Water at the right time, Grow Bigger Bulbs

Atwo-year Oregon State University research project (2024 and 2025) examined what happens when onion irrigation is stretched in July, exactly the kind of squeeze growers can face when water gets limited mid-season. The research focused on July, when onions are actively forming bulbs and are highly sensitive to water shortages. Results showed that even a short break in irrigation during early July (July 1–15) can significantly reduce bulb size and overall marketable yield. In contrast, similar irrigation stress later in July had much less impact, suggesting that timing is more important than duration when managing limited water supplies.

Weather conditions during the study clearly explain why this mid-season period is so challenging. In eastern Oregon, both the 2024 and 2025 seasons had very low rainfall, often close to zero during peak summer months,

combined with high temperatures and rising evapotranspiration (ET) rates. As temperatures peaked in July (average high of 96 degrees Fahrenheit, with a record of 105 degrees Fahrenheit on July 10), crop water demand increased sharply while soil moisture declined rapidly due to high ET and low relative humidity. These conditions create what growers commonly call a “July drought,” in which crops depend almost entirely on irrigation. Historical data also show that drought conditions frequently occur in July in Malheur County, Oregon, making irrigation management even more critical for sustaining yields.

The study also found that simple practices such as wheat straw mulching can help mitigate the effects of water stress by conserving soil moisture and supporting higher yields under deficit irrigation. Overall, the findings highlight a clear message for growers: maintaining adequate irrigation in early July is essential for producing large, marketable onion bulbs, while carefully managed reductions in irrigation later in the month may help conserve water without major yield losses. The practical message is simple: if you have to divert water, try not to do it in the first half of July.

An Oregon State University research project evaluated how the timing of irrigation stress affects onion bulb size and marketable yield.

Out With the Old, in With the new?

What Insecticides Could Replace Radiant

SC as the Next Thrips Control Hammer in the Great Lakes Region?

Onion thrips (Thrips tabaci) management in onion is dependent on insecticide use. If onion thrips infestations are not kept in check, their feeding can severely damage the onion crop (Fig. 1a and 1b). Onion thrips also can transmit serious pathogens, such as iris yellow spot virus, which causes iris yellow spot disease that can destroy onion fields and ultimately result in complete crop loss (Fig. 1c). To add insult to injury, onion thrips populations routinely develop resistance to insecticides.

insecticide resistance

Over the past several years, onion thrips populations have been particularly challenging to manage in onion fields throughout the Great Lakes region. One reason contributing to this problem is that one of the best onion thrips control products of all time, spinetoram (Radiant SC), has become less effective. Although not confirmed, we suspect that onion thrips populations have developed resistance to Radiant SC in these areas.

Effective onion thrips management relies on protection of the crop for as long as two months, and this requires multiple insecticide applications. Because the threat of insecticide resistance is high, insecticide use recommendations are designed to minimize the risk of resistance development. A key element of this resistance mitigation strategy is to use a seasonlong sequence of insecticides belonging to different classes of chemistry and modes of action. Moreover, the use of any single insecticide should be limited. In fact, many insecticides registered on onion for thrips control are restricted to two successive applications per season. Therefore, a total of three to five insecticides are typically used to protect the crop from thrips over the course of a season.

Radiant SC was positioned in a season-long sequence during the latter half of the season when onion thrips populations were at their highest. When an infestation seemed to be on the verge of becoming uncontrollable, Radiant SC was used as “the hammer” to bring it back down. As Radiant SC becomes less reliable to combat high onion thrips infestations, a new hammer must be identified. The frontrunners are cyantraniliprole (Exirel) and the newcomer, isocycloseram (Vertento). Exirel was first registered on onion for thrips management in 2014. Exirel belongs to the anthranilic diamide class (IRAC 28), which includes insecticides that target the insect’s ryanodine receptors, causing muscle paralysis, feeding cessation and death. Vertento was first registered on onion for thrips control in December 2025. Vertento belongs to the isoxazoline class (IRAC 30), which includes insecticides that target the insect’s nervous system by binding to GABA

receptors, causing hyperexcitation of neurons and eventually death.

Evaluating alternatives

In western New York’s Elba Muck, we evaluated the ability of Radiant SC, Exirel and Vertento to control a high infestation of onion thrips. Insecticides were initially applied when thrips densities reached 11.6 per leaf. For context, the action threshold for making an insecticide application to manage onion thrips in New York onion fields is one thrips per leaf. A second application was made one week later. The rates of Radiant SC, Exirel and Vertento were 10 fl oz per acre, 20.5 fl oz per acre and 3.1 fl oz per acre, respectively, and all included the surfactant Dyne-Amic at a rate of 0.25% v:v. One week after the second application, numbers of onion thrips larvae were recorded and the mean number of thrips per leaf was compared. Results indicated that Radiant SC failed to significantly reduce the population of thrips, while both Exirel and Vertento brought the infestation down to a non-economically damaging level (Fig. 2). Exirel provided a 93% reduction and Vertento a 97% reduction in thrips densities relative to the untreated control. We have our answer: both Exirel and Vertento could be used as a hammer to manage very high infestations of onion thrips.

Exirel continues to be effective at rates of 13.5 to 16 fl oz per acre under low to moderate thrips pressure (up to two thrips per leaf), whereas a rate of 16 to 20.5 fl oz per acre is better at higher densities. Vertento is highly effective at a rate of 3.1 fl oz per acre, but the maximum labeled rate is 4.1 fl oz per acre. For both products, a non-ionic surfactant is needed to improve efficacy. In a recent study in New York, co-applications of these products with fungicides, including chlorothalonil (Bravo WeatherStik), have not compromised levels of onion thrips control.

Based on experience evaluating many different products for onion thrips control over the years, Exirel and Vertento should be used during the middle of the season when onion thrips infestations are typically most challenging to manage and when the crop is vulnerable to bulb reduction from feeding damage. Because there are many different season-long sequences of insecticides that could be used to manage onion thrips, consult me or your regional extension vegetable entomologist for details. Similar research has evaluated Exirel and Vertento for thrips control in the Pacific Northwest, so contact Stuart Reitz (Oregon State University) and Tim Waters (Washington State University) for the most current guidelines.

treasure Valley Onion school

It was Onion Production 101 at the Treasure Valley Onion School 2026. Hunter Doyle, extension agronomist for the Oregon State University Malheur Extension Service, hosted the event on Feb. 24 in Ontario, Oregon, for growers, crop advisors and others interested in an overview of onion production management issues in the area. While some of the content was geared toward those new to working with onion crops in the area, a great deal of time was spent drilling down to specific issues such as identifying different pathogens and pests that cause similar symptoms.

Doyle kicked things off with an introduction to onion and fertility basics. Attendees also heard about onion diseases and diagnosis strategy from James Woodhall with the University of Idaho, as well as irrigation management from Uday Sekaran with OSU. Bill Buhrig, also with OSU, shared guidance on

identifying the last date for fertilization and irrigation for a healthy storage crop.

OSU’s Stuart Reitz reminded attendees about the importance of being in the field, methods of field scouting, and the need to begin spraying for thrips before populations spike and not stopping too soon. He also shared information on managing wireworms, onion maggots and seedcorn maggots. A presentation on weed control in onion from Joel Felix with OSU included recommendations for controlling yellow nutsedge in each of the other crops in an onion rotation.

Plans are underway for the 2027 session of the Onion School to take place next February. Doyle says he’s considering also holding an in-field session this summer for real-time identification of weeds, diseases and pests.

Connecting Growers With industry Partners and Policymakers

In agriculture, we all know relationships matter. But for onion growers, the right connections can make a difference far beyond the field. The National Onion Association gives growers opportunities to connect with suppliers, researchers and industry peers, while also serving as a direct link to policymakers in Washington, D.C., whose decisions influence farms across the country. Representing growers in Washington is a responsibility the NOA takes seriously. Federal policies involving water access, labor, trade and food safety have both immediate and long-term impacts on onion production. The association works throughout the year to ensure lawmakers and federal agencies understand the realities of growing onions and the challenges facing American producers.

Recently, the NOA brought 21

members of the onion industry to Washington, D.C., for a series of meetings with congressional offices, administration officials and agricultural policy leaders. During these discussions, growers addressed several issues affecting the industry, including strengthening food safety systems, shaping the next Farm Bill, addressing international trade challenges and promoting fair market conditions for U.S. onion producers. These meetings allow growers to share firsthand experiences from their farms and reinforce the importance of policies that support domestic agriculture.

As with every trip to Washington, the group included both experienced advocates and first-time participants interested in learning how growers can help shape policy that affects their livelihoods. This year’s first-time attendees included Trent Weber of Weber Family Farms in Idaho and Will Beckwith of Beckwith Produce in Texas.

For Weber, the trip offered a chance to see how industry advocacy works in practice.

“I felt like it was a good opportunity to see the NOA at work,” Weber said. “Doing something is better than doing nothing. Just getting out there and expressing the concerns that we have as an industry is beneficial. I felt like there was a clear, unified message that everyone supported, and that was

important. Would I go again? Yes.”

Annual advocacy visits like this help ensure the onion industry remains visible and engaged in national policy discussions. They also strengthen relationships between growers and their elected representatives, making it easier for policymakers to understand how legislation and regulations affect farming communities. By maintaining a consistent presence in Washington, the NOA works to protect the interests of American onion growers and support policies that allow farms to remain productive for future generations.

Alongside its advocacy efforts, the NOA also serves as a hub for knowledge and collaboration within the industry. Through conventions, meetings and member engagement, growers gain access to new research, emerging technology and practical insights that can improve operations in the field.

For onion growers, membership in the NOA represents more than participation in an organization. It offers access to industry expertise, stronger connections with partners and policymakers, and a unified voice on the issues that matter most. By focusing on networking, research and advocacy, the National Onion Association helps growers address today’s challenges while supporting the long-term strength of the American onion industry.

Half of the group meets with the House Ag Committee. During the trip, members divide and conquer, meeting with state representatives and other policymakers; sometimes schedules conflict and not everyone can meet at the same time.
