  • Fungicide Evaluation for Alternaria Head Rot (Pin Rot) of Broccoli

    Fungicide Evaluation for Alternaria Head Rot (Pin Rot) of Broccoli

    Broccoli head rot, also known as pin rot, can cause significant problems, especially in fall broccoli production in Salinas Valley. Two types of head rot are affecting broccoli, including bacterial head rot and Alternaria head rot (Koike 2010). Differences between those two types can be seen at: https://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=3861. Here we focus on the Alternaria head rot, caused by the fungi Alternaria spp.

    Symptoms. All aboveground parts of broccoli are subject to infection including heads and leaves. Head rot symptoms start as yellow spots and then turn brown and black (photo 1). The infection can spread from buds to stems (photo 2). With secondary bacteria or fungi infection, further decay occurs.The initial yellow spots resemble brown bead (photo 3), a broccoli disorder that can potentially be caused by excessive temperature, poor growth, or nutrient and water deficiency. However, the brown bead doesn’t rot the stem, and no sign of fungi is presented on the buds. For uncertain cases, scraping the buds to see if the stem rot or fungi are presented is a useful technique. Leaf spot symptoms start as small yellow spots on the old leaves and then form dark, concentrical rings like a target (photo 4). The old spots may become brittle and split open or fall out as shot holes. The high number of leaf spots per plant indicates a higher disease pressure and could be a signal for fungicide application.

    Management. The disease is favored by prolonged wetness from rain, dew, and fog. Fungal spores are spread by winds and splashing water. Cultural practices to promote leaf drying or prevent leaf wetness may reduce disease severity. Some growers have seen the benefits of using drip irrigation instead of overhead irrigation. An early harvest before rainfall could also reduce disease risk. Variety effects on disease tolerance might play a role. Lumpy broccoli heads tend to accumulate water which may further weaken the plant tissues and become a suitable target for the pathogens. Finally, there are a number of fungicides that have activity against the disease. More frequent fungicide applications should occur during wet weather which is favored by the disease.

    Research update: fungicide evaluation.

    Methods. One fungicide trial was conducted in a commercial broccoli field to test the efficacy of select fungicides for controlling broccoli head rot in 2023 fall. Broccoli ‘Centennial’ were direct seeded on 27 July, 2023. Seven fungicide treatments and a nontreated control were arranged in a randomized complete block design with four replications. Each plot consisted of two seedlines of broccoli that was 30-ft long on the 40-inch wide bed. On each side of the plot was a nontreated guard bed. Treatments were applied with a CO2-pressurized backpack sprayer calibrated to deliver 35 gpa at 30 psi using a double TeeJet 8004E flat fan nozzles. Fungicide applications were made on 4 October and 16 October. All treatments were applied with non-ionic surfactant Dyne-Amic 0.08% v/v. Alternaria head rot incidence was evaluated at harvest on 23 October, 2023. Disease incidence was expressed as the percentage of the number of plants with Alternaria head rot in the total number of plants within the middle 15 ft of the plot. Data were analyzed using analysis of variance (ANOVA) and the Tukey test to separate means at P<0.05. The total rainfall received one month before harvest was 0.57 inches. The average, minimum, and maximum temperatures were 62°F, 53°F, and 75°F, respectively.

    Results (Table 1). The disease pressure in this trial area was low with nontreated control having 14.0% head rot. However, significant differences occurred among treatments for the % Alternaria head rot. All treatments reduced % Alternaria head rot numerically, while Pydiflumetofen+Fludioxonil, Azoxystrobin, Fluxapyroxad+Pyraclostrobin, Fluopyram+Trifloxystrobin, and Pyraclostrobin had significantly lower % Alternaria head rot than nontreated control. And they had statistically similar % Alternaria head rot. These results also showed that single FRAC 11, premixes with FRAC 7 and 11, and premixes with FRAC 7 and 12 provided good control of Alternaria head rot; single FRAC 7 provided fair control of Alternaria head rot.

  • Australia a Key Market for US Fresh Fruit

    Australia a Key Market for US Fresh Fruit

    Australia is a crucial market for U.S. fresh fruits because of the year-round demand for high-quality products. The U.S. has benefitted from a well-established reputation for producing quality and safe fruits. While demand for fresh fruit was low in Australia from 2018-2020, the fresh fruit industry has recovered, and demand will likely increase for the next five years.

    Strong Market for U.S. Fresh Fruit

    Australia is a well-developed market for fresh produce, including imports. The United States has a good reputation for supplying safe, high-quality produce. A major advantage for Northern Hemisphere growers looking to import into Australia is counter-seasonal growing (see Figure 1).

    Behind New Zealand, whose top exports are avocados and kiwi, the United States is the second largest supplier of fresh fruits to Australia – with 41% of the market in 2022 (see Figure 2).

    The leading fresh fruit imports into Australia from the United States include California table grapes, California stone fruit, citrus, California pomegranates, and California and Pacific Northwest cherries. In 2022, imports of California kiwifruit significantly increased due to Italian kiwifruit being shut out of the market.

    Fruit Consumption Expects to Grow

    Between 2018 and 2020, Australia saw a decrease in fruit consumption. This decrease was due to a drought in 2018 and 2019, limiting the supply. Prices for fresh fruit also increased while the supply was low, which deterred consumers from purchasing. When drought conditions ended in 2021, Australia saw an increase in consumption by 2%. Along with the supply returning, this increase was due to population growth, healthier eating, habits, and demand for convenience. Fresh fruit consumption increased from 2020 through 2022; however, in 2024 it will decrease while gradually increasing in 2025-26. (see Figure 5).

    The Australian Government has funded initiatives to promote healthy eating increasing profits for the fruit industry. Food experts predict that the fresh fruit industry will benefit from changing dietary trends emphasizing fresh fruit consumption. Major supermarkets throughout Australia have also driven the growth in fresh fruit consumption and imports by offering customers a range of fresh produce products throughout the year. Woolworths, one of Australia’s biggest supermarkets, started a “Free Fruit for Kids” campaign. This campaign offers kids free apples, bananas, pears, and mandarins at the grocery store to help build healthy eating habits from an early age. Since the start of the campaign in 2015, over 14,000 tons of free fruit have been consumed by children.

    Australian consumers have seen several trends change in the fresh fruit industry in the last few years. COVID-19 had a significant impact on consumer food purchasing behavior. One of the biggest trends to arise is the growth of online shopping, which wasn’t as prominent in Australia before the pandemic. Consumers are also choosing healthier options due to social influences and spending more time at home.

  • UCCE Tulare County Assists Pathologists in Survey for Decay Fungus in Prunes

    UCCE Tulare County Assists Pathologists in Survey for Decay Fungus in Prunes

    Recently, extensive wood decay-related limb breakages have been reported in commercial prune orchards in the Sacramento Valley, adversely affecting fruit production and limiting the value of salable firewood upon orchard removal. Several fungal genera such as PhellinusRhodoformesSchizophyllumSterumTrametesCeriporia, and Perenoporia have been recognized for wood-decaying activity on California prunes.  Phellinus pomaceus has been the primary organism associated with prune decay symptoms in the Sacramento Valley; however, it is yet unknown whether P. pomaceus is present in southern San Joaquin Valley prune orchards.

    Figure 1: Symptoms of advanced Phellinus pomaceus infection, showing white rot internal decay of heartwood. Scale bars 10 cm.

    Phellinus pomaceus, specific to prunes and other plums, is one of the commonly reported wood-decaying fungi that attack the heartwood (non-functional xylem) of mature trees (Figure 1). It tends to attack the trunk and large-diameter branches, often resulting in broken limbs and the loss of fruit-bearing scaffolds. In fact, older trees are more likely to contain infection by the fungus, and frequent pruning of large branches may increase the probability of infection due to exposure of the internal heartwood. The fungus can be identified based on its fruiting bodies that emerge as conks or shelf-like brackets that are usually hard, woody, and hoof-shaped (Figure 2). Under the right conditions, these fruiting bodies are often perennial and may exhibit a darkened upper surface after several years of development.

    UCCE Tulare County assisted UC Davis researchers from the Department of Plant Pathology in surveying Tulare County prune orchards for presence of P. pomaceus. Laurel Hoffman, a PhD student working under Dave Rizzo, Professor of Plant Pathology, visited our local UCCE Tulare County office, coordinating with Elizabeth Fichtner, UCCE farm advisor, to visit and survey prune orchards for the pathogen. With the assistance of Walter Martinez, Tulare County Ag Technician, and Santosh Bhandari, Assistant Specialist, six local ‘French’ prune orchards were surveyed with data collected on tree canopy status and presence or absence of fruiting bodies associated with decay fungi. Surveyed orchards were all over 15 years old and were in varying states of overall productivity. Samples from putative decay fungi were collected and brought back to UC Davis for genetic sequencing to identify the specimens. A preliminary observation based on the initial survey suggests that the prevalence of putative decay fungi in prune orchards is lower in the southern San Joaquin Valley than in the Sacramento Valley. The presence of P. pomaceus in the southern San Joaquin Valley has not yet been confirmed.

    To date, there are no control measures for management of P. pomaceus. Chemical control strategies are not available for management of this disease. Removal of fruiting bodies may limit sporulation, thus having the potential to slow disease transmission. However, the value of this technique is limited by the ability to remove conks prior to sporulation and conks may be difficult to see, particularly after leaf out. Additionally, if the pathogen is present at a high level in (or near) affected orchards, the removal of conks may not significantly influence the total load of spores at a site. Fruiting body removal would not affect the health of infected trees because they are already colonized by the fungus.

    Most of California’s prunes are sold in the dried fruit market; however, a few orchards are reserved for fresh prune production. After the economic lifespan of prune orchards, trees are removed, generating wood that can either be sold as firewood, or reintroduced to the soil through whole orchard recycling.  Infection with decay fungi such as P. pomaceous may adversely affect fruit production, limit the lifespan of infected trees, and reduce the economic longevity of orchards. — By Santosh Bhandari, Laurel Hoffman & Elizabeth Fichtner, UC Cooperative Extension

  • 2023 UCCE Blackeye Bean Variety Evaluation

    2023 UCCE Blackeye Bean Variety Evaluation

    UC Cooperative extension experts led by Michelle Leinfelder-Miles evaluated blackeye bean varieties in a commercial field in Stanislaus County in 2023. The season began with cool and wet spring conditions, which lasted through the month of June and delayed planting. Seven varieties from the University of California blackeye breeding program were planted on July 7th. The varieties were grown on a Hanford sandy loam, and the soil temperature was approximately 75°F at the time of planting. Each variety was planted across six rows on 30-inch spacing, on a row length of approximately 275 feet. The seeding rate was 40 pounds per acre. This was a non-replicated evaluation due to a limitation in seed; therefore, no statistical analysis is presented.

    The trial was planted in a field of CB46, and fertility and pests were managed by the grower in the same manner as the field. Data are presented in Table 1. Stand counts were made approximately two weeks after planting on July 20th. The stand was assessed as the number of plants per two-foot length. Twelve replicate counts were averaged. We evaluated aphid and lygus damage on September 8th, which were low due to the grower’s management. For lygus, we took 10 sweeps from four locations in each plot and counted the lygus. Data were averaged and are presented as a 10-sweep count. For aphids, we used a rating scale from 0 to 10 that accounted for visible crown damage and aphid incidence. In addition to the in-field assessment of lygus, we also evaluated harvest samples for stings and found that, on average, about 1.2 percent of the beans had lygus damage. No diseases were observed.

    We harvested on November 6th. All six rows of each variety were cut and raked into one windrow. At the time of cutting, the grower observed that CB77 plants were laying flat, but they were laying in such a way that the knives still picked up the plants. The grower also observed that CB74 had an upright growth habit that could potentially make it a variety viable for swather cutting. We evaluated 100-seed weight as a measure of seed size, evaluating five 100-seed samples per variety.

    We would like to thank the cooperating grower, the CA Crop Improvement Association for funding regional trials, and the CA Dry Bean Advisory Board for assistance with statewide research prioritization and assistance with outreach. — Images & Article By Michelle Leinfelder-Miles, UCCE
