Canola Striped Flea Beetle has now been detected at the North Central Research Extension Center sticky traps. This is an indicator that scouting should begin as crops continue to emerge. This should be done regularly until canola reaches the 4th to 6th leaf stage. Most damage is likely to occur during the first two weeks following crop emergence. For foliar insecticide applications, the action threshold arrives when 20-25% defoliation has occurred to plants younger than the 4th leaf stage. For more information on the Canola Flea Beetle, please refer to the NDSU Extension “Integrated Pest Management of Flea Beetles in Canola” publication (E1234).
The USDA National Ag Statistics Service issued its Annual Prospective Plantings Report on March 29 and it shows that North Dakota canola acres are expected to be 1.65 million acres this year. This is up 90,000 acres from last year’s planted acreage and up 190,000 acres from 2016.
Producers intend to plant 2.08 million acres in the U.S. in 2018, down just 1,000 acres from last year’s record high planted area. Compared with last year, planted area is expected to increase in 4 of the major canola-producing States, with acreage in Idaho expected to nearly double from 2017. If realized, planted area in Idaho, North Dakota, and Washington will be record highs.
The U.S. Canola Association cautions consumers about the misinterpretation of results in the study, “Effect of canola oil consumption on memory, synapse and neuropathology in the triple transgenic mouse model of Alzheimer’s disease,” by Elisabetta Lauretti and Dominico Pratico at Temple University. It was published Dec. 7 in Scientific Reports – an online, open access journal.
The study was conducted using a mouse model; it was not a human clinical trial. Specifically, mice were genetically engineered to develop three characteristics of Alzheimer’s disease (AD): memory impairment, amyloid plaques and neurofibrillary tangles.
“This mouse model is a huge stretch from what you may see in humans,” says Peter J. Jones, Ph.D., Canada research chair in functional foods and nutrition, Richardson Center for Functional Foods and Nutraceuticals, University of Manitoba.
“Animal models of Alzheimer’s lack predictive validity,” adds Richard Bazinet, Ph.D., associate professor at the University of Toronto’s Department of Nutritional Science, who reviewed the study. “We have a series of major phase III clinical trials in Alzheimer’s disease. The drugs ‘worked’ in the animal models, but failed in humans.”
The researchers divided the mice into two groups at six months of age before they developed signs of AD. Twelve mice were fed a normal diet, while the other 10 mice were fed a diet supplemented with canola oil. The researchers then assessed the mice at 12 months, noting the canola oil-fed mice gained weight compared to those fed the control diet. This finding is not surprising given that the canola oil diet was higher in calories than the control diet.
“The two diets were not balanced for fat content,” explains Jones. “We know that higher fat diets are more palatable and lead to increased food intake and weight gain, which is what happened here. This weight gain would have happened with any type of fat being provided. Animals with greater body fat will elicit reduced food-seeking behavior which may, independent of any fat-induced action, well explain the differences in brain chemistry and memory.”
Some news reports about the study compare the results of canola oil to olive oil. The same researchers published a similar study in Annals of Clinical Translational Neurology in June 2017 using mice fed either a standard diet or one supplemented with olive oil. The current study does not include an olive oil group. Therefore, comparisons between canola and olive oils are limited except that they are both predominantly composed of monounsaturated fat. In addition, the mice fed olive oil in the first study also gained more weight than the control group.
“The contrast in the study of canola oil with olive oil is completely inappropriate without a group fed olive oil being tested,” says Jones. “This is an absurd over-reach of what the data provide without testing both oils side by side.”
The studies comparing olive oil and canola oil to a standard mice diet were reviewed by Health News Review, a team of independent health reviewers who apply standardized criteria to news stories. Their two reviews, “Here’s Why You Can go Ahead and Ignore all Those Clickbaiting ‘Olive Oil Protects Against Alzheimer’s Headlines” and “Temple University Again Greases the Clickbait Machine with Canola Oil Study,” found numerous flaws in both studies. This time, the researchers used “a similarly shaky study using the same methodology to claim canola oil could be bad for the brain,” wrote the reviewer.
“Temple [University] issued this attention-grabbing news release: Canola oil linked to worsened memory & learning ability in Alzheimer’s. Once again, the headline jumps way ahead of what the research actually shows … This new study doesn’t say anything meaningful for consumers.”
Moreover, an independent scientist at the University of Florida, Kevin Folta, Ph.D., critiqued the canola oil study as well in his article “No Evidence of Canola Oil Causing Alzheimer’s and Dementia,” concluding that “the paper does not show in any way that there is a causal link to disease in humans. Not even close.”
Out of six measures and three different tests, the canola oil-fed mice were different for one test and showed about a 20 percent difference in behavior, notes Folta. The researchers refer to this as “significant deficits of working memory” but this slight difference in one test is inconsistent with this claim.
The notion that canola oil is linked to dementia and worsens Alzheimer’s symptoms “in no way reflects what the data present,” Folta continues. “What the data show is that mice fed more calories from oil that get overweight behave slightly differently in one of several neurological tests and has a subset of biochemical changes that are consistent with AD, in a mouse that is designed to have neurological modifications that are consistent with AD … these results do not indicate any ill effect on human health, and show slight effects on messed up mice.”
Finally, contrary to Pratico’s claim that “very few studies have examined the claim that canola oil is healthy,” there is substantial evidence based on human clinical trials attesting to this fact, especially canola oil’s ability to help reduce the risk of heart disease. In fact, clinical studies have been going on for decades involving thousands of human volunteers to examine canola oil and its effects on the body. A scientific literature review published in the peer-reviewed journal Nutrition Reviews in May 2013, summarizes 40 research studies to date related to the health benefits of canola oil.
In 2006, the U.S. Food and Drug Administration authorized a qualified health claim about canola oil’s ability to reduce the risk of heart disease when used in place of saturated fat.

The first U.S. canola production forecast for 2017 is 2.81 billion pounds, down 9 percent from the revised 2016 production of 3.09 billion pounds. If realized, this will be the third largest production on record for the United States. Area planted, at a record high 2.08 million acres, is down 4 percent from the June estimate but up 21 percent from last year. Canola farmers expect to harvest a record high 2.03 million acres, down 4 percent from June but up 20 percent from 2016. The October yield forecast, at 1,383 pounds per acre, is 441 pounds below last year’s record high yield and will be the lowest since 2007, if realized.
The yield in North Dakota, the largest canola-producing State, is forecast at 1,410 pounds per acre, down 430 pounds from last year’s yield. Planted area in North Dakota is estimated at 1.59 million acres, an increase of 9 percent from 2016. Planting of the canola crop in North Dakota was generally behind last year’s pace, but ahead of the 5-year average. Maturation of the crop followed that same pattern for the majority of the growing season and harvest was underway by early August. Harvest progress reached 95 percent complete by September 24, two percentage points ahead of last year and 4 percentage points ahead of the 5-year average.
Clubroot Alert from Cavalier County Agent Anitha Chirumamilla:
Be vigilant while swathing and let me know if you suspect any low yielding spots. Dr. Venkat Chapara at the Langdon Research Center is working on a survey to see the distribution and spreading patterns of this disease. Prevention and early detection play a key role in the management of this disease. We can be ahead of this disease by being proactive
Dicamba survey still open; options being evaluated: The North Dakota Department of Agriculture (NDDA) has been gathering information on plant injury that may have been caused by use of the herbicide dicamba.
Growers and applicators who suspect dicamba injury are encouraged to complete a survey on NDDA’s website to help quantify the number of potential reports and acres impacted.
“We’ve had a lot of responses on the dicamba survey,” Agriculture Commissioner Doug Goehring said. “The 2017 spraying season has wrapped up, but the information we’re gathering will help determine restrictions and protocols for the 2018 growing season.”
Dicamba is a selective herbicide used to control broadleaf weeds and woody plants. It has many applications, including lawn care, crop production and range management. Historically, it has been used in pre-plant applications on soybeans. Recently, new low-volatile formulations have been approved for postemergence use on dicamba-tolerant soybeans.
“I’ve been in talks with Monsanto, BASF and DuPont and they are willing to send representatives out to look at fields that may have been affected,” Goehring said. “Producers who would like to speak to a company representative should contact their local chemical dealers.”
Goehring is considering changing application protocols for dicamba to protect non-target crops. Producers are encouraged to provide specific feedback on the survey.
The survey may be found at www.nd.gov/ndda/dicamba-survey.
Information gathered from the survey will not be used for pesticide enforcement against applicators and no penalties will be issued based on the survey. Those wishing to file a formal pesticide complaint should contact NDDA 701-328-2231.
The new generation of crucifer flea beetles is emerging, and feeds on the green foliage and developing pods. Field reports of significant feeding injury have been observed near Napoleon in south central ND. Usually the upper or younger pods and later seeded crops are most impacted. This feeding damage results in poor seed fill, premature pod drying, shriveled seeds, or pod shattering, and provides an entry point for fungal growth within pods in damp weather. However, it is usually not economic since most of the yield comes from the lower pods. If canola is under drought stress, damage could be more severe. There is no established threshold for managing flea beetles this late in crop development. If you are considering spraying an insecticide, it is important to observe the different Pre-Harvest Intervals (PHI) of the insecticides registered in canola. Any pyrethroid insecticide will offer good control of flea beetles and residual activity until harvest. Examples of active ingredients and PHI include: bifenthrin – 35 days PHI (Sniper, Tundra EC, Brigade 2EC, others); deltamethrin – 7 days PHI (Delta Gold); gamma-cyhalothrin – 7 days PHI (Declare); lambda-cyhalothrin – 7 days PHI (Grizzly Too, Silencer, Warrior II, others) and zeta-cypermethrin – 7 days PHI (Mustang Maxx).
