Better Farming – September 2016

Syngenta spent part of the 2016
season promoting Clariva pn, a
biological nematicide seed treatment
intended to help deter and limit the
yield loss caused by SCN. Clariva pn
was launched in Canada in June 2015,
with the active ingredient of pasteuria
nishizawae bacteria. The product is
also registered in the United States.
The promotion included testing
250 soil samples from across south-
western Ontario. “Half those samples
came back positive for SCN,” says
Brenneman. “It was alarming. A lot of
people just aren’t aware of whether or
not they’ve got SCN.”
Brenneman says as SCN continues
to spread farther north and east,
Syngenta breeders are breeding earlier
varieties. “This year we have a 2,600
heat unit soybean that has SCN
protection in it,” he says. “It used to be
3,000 heat units and above. SCN is the
number one yield-limiting factor for
growers in Ontario.”
Soybeans for glyphosate-resistant
weeds
In soybeans, the next big thing has
been kicking around for a while,
waiting on approvals. Effective July 22,
the European Union has authorized
food and feed import of soybean
grain, oil and meal containing the
Roundup Ready 2 Xtend trait stack.
Roundup Ready 2 Xtend soybeans are

glyphosate and dicamba tolerant.
“Glyphosate-resistant weeds are at
the front and centre (of attention)
again, and so is the need for good
solutions to control them,” says Derek
Freitag, regional agronomy lead with
Monsanto Canada for DEKALB brand
seed. “We’re looking forward to
demonstrating Xtend and getting
some growers working with Xtend for
next year.”
Martin Harry, who also sits on the
board of directors of Soy Canada, says
he has heard growers speak enthusias-
tically about the new technology.

With more varieties of weeds acquiring glyphosate resistance, crop
control companies are working on new strategies to control them.
