ONION WORLD

A Summer Convention Do-Over

sociation Director of Public and Industry Relations

by Torrey Farms in New York. But without the energy that comes alive in person, the auction was more of a sales event, rather than an event with a little entertainment complete with great bidding wars. We can say we made a little lemonade out of the 2020 lemons, but it is time to get back to business and allow our members to engage while possibly enjoying a Bushwacker at a honkytonk down Broadway. We’re bringing back Austin Booker for our annual summer auction, which benefits the promotions fund. We’re getting some interest in big donations this year again from Top Air Inc., which earned our Promotions Champion award last year for its donation of an onion lifter. We’d encourage others in the industry to think of ways they can donate to help this auction raise money for, frankly, an amazing cause: marketing onions across the nation. All of your marketing dollars go toward putting onions in the spotlight with great recipes and promotions to get in front of a lot of people. And that doesn’t come cheap. Donations and fundraising for the promotions fund was down considerably in 2020, and we need to make up for it in 2021 while we explore new ways to keep onions as a healthy part of people’s meals and take advantage of a new culture of cooking at home. This auction is open for anyone to donate. If you feel strongly about supporting onion promotions, your donation will be accepted. Only members will be bidding on items at the convention, so you can count on your donation being picked up by someone in your industry. As of this writing, the agenda has not yet been set, but rest assured, our Executive Vice President, Greg Yielding, will be busy drumming up speakers for good discussions about hot political topics in the industry. If you’re not a member, consider joining. The National Onion Association is serious about making onions a part of the conversation that deals with ag-related policymaking. You may attend our conventions as a non-member, as long as a current member sponsors you. Feel free to call our office in Colorado to ask any questions: (970) 353-5895. Our convention this year will be July 14-17 at the Hilton Garden Inn downtown. Check our website often at www.onions-usa.org for rates and the agenda.

The scientific explanation. Calcium is a critical element for bulb development. A calcium deficiency in plants results in dividing cells being unable to stay bound together. This results in poor bulb formation, decreased overall plant health and reduced storability.

ENCOURAGE NANOCAL is a unique formulation of calcium carbonate. ®

Typical calcium soil additives have particle sizes of up to 200 microns, too big to be readily absorbed by roots. NANOCAL is milled to less than one micron. This greatly expands the calcium surface area, and allows more particles in solution, providing a denser field of calcium particles for uptake.

Foliar-applied calcium does not translocate to bulbs. The only efficient way to move calcium into developing plants is through root uptake. Soil-applied NANOCAL’s particle size allows immediate movement into the meristematic region of growing roots. TransXylem™ technology translocates the calcium throughout the plant to rapidly dividing cells in the developing bulbs.

Soil-applied NANOCAL calcium particles are immediately available to developing bulbs.

Benefits of improved calcium uptake include: • Reduction in calcium-deficiency quality issues • Improved shelf life and storability • Better uniformity at maturity • Increased firmness • Increased yield

Utah Onion Association Winter Meeting

Utah Growers Zoom in on Latest Research By Dan Drost, Utah State University

he Utah Onion Association joined the ranks of organizations opting for virtual meetings this winter. While the online meeting, held Feb. 9, did not allow the grower interactions that attendees enjoy at the annual in-person gathering, the meeting was well attended and provided an opportunity to highlight topics including onion irrigation management and crop health.

Irrigation Management

Niel Allen, a Utah State University (USU) irrigation specialist, reported on the 2019-20 Onion Water Use project. “Utah House Bill 381 provided the funding to assess irrigation technologies designed to use less water, to help Utah farmers stay in agriculture while saving water, and identify systems that maintain productivity and profitability,” Allen said. Onions were one of the crops chosen to “document water depletion or consumptive water use” from drip- or furrow-irrigated fields. Allen described the trial setup and highlighted the water use differences between furrow- and drip-irrigated fields. In the furrow-irrigated onions, calculated ET was about 0.2 inches of water per day during July and August. Differences in water use between the furrow- and dripirrigated fields were noticeable. Furrow fields received about three times as much water as the drip fields. This extra water resulted in both deep percolation and surface runoff (tail water) at the end of the field. “Distance from the inlet in the drip fields impacted soil water content and crop yield more than it did in furrowirrigated fields,” Allen noted, adding that therefore, both water volume and system design can influence crop performance. He went on to describe how friction loss down the drip line can affect water delivery, and this helps explain variable

Onion World • May / June 2021

yields across a field. He recommended that growers monitor onions in low water delivery locations, carefully design dripirrigated fields and consider using sensors to help track water use.

Bacterial Diseases

Claudia Nischwitz, a USU plant pathologist, provided a detailed update on the national “Stop the Rot” project. “Stop the Rot” was designed to identify and manage bacterial diseases that affect onions in the field and storage. Bacterial diseases are difficult to manage due to a lack of detection methods. In addition, there is a poor understanding of the genetics of pathogenicity, limited resistance in existing cultivars and few chemicals to help control these pathogens. Utah is participating in two of the “Stop the Rot” objectives. During the 2020 production season, Nischwitz’s research team surveyed onion fields (Objective 1) across Utah for bacterial diseases, collected samples and identified those pathogens in the laboratory. Collected bacterial samples were then assayed to see if they cause disease in the laboratory or greenhouse. Nischwitz reported that bacteria species collected in 2020 included Enterobacter, Pantoea, Pseudomonas, Serratia and Berkholderia. In addition to the field survey work, Nischwitz described the field trial conducted to evaluate bactericides that might control rots in onions. The trial tested some chemicals that might help reduce bacterial rots both pre- and postharvest (Objective 2). In 2020, eight chemicals were evaluated in a replicated trial. Onions were inoculated with Pantoea allii and the different control agents applied five times. Bulb samples were put in storage and then further evaluated after three months. Bacteria were sampled from diseased bulbs and

species were identified and pathogenicity tested. “Utah commonly has few bacterial diseases due to the dry conditions experienced during the growing season. However, growers need to know what problems are potentially out there and how to mitigate infection risk both in the field and in storage. This work should help improve onion sustainability and profitability,” Nischwitz said.

Leafminer Detection

Nischwitz also described her continuing efforts to identify and document the extent of leafminer injury in Utah onions. In 2020, the only leafminers found in Utah onion fields were Liriomyza species. While leafminers were found in many onion fields, they do very little damage, did not affect productivity and are not considered a threat. Using a specialty crops block grant from the Utah Department of Agriculture and Food, Nischwitz’s efforts will help growers better monitor leafminers. With a detection system in place, growers will have the tools to deal with the more serious Allium leafminer, should it arrive in Utah. “While the Allium leafminer (Phytomyza gymnostoma) is still only found in some eastern U.S. onion production areas, we need to be sure we have ways to detect it, should it come this way,” Nischwitz advised. She noted that she regularly finds leafminers in green onions purchased at local grocery stores. However, the species present were leafminers commonly found in Utah onion fields, she said.

Industry Issues

The meeting also included comments from Greg Yielding with the National Onion Association (NOA) outlining some of the national issues important

to the onion industry. Topics included how the NOA supports the enhanced crop insurance coverage option managed by the Risk Management Agency. Other topics of interest included the Biden administration’s request for EPA to revisit some of the environmental rulings from the prior administration. NOA is interested in Utah growers’ use of Lorsban and its importance to the industry. Yielding then discussed issues related to trade, using examples to help growers better understand how the markets work and how to help protect the U.S. onion industry. “We need to stay on top of this to ensure onion movements are fair, treaties are accurately interpreted and local pricing is not adversely affected by imports,” Yielding said. The Utah Onion Association plans to hold an in-person summer field day in the Davis-Weber counties production region on Aug. 10.

Less is More Reducing Inputs Benefits Onion Production in Muck Soil By Karly Regan and Brian Nault, Department of Entomology, Cornell AgriTech, Cornell University

rofitable management of any agricultural crop requires optimizing the costs of chemical inputs such as fertilizer and pesticides to maximize crop yield. Another important consideration is to minimize potential negative impacts of chemical inputs on the environment such as pollution and pesticide resistance. In this article, we focus on how reductions in fertilizer and insecticide use impact onion yield, onion thrips control and bulb rot. Management of onion thrips relies on insecticides to protect foliage from feeding damage and subsequent yield reduction, but also to minimize spread of pathogens that cause foliar and bulb diseases (Fig. 1). In New York, onion thrips typically have three or four overlapping generations each season, requiring multiple insecticide applications. Consequently, insecticide resistance management is really important. Action thresholds have been developed for onion thrips in onion to guide

B Figure 1. Adult and larval thrips tend to cluster near the growing point of onion plants (A) with the larval stage, which is wingless and paler yellow than the adults, causing most of the damage. Feeding by larvae when infestations are high can lead to loss of chlorophyll, making plants appear white (B). Thrips feeding can exacerbate many onion diseases, including bulb rots (C).

The number of sprays applied in each program is denoted within each bar to show the range applied to all fields in this trial.

decisions on when to make an insecticide application. In New York, the most common action threshold is one thrips per leaf. The best insecticides applied at this action threshold have consistently kept average thrips densities below an economic injury level of 2.2 thrips per leaf over the course of the season, which prevents yield loss. Although action threshold adoption has shown benefits for reducing insecticide applications and insecticide costs, thrips management still relies on insecticide use as the primary tactic. Thus, there is a need to identify additional tactics to improve integrated pest management of onion thrips. A cultural tactic that might hold potential for managing onion thrips is applying less fertilizer. For onions grown on mineral soil, onion thrips populations were reduced by 70 percent when less nitrogen was applied. An additional benefit of reducing nitrogen in onion was a reduced incidence of bulb rot.

Optimizing Chemical Inputs to Manage Thrips, Bulb Rot

Our study was conducted in eight muck fields in western and central New York, all of which were planted with a full-season, yellow onion cultivar. Within each field, an area was divided into three sections that received either a full rate of fertilizer that the grower would typically apply, half of that rate and no fertilizer at all (Table 1). Within each fertilizer section, a sub-section was treated weekly with an insecticide spray, while the remaining area was only sprayed following an action threshold of one thrips per leaf. The weekly spray program began in late June and ended when growers made their last application in late August (seven to eight weeks total). Although there were slightly more thrips in sub-sections of the field treated with insecticides following an action threshold compared with thrips densities in those following a weekly spray program, average thrips densities over the season remained below the economic injury level (Fig. 2). More importantly, onion yield was identical between the two spray programs (Fig. 3). This means that the action-threshold program worked exactly as it was supposed to by preventing thrips populations from reaching an economically damaging level. Action threshold-treated areas received an average of five sprays compared to seven sprays in the weekly treated areas, allowing growers to save two sprays per season. Over large production areas, this has the potential to add up to big economic savings without any reduction in yield. Where fertilizer rates were reduced, we saw no impact on either thrips densities, onion yield (Fig. 3) or bulb rot incidence (Fig. 4). In soil samples taken in early May and mid-July, we detected higher levels of nitrogen (N) and potassium (K) where a half or full rate of fertilizer

In New York, most onions are grown on muck soils that have a high organic matter content, which can help retain nutrients. Over the past two years, we investigated how reducing fertilizer levels in onions grown on muck soil might reduce thrips infestations and bulb rot. Additionally, we wanted to investigate whether reduction in fertilizer use coupled with an action thresholdbased insecticide program might provide outstanding thrips and bulb rot control, but reduce overall chemical inputs.

Conclusions

Overall, reducing chemical inputs such as fertilizer and insecticides is a great way to save money, increase profits, minimize pollution and likely delay insecticide resistance. Although we did not improve management of thrips or bulb rots by reducing fertilizer rates, there were no negative impacts of reducing fertilizer. We encourage growers to continue soil testing and apply fertilizer based on fertility recommendations, rather than applying fertilizer that is not needed, increasing costs and potentially causing pollution. With no negative impact on yield, we claim that less is more.

was applied relative to no fertilizer (Fig. 5). In contrast, levels of phosphorus (P) did not differ between soil that received fertilizer and those that did not. Even in the plots receiving no fertilizer, we detected phosphorus and potassium levels at or above optimum levels when sampled shortly after planting, indicating that there are substantial stores of nutrients retained in muck soils after years of onion production. Many of these fields would not have needed P and K applied if fertilizer decisions had been based on soil test recommendations. Thus, we have learned that there is certainly potential to reduce applications of N-P-K to save money without impacting yield.

Stop the Rot

Progress Report

Stop the Rot: A National Collaboration to Research, Combat Bacterial Diseases of Onion By Heather MacKay and Lindsey du Toit, Washington State University

he Stop the Rot project team has completed the first full season of field and lab work. The goal of the Stop the Rot project is to develop practical, economically sound strategies for bacterial pathogen detection and management that will improve profitability and sustainability of onion production. It is vital that the research addresses industry priorities and provides tools that will be useful for growers. Findings from stakeholder surveys in our first year of research confirmed that bacterial diseases and economic losses due to onion rots are a significant economic issue for the onion industry. All the groups surveyed agree that there is no single highly effective management strategy for reducing economic losses and that a combination of diagnostic tools, treatments and management strategies will be needed.

Understanding Bacterial Pathogens

From late 2019 through 2020, researchers across six onion growing regions in the U.S. collected symptomatic onion leaves

• Onion Top Tailer • Field Toppers • Loaders • Nicholson Parts Available

and bulbs from fields and storage facilities, from which bacteria were isolated for identification and pathogenicity testing on onion. The purpose of this national bacterial survey, which will be repeated in the 2021 and 2022 seasons, is to get a snapshot of the many types of bacteria present in onion crops across the U.S. While we know Burkholderia, Pantoea, Enterobacter and Xanthomonas are the most common genera of bacteria that cause diseases of onion, and our first year’s bacterial survey turned up these “usual suspects” around the country, we found a surprisingly broad diversity of other bacterial genera associated with symptomatic onion leaves and bulbs. The surveys will help us understand which bacteria are prevalent in different onion production regions and what their roles might be in the progression of bacterial diseases of onion. Genetic research will be completed with selected pathogenic bacteria from the surveys with the goal of understanding which genes enable these bacteria to cause diseases of onion. Our team is developing molecular diagnostic tools to allow rapid identification of the pathogenic bacteria, which will help growers respond more effectively to infections in their crops. In the 2021 season, we will be testing methods for detecting onion pathogenic bacteria in soil, irrigation water and other potential sources of inoculum.

Field trials were designed by this team to assess the efficacy of a range of practices and treatments on bacterial diseases, many of which are currently used by growers. The last evaluations of onions in storage from these trials were obtained in February 2021, so we are updating the trial reports with these data to share with onion stakeholders.

Irrigation, Fertility

Four states conducted trials in 2020 to assess how irrigation and fertility practices affect onion bacterial diseases. Preliminary results suggest further research is warranted to assess if earlier termination of irrigation can reduce bacterial bulb rot under conditions of high disease pressure without adversely affecting bulb yield.

Bactericides

Bactericides were evaluated in replicated field trials across seven states during 2020: Colorado, Georgia, New York, Oregon, Texas, Utah and Washington. Seven onion cultivars were included across the sites (Avalon, Calibra, Century, Granero, Redwing, Salute and Vaquero), and 22 products were evaluated across the trials. An onion sampled from a field in 2020 shows internal symptoms of bacterial rot. Onions were sampled from growers’ crops in 10 states in 2020 to determine which bacteria are associated with bacterial diseases of onion across regions of production in the U.S.

Cultural, Post-Harvest Practices

We tested various late-season cultural practices in field trials in Georgia, New York and Washington to see how these influence bacterial diseases. These included variations in practices such as the timing and method of topping onion bulbs, rolling the tops and undercutting bulbs, as well as harvest methods (mechanical vs. manual). The trials will be repeated in 2021, along with a trial in Georgia to evaluate the impact of onion neck length after topping on development of bacterial bulb rots. We also tested four commercially available products applied to onion bulbs after harvest to assess the efficacy of these products at suppressing bacterial bulb rots in storage. The trial was completed in a simulated storage facility, and a video of the setup is available at youtu.be/VSExAvjJAT8. Final results will be shared this summer.

What’s Next?

The 2021 bacterial surveys have commenced in early onion production regions in Georgia and Texas. Many of the field trials will be repeated in 2021, and the Washington state team is adding trials to investigate the interaction of select herbicides with bactericides for managing onion diseases. Extension publications, research summaries and disease notes covering results of the first year of the Stop the Rot project will be published in summer 2021. These, along with other information the team generates, will be available at www.alliumnet.com/projects/stop-the-rot.

Onion Quiz Answers From page 11

Photo A depicts dodder (Cuscuta spp) entangling onion seedlings. Dodder is a parasitic weed that derives all of its nourishment from a susceptible host. Once the seed germinates and emerges, it has to find a host (which it does with precision) within five to 10 days or risk withering off and dying. Dodder lacks roots or the ability to photosynthesize, thus deriving all of the nutrients by parasitizing the host. It produces a large number of seeds that could remain viable in the soil for over 20 years.

Vidalia Onions Hit the Market

Vidalia onion producers began shipping onions April 19, this year’s official pack date set by the Georgia Department of Agriculture and the Vidalia Onion Committee. The pack date is determined by soil and weather conditions during the growing season to help ensure only the highest quality Vidalia onions, known for their sweet, mild flavor, are shipped to stores. Approximately 10,000 acres of Vidalia onions were planted for the 2021 season. This year marks the 35th anniversary of the passage of the Vidalia Onion Act by Georgia’s legislature. The Vidalia Onion Act established that only sweet onions grown in 20 southern Georgia counties from a distinctive Granex seed and packed and sold on or after the official pack date each year can be called Vidalia onions. Hand-cultivated by 60 registered growers, Vidalia onions represent about 40 percent of the nation’s sweet onion market and are sold in every state.

Kentucky Derby Menu Features Vidalia Onions

Vidalia onions are bringing a touch of extra sweetness to this year’s Kentucky Derby. For the first time, the Vidalia Onion Committee is partnering with the Kentucky Derby as an event sponsor. Vidalia onions will be featured in two dishes on the official Churchill Downs Kentucky Derby menu. Guests at the racetrack for “The Run for the Roses” will be served a Chicken with Vidalia Onion and Mushroom Sauce and a Vidalia Onion, Bourbon Sorghum Vinaigrette on a Black Eye Pea Salad, both crafted by Churchill Downs’ executive chef. The Kentucky Derby posted recipes for both dishes on its website.

From the NOA

Get Ready for an NOA Summer Convention Do-Over By René Hardwick, National Onion Association Director of Public and Industry Relations

t’s 2021. Do you see your shadow? Having been cooped up for the better part of the year, we hope you will join the National Onion Association in Nashville, Tennessee, this summer. That’s right, we’re getting a do-over. We’re going to spend four great days in the Music City, with lots of people needing to get out and mingle, have a little fun and do a little business. Now, we tried the online thing. And we learned a few lessons. First, online meetings may be the next best thing, but tell us the truth. Were you even engaged in the last Zoom meeting you were in, or were you checking emails like many others, hoping to get a little work done while you listened? The energy of human interaction just isn’t there. The NOA’s summer online convention attracted roughly half of the people we normally get the pleasure of visiting with each summer. And our online summer auction was a pretty good one this year, even though it was held in cyberspace. In fact, we had some of the best donations we’ve ever had, such as an onion lifter by Top Air Inc., a south Texas deer hunt by Fox Packaging and a great getaway on Lake Ontario, complete with a day fishing charter,
