Roundup resistance not wanted

An Alberta farmer is frustrated no one will take responsibility for his

field becoming contaminated with Roundup tolerant canola when he seeded

a non-Roundup tolerant variety.

Walter Zulyniak said neither Agricore United, the company he bought the

seed from and seeded the crop for him, nor Dow AgroSciences, which

developed the Nexera 705 canola, will accept responsibility for having

Roundup tolerant plants appear in his field where none had been grown

before.

“Do we just stand by and let them contaminate your land and walk away.

Farming Smarter receives financial boost from Alberta government for potato research

Farming Smarter near Lethbridge got a boost to its research equipment, thanks to the Alberta government’s increase in funding for research associations.

There’s got to be some justice,” said Zulyniak of Camrose.

He said he was shocked when hundreds of canola plants in his 115 acre

field didn’t die when it was sprayed with Roundup on June 25. He

estimates from 10 to 30 percent of the crop that germinated had the

Roundup tolerant traits.

Because of the drought, a decision was made to spray the crop with

Roundup to kill it. The crop was sprayed but many plants continued to

thrive.

Zulyniak said he has made a conscious decision not to grow Roundup

resistant varieties of canola on his farm and now he must spend

hundreds of dollars to get rid of the Roundup resistant plants he

avoided.

“I’m not knocking Roundup, but I bought contaminated seed,” said

Zulyniak.

“They know what’s in there yet they’re still selling it to farmers,” he

said.

In an Aug. 2 letter to Zulyniak after a meeting with Dow and AU

officials at the farm, AU’s Derrick Mizera of Camrose wrote: “As stated

in the meeting, there is no real one to blame or hold responsible, all

practiced and regulatory protocols were follow(ed) by Dow AgroSciences

and Agricore United and yourself.”

Zulyniak rejected AU’s offer to pay for one application of Reglone 240

to kill the volunteers that weren’t killed by the Roundup.

In exchange for spraying the field Zulyniak was asked to sign a form

releasing the companies of responsibility and Zulyniak was asked not to

talk about the field.

“No way was I going to accept the offer and keep my mouth shut for

$400,” the amount Zulyniak estimated to be the cost of one Reglone

application.

Lyle Friesen, research associate in the Department of plant science at

the University of Manitoba, said the problem of seed contamination

isn’t unique to Zulyniak.

After farmers started complaining about Roundup resistant canola

volunteers unexpectedly showing up in their fields, Friesen tested 33

seed lots of pedigreed seed for herbicide resistance this spring.

Of the 33 seed lots sampled, only one seed lot had no detectable

contamination. Out of 33 seed lots, 27 had unique tag numbers, meaning

they were drawn from different sources.

“There’s a problem,” said Friesen.

“If you’re like this farmer, you’re not expecting to have this

resistance trait and you spray it with Roundup and you end up with this

mess,” said Friesen, who conducted the research to see how widespread

the cross pollination of herbicide and non-herbicide resistant canola

has become since herbicide tolerant canola was introduced in 1995.

“We wanted to see what’s happening and publicized that farmers will get

more than what they bargained for in these conventional seed lots.”

Fourteen of the seed lots had contamination in excess of 0.25 percent

and therefore failed the 99.75 percent varietal purity guideline for

certified seed. A 0.25 percent contamination would be one wrong seed in

400.

Certified seed must meet certain seed production standards, but there

are no genetic purity standards.

The samples of Nexera 705 seed, the same kind that Zulyniak grew, had

the highest amount of seed contamination in the study, said Friesen.

The two Nexera lots ranged from three to five percent contamination,

equivalent to 12 to 20 wrong seeds per 400. That translates into about

two to four wrong seeds per sq. metre in the field, said Friesen.

Dave Dzisiak, marketing director for Dow AgroSciences Canada, said when

farmers sign an agreement to grow Nexera canola, Dow guarantees the

canola will produce a high profile oil, not that it is free of

herbicide tolerant traits.

“We are very confident when a grower buys our seed that the seed can do

what the grower bought it for, to produce the crop, and get a premium

for it,” said Dzisiak of Calgary.

“What we have to do is ensure, to guarantee, what our canola will do,”

he said.

Nexera canola varieties produce oil with high oleic and low linolenic

levels, giving it a more stable shelf life without hydrogenation.

Growers are often paid a $2 per bushel premium for growing the crop

under contract.

Dzisiak said seed is checked for stray herbicide tolerant traits at the

breeder and foundation stage of the seed multiplication. Any sign of

herbicide tolerance at that stage is removed, but it is virtually

impossible to guarantee the crop doesn’t have herbicide tolerant traits

once it reaches the certified stage.

“If you wanted to guarantee the seed didn’t have something in it you’d

have to test every seed.”

Brian Harrison, production and sales manager with Proven Seeds, said

Zulyniak’s field is an isolated case.

“I don’t think it’s a problem at all,” said Harrison of Winnipeg.

Most farmers across Western Canada have grown some kind of herbicide

tolerant canola and will have herbicide tolerant volunteers appearing

in their field.

Zulyniak said he plans to launch a lawsuit against Agricore United,

which he had the contract with, for selling seed that was contaminated.
