A BEE-BORNE BENEFICIAL
Vectorite product uses pollinators for delivery
By Stephen Kloosterman
Associate Editor
A new product with a new way of
delivering it was recently approved by
the EPA.
Bee Vectoring Technologies
(BVT) recently received approval
for Vectorite with CR-7, which
uses Clononstachys rosea for use
as a fungicide on a variety of crops
including strawberries, tomatoes,
blueberries, sunflowers and almonds.
And there's the added benefit of
not having to hitch up the sprayer.
Bumblebees or honeybees can deliver
it to blossoms all over the grower's
farm operation.
How it works
BVT's CR-7 is an organic product,
listed with the Organic Materials
Review Institute. Clonostachys rosea
is a beneficial fungus that essentially
inoculates the blossoms by using up
resources used by crop-damaging fungi.
That active ingredient is the
brainchild of John Sutton, who spent
decades at Ontario's University of
Guelph isolating 1,300 different strains
of the fungus before selecting the
ones now used in BVT's proprietary
products, said BVT product manager
Ian Collinson. Sutton remains active in
the company today.
" Once he found Clonostachys, and
found that it was suppressing these
diseases, he said, 'wouldn't it be great
if a bee could deliver it to the plant,
because it's going right to where it needs
to go? " Collinson said. Many of the
fungi, including gray mold, botrytis and
Bumblebees crawl through a Vectorpak
in order to pick up Vectorite dust with a
beneficial product that it will distribute later
to plant flowers. Photos: Ian Collinson
mummy berry enter the fruit through
the blossom. Sutton began collaborating
with University of Guelph colleague
Peter Kevan, an expert in bees. The
two approached the leader of a plastics
company about designing some
materials, and the resulting company
went public in August 2015.
Busy bees
BVT's patent-pending technology
has bees pick up Vectorite, a mixture
containing CR-7, from a tray at the hive.

+ The various Rp genes confer resistance to some but not all races of common rust. The effectiveness of a specific Rp gene or
combination of Rp genes in sweet corn will be determined by the common rust races which are prevalent in each growing area.
Degrees Brix may vary depending upon many factors, including agronomic, environmental and analytical methods and conditions.
Performance may vary, from location to location and from year to year, as local growing, soil and weather conditions may vary.
Growers should evaluate data from multiple locations and years whenever possible and should consider the impacts of these
conditions on the grower's fields.
