  • September Orchard Tasks – Almonds

    Although almond harvest may be wrapping up, the work needed to prepare orchards for next season has already begun. Post-harvest priorities include monitoring for disease, irrigating trees, pruning and managing pests.

    Brent Holtz with the University of California Cooperative Extension advises growers to watch for red leaf blotch and rust. Bright orange spots on leaves may indicate red leaf blotch, while orange and black spores can be signs of rust. This year’s warm March appears to have increased the severity of rust, making it important to avoid irrigation practices that keep orchards humid for extended periods.

    However, growers should not stop irrigating altogether. Water should be applied as soon as the harvested nuts are removed from the orchard floor. Dr. David Goldhamer, emeritus irrigation specialist with UC Davis, says almond trees can use up to 11 acre-inches of water after harvest if their leaves remain active. Proper post-harvest irrigation can also help move salt below the trees’ root zone.

    Growers can also begin pruning mature orchards immediately after harvest instead of waiting until dormancy. Pruning early gives wounds time to heal before rainfall, reducing the risk of fungal diseases. While studies indicate pruning does not significantly improve almond yields, it remains necessary to provide enough space for orchard equipment to pass between trees.

    Fall is also a good time to manage gophers, ground squirrels and mice. Baiting or fumigation can help control ground squirrels before they enter hibernation. Growers should also look for pieces of almond shells left in tree crotches, which may indicate mouse activity.

  • Almond Market Looks Strong Going Into 2027

    The almond industry is entering the new crop year from a solid position according to a recent market update from Blue Diamond Growers. This is thanks in no small part to exports to India.

    The 470.7-million-pound carry-in (of which only 447.1 million pounds is estimated as edible) is down from prior year and confirms the tightness in supply from one crop to the next. Downward pressure on crop potential and overall supply and demand fundamentals continue to support a stable-to-firm market outlook. Export demand remains healthy with the coming weeks expected to provide clarity on crop size, kernel sizing, and the degree to which rapidly appreciated pricing can be absorbed by end markets.

    The 2026 crop year started on a positive note, meeting strong industry expectations. August shipments totaled 190 million pounds. Exports reached 143.2 million pounds, an increase of 31%, while the domestic market shipped 46.8 million pounds at a modest -3.3% decrease versus last year. With six of the last seven last months’ total shipments outpacing previous year, the industry continues to experience strength in global demand.

    India was the clear standout in August, receiving 44.3 million pounds, up approximately 170% from 16.4 million pounds last year. The increase reflects stronger replenishment ahead of the festival season and a normalization from the unusually low August 2025 shipment level. The magnitude of the increase is notable given elevated pricing and confirms India’s continued importance as the primary outlet for California inshell almonds. Local consumption will become increasingly important ahead of festival season as buyers will begin to replenish stocks that dwindled at the end of the 2025 crop year.

    August domestic shipments totaled 46.8 million pounds, down 3.3% year over year. While this may not have been the start to the year the industry had hoped for, the improvement in shipment performance over the last six months provides optimism that the market has stabilized. As prices rose over the last month, purchasing activity slowed and shifted to closer, strategic locations. This cautious approach is expected to continue. Looking ahead, domestic demand is expected to remain steady, with a pipeline of commitments providing support for shipments in the next few months.

    The 2026 crop is progressing rapidly with current receipts for August coming in at 401.9 million pounds. The pacing of receipts is 55% above August 2025 due to harvest beginning approximately 2 weeks earlier than prior year. The increase in receipts over last year is not a reflection of projected crop receipts for 2026.
    Nonpareil and Independence varieties are largely harvested with pollinizer varieties following closely behind. In some of the most advanced areas, growers have completed orchard harvest activities and are focusing on post-harvest practices and minimizing water stress to support next season’s crop.

    Current Nonpareil reject levels are the lowest in several years, though ticking up slightly, driven by a third flight of navel orangeworm. Independence rejects are trending higher than last year, mainly due to brown spot from leaf-footed plant bugs.

    Yields are variable in Nonpareil and Independence depending on the region. Speculation on smaller kernel sizes coming into harvest are beginning to be realized. Yields in Nonpareil and Independence receipts are signaling a lower 2026 crop than 2025, as forecasted. There is continued downward pressure on crop potential, which will be informed by pollinizer varieties that hullers are beginning to process. Next month’s report may reflect further shifts to the forecast as pollinizer volume comes in and is accounted for. — Story contributed by Blue Diamond Growers

  • The Essential Role Post Harvest Nutrition Plays in Future Yield and Quality

  • New Investment Aims to Give Growers Another Tool for NOW

    California almond growers know the challenge navel orangeworm brings every season. The pest can reduce crop quality, increase production costs and raise concerns around aflatoxin and marketability. Now, new additional funding is helping continue an industry-backed research effort to advance another tool growers may one day be able to use as part of an integrated pest management program.

    The Foundation for Food & Agriculture Research, the Almond Board of California and Flyttr™ partnered on a nearly $5 million grant to advance development of a biological approach targeting navel orangeworm in almonds and pistachios. ABC is helping fund a portion of the project, reflecting the almond industry’s continued investment in research that supports long-term orchard productivity, crop quality and grower profitability.

    The project centers on Flyttr’s Friendly™ navel orangeworm technology. The concept is simple: release Friendly™ male moths into areas with pest pressure. When those males mate with wild females, no surviving offspring are produced. With continued releases over time, the goal is to reduce the pest population and lower damage pressure in orchards.

    For growers, the significance is not that this replaces today’s best practices. Sanitation, monitoring, mating disruption, timely harvest and well-timed treatments remain important parts of navel orangeworm management. Instead, this research is focused on developing a targeted biological tool that could complement existing programs and help reduce reliance on conventional insecticides over time.

    Navel orangeworm remains one of the costliest pests facing California tree nuts, with industry losses estimated at more than $800 million each year. Damage can affect yield, quality and food safety, which is why the pest continues to be a priority for research, industry collaboration and new technology development.

    Funding from FFAR and industry partners will support the continued work needed to move the technology closer to practical use, including large-scale production systems and field studies. That means the effort is still in development, but it represents an important step toward expanding the number of durable tools available to growers managing navel orangeworm pressure.

    ABC’s role in helping fund this work is part of a broader commitment to support practical, science-based solutions for almond growers. By investing alongside partners, the almond industry is helping advance research that could protect crop value, strengthen pest management options and support the long-term competitiveness of California almonds.

  • Start With the Conversation That Determines Your Orchard’s Future

    Planting an almond orchard has never been a simple decision. But in today’s margin-tight environment, the choice of rootstock and variety combination is more than an agronomic preference — it is a 20- to 25-year business decision that can shape profitability, harvest efficiency, marketability and long-term risk.

    That was the focus of a grower-facing discussion moderated by Almond Board of California’s Michael Roots, with perspectives from Dave Phippen of Travaille and Phippen, Duarte Nursery’s John Arellano and grower Brandon Ribiero, at the 2026 Almond Crack Out event.

    For growers, the main message was clear. Do not make a planting decision in isolation. A new orchard should begin with a practical, sometimes uncomfortable, conversation about water, soil, rootstock, variety, harvest timing, market demand and, most importantly, economics.

    “Know Your Breakeven Cost Per Pound”

    Ribiero put the economics plainly when he said growers should “know your breakeven cost per pound.”

    That calculation should sit at the center of every planting conversation. Ribiero described it as a simple equation of cost divided by yield. If a grower expects production costs of $3,500 per acre and assumes 2,500 pounds per acre, the breakeven is about $1.40 per pound. If debt, land costs or other obligations push total costs to $4,500 per acre at the same yield, that breakeven rises to $1.80 per pound.

    That difference matters. In a market where prices can move quickly and margins can narrow, the wrong yield assumption, or the wrong rootstock and variety combination for a site, can make an orchard difficult to carry through the low points of the price cycle.

    Ribiero also warned that growers cannot always “save their way to prosperity.” Trimming some costs may help at the margins, but yield is often what moves the breakeven number in a meaningful way. That makes variety performance, rootstock fit and realistic production expectations central to the decision.

    Start With Water, Soil and Site Limitations

    Before selecting a variety, Ribiero said growers should first understand “all things water” — supply, quality and rights. Without water, he noted, the rest of the planting plan loses its foundation.

    From there, the conversation moves to soil. The right rootstock depends on what the site needs most, including vigor, anchorage, salt tolerance, disease resistance, replant tolerance or other characteristics. Prior Almond Board coverage of rootstock selection has emphasized the same point. Growers should identify a site’s limitations first, then select a rootstock that helps address the biggest risks.

    That means soil tests, water quality information, local grower experience and advisor input should all be part of the planning process. Once trees are planted, growers can adjust irrigation and fertility programs, but they cannot easily redo rootstock selection, variety choice or pre-plant soil preparation.

    Bring the Right People Into the Conversation Early

    Roots framed the panel around a gap that often appears in orchard planning. Growers may talk with a nursery early, but the handler is sometimes brought in after planting decisions are already made, or never at all. The panelists encouraged growers to widen the conversation before committing to trees.

    That group should include the nursery, handler, pest control adviser, neighboring growers and other trusted advisors who understand the region. Arellano said a nursery representative should be prepared to answer questions across rootstock, variety, fit for the site and how the planting will work operationally. If he does not have an answer, he said, the next step is finding someone who does.

    Ribiero said he often asks similar questions of different people one-on-one, looking for patterns in the answers. Where the advice is consistent, growers gain confidence. Where there are outliers, that is where the next question should be asked.

    Marketability Should Not Be an Afterthought

    Phippen brought the handler perspective into sharp focus. A variety may look attractive on paper, and a nursery may be able to supply the trees, but the buying public ultimately determines how that almond is valued. Market classification, quality expectations, defects, customer preferences and regional demand all matter.

    For Phippen, that means the marketing team should be part of the decision-making process. They can help growers understand what is moving well, what may be oversupplied and what buyers are asking for. A grower may be able to produce a variety, but the better question is whether the market wants it, and at what price.

    That conversation is especially important because handlers may serve different customers and markets. Quality tolerance, product form, timing and buyer preference can vary. A variety that fits one handler’s program may not be the right fit for another.

    Do Not Overcomplicate the Orchard

    One of Ribiero’s lessons from experience was the value of simplicity. He described a planting with multiple varieties intended to hedge risk around bloom, pollination and market movement. In practice, that complexity created harvest inefficiency without delivering a better return.

    His takeaway for growers was direct. Do not overthink it. A planting plan that is efficient, repeatable and well-matched to the site may provide more long-term value than one built around too many assumptions. Simplicity can reduce operational headaches and make it easier to scale what works.

    Pre-Plant Work Is the Last Chance to Get Some Things Right

    The panel also emphasized the importance of pre-plant groundwork and amendments. Ribiero noted that once an orchard is planted, it is difficult to incorporate materials into the active root zone. If a site needs amendments such as lime, gypsum, sulfur or compost, pre-plant is often the best opportunity to get them where they need to be.

    That point ties directly back to economics. A grower may be tempted to trim development costs up front, but those savings can become expensive if poor preparation limits tree performance for the life of the orchard.

    A Grower’s Pre-Planting Checklist

    • Calculate your breakeven cost per pound using realistic cost and yield assumptions.
    • Confirm water supply, water quality and water rights before moving deeper into planning.
    • Match rootstock to soil conditions, site limitations and long-term orchard goals.
    • Ask your handler how the variety fits current and future market needs.
    • Talk with neighboring growers who have experience with similar soils, water and varieties.
    • Include your PCA, nursery representative, handler and trusted advisors early.
    • Review independent field data and regional trial information where available.
    • Keep the orchard design practical for harvest timing, equipment and labor efficiency.
    • Complete needed soil preparation and amendments before planting.

    The Bottom Line

    Choosing an almond rootstock and variety combination is not just a horticultural decision. It is a business plan, a risk-management strategy and a long-term commitment to a specific site. The most successful planting decisions begin before the nursery order is placed, with honest conversations about what the orchard must produce, what the market will reward and what the grower can afford.

    For growers considering a new planting, Ribiero’s advice is a practical place to start. Know your breakeven cost per pound. From there, every other decision — water, soil, rootstock, variety, marketability and orchard design — should help answer one question. Can this orchard make money through the full price cycle? — Story Contributed by the Almond Board of California

  • Precision Timing Critical for Managing Hull Rot

    With this season’s hull rot treatment window now behind growers, recent research shared by UCCE advisors offers timely guidance for evaluating disease pressure this year and planning more precise management decisions next season. Hull rot remains one of the more frustrating and yield-limiting diseases in California almonds, particularly because its full impact is not always visible in the year it occurs. The research is helping clarify where growers should focus their efforts, especially as the disease complex evolves and growing conditions continue to favor new pathogens.

    Mohammad Yaghmour, orchard systems advisor in Kern County, has been closely tracking changes in the organisms responsible for hull rot. While the disease has long been associated with Rhizopus stolonifer and Monilinia species, the increasing presence of Aspergillus niger is shifting both how the disease develops and how it needs to be managed in the orchard.

    Hull rot follows a classic disease triangle, requiring a susceptible host, a pathogen, and the right environmental conditions. What makes this disease particularly challenging is that all three components are often present at hull split, when almonds are physiologically vulnerable and environmental conditions can favor fungal growth. Infection begins in the hull, but the most damaging effects appear later as the fungus moves into the fruiting wood. Leaves surrounding infected nuts dry rapidly, and the spurs that would produce next year’s crop are killed. In severe cases, entire shoots can be lost.

    This delayed impact is critical. Yield losses are not just tied to visible infection but to the loss of next year’s bearing wood. Research conducted across multiple orchards showed that yield reductions become meaningful once strike levels reach roughly one hundred per tree. At that point, the cumulative loss of spurs begins to reduce the productive capacity of the tree in the following season.

    One of the most important takeaways from this work is that not all hull rot is the same. Each pathogen behaves differently and requires different management timing. Monilinia, which also causes brown rot during bloom, infects earlier and must be managed weeks before hull split. In contrast, both Rhizopus and Aspergillusare primarily driven by inoculum originating in the soil, and infections occur at or shortly after hull split.

    The rise of Aspergillus niger is particularly important for growers in warmer production areas. This pathogen thrives under higher temperatures and has become increasingly common in Kern County before spreading more broadly across the Central Valley. Its symptoms differ subtly from those of Rhizopus. Instead of the gray, fuzzy growth commonly associated with Rhizopus, Aspergillus produces darker, flatter, jet-black spores. It can also lead to internal damage, including black streaking in wood due to toxin production, which contributes to spur and shoot death.

    Understanding when infection occurs has helped refine management recommendations. Research shows that almonds are most susceptible during early hull opening, particularly when the split is still narrow. That window—when the hull has just begun to open—is where infection severity is often highest for Aspergillus. This underscores why spray timing is so critical. Missing that narrow window can significantly reduce the effectiveness of control measures.

    Variety also plays a role. Nonpareil, Butte, and Sonora have shown higher susceptibility, while Monterey and Fritz tend to be less affected under similar conditions. In mixed plantings, this means growers should expect greater risk in Nonpareil blocks and manage accordingly, prioritizing inputs where the return on protection is highest.

    Cultural practices continue to play an essential role in reducing disease pressure. Excess nitrogen has been shown to increase susceptibility, likely by promoting lush growth that favors infection. Careful nitrogen management can reduce that risk. You can learn more about nitrogen management at Almonds.org/NutrientManagement. Similarly, irrigation practices influence disease development. Strategic deficit irrigation has been linked to reduced incidence of Rhizopus, while excessive soil moisture during hull split can increase disease pressure.

    Dust management is another overlooked but important factor. Because Aspergillus and Rhizopus originate in the soil, any activity that creates dust can move spores into the canopy. Equipment traffic during hull split can unintentionally increase inoculum pressure at the exact time tissues are most vulnerable. Reducing dust during this period can help limit infection.

    Fungicides remain a valuable tool, but they are not a standalone solution. Their effectiveness depends heavily on correct timing and proper pathogen identification. Materials in several FRAC groups have shown strong performance when applied at the early stages of hull split. However, applying them too early or too late significantly reduces their value. In most cases, hull split sprays for disease management can be aligned with navel orangeworm treatments, helping to streamline operations.

    For growers, the message is clear: while the opportunity for in-season treatment may have passed, hull rot management is less about any single treatment and more about matching the right tool to the right moment. By using this season’s observations to scout for disease pressure, identify the pathogen involved and plan ahead for precise spray timing, balanced nitrogen, careful irrigation and dust reduction, growers can better protect the fruiting wood that supports next year’s crop and build more resilient orchard systems over time. — Story contributed by the Almond Board of California
