The University of Idaho (UI) oilseed research group has a long history of agronomic research. It started developing canola cultivars before the crop was approved as Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Association in 1985. Read More »

Plant breeding has driven the development of canola as an edible oilseed crop. In the 1960s, Canadian breeders took an industrial oilseed crop called rapeseed and selected for an edible oil profile, significantly reducing erucic acid to create “Canadian oil low acid” (canola) with excellent edible oil quality. But they were not done. Further advancements were made to change the crop into high yielding hybrids and the use of biotechnology (integrating foreign DNA) added resistance to herbicides, allowing for better weed control and crop management.

It’s now been 24 years since herbicide-tolerant canola was first approved in the United States. The ability to control weeds in canola with post-emergence broadleaf herbicides revolutionized canola production. Prior to 1998, soil-applied herbicides Treflan® and Sonalan® were able to provide decent control for many weeds; however, many canola fields struggled to compete with tough weeds like kochia. With no post-emergence herbicide options other than Stinger®, growers had to save canola for their cleanest fields and hope the crop would outcompete the weeds. Read More »

Producers traditionally have swathed rather than straight-combined canola. In recent years, the availability of new pod shatter-resistant varieties has made straight cutting the new trend for canola harvesting. However, both swathing and straight combining have their places based on harvest conditions. Timely straight cutting can save time and money and result in improved canola yields and seed quality (lower harvest moisture, less green seed and higher test weight). Heavier canola stands are better suited for straight combining than thinner stands because of the decreased likelihood of shattering from wind. In the absence of pod shatter tolerance, straight combining has resulted in yield losses of 8 to 54 percent, as reported by the Canola Production Center in Canada. Read More »

Clubroot disease on canola is caused by Plasmodiophora brassicae, a soil-borne pathogen that moves from field to field on both agricultural and non-agricultural equipment. In simple words, it moves from whatever moves the soil. With an objective to determine the extent of disease spread in North Dakota, clubroot incidence and prevalence has been monitored in annual surveys for six years by examining canola roots for clubs/galls. These surveys have been funded by the Northern Canola Growers Association, Northern Canola Research Program (USDA/NIFA), SBARE and NDCP Product Harmonization Board. Read More »

The Willamette Valley in Oregon encompasses a 150-mile long stretch that runs the lengths of Interstate Highway 5 from Portland to Eugene and east to west from the Cascade Range to the Oregon Coast Range. With numerous waterways and highly fertile soil, this valley is the most agriculturally productive and diversified region of the state. It produces everything from fresh market produce and specialty vegetable seeds to grass and tree seedlings, wine grapes and hazelnuts. Oregon produces over 170 crops statewide and the vast majority of them can be found in the Willamette Valley. Read More »

Consumer trends in recent years have resulted in retails sales of organic foods in the United States reaching $50 billion in 2020, according to the Organic Trade Association. Despite cooking oils derived from multiple crops, including canola, representing a tiny fraction of these sales, consumer interest in organic canola oil has encouraged the food industry to source organically produced canola from farmers.

I farm in the very northwest corner of Minnesota with my brother and nephew. We have grown canola since 1994 and gained many benefits from this very interesting and beautiful crop. Read More »

Crop options are limited in the wheat-dominated dryland areas of the inland Pacific Northwest (PNW) and few rotation crops return a profit similar to winter wheat. However, canola is adapted to the PNW and both spring and winter canola can be grown profitably in the region. Canola adds several benefits in rotation with cereal crops, including reduced plant disease, additional weed control and management options, and in the case of winter canola, increased water infiltration. As a result, a multistate project in Idaho, Washington, Oregon and Montana is being funded by a grant from the National Institute of Food and Agriculture. The goals are to develop regionally adapted canola cultivars and advance agronomic practices to optimize canola performance, thereby increasing regional canola acreage.
