees to produce small fruit
with pale colour and poor flavour.
The disease, which began at Willow Point,
eventually affected every orchard in the
Kootenay region, and by the 1950’s
the Kootenay cherry industry had been decimated.
(By 1979, the region’s cherry production
had dropped from 680,000 kilograms in 1947,
to 68,000 kilograms, most of which did not
meet packinghouse standards.)
With the advent of World War II, Kootenay
orchard-growers suffered another blow. Demand
for “luxury” fruits such as
apples declined dramatically. In addition,
the growers faced increasing and overwhelming
competition from well-located American growers
to the south. Fruit-growing in the Kootenay
area was no longer a commercially viable
industry.
Today, successful eradication of
little cherry disease has resulted in a
resurgence of cherry growing in the Creston
Valley at the south end of Kootenay Lake.
The Creston Valley has reclaimed its place
as British Columbia’s second most
productive fruit-growing area (after the
Okanagan region to the west). It is known
for its apple orchards, its many roadside
fruit and vegetable stands, and its thriving
“pick your own” industry.
