labor issues Key for nOa in 2025-26
Story and photos by Dave Alexander, Publisher
Let’s face it – running a business and making decisions are tough these days. High interest rates, tariff uncertainty, inflation and low consumer confidence are all adding to trouble and indecision. But for farmers, perhaps labor problems trump everything.
At the National Onion Association (NOA) summer convention, held July 9-12 in Richland, Washington, Barry Vculek with Four Star Ag talked about his own labor issues. During the Legislative Committee meeting, Vculek, NOA first vice president, said that while the H-2A labor program for foreign workers has been a godsend for his farm, the program needs changes.
“It (H-2A) is becoming heavily favored to the employee versus the employer. We just got an email this morning that our Adverse Effect Wage Rate will be reported to us again tomorrow and it

goes into effect immediately. I'm sure it’s going to be up again. We’re paying guys that we have to train how to stack 50-pound bags and paying them 20 bucks an hour,” he said.
The Adverse Effect Wage Rate (AEWR) is the minimum wage that growers must pay H-2A temporary foreign workers. For Vculek, $20 per hour has made it harder than ever to make a profit. Hiring locals in oil-rich North Dakota has been impossible, as energy wages are even higher than that.
Stabilizing H-2A wages is just one facet of the Farm Workforce Modernization Act of 2025 (FWMA), currently in U.S. House committees. Previous iterations of this bill failed to clear the Senate despite passage in the House. If passed, the bill would overhaul the H-2A temporary worker program and make it possible for foreign farmworkers to get legal status. The aim is to create a more stable and efficient workforce and reduce farm labor shortages. Though no bill checks every box for every person, FWMA easily cleared the House on two different occasions, only to get stalled in the Senate.

Greg Yielding, executive vice president of NOA, Barry Vculek with Four Star Ag, Cody Anderson from L&L Ag Production and Stephen Parrott from Fort Boise Produce head the Legislative Committee meeting on the first full day of the NOA Summer Convention.
Sen. Mike Crapo (R-Idaho) originally lauded the FWMA, saying on his website, “We applaud our colleagues in the U.S. House of Representatives – on both sides of the aisle – for their work on this crucial legislation to make much-needed reforms to our immigration system for our producers and farmworkers.”
He later flipped his stance, writing that the bill did not offer a sufficient number of year-round visas and disagreeing with a clause that would have allowed H-2A workers the right to sue over workplace violations.
While the bipartisan-friendly 2025 bill will likely clear the House without difficulty later this year or in 2026 as it did in 2019 and 2021, lobbying efforts may be needed to get senators like Crapo on board.
This is where the NOA’s annual lobbying trip to Washington D.C. can help. Previous trips have been successful in getting positive changes made, and the NOA encourages all interested members to sign up for the upcoming February

2026 trip. Other issues likely to be discussed with lawmakers will be pushing for greater enforcement of the 1944 U.S.-Mexico Water Treaty and a flat-rate duty on imported Mexican onions instead of a tariff. If you’re not an NOA member, this is a good time to join and make your voice heard because the larger the group that travels to D.C., the more impact it will have.
Not everyone has the time or resources to go to Washington D.C. with the group, but you can still make a difference.
The special guest at the Legislative meeting was Rachel McClure, a staff member from the office of Rep. Dan Newhouse (R-Washington), sent to discuss the FWMA. She recommended inviting members of Congress to local meetings or proposing a meeting when a congressperson or senator is going to be in your area.
“Follow that up with an email. Say ‘thank you for meeting, here’s our points from the meeting.’ You get that message across multiple times,” she said.
Obviously, you don’t need to be an NOA member to rattle your Senator, but membership has more benefits than just the organization’s lobbying efforts. Chief among these are the conventions themselves, which have the best networking opportunities you’ll find in the industry.
And if D.C. in the late winter is not your cup of tea, Hawaii in the late fall could be your favorite drink. The NOA annual convention is Nov. 30 - Dec. 5, 2025, in Kaua’i, Hawaii. It is a combined conference with the National Allium Research Conference, expanding networking opportunities even more.

BasF-nunhems debuts short-day Onion Varieties
BASF’s vegetable seeds business, operating in the market under the Nunhems brand, has expanded its seed portfolio with the addition of three new short-day onion varieties: Adhora, Rosefire and Isidea. This rollout comes after more than a decade of research and development.
“Our strategic planning and excellent breeding program has enabled us to deliver onion varieties that provide consistent quality and meet growers’ market needs effectively,” said Kaitlyn O’Neal, regional crop lead for BASFNunhems. “Adhora, Rosefire and Isidea are bred to enhance market potential through robust quality and uniformity.”
Adhora is a yellow onion designed for Vidalia, Georgia, and Texas. It’s said to be characterized by its early maturity, excellent yield potential and distinctive sweet flavor, as well as its reliable Granex shape and market quality.
Rosefire is a short-day red onion developed for growers in California and Texas. It boasts improved bolting tolerance and superior leaf health, maintaining high uniformity and enhancing market appeal with its consistent performance.
Isidea is a short-day white onion with early maturity and robust disease resistance in Texas and Mexico. It is marketed as offering consistent bulb size, superior color, reduced variability and high yield potential.
The uniformity of each of these varieties means growers may experience less waste, according to the company. Specifically, Adhora is proven to reduce waste to 1-2% versus the industry average of 8-10%.

Onion disease Quiz
This material is provided courtesy of Claudia Nischwitz, Associate Professor and Plant Pathology Specialist, Utah State University.
Several years ago in the spring, unusual symptoms developed in some onion fields. Affected onions were scattered across a field. Samples of symptomatic and non-symptomatic leaves were collected. Until the leaves were processed the next day, they were placed in a fridge. Interestingly, the symptomatic leaves were frozen the next morning while the healthy leaves were not, providing the first clue to a potential culprit.

hard lessons and safer Onions
The Cost of Contamination and the Future of Produce Safety
By Stuart Reitz and Joy Waite-Cusic, Oregon State University
Dry bulb onions were traditionally considered a lowrisk produce item for human foodborne diseases, but three recent outbreaks that have been linked to onions have challenged that view. In 2020 and 2021, two large outbreaks (> 1,000 cases per outbreak) of Salmonella were tied to red onions, and in 2024, an outbreak of E. coli O157:H7 was linked to slivered yellow onions served on hamburgers at multiple locations of an international fast food chain.
Investigations to identify sources and causes of foodborne disease outbreaks are challenging and often fail to definitively identify the particular product that was the source of an outbreak, let alone the specific cause of how that product became contaminated (for example, the use of contaminated irrigation water). There is an inherent lag between when people become ill, when an outbreak is declared, when potential food sources are identified, and when corrective actions, such as recalls, can be implemented. Because of this inherent lag time, recalls are often implemented after much of the implicated product has passed through the chains of commerce.
Part of the belief that onions were “low risk” for foodborne diseases stems from characteristics of the crop, such as their papery wrapper scales and antimicrobial compounds produced in the bulbs. The wrapper scales of the bulbs are relatively impervious to water and protect the edible portion of bulbs from contamination; however, not all bulbs have intact wrappers, and they are not always completely removed during post-harvest handling. Onions do produce compounds (e.g., allicin and quercetin) that have antimicrobial activity when they are concentrated and purified; however, these defensive flavonoids are not active against Gram-negative bacteria, like E. coli and Salmonella, at the natural concentrations found in onions.
The onion industry has recognized the importance of proactively minimizing food safety risks. It has been a leader in produce safety efforts since the original draft Food Safety Modernization Act (FSMA) rules were issued over a decade ago. Even before the introduction of the FSMA rules, the National Onion Association (NOA) developed a best practices guide. In 2022, this guide was updated with the assistance of the International Fresh Produce Association (IFPA) and is available to NOA members online at onions-usa.org (Fig. 1).
Considering Water applications
No definitive cause of either the 2020 and 2021 outbreaks was identified, but contaminated agricultural water was cited as a potential cause, and growers should be aware of the microbial quality of water they use for irrigation, pesticide applications and other pre-harvest operations.
Commodity Specific Food Safety Guidelines for the Dry Bulb Onion Supply Chain
Our research has shown that drip and furrow irrigation pose little risk for contamination as soil naturally filters out much of the bacteria from the water as it moves from the drip tape or furrow to the onion bulbs (Fig. 2a, b). Overhead water applications (e.g., sprinklers, pesticide applications) pose higher risks for contamination because water is directly applied to the plant, contaminating the surface of the onion and can also move down the leaves through the neck into the interior of the bulb (Fig. 3). Bacteria on the outer leaves of the onion die off during the curing process; however, bacteria in the neck or interior of the bulb will be unaffected by curing and may grow during curing or post-harvest storage.
Mitigating Cross-Contamination risks
Regulatory investigations also identified cross-contamination in packing operations as a contributing factor in the outbreaks (Fig. 4). Over the last two years, we have been quantifying the risks for cross contamination between onions and food contact
Figure 1. The National Onion Association’s Food Safety Best Practices Guidelines is available to NOA members online at onions-usa.org.
Figure 2a. Researchers collect samples to study the movement of E. coli from irrigation drip tape through the soil to an onion bulb at the Oregon State University Malheur Experiment Station in Ontario, Ore.

surfaces during packing operations. Onion packing requires a dry environment, and water is generally excluded from the packing facility to prevent microbial growth. While this is a good overall strategy, the lack of regular wet cleaning and sanitation prevents establishment of a “clean break” to prevent cross-contamination between production lots. The lack of clean breaks consequently promotes largescale recalls.
To help mitigate cross-contamination risks, we have been testing the effectiveness of “dry” alcohol-based sanitizers on surfaces commonly used in packinghouses. We have demonstrated that sanitizers with an alcohol content of ~60% or more reduce bacterial loads on conveyor belts and plastic surfaces but are only minimally effective on wood. Lower alcohol products (10-30% alcohol) should be avoided because

they are ineffective and spread the bacteria, creating a larger surface area that is contaminated.
looking ahead
Upcoming research efforts will focus on using our research findings to model cross-contamination risks at commercial scale to quantify the potential benefit of using these sanitizers (Fig. 5). These models will be used to develop a web-based application so that industry members can explore and quantify the impact of implementing dry sanitation practices to support decision-making. Initial models will be shared at the joint National Onion Association and National Allium Research Conference in Hawaii in December 2025. We hope that these and other research findings will be incorporated into food safety plans for growers and shippers. Please reach out if we can be of assistance with your food safety plan.
There is more to learn about food safety practices in onion production, packing and fresh cut operations. In the meantime, we encourage growers to follow good agricultural practices to keep their crop as healthy and vigorous as possible. Minimizing pest and disease problems and other stresses are likely to reduce the risks of human pathogens contaminating onion bulbs. We encourage growers and packers to embrace produce safety as an integral component of their business because without this foundation, there could be no business to manage.

a Message From Michigan
By Greg Bird, Executive Director, Michigan Onion Committee and Michigan Vegetable Council
Asyou read this article, at least you will know it’s not AI generated, but more from the pen of someone who writes at the 10th grade level. This is from someone who took too many math classes in college and has typed too many brief emails since. So now, without further ado, here’s a look at what’s happening in Michigan.
There will be fewer onion acres in Michigan in 2025 as a large grower who farmed on sandy\mineral soil reached an opportune time to retire. Those acres did not go back to onions. I know some of those acres went to potatoes, but I wish

they had all stayed in specialty crops. I do not think any of those acres were developed into solar farms, but I know some other land did make that transition to solar this year. I hate to see the best ground leaving the vegetable industry. The volume of the 2025 crop seems good, so hopefully this makes up for those lost acres. Some onion growers are dry, but are still doing fine, while others are wet, but not too wet.
With the help of Dr. Daniel Brainard of Michigan State University (MSU) and Vriesland Growers Cooperative of Hudsonville, Michigan, the state’s onion growers have been continuing to fight off the white campion weed. Some fields are fine, but once it moves in, it is very

evasive. More field research is in place for 2025. White campion, beware: Dr. Joshua Miranda is the soon-to-start new weed scientist at MSU, and onion growers will support his efforts to get rid of white campion.
The National Onion Association (NOA) does more work for onion growers than the Michigan Onion Committee can manage. Industry information from the NOA is vital to Michigan growers. For this reason, the Michigan Onion Committee has purchased NOA memberships for each of the past three years for all Michigan growers who make their onion assessment payments.

Michigan 232 checkoff stature. The Michigan Onion Committee and the Michigan Carrot Commission are small enough that a yearly audit costs a significant chunk of the yearly budget. These organizations only have a handful of transactions a year. The bill that was passed allows 232 checkoff programs of the size of onion and carrot to only have a required audit once every five years. For continued transparency, the state agriculture department will help provide informal financial reviews as needed.
Well, I would give this article a B+ and that means I should get to borrow the family station wagon to go to the game this Friday night.

The symptoms seen in the photos are caused by a strain of the bacterium Pseudomonas coronafaciens.
The bright yellow of the leaves gives the disease its name “yellowbud.” It occurs sporadically, especially during cool temperatures. It is unknown which environmental conditions influence disease development and how they play a role. The bacteria are ice nucleating, which means they can act as a nucleus for water molecules to arrange themselves to form ice crystals at temperatures just above freezing. Under the right conditions, this can lead to frost damage of plant tissue that is colonized with the bacteria, while leaf tissue without the bacteria is unaffected.
There are two phases to the disease. In the first phase, the bacteria colonize the leaf surface. They produce a toxin called coronatine that affects chloroplasts and leads to the yellowing of the leaves. Toxin production is affected by temperature. The higher the temperature, the less toxin is produced. The toxin also opens stomates, which become entranceways for bacteria to get inside the leaves. The second phase, which does not always occur, results in leaf blight and plant death. It takes place if the plants are exposed to the toxin for a long time. If temperatures warm up quickly after initial infection, the second phase may not develop and plants recover.
For diagnosis, the bacteria can be cultured from infected leaves. Compared to other bacteria, these bacteria are very slow growing. Current management recommendations include controlling weeds which can harbor the bacteria, avoiding entering fields when leaves are wet, and applying fixed copper products tank mixed with EBDC fungicides.
