Maximizing Efficiency at Terra Gold Farms Story and photos by Denise Keller, Editor

ith high input costs and a short labor supply, efficiency is more essential than ever for potato growers like Austin Ochoa. As chief operating officer at Terra Gold Farms in Othello, Washington, Ochoa is utilizing technology to compensate for the current lack of available manpower. During the last two growing seasons, Ochoa has been unable to find the people needed to operate the family farm the way it needs to be run, he says. The potato industry is competing for workers with other industries in the Columbia Basin, where companies including Amazon, Reser’s and Darigold are growing. As a result, the farm is operating with 75 percent of a crew. In spite of a smaller labor pool, the farm’s payroll continues to become larger. This year, the minimum wage in Washington state increased to $14.49 and agricultural workers became eligible for overtime wages. As the farm’s expenses are increasing, margins are getting slimmer. And while Ochoa wants to provide a living wage for members of his community, he also needs to run a profitable business. “What all these extra expenses are coming down to are us finding new ways to grow and harvest a crop with the same number of people in a shorter amount of time or fewer people for the same amount of time,” Ochoa says. “That’s what we’re looking at. What can we do to still provide for these people but still make sure our business isn’t suffering?”

Constant Improvement

It has been a learning experience for Ochoa to hire key players who share his goals and vision for the farm. As a fifthgeneration farmer, Ochoa says the family strives to streamline operations each year and keep an open mind to trying new

products or practices, with crop quality remaining the primary focus. “We’re always trying to expand on our technology because we want to be able to utilize as much as we can. If we can’t, we might be creating extra work somewhere else where we could bring in some new technology to take away some extra tasks to allow people to be more productive elsewhere,” the grower explains. In light of the recent shortage of labor, Ochoa has been working to make operations particularly efficient and to reduce labor expenses with new equipment. In 2021, the farm purchased new planters, windrowers and a harvester. Utilizing two windrowers allowed crews to dig 60 percent more potatoes in each pass through the field. In addition, the new digger equipped with an airseparation table left more dirt, rocks and debris in the field instead of hauling it to the storage, saving transportation costs and requiring fewer employees to clean spuds going into storage. With the new equipment, the crew dug 4,000 tons of potatoes per day in 2021 compared to Extreme heat last summer resulted in quality issues including misshapen tubers.

Employees sort out debris as freshly harvested potatoes make their way into storage.

3,500 tons per day in previous years, and the investments reduced harvest time by 30 percent. “I think the future of the potato industry is learning to be the most efficient you can be. And I think you’re always going to have to have quality in mind, especially with the exports we do out of Washington state,” Ochoa says. “You have to have good quality, you have to be efficient, and you have to keep growing and raising a good quality product.” Aside from harvest, Terra Gold Farms continuously evaluates its in-season processes and looks for opportunities to improve, from the use of soil sampling to telemetry on pivots, as well as variable rate fertilizer and chemical applications. The farm also began using aerial imagery within the last few years to better monitor water stress and disease and weed pressure. PotatoCountry.com

Terra Gold Farms “I’m the type of person who likes to gather all the data and make an informed decision on all that data. So I think we’re able to make better decisions with all this technology,” Ochoa says. “We’re really saving costs and we’re able to have a better product by making those types of informed decisions.”

Family Farm

As Terra Gold Farms continues to embrace technology and expand, it remains a family-owned and operated business. Austin’s parents, AJ and Jodi Ochoa, own the farm, and his sister, Callie, works in the office. Terra Gold Farms grows Russet Burbank, Clearwater Russet, Ranger Russet, Shepody and Alturas, mainly for processing, with approximately 20 percent of the crop grown for the fresh market. The farm also grows onions, corn, hay, grass seed, beans, peas and wheat. Potatoes have been in the Ochoa family’s rotation for five generations. Austin’s great-great grandfather moved from Mexico to farm in Sunnyside, Washington, and then in the Othello area. AJ farmed with his father and brothers before he started Terra Gold Farms. Austin grew up on the farm and returned to join the operation after college in 2017. “I’ve been on the farm ever since I can

remember. My dad packed me around in the pickup, taking me to meetings, digging fields, talking to anybody and everybody, so I’ve started from the bottom and worked my way up,” Ochoa recalls. “So I understand what it all takes to get a crop out of the ground, from weeding to the water, from the fertilizer to the chemicals, from planting to harvest. I understand the whole operation, so that’s why I’m in the position I’m in now.” In addition to his duties on the farm, Ochoa is beginning to take on leadership roles within the industry. After attending the Potato Industry Leadership Institute in 2020, he joined the Potatoes USA board and the Washington State Potato Commission’s research and outreach committee. “The Potato Industry Leadership Institute opened my eyes to how much more of a difference you can make just by going out and talking to people and being an advocate for agriculture,” Ochoa says. “I could go out and promote potatoes and promote what I do and try to get more people to understand what we do for the entire world.” It’s an industry he is proud to promote and a livelihood he’s grateful to have. “What I love about farming is waking up every morning and not knowing what challenge you’re going to be faced with. It’s a different day every day, and you don’t know what’s going to happen,” Ochoa says. “I really enjoy working with the people I work with every day. I like seeing other people succeed and create better lives for themselves and their families. I love the fact that we farm this many acres and we can feed so many people off of what we do.”

How to Buy Better Seed Story and photos by Dave Alexander, Publisher

iller Research’s annual potato pest management meeting resumed this February after a pandemic-break in 2021. Held in the historic Wilson Theatre in Rupert, Idaho, the meeting featured speakers Jeff Miller and Trent Taysom from Miller Research and Jonathan Whitworth from USDA. Whitworth, appearing remotely, gave a presentation on seed health to in-person and online attendees. He shared ideas on how to buy better seed, reported on new varieties being bred with disease resistance and spoke of the dangers of Potato virus Y (PVY). PVY can be identified by mosaic leaves, meaning leaves turned green and yellow in a mosaic pattern.

“We know PVY causes yield loss and quality loss, but risk can be reduced by buying seed with low virus readings,” Whitworth said.

Tags vs. Certificates

Buying blue- or yellow-tagged seed does not guarantee a virus-free crop. Colored tags on seed lots do not indicate disease status. Tags are used to indicate size and grade, along with a few restrictions on appearance that can be caused by diseases. Instead, growers should ask for inspection reports or plant health certificates to help inform their certified seed supplier decision. Certificates typically give summer field and winter

grow-out readings. The summer results tell about tuber-borne virus, but the winter readings tell about the currentseason spread of virus. Whitworth said, therefore, the winter inspection gives a better indication of virus level. Valuable information on plant health certificates is often in the “comments” section, which may list all the laboratory tests performed on the seed lot. “It’s okay to ask multiple growers for plant health certificates when you are making your decisions,” Whitworth suggested.

See For Yourself

In their inspections, seed certification agencies make sure there is good

separation between lots in the field during summer inspections and also in storage during post-harvest inspections. These inspections help to maintain identity of seed lots along with the in-field inspections in which inspectors are looking for disease and variety mix issues. Whitworth recommended that commercial growers visit their seed growers. Many commercial growers use the same seed providers year in and year out. But if a grower is buying seed from a new supplier, it helps to see what their operation is like. Attention to detail on seed farms translates into what they supply. As a final thought on seed choice, Whitworth recommended slowing down when making choices and making sure you have all the information available.

Miller’s Thoughts

Jeff Miller gave these recommendations on preventing seed piece decay: •Purchase seed with as little dry rot as possible. •Plant uncut seed, if possible. •Sterilize seed-cutting equipment. •Sharpen seed-cutting knives. •Ensure pre-cut seed is suberized properly or reduce time between cutting and planting. •Use an effective seed treatment. •Avoid planting into cold, wet soil.

Fusarium dry rot is a disease of stored potatoes and also causes seed piece decay in the field. Recent research by Christy Christian and Dr. Kasia Duellman at the University of Idaho has investigated which species of the fungus are responsible for causing dry rot in the Pacific Northwest. The species Fusarium sambucinum, F. oxysporum, F. redolens and F. culmorum were all found to cause dry rot to some degree. This quiz shows symptoms of the four fungal species on both Russet Burbank and Umatilla Russet. Can you determine which species is responsible for the dry rot in the photos below?

Fresh Potato Merchandising Best Practices

By Kayla Dome, Global Marketing Manager for Retail, Potatoes USA

id you know retailers with diverse potatoes sell more potatoes and get a higher everyday price for potatoes? Market research company IRI completed a merchandising best practices study, commissioned by Potatoes USA, to help grocery decision-makers across the country optimize their in-store displays for potatoes. The merchandising study revealed top grocery retailers’ key tactics to optimize their assortment, displays and promotions for continued sales growth post-2020.

Assortment

Having the right types of potatoes and pack sizes on the shelf is the building block for any robust potato set. Consumers commonly know russet, red, yellow and white potatoes. When someone buys one of these four types of potatoes, they already know what to do with them. Russet potatoes make up the

largest share of potato volume sales and are the base of a potato category. Red, yellow and white potatoes are important categories to be on the shelf. Having these four as a base gives consumers what they are looking for and brings them into the potato category. Petite, medley and purple potatoes drive trial and diversity for consumers and higher sales for retailers. Even though these make up a much smaller share, they are key for growth in any potato set. As for pack sizes, the study identified recommendations based on the assortment of top-performing retailers. About two-thirds of fresh potatoes should be made up of bags under 10 pounds, and only 8 percent should be 10-pound bags or greater. The bulk category should make up 24 percent.

Display

Fresh potato shelving comes in four different types: bins, cardboard boxes, vertical shelving and tables. Topperforming retailers are using various types of shelving and are creating unique and interesting potato displays for their consumers. Signage for potatoes is also very important and consists of marketing and price signs. Marketing signs hang above the potato displays, marking the category and helping consumers easily find what they are looking for. The second type of sign is price tags. Consumers will not buy fresh potatoes if they do not know the cost, whether full price or discounted. Utilizing both types of signage, with an even split, leads to growth for topperforming retailers. Too many price signs have the opposite effect on sales.

Promotions

Promotion means more than just discounting a product; it also entails highlighting potato types to attract more consumers. With 76 percent of consumers purchasing full-priced potatoes, promotional dollars can be used more strategically to add growth. Top-performing retailers are using

their promotional discount dollars by highlighting lesser-known potatoes. For example, they are discounting a petite potato slightly, which is drawing in more consumers. When consumers come in for the growth drivers, they also pick up one commonly known potato: russet, red, yellow or white. Thinking about the time of year consumers increase potato purchases also helps better plan discount dollars. Top-performing retailers use discount dollars during months like July when potato sales are lower and highlight them in circulars during the holidays. This reminds consumers about potatoes during the holidays and brings new sales when generally lower. Not only are topperforming retailers selling more potatoes by using promotions in this way, but they are also getting higher average everyday prices.

Incrementality

Incrementality refers to new fresh potato items in various pack sizes that add additional sales to an already highperforming category. The top 10 SKUs adding incremental value to the fresh potato category are all 5-pound bags or less, including petite, red, yellow and russet potatoes. Value-added items are also adding incremental value. Valueadded means potato SKUs that eliminate a step for the end consumer. They are either already seasoned, come in a container that can be cooked in, or do not require additional steps such as chopping. This shows that consumers are looking for diversity with their potatoes and their dishes in home kitchens. Variety and diversity are vital to being a top-performing potato grocery retailer. Knowing how to set up a proper display of potatoes and how to promote them can add additional value to the end consumer and additional sales for retailers.

National Potato Council

Potato Growers Focus on the Future With 2022 Policy Agenda By Kam Quarles, CEO, National Potato Council

uring this year’s Washington Summit, held Feb. 28-March 3, potato growers from across the country joined the National Potato Council (NPC) in Washington D.C. during a tumultuous time for our industry and our country. The impact of inflation on consumer goods and ag inputs, trade disputes with important industry partners, and the war in Ukraine were all on our minds as we sat down to set our policy agenda for 2022. Even with this challenging backdrop, the group focused on a number of proactive policy goals that deliver longterm benefits for our potato farms and the families and communities they support.

Potato Country

May/June 2022

Easing Supply Chain Challenges The U.S. potato industry is dependent upon an efficient transportation system in moving product from the farm through the supply chain to the end consumer. Unfortunately, current supply chain disruptions are creating severe shortages of vital inputs for potato production and inflating prices for those fortunate producers who can secure supply. During the Summit, NPC identified several specific regulatory and legislative actions that could assist in relieving some of the current bottlenecks that are severely impacting producers, including removing burdens on truck drivers and easing the regulatory load of shippers. The U.S. is suffering from a severe lack of qualified commercial truck drivers, which has a disproportionate impact on U.S. agriculture. Exacerbating

this problem are new Biden administration mandates that greatly increase the hourly burden on new drivers to obtain commercial driver’s licenses (CDL). In 2022, NPC will continue to urge the administration to reconsider the unintended consequences of these new regulatory mandates and seek to address safety through less obstructive means. A related effort involves easing restrictions of truck drivers’ Hours-ofService (HOS) regulations, particularly during planting and harvest seasons. NPC is advocating for enhancing HOS rules to acknowledge the unique challenges for transporting perishable commodities and expanding the current 150-mile loading exemption to cover both loading and unloading activities. Truck drivers should not be penalized for encountering delays at loading points or congestion at

distribution warehouses or port facilities. NPC believes that time spent idling in a marshalling yard should not count against HOS mandates. U.S. potato growers are also pushing for Congress to pass the Ocean Shipping Reform Act (OSRA), which is intended to ease the supply chain bottleneck at the ports. The legislation is designed to reduce the burden on shippers who are suffering from supply chain disruptions impacting intermodal freight transiting through commercial seaports. Currently, shippers have to pay daily demurrage charges (or monetary penalties) for containers that are stuck in seaports through no fault of the shipper. This is costing thousands of unnecessary dollars and keeping valuable equipment idle, thereby driving up freight rates due to lowered supply. The NPC-backed OSRA would prohibit these types of burdens and utilize data to avoid future bottlenecks.

Addressing Workforce Challenges

The potato industry is acutely aware of the challenges faced by agriculture to find labor to plant and harvest crops. To address the crisis, last year the House of Representatives passed the NPCsupported bipartisan Farm Workforce Modernization Act – the second time it has passed the bill in consecutive sessions of Congress. NPC and our partners in the Agriculture Workforce Coalition are now encouraging the Senate to improve upon that bill and create the opportunity to secure a long-term fix to this crisis. We believe these improvements should focus on providing U.S. agriculture access to a guest-worker program with the flexibility to meet the current and future demands of American agriculture that includes: (1) a predictable marketbased wage rate, (2) responsive visa terms and no “hard caps” on participation,

and (3) reducing the costs of program participation, among other priorities. Additionally, the Senate should act to stabilize the current improperly documented workforce through a program that incentivizes foreign-born workers to remain in American agriculture. We believe these pieces must be in place before any additional enforcement measures can be implemented. Mandatory E-Verify (alone or with an “agriculture exemption”) would be extremely destructive to our industry and cannot move forward without an ag labor solution. These are just a few of the policy priorities being supported by U.S. potato growers this year.

Say No to Pink Keeping Pink Rot Out of Potatoes

By Jeff Miller, Trent Taysom, Terry Miller, Cheryn Clayton and Scott Anderson; Miller Research Nora Olsen, Lynn Woodell and Rabecka Hendricks; University of Idaho

ink rot, caused by the oomycete pathogen Phytophthora erythroseptica, can cause significant problems in potato production. Pink rot is typically more severe with short rotations and the use of susceptible varieties such as Russet Norkotah and Clearwater Russet. The pink rot pathogen normally infects the potato roots and stolons and then grows into the tuber. Most infections in tubers will originate at the stem end (Fig. 1). This is different from Pythium leak, another disease which can appear similar to pink rot, which usually develops through eyes, lenticels or damaged tissue (like pink eye) in the field (Fig. 1). Pythium infection can occur during the growing season but is more common in storage when infections develop from wounds that occur at harvest.

against MR isolates. Phosphite fungicides are relatively weak and require high rates. In some areas, phytotoxicity results from the use of these products. Oxathiapiprolin has shown high efficacy as an in-furrow application, but maximum residue limit (MRL) issues currently prevent its use on

potatoes destined for export. Cyazofamid and ethaboxam have been more inconsistent in performance compared to the first three fungicides on the list. Phosphite fungicides are relatively weak with respect to the amount of active ingredient needed for disease control.

The infection occurred on the side of the tuber. The infected tissue in cross-section is light to dark gray and is wetter and darker than pink rot. 80

70 60 % Tubers Infected

One of the most effective methods of managing pink rot is to avoid overwatering. The pink rot pathogen infects plant tissue through the production of spores that swim in water. Thus, the longer the soil is wet, the greater the chance for the pathogen to infect. Our research has shown that fungicides are not as effective when a crop is overwatered (Table 1). Research in the Pacific Northwest has shown five classes of fungicides to have some degree of activity against pink rot: •Mefenoxam/metalaxyl (e.g., Ridomil Gold products) •Phosphite (phosphorous acid, phosphonates, e.g., Resist 57, Phostrol) •Oxathiapiprolin (e.g., Orondis Gold) •Cyazofamid (e.g., Ranman) •Ethaboxam (e.g., Elumin) Mefenoxam/metalaxyl products have a long history of efficacy against pink rot. However, isolates resistant to those fungicides (MR isolates) have been found in many areas. Phosphite-based fungicides have proven to be effective

Figure 2. Effect of interval phosphite fungicide application and irrigation on pink rot incidence Figure 2. Effect of between interval between phosphite fungicide application and irrigation on pink rot incidence

Multiple applications of relatively high rates are required for phosphite fungicides to control pink rot infections in potato roots and tubers. Currently, growers are advised to apply up to a total of 30 pints per acre in a season over three to six applications. This has been the most effective approach for varieties that are highly susceptible to pink rot such as Russet Norkotah. The fungicide is taken up by the plant and translocated to the tubers, where it provides protection against pathogen infection.

Field Trials

Field trials were conducted from 2019 to 2020 on Russet Norkotah to evaluate the effect of interval between phosphite fungicide application and irrigation. Treatments included: •Untreated check (no fungicide) •48-hour interval between fungicide application and irrigation •24-hour interval •12-hour interval •6-hour interval Phosphite fungicide (Resist 57, Actagro; 10 pints/A) was applied when

the largest tubers were dime-size (about 15 mm in diameter) and again two more times using a two-week interval between sprays for three total applications. Phosphite fungicide applications significantly reduced pink rot incidence at harvest if the application was made at least 12 hours prior to irrigation. Fungicide applications made only six hours before irrigation offered some protection in 2019 but were not effective in 2020. Application intervals of 24 and 48 hours were no more effective than applications made at 12 hours preirrigation.

Other Considerations

Some consultants indicated that the relatively high temperatures experienced in 2021 in the Pacific Northwest caused growers to increase irrigation. In some cases, portions of potato fields were irrigated less than 12 hours after phosphite application. This may have compromised the performance of the phosphite fungicides. Some growers have used chemigation to apply phosphite fungicides, and

on-farm field trials have shown that chemigation can be effective. Chemigation is typically done using the lowest water volume possible, usually close to 0.15 inches of water. The irrigation amounts after applications in these trials were between 0.57 and 0.76 inches of water. The low volume of water in the chemigation application may be low enough to allow phosphite to be taken up by the plant. Growers have reported that chemigating phosphites does not appear to be as effective as applying by airplane, however. More work needs to be done in this area. When pulp temperatures are above 65 degrees Fahrenheit at harvest, pink rot development increases. Harvesting below 65 degrees will help reduce pink rot in storage. Additionally, post-harvest application of phosphite fungicides is effective in reducing disease development in storage that results from infected and healthy tubers coming in contact with each other.

Most potato fields are full of a wide variety of small winged insects. Some of these are serious plant-feeding pests, some are serious disease vectors, others rarely – if ever – cause damage, and some are either beneficial predators or incidental scavengers. Here are photos of three insects that can be found in potato fields. Only one of them is a pest. Questions: 1. Which photo represents a common pest insect, and what is it? 2. What are the other insects?

Know Your Insects Answers (from page 24)

1. Photo B is the pest; it is a winged green peach aphid, which is a virus vector and capable of direct feeding damage when their populations grow beyond the control of predators, disease and/or insecticides. 2. Photo A is a male fungus gnat of the genus Pnyxia (family Sciaridae). Fungus gnats are common in many habitats from agricultural fields, to potato storages, to the living rooms of houses with many indoor plants. The larvae are scavengers, often found in potato tubers in the early stages of rot. Photo C is a moth fly (family Psychodidae). The larvae of this family are also scavengers. Moth flies are found in many habitats, but some of us are most familiar with them in conjunction with their alternative common name: drain flies. These flies are often found indoors near sinks and toilets where their larvae live in drain pipes.

Market Report

Production Costs, Food Inflation, G

rowers are busy planting the 2022 crop now. Planting decisions may have been more challenging this year than they have been in the past. Production costs are rising rapidly. Inflation is higher than it has been in 40 years. Crop prices have been extremely volatile. There is no shortage of uncertainty going into the 2022 crop year. In this article, we review some of this year’s challenges and opportunities: production costs, food inflation and potato prices for the 2022 marketing year.

Production Costs Continue to Climb

Food Inflation on the Rise

The average U.S. price of food jumped 7.9 percent during the year ending Feb. 28, 2022, according to the U.S. Bureau of Labor Statistics. That is the largest food inflation surge since 1981. During that same timeframe, “food away from home” and “food at home” prices increased by 6.8 percent and 8.6 percent, respectively. Overall, food inflation has averaged 2 percent for the previous decade (20122021). Food inflation projections for the next few years vary widely. The RussiaUkraine war has added a new level of uncertainty to the equation. Typically, one-fourth of the world’s wheat supply comes from the region. Though that wheat does not directly affect U.S. markets, as we have seen recently, it can have a large indirect impact on U.S. and global wheat prices. Higher wheat prices have a ripple effect throughout

the food industry. Rising production costs combined with the disruption in the world’s wheat supply are likely to translate into higher-than-normal food inflation, which could continue for the next several years.

Lessons Learned From the 2021 Marketing Year Figure 1 shows the marketing year fresh weighted average prices (FWA) for russet table potatoes in Idaho, the San Luis Valley, Wisconsin and the Columbia Basin over the past five years. The 2021 prices are preliminary through March 16, 2022 (press time). There are several interesting things to point out with prices for the 2021 crop. First, Idaho and Columbia Basin prices have outpaced San Luis Valley and Wisconsin prices for the first time in modern history. Prices in the Pacific Northwest usually lag behind other areas, partially due to transportation costs. However, prices for the 2021 crop have exceeded those from other areas despite

Nailing down production costs this spring has been like trying to buckle a 2-year-old child into a car seat. This year, the global crop input supply situation has been rattled by inflation and war. Growers have been struggling with rapidly rising production costs for the past two years. Input costs for the 2021 crop increased by approximately 15 percent to 20 percent per acre. Though prices are constantly changing, early estimates indicate that input costs could jump another 18-22 percent or more for the 2022 crop. Prices for fuel, fertilizer, chemicals and repairs have surged. Labor supplies are short, and growers have had to increase wages to keep employees. In addition, rising interest rates will contribute to the overall increases in costs. If 2022 crop yields return to trendline, that could increase total production costs by $0.60

to $2 per cwt. Break-even prices to the grower will take another big jump in 2022.

May/June 2022

Potato Prices skyrocketing transportation costs this year. Strong frozen processing demand for open market russets combined with the region’s smallest potato crop in more than a decade have supported strong prices. Second, prices for the 2021 crop appear to be meeting some resistance at the 2019 price level. Idaho and Columbia Basin shippers have been able to break through that resistance. Though movement from Idaho and the Columbia Basin has been slow this year, the region will likely have little to no carryover from the 2021 crop. Shippers in the San Luis Valley and Wisconsin held back on price increases for the first half of the season. Their marketing year average prices could remain $1 to $2 per cwt below 2019 levels. Shippers will be challenged to increase prices above that resistance level in 2022. Most importantly, the chart illustrates that pricing patterns can be broken. The 2017-2020 price patterns are very similar, though the price range varies from year to year. During that timeframe (and many years before), Idaho prices have been at the bottom, followed by the Columbia Basin. Wisconsin has always held the top spot, with the San Luis Valley not far behind. The typical pricing pattern may return for the 2022 marketing year, but it will need to shift upward if prices are to remain profitable for growers.

Will Potato Prices Keep Up?

Potatoes are a staple item in the American diet. Consumers have become accustomed to potatoes as a relatively inexpensive part of their food purchases. Fresh shippers will likely face some resistance when it comes to increasing prices for the 2022 crop, especially if yields rebound and the industry is challenged to market a much larger crop. The industry will need to make a significant pricing shift upward for the 2022 crop. Nevertheless, if shippers are unable to increase potato prices with general food inflation and rising production costs, growers could receive prices well below breakeven.

KEY POINTS

• Prices will need to increase significantly to cover rapidly rising production costs. • A return to trendline yields could boost U.S. production for the 2022 crop by 5 percent to 8 percent. • Holding prices above production costs could prove to be challenging.

U of I Opens Seed Potato Germplasm Lab

The University of Idaho has opened a new seed potato germplasm laboratory. The facility was built to address demand for disease-free plantlets and mini-tubers, which is greater than current capacity allows. Plans are to increase plant production by three times over the next five years. Increased cold storage capacity allows for greater production of current varieties to meet industry needs while supporting increased development of new varieties. The $5.3 million lab was funded by the Idaho Potato Commission, Northwest Farm Credit Services, the state of Idaho and private donors.

Study Compares Fries to Almonds

A research trial has found no shortterm statistically significant difference between calorie-matched French fries and almonds on key health metrics. Study participants added 300 calories to their daily diet by eating either one-third cup of almonds or a medium serving of French fries each day for a month. The study found that the French fries did not result in differential short-term weight gain or other biomarker changes associated with impaired blood sugar regulation compared to the almonds. The Alliance for Potato Research and Education provided funding for the study but had no influence on the study or data analysis.

PEI Potato Shipments Resume

Canada resumed exporting Prince Edward Island (PEI) table stock potatoes into the U.S. in early April, following the end of a ban resulting from the discovery of potato wart in several PEI fields last fall. Shipments are subject to several mitigation measures, and the ban on seed potatoes from PEI continues. The National Potato Council issued a statement in response to USDA’s announcement that trade of table stock potatoes could resume, noting that organization leaders are dismayed and calling the decision surprising and disappointing. The NPC urges the USDA to “enact science-based mitigation measures that will protect U.S. growers from this highly destructive disease.”

Potato Growers of Washington

Clearing Up Contract Confusion

By Dale Lathim, Potato Growers of Washington

here has been a lot of talk and emotion surrounding the everescalating cost of production for the 2022 crop and the contract price. As this has been happening, there have been some misunderstandings and misinformation about Potato Growers of Washington (PGW), our focus and the profitability of potato contracts. For those who directly asked about some of these issues, we thank you, as it is always good to have checks and balances in place. By walking many growers through this process in one-on-one conversations and at the well-attended all-grower meeting we had, we hope many of you are feeling better about things going forward. For those of you who have not heard the explanations and for those who may want additional perspective, I will try to address once again several of the concerns that have been expressed. To make it very clear, we use weighted averages for all the Columbia Basin potato contracts we negotiate. All quality attributes such as size, specific gravity, color, etc. are done on a weighted average basis by potato variety and delivery type. For instance, we calculate size to be used in the Russet Burbank grower storage contract valuation by weighing only the volume of Russet Burbank potatoes that exceed 6 ounces in weight over the past five crop years delivered on grower storage contracts. The same is done for each attribute, variety and delivery type. Here’s an example to demonstrate weighted average. If 10 growers grow 500 acres of potatoes with a yield of 30 tons/acre and one grower grows 5,000 acres of potatoes with a 42 ton/ acre yield, the straight average yield would be 31.09 tons/acre. But on a weighted average basis, the average would be 36 tons/ acre or the total production from all 10,000 acres divided by the number of acres, not the number of growers. Weighted average is the most equitable way to look at any aspect of a potato contract and is the method that has been used for at least the last 50 years in the Columbia Basin. We do this on profitability, as well. We want the weighted average profit margin to be as close as possible to our targets of 15 percent for out-of-field deliveries and 25 percent on grower storage. We fully recognize that there will always be growers who are above and those who are below the weighted average. But there will always be half of the volume above and below, not necessarily half of the operations above and half below due to their differences in size. Why so many have an issue with using weighted average for yields is very surprising to me. Since we use the same methodology for calculating quality attributes, why is there not as big an uproar over not everyone hitting the specific gravity number or the size profile we use in our contract valuation sheets? There are just as many operations that are either above or below those numbers as there are on yield, yet growers adjust 32

those in their minds when they compare the contracts just like they should with the yields. The push to divide the north basin into a separate bargaining region was done because the yields in the north are not as high as they are in the south. This is true and most likely will always be true. But yield is only one factor in determining the economic return on a potato contract. Quality can often be more valuable than yield, and individual cost of production is the third leg on the profitability stool. Historically, the north basin storage potatoes have been higher quality than those in the south basin. That difference has become much less than in the past, but there is still a gap. On average, storage contracts in the north basin will pay in the neighborhood of $5-6/ton more than the same variety and delivery date in the south, while the overall average yield in the south for storage potatoes is about 5-6 tons/acre more than it is in the north. The added revenue from the higher quality makes up for some of the lesser yield, but the rest is made up in the third factor for profitability, the cost of production. Cost of production is significantly higher in the south basin. In talking with growers, processors and financial institutions, growers will typically spend $600-$800/acre more to grow, harvest, handle and store potatoes in the south basin than they do in the north. The higher costs come in to play with the longer growing season and additional pests which require more crop protectant applications. Larger yields mean more harvest, handling and hauling costs. And the most significant difference is the cost to get the water to the field. In the north basin, water costs are about $30-$60 per acre foot of water and power, while in the south, where they use more water, it is closer to $120/acre foot. In our information gathering, we learned that while yields are lower in the north, the north also has the advantages of lower costs of production and higher quality. In the end, the return for each dollar invested to grow the potato crop returns a higher percentage in the north on the weighted average production of Russet Burbank storage potatoes, which is the highest volume contract type. Other varieties were closer to being equal. But the bottom line was that due to the lower cost and higher quality, all contracts were in line with our projections of hitting our targets for profit margin. We fully understand there are several operations in the north basin that either don’t get the higher quality and/or don’t have the lower costs, resulting in profit margins well below our weighted average. But as a group, we must continue to focus on the weighted averages while each individual operation must focus on addressing the two legs of the profitability stool they can control: the quality they produce and the cost it takes to grow the potatoes. Again, we appreciate the challenge brought forth to help us be certain that the direction we are going is the right one.

Nematode Protection + “Carbamate Kick” = Improved Yields

Vydate® C-LV insecticide/nematicide protects crops systemically by moving above and below ground. In the soil, Vydate C-LV provides protection against damaging nematodes. Above ground, its foliar activity protects plants against numerous insects, such as aphids, lygus, Colorado potato beetle, potato psyllid and leafhoppers. Furthermore, Vydate C-LV offers the well-documented “carbamate kick,” characteristic of its class of chemistry. In the field, this often shows up as “green up” of plants, improved plant vigor/growth, reduced senescence and improved yields.
