Phytophthora infections have become more common in pistachio. Alejandro Hernandez covers the biology of this disease, as well as his research on rootstock susceptibility and the efficacy of new fungicides. Please note that some of these fungicides are not registered for use in pistachio.

Fruit removal is a serious issue in table olive production, namely because the fruit are harvested before they are ripe. ACC, an ethylene precursor, has the potential to improve fruit removal (please note that the commercial product is not registered in olives yet and cannot legally be used). Becky Wheeler-Dykes, an advisor in Glenn, Colusa, and Tehama Counties, has been examining its efficacy in olives with a team of researchers at UC Davis. She shares some preliminary, and promising results in this week’s episode.

Anyone who has an irrigation system knows that it needs to be maintained for peak performance. Anyone who has an irrigation system also knows that almost everything seems to be more important in the moment than flushing those lines or checking pressures. A distribution uniformity test is a good way to assess the health of your irrigation system, but it isn’t always easy to figure out if the cost of making these fixes, particularly big fixes, will pencil out. CURES got a grant a few years back to develop a tool to estimate the return on investment for making fixes to a system. Inge Bisconer and Parry Klassen share how the tool works and what spurred them to develop it in this week’s episode.

Polyphenol deposition in pistachio kernels, also known as internal kernel discoloration, is a harmless phenotype of pistachios, where dark coloration appears on the internal surface of the pistachio cotyledons (the two halves of the kernel). It started showing up widely in the late 2010s/early 2020s, and researchers Georgia Drakakaki, Phoebe Gordon, and Minmin Wang have been investigating it from different angles (Phoebe from the field perspective; Georgia and Minmin from the anatomical and physiochemical perspective). In this episode, they share some initial results. We still don’t know what truly causes it, but we have some answers to basic questions.

Almond production creates a lot of byproduct. While there are some alternative uses for almond hulls and shells, like livestock feed and bedding, there is still not enough demand to utilize all the biomass created every year. Some growers have been accepting almond hulls and shells from processors to help them get rid of these stockpiles, and using them as mulch in orchards. Ellie Andrews examined how using hulls and shells benefits almond orchards, including their potential as potassium fertilizer, and how they affect soil health.

Today on the podcast we’ll be discussing Red Leaf Blotch a new invasive disease in California almond production. I want to offer my sincere apologies to listeners and to the Trouillas Lab for not getting this episode out promptly for maximum usefulness in the 2026 season. Although we are still in the red leaf blotch susceptibility window at the time of podcast airing – there’s not currently any rain in the forecast. Disease management The disease has a long latent period of 35 to 40 days, so by the time symptoms are visible, the infection window has long passed. This makes early, preventive management the key to controlling the disease. Based on 2025 field trials and growers’ experience in Spain, a three-spray program is recommended for orchards at risk. The first spray should be applied at petal fall (young leaflet emergence), followed by a second application two to three weeks later, and a third spray five to six weeks after petal fall if wet weather continues. These timings coincide with elevated inoculum levels of P. amygdalinum in orchards and a period of high leaf susceptibility to RLB. Similar timings for fungicide applications are used to manage other spring diseases like scab, shot hole, rust, and anthracnose, highlighting the need for an integrated approach to disease management in almond orchards. Research trials in 2025 indicated that the most effective products to control RLB included various mixed fungicides with FRAC groups 3 + 7 (e.g. difenoconazole + pydiflumetofen); 3 + 11 (e.g. difenoconazole + azoxystrobin or tebucnonazole + tryfloxystrobin); 7 + 11 (e.g. fluopyram + trifloxystrobin, fluxapyroxad + pyraclostrobin, or boscalid + pyraclostrobin); 7 + 12 (adepidyn + fludioxonil), and FRAC 3-triazoles (metconazole or flutriafol). Growers are advised to rotate modes of action and follow all resistance management and product label guidelines to prevent product failure over time. Cultural practices, focused on eliminating the primary inoculum of infected fallen leaves, also can help mitigate the disease. These consist of removing leaf litter or applying urea to accelerate its decomposition. However, such strategies are only effective when applied over a wide area. Fungicides applied during bloom and after symptoms are visible are not effective. 2025 Fungicides, Bactericides, Biocontrols, and Natural Products for Deciduous Tree Fruit and Nut, Citrus, Strawberry, and Vine Crops in California Mention of a pesticide does not constitute a pesticide recommendation, merely the sharing of research results.

The pistachio hull is critical for protecting the kernel. Insect pests can’t get through it until it begins to break down. However, it is known that hull integrity can change across years - some years hulls stay intact until harvest, and in other years it begins to break down earlier. Shuxiao Zhang, who used to be a student at UC Davis and is now working as a postdoctoral scholar at Stanford, and Georgia Drakakaki, a professor of plant sciences at UC Davis, decided to look into this. They were able to figure out the processes that led to hull degradation, the different ways degradation occur, and they were able to link in-field conditions to hull split. The Drakakaki lab has been doing extensive research into pistachio fruit development - Phoebe has interviewed the both of them on pistachio shell split in a previous episode.

Phoebe sits down with Elizabeth Fichtner to discuss the biology of pistachio bloom, how it impacts orchard design, and why picking the correct male pollinator is so important. She also goes over the research on artificial pollination of pistachio and why it may only be useful in very specific circumstances. In this episode, Elizabeth mentions that dust can cause parthenocarpy in pistachios; we posted an episode on this a few years ago.
