I guess nightshade doesn't get frost bite

The sight of nightshade's purplish/black berries in a "food grade" soybean crop is every producer's worst nightmare. They stain the seed and dramatically reduce the value of the crop. In theory, you would kill uncontrolled nightshade prior to harvest with either a herbicide (i.e. Reglone, glyphosate) or mother nature (i.e. a frost), the berries would drop to the ground, never go through the combine and the seed would be left unstained. Unfortunately this is a theory, and reality shows us otherwise. Around the 12th of October, a significant frost was observed in Waterloo/Wellington county which resullted in a number of annual weed species "dying off" in soybeans.

The one notable exception was nightshade. Even though the leaves were finally starting to wilt after 4-5 days of consecutive frosty mornings, the berries were still very much attached to the plant. Plant dessication with herbicides has proven equally ineffective as many berries will still cling to the plant even after it has died off. The average plant in this field had 280 berries with each berry averaging 60 seeds for a total of 16,800 seeds per plant.

If you had Eastern Black Nightshade in a field of "food grade" soybeans it's either because: 1) You didn't know it was there in the first place or 2) You knew it was there, but the herbicide was ineffective Public trials conducted by the University of Guelph (Sikkema, Swanton and Tardif) have shown that following herbicide programs provide greater than 80% control of Eastern Black Nightshade in soybean. 1) Pursuit (PRE or POST - 99% visual control) 2) Lorox L (PRE - 99% visual control at the highest labeled rate) 3) Dual II Magnum (PRE) followed by Reflex (POST - 98% visual control) 4) Dual II Magnum (PRE, highest labeled rate - 87% visual control) 5) Frontier (PRE, highest labeled rate - 80% visual control) If you have used one of the above herbicide treatments and they did not provide adequate control, it may be possible that the population of Eastern Black Nightshade in your field is resistant. The University of Guelph can test this population for you to determine if it is herbicide resistant.

Nightshade in some corn samples today at the elevator. My dad's field had it bad in a spot where the corn was thin and short. I think this weed needs an attitude adjustment next year!

Thanks Joe, you're absolutely right. There has been limited experience in Ontario with Valtera on nightshade, but so far it has done a very nice job.

Hi Mike: The Valent company has a new product registered for nightshade as well.
Here is their news release on registration.


Valent Canada adds Valtera™ Herbicide to 2009 product lineup
Brand new active ingredient benefits soybean growers

GUELPH, ON —Valent Canada has received Health Canada’s Pest Management Regulatory Agency approval to register Valtera Herbicide for use in soybeans. Valtera is a low use rate preemergence herbicide which gives growers residual control of many broadleaf weeds and enhanced post emergence weed control when tank mixed with glyphosate. It has been sold in the U.S. since 2001 under the trade name Valor® Herbicide.

Valtera controls annual nightshade species (Eastern black nightshade and hairy nightshade), pigweeds (redroot and green), common ragweed, common lambsquarters, and dandelion. Valtera also provides suppression of green foxtail.

New active ingredient
Valtera contains the active ingredient flumioxazin, a member of the protox inhibitor type of herbicides (Group 14), and offers new management options for weeds resistant to Group 2 & 5 herbicides. However, unlike many other Group 14 herbicides, flumioxazin provides enhanced burndown and residual control.

Flumioxazin works by inhibiting production of an enzyme important in the synthesis of chlorophyll. "Its rapid soil and water dissipation," said Regina Rieckenberg, Valent Canada sales and marketing manager, "along with a low use rate, results in a low carryover potential to rotational crops."

In identity preserved soybeans, Valtera is intended to be used in a program with other residual herbicides. It should be applied as a preplant or early preemergence herbicide, from 30 days prior to planting and up to three days after planting (before emergence). In burndown situations, it can be used as a foundation herbicide partner with glyphosate in glyphosate-tolerant soybeans.

"By using flumioxazin in a program with other herbicides," said Rieckenberg, "the grower helps to preserve the effectiveness of other herbicides and decreases or delays development of weed resistance. With excellent weed control and flexible rotational restrictions, Valtera ushers in a new era of weed control."

Valtera is one of the many quality products from Valent Canada, including plant growth regulators, herbicides and insecticides. Valent's product line includes leading brands such as DiPel® Insecticide, Distance® Insect Growth Regulator (IGR), Fascination® Plant Growth Regulator (PGR), Foray® Biological Insecticide, MaxCel® PGR, Promalin® PGR. ReTain® PGR, Sumagic® PGR, VectoBac® Biological Insecticide and Velocity® Herbicide.

Saskatchewan Government Delivers for Agriculture

The Saskatchewan Government delivered for grain farmers in the 2024 – 25 budget. Allocating $570.6 billion towards a variety of programs that support the agriculture industry, grain farmers will have access to a variety of risk management programs, including Crop Insurance and AgriStability. “It is a great assurance to Saskatchewan grain farmers as we plan our 2024 growing season, knowing that these programs will backstop us,” said Daryl Fransoo, Chair. Grain farming is a key part of the provincial economy, exporting over $20 billion in agri-food products and harvesting over 31 million acres across the province. “The Saskatchewan Government understands the value that agriculture brings to our economy and hears the needs of grain farmers. Their stance on the carbon tax is a great step and one that the Wheat Growers supports,” closed Fransoo. About the Wheat Growers: Founded in 1970, the Wheat Growers Association is a voluntary farmer-run advocacy organization dedicated to developing

Research underway to benefit sustainability of swine industry

The Western College of Veterinary Medicine at the University of Saskatchewan is working to develop an on-farm tool for pork production companies to make business decisions to meet animal welfare and sustainability goals. The Natural Sciences and Engineering Research Council of Canada (NSERC) in partnership with 14 industry partners and the university provided funding for the research program in swine welfare. The program is led by Dr. Yolane Seddon. Her team of four research scientists and technicians will study data gathered from interviews with producers who make management decisions, as well as herd vets in Canada and the United States. “The outcome of this work is that we aim to produce a tool that will support decision making on the farm that will influence animal welfare, but also with the knowledge of how it interacts with business, profitability and environmental emissions and therefore, overall business sustainability goals that could influence market access,” Seddon explain
