Scientists unswayed by Monsanto findings on rogue wheat

Several plant scientists questioned conclusions Monsanto Co. (MON) drew from its investigation of an escaped gene-altered wheat variety and said there is still a risk that rogue grain is in the seed supply.

In its first detailed response to last week’s announcement that a genetically modified wheat not approved for use was found growing in an Oregon farmer’s field, Monsanto said that it has since tested 31,200 seed samples in Oregon and Washington and found no evidence of contamination.

Genetically modified wheat: Discovery in Oregon field re-ignites a scientific dispute

Stunned researchers at Oregon State University couldn't help but question themselves. Once, twice, three times in early May -- in two different labs -- they analyzed DNA extracted from wheat plants grown on an eastern Oregon farm.

A farmer's attempt to kill the plants with weedkiller had failed, and a growing cadre of university and state agriculture officials wanted to know why. With each test, the result was the same: The wheat had been genetically modified to resist glyphosate, the key ingredient in the herbicide Roundup.

GMO Wheat Found In Oregon Field. How Did It Get There?

About a month ago, a farmer in eastern Oregon noticed some wheat plants growing where he didn't expect them, and they didn't die when he sprayed them with Roundup.

The farmer sent samples of these curious plants to Carol Mallory-Smith, a scientist at Oregon State University who has investigated other cases in which genetically engineered crops spread beyond their approved boundaries.

Proclamation can't replace state funding for weed control

Gov. John Kitzhaber has declared May 19-25 Invasive Weed Awareness Week, and, according to the Oregon Department of Agriculture, the state needs to be diligent in its war against weeds.

But you wouldn't know it by the department's proposed 2013-15 budget.

Under a directive to cut $1.2 million in lottery funding, the department has proposed cutting $518,896 from its weed program, or about 25 percent of its state funding.

Roughstalk bluegrass emerges as problem in grass seed fields

Two consecutive rainy springs are being cited as the primary reason for an influx of roughstalk bluegrass in Willamette Valley grass seed.

With the industry's top control option all but eliminated, growers are finding it difficult to keep the weed in control and keep stands viable.

In some cases, growers will be wise to pull out stands earlier than planned, according to Andy Hulting, Oregon State University College of Agricultural Sciences weed control specialist.

"Particularly, some of the tall fescue fields are going to have to come out, because we don't have the tools to manage it in those fields," Hulting said.
