Rietveld Equipment

When a flight took us to the Midwest, in the vicinity of Rietveld Equipment, we took the opportunity for another road trip. A new showroom, built to display and demo the company’s post-harvest equipment, was available for touring.

We were able to see brand new machines set in place, not yet wired. But visitors will soon be able to test drive this same equipment as potatoes are washed, sorted and boxed on site.

Run by father and son John and Nick Rietveld, the company sells individual pieces of equipment, but can also design and build complete packing facilities.

New post-harvest machinery on display at Rietveld Equipment will be wired and processing spuds this year, giving customers an up-close look at how the equipment works. The Rietveld Farm Stand opens mid-July and runs for about three months. Future plans include a greenhouse, which will allow the family to open the stand earlier in the year and possibly expand into flowers. Spare parts are in stock at Rietveld Equipment to keep customers up and running. Nick Rietveld demonstrates the controls on an Allround destoner.

The Rietveld family has grown onion sets for five generations on their own or rented property about 60 miles south of Chicago. Due to an ever-decreasing retail market, Canadian competition, increasing input costs and lack of labor, the Rietvelds made the tough decision in 2023 to quit growing onion sets.

They continue to grow sweet corn and sell it at their own farm stand, along with salsa and other locally grown produce. They even sell some imports – namely, Vidalia onions – at the stand. Nick said people drive from up to two hours away to buy their corn and salsa, and they sell as many as 6,000 ears of corn a day.

Eliminating onion cultivation from their farm’s day-to-day routine has opened up more time for John and Nick to spend on Rietveld Equipment. They sell, service and install top-notch machines from European manufacturers including Meconaf, Allround, Upmann, VHM, IPLA, Teneco and Intec.

Farm Bill, Food Safety, Frivolities

The National Onion Association (NOA) Summer Convention was held June 14-17 in Grand Rapids, Michigan. Outside, Grand Rapids was cool and pleasant. And the city was convenient and close to three onion-related stops that were on the NOA Ag Tour. Inside, committees met, members dined, auction items sold and speakers talked about the 2023 Farm Bill and the everpresent topic of food safety.

Farm Bill

The NOA general session featured a taped appearance from U.S. Sen. Debbie Stabenow of Michigan, chairwoman of the U.S. Senate Committee on Agriculture, Nutrition and Forestry. She shared her thoughts on the impending Farm Bill, which is legislated every five years and comes before Congress again this year. In the 2018 Farm Bill, Congress included permanent, annual funding for specialty crop block grants, research and trade programs. Stabenow has spent her career advocating for specialty crops like onions, she said, and specialties are still frontline for her.

“I’m committed to protecting the progress and permanent investments we’ve made while looking for new and innovative ways to expand risk management opportunities and boost markets at home as well as abroad,” Stabenow said.

But Barry Vculek, owner of Four Star Ag in North Dakota and a member of the NOA Legislative Committee, said money going to agriculture may not be what it seems in the new Farm Bill. He said as much as 80 percent of the total funds could be going to subsidy programs such as the Supplemental Nutrition Assistance Program (SNAP).

Stabenow said she often hears that labor shortages are a real problem for farmers and “Congress must get serious about labor reform.”

Addressing labor, Vculek said the Adverse Effect Wage Rate has raised wage levels in all states and it’s “seemingly getting out of hand.”

He is required to pay $18 an hour for “laborers to throw 50-pound bags” – whether employing locals or H-2A workers.

Specifically referencing H-2A, Vculek warned, “It seems like the government is trying to make this program more restrictive and more expensive for us on a daily basis.”

The U.S. Senate Committee on Agriculture, Nutrition and Forestry is still seeking feedback and taking ideas and proposals for the 2023 Farm Bill at www. agriculture.senate.gov/farm-bill or by email at farmbill2023@ag.senate.gov.

Food Safety

Food safety has been a constant focus of NOA meetings for the last couple years, so it was no surprise that Rebecca Anderson with GlobalG.A.P. appeared via Zoom with a presentation that included food safety tips and how to implement them.

Anderson stressed the importance of appropriate, achievable food safety operating practices and advised putting checklists in place to get organized and to ensure workers’ compliance. Employees need to have information resources, and policies should be in place. Policy training meetings are critical, but can get overwhelming and stagnant when they remain the same, year after year. Breaking them into monthly meetings or by topic will help workers stay engaged.

Brett Goodwin, VP of marketing with Carbon Robotics (foreground), explains the benefits of using the company’s LaserWeeder, a machine that uses AI to burn weeds and not onion shoots. NOA attendees hear a live Zoom discussion of the Farm Bill from Brandon Honeycutt, a senior professional staff with the U.S. Senate Committee on Agriculture, Nutrition and Forestry. U.S. Sen. Debbie Stabenow from Michigan also delivered a taped welcome and touched on the Farm Bill.

Companies also want to ensure all employees have a voice, from frontline workers, to managers, to owners, Anderson said. Employees should be encouraged to speak up and give input, but also accept accountability.

Anderson reminded attendees that food safety is a year-round concern. Sanitation and cleaning of equipment, grounds maintenance, water supply, hand washing stations, restrooms and waste management should always be considered, but remain on the lookout for new or different methods and technology to improve and make things easier.

The next NOA get-together will be the Annual Convention in San Antonio, Texas, Nov. 29 – Dec. 2, 2023. This meeting and the National Allium Research Conference will be held together, so high attendance is expected. Early hotel reservations are encouraged at www.onions-usa.org/ members/conventions.

Mistaken Identity

Using DNA Evidence to Address Cases of Mistaken Identity of Bacteria Causing Onion Diseases

e have shared several reports in Onion World over the past few years on the “Stop the Rot” onion bacterial project. The project has two main areas of focus on bacterial diseases that affect onion production across the U.S.: 1) understanding the diversity and prevalence of bacteria that cause onion diseases, and 2) determining how to manage these bacterial pathogens more effectively.

As part of the first objective, we are taking a close look at the genetics (DNA) of the numerous bacteria we have found in onion crops surveyed around the U.S. over the past three years. You might ask “So what? Why is this important in order to manage onion bacterial diseases?”

Distinguishing the Good From the Bad

Genetics of onion bacteria are important to distinguish the good from the bad. Many species of bacteria can cause diseases of onion. Even more bacteria can make a “happy home” inside a rotting onion once another pathogen starts to break down onion tissue. This can make it extremely difficult to get an accurate diagnosis of which bacterium is the primary culprit for causing an onion to rot and which ones are “along for the ride.”

In three years of onion surveys for the Stop the Rot project, we have isolated more than 5,000 bacterial strains that belong to more than 110 different genera. A majority of these bacterial isolates do not cause onion diseases.

Sometimes, diagnosing the species of the bacterium is not enough. A prime example is the center rot pathogen, Pantoea ananatis. We routinely recover isolates of P. ananatis that are aggressive pathogens of onion, but we also routinely recover isolates of P. ananatis that are harmless (not pathogenic) as they are not able to cause disease symptoms on onion bulbs or plants. Sometimes, pathogenic and non-pathogenic strains of P. ananatis can be isolated from the same onion plant or bulb. This is similar for several other bacterial species with strains that can cause onion diseases and strains that are not pathogens of onion. This kind of situation can lead to mistaken identity and misdiagnosis of the primary pathogen; a strain that is “along for the ride” may get “accused of committing the crime.”

The variation in ability of bacterial strains to cause diseases of onion can be the result of genetic differences among strains of the same species. A bacterial cell reproduces by splitting into two perfect clones; this is often called vertical transfer of genes, analogous to genes inherited by children from their parents.

However, bacteria also can trade snippets of genetic material (DNA) with each other, a process often called horizontal transfer of genes.

Usually, bacteria trade pieces of DNA in this manner between cells of the same or closely related species, but sometimes they can trade pieces of DNA with bacteria of other species. Even though DNA trading is relatively rare, it can have big consequences. For instance, bacterial gene trading is one of the ways that antibiotic resistance genes and genes for copper resistance spread among bacteria, undermining the effectiveness of antibiotics and bactericides. This is similar to the situation where some strains of Escherichia coli bacteria contain genes for toxins that give people food poisoning, whereas most strains of E. coli lack those genes and are harmless or even helpful members of the bacterial community in your digestive tract. Likewise, pathogenic and non-pathogenic bacteria can trade pieces of DNA when they are colonizing an onion together. This could turn the “saprophytes” (harmless bacteria) into pathogens of onion.

Developing DNA Diagnostic Tools

One of the overall goals of the Stop the Rot onion bacterial project is to develop diagnostic tools so that accurate diagnosis complements effective, pathogen-specific, targeted disease

management strategies for various regions of onion production around the U.S. Currently, the primary method of diagnosing bacteria pathogenic to onion entails isolating bacteria from symptomatic tissue, and then characterizing the isolates and inoculating healthy plants to see if the isolates cause similar symptoms to what was observed on the original tissue. This can take weeks or even months to perform. DNA-based testing can be robust, rapid and relatively easy to standardize and can reduce the risks of “mistaken identity” with a non-pathogenic strain being diagnosed as the cause of the disease.

Sequencing the genome of a bacterial strain entails reading the individual letters (C, A, G and T) in the sequence of all the DNA in that bacterium. The sequenced genomes of pathogenic strains and non-pathogenic strains of the same species of bacterium then can be compared to identify specific genes found only in the pathogenic strains. For instance, we’ve learned that onion pathogenic strains of P. ananatis carry genes to synthesize the compound pantaphos, which is toxic to onion plants and allows the bacteria to cause onion leaf blight and bulb rot. The next step is to develop a DNA-based diagnostic

tool that can be used to identify whether a bacterial strain contains the cluster of genes that produce pantaphos.

Progress

Developing DNA diagnostic tools requires a lot of testing to confirm the tool does not give false positive results (indicating a strain is a pathogen of onion when it is not) or false negative results (indicating a strain is not a pathogen when, in fact, it is). Since the DNA of every species of every genus of bacteria is different, the genes that confer pathogenicity in Pantoea agglomerans may not be the same as those in P. ananatis, Burkholderia species, and the many other bacteria that are pathogens of onion. Since there are numerous bacteria that can cause diseases of onion, developing DNA diagnostic tools for identifying specific bacteria that are pathogens of onion takes a lot of testing and time.

The Stop the Rot project has focused initially on developing diagnostic tools for strains of Pantoea that are pathogens of onion because this is one of the most common bacteria found in diseased onion crops and bulbs across the U.S. and many

non-pathogenic strains of Pantoea also are found on onions. This research also has helped us identify strains of bacteria that carry genes for copper tolerance, i.e., genes that enable the bacteria to grow in the presence of copper. We are now testing whether the presence of bacteria with copper tolerance genes in onion crops might explain why applications of copper sprays in field trials across the U.S. typically have shown very poor control of bacterial diseases. We look forward to sharing these results in the near future.

Onion Weeds Quiz

Weeds are commonly found in most crop fields. Weed diversity in different fields is governed by many factors, including the level or intensity of tillage, soil fertility, crop rotation practiced, and whether organic or conventional farming. Successful management of weeds depends on our ability to correctly identify them, particularly at the seedling stage in order to avoid seed production.

Crop rotation is a well-proven strategy for preserving healthy soil; it’s important to rotate your onion crops to other land parcels. Different varieties pull varying levels of moisture from the ground and have different root sizes, which impacts the soil over time. Further, varying produce types will affect the pH of the soil differently; healthy soil shouldn’t be too acidic or too alkaline. By rotating varieties, these factors even out, thereby improving soil health, reducing fungus attraction and increasing production.

Monitor contract pricing.

Just like managing a 401(k), it’s important to take an informed, longterm approach to contract pricing. Onion contracts should be carefully evaluated and then re-evaluated as time goes on. Farmers should keep their options open, for example, looking into options such as specialty crops.

Manage input costs broadly, beyond fertilizer.

Skilled crop management can reduce backfill soil costs. By considering variables such as high temperatures and drought, farmers can apply crop rotation strategies to keep soil nutrients high and fertilizer costs low.

Manage in-field threats.

Unstable fertilizer costs aren’t the only issue challenging onion growers. Timing when to spray for weeds with chemical herbicide treatments is a continuous discussion if flaming isn’t being used. Destroying the seedbed of the weed before the onion seed has germinated is ideal. In addition, managing insecticide and disease control plans, as well as

implementing those plans, on a regular basis also keeps growers increasingly busy.

Fluctuating prices and supply chain issues are not anticipated to resolve any time soon. Consequently, running a successful onion growing business requires planning, growing strategies and actively evaluating different financial and land cultivation strategies and options.

Lender Predicts Slightly Profitable Returns

AgWest Farm Credit has released its quarterly Market Snapshot report covering the state of major agricultural commodities in its northern region of Idaho, Montana, Oregon, Washington and Alaska.

AgWest’s profitability outlook for onions suggests slightly profitable returns. Wet conditions slowed early onion development in the Northwest, but summer heat is expected to help onions bulk up. According to the report, strong demand and prices for onions were offset by increased production costs.

Nunhems Increases

DISINFECTING

Availabilty

of Tearless Sweet Onion Variety

The S7210 tearless sweet onion variety Sunions, from BASF’s vegetable seed brand Nunhems, is now available for all U.S. growers to purchase for the 2024 growing season. Growers will have the option of marketing the variety under the Sunions name or under their own brand.

S7210 was launched in 2017 with limited seed quantity and no market presence. Now the company says it has built up its seed inventory and created retail market pull, allowing sales to all interested long-day onion growers.

With the S7210 variety, domestic growers can produce a sweet, long-day onion that’s both tearless and available during winter marketing months. A consumer marketing survey found that the S7210 produced less burning sensation, tearing, nose running, throat irritation and overall irritation than other sweet onions.

Stokes Seeds Partners with PlantTape

Stokes Seeds has formed a partnership with PlantTape to serve as the recommended seed supplier to PlantTape customers across the eastern half of the U.S. and Canada. With this new arrangement, Stokes Seeds and PlantTape will collaborate to supply growers utilizing PlantTape technology with seed for the planting system.

PlantTape is an automated transplanting system in which seeds are sown into the PlantTape material, which is cut into strips and placed into trays. Seeds germinate in a greenhouse and are then transplanted into a grower’s field, with the PlantTape transplanter cutting the strips between plants and placing each seedling into the soil.

Seed will be warehoused at the PlantTape facility in Livingston, Tennessee, to facilitate timely order processing and movement of seeded plant tape to greenhouses.

Photos A and B are of common lambsquarters (Chenopodium album) seedling and mature plant, respectively. Common lambsquarters emerges very early in spring, normally when <150 growing degree days have accumulated. Early emergence necessitates some level of control (chemical or mechanical) before crop planting. Common lambsquarters seed could retain viability for more than 40 years in the soil.
