  • UCCE Experts Share the Latest in Olive Disease Management

    UC Cooperative Experts shared their latest research findings in olive disease management at the recent Olive Oil Day held by the Olive Oil Commission of California (OOCC) in Stockton.

    Jim Adaskaveg, Professor in the Department of Plant Pathology at UC Riverside joined the meeting by video to present his work on epidemiology and management of olive knot and the evaluation of new fungicides for control of olive leaf spot and Peacock Spot. Dr. Adaskaveg has been working with the OOCC for years and has during this time identified a number of promising products for the control of olive knot. The objective is to have a number of products with different active ingredients/ modes of action so that pathogens are unlikely to develop resistance.

    Since these products are not registered on olives, an important part of his work now is on the regulatory side, seeing these products through the EPA process called IR-4. Unfortunately, one of the promising fungicides for Peacock Spot, Ziram (active ingredient ziram), was suddenly cancelled on all crops in February 2022.

    There are additional products in process, including Syllit (a.i. dodine); a decision is expected in October of this year. There is also a product that was previously rejected, Topsin-M (a.i. thiophanate-methyl), that is now back in consideration. In all there are five new fungicide registrations expected.

    For control of olive knot, a number of products have proven effective in the research. Some of these are GRAS (generally recognized as safe) food additives and some are antibiotics (kasugamycin and oxytetrcycline). In order to increase efficacy and reduce the danger of resistence, the most promising approach apprears to be a mixture of chemicals with different modes of action. The food additives do not require complex approvals but the antibiotics are in IR-4. There have been multiple setbacks, but a decision is now expected in December this year for kasugamycin and in March of 2023 for oxytetracycline.

    Mohammed Nouri, UCCE Orchard Systems Advisor presented an investigation of decline symptoms of super-high-density oil olives in the San Joaquin Valley. There are multiple causes of tree decline in CA, including Verticillium wilt, Botryosphaeria, Pleurostoma, Eutypa lata and freezing temperatures; accurately diagnosing these in the field can be very difficult. Consult your local UCCE office or mnouri@ucanr.edu for guidance regarding sampling.

    Dr. Nouri also spoke about the ongoing challenge of Neofabraea. This disease particularly affects the Arbosana cultivar, causing leaf and twig lesions. The infection primarily occurs in wounds caused by mechanical harvest damage but can also appear as spotting on fruit. Research has shown some control with a few fungicides that are in IR-4 for Peacock spot as well. A final optimistic result from a survey of anthracnose in CA found that this disease is not found in commercial CA orchards. It is unlikely to become a significant problem because of low humidity, dry summers, resistant cultivars and a tendency to harvest early.

  • Water Management Strategies for Hedgerow Olive Orchards in California

    After a year’s hiatus, the Olive Oil Commission of California (OOCC) held its annual Olive Oil Day on March 3, 2022, at the Robert Cabral Agricultural Center in Stockton. The purpose of the Olive Oil Day is to update OOCC members and others in the industry about Commission-funded various research projects and other activities. In keeping with the OOCC’s objective of focusing research projects on areas that will improve returns to olive farmers, the majority of the presentations dealt with olive growing and pest management. 

    Among the many informative presentations shared at the meeting, Giulia Marino, UC Cooperative Extension specialist in orchard systems, gave a report on the “Water management strategies for hedgerow olive orchards in California“. This is a 4-year project that will look at how better irrigation can maximize yields, achieve quality objectives and increase resilience to water restrictions.

    One aspect of this work has focused on better understanding the water needs of CA oil olives. All the basic water research on olives in CA was done on table olives so establishing these basic water needs for CA oil olives is essential.

    The project is using two orchards, one in Corning and one in Stockton. The treatments are a control (the grower’s usual irrigation) and three deficit irrigation regimes beginning at pit hardening (80% ET, 25% ET (x2; one will be modified this year). The trees are being extensively monitored: stem water potential, vegetative growth, fruit size and oil yield and quality, and return bloom.

    Work for the future includes measuring ET and crop coefficient, characterizing phenological stages of the olive, adding a 4th plant-based irrigation treatment and starting to develop an outreach program for better water management.

    A field day to learn more about this research project has been scheduled for June 1 in Stockton—save the date!

  • New Resource for Small Olive Oil Farmers in California

    A new resource for small olive oil farmers and producers who want to know more about voluntary Olive Oil Commission of California (OOCC) membership is now available on the OOCC website. While OOCC membership is not required for producers of less than 5,000 gallons of olive oil per year, they may choose to participate in the OOCC’s mandatory sampling and testing program on a voluntary basis.

    A few years ago, the OOCC Board created a voluntary version of the OOCC’s mandatory sampling and testing program to make it more accessible and affordable for smaller producers. The program is available to any California olive oil producer committed to high quality standards for their product and who wishes to have this quality verified by the California Department of Food and Agriculture (CDFA). 

    This OOCC program is only for 100 percent California olive oil. The benefits to members include: 

    ● OOCC member olive oil is analyzed by a credible, independent laboratory to ensure it meets stringent standards for quality and purity;

    ● Samples are collected and verified by the California Department of Food and Agriculture;

    ● Members who meet the stringent CDFA standards are allowed to use the OOCC logo on their packaging and marketing materials;

    ● A list of OOCC Members in Good Standing, which includes voluntary members, is maintained and published each year; 

    The information packet is available HERE and includes more details about the OOCC program Members in Good Standing and other useful resources to help you make an informed decision. Should you have questions or need additional information, please contact OOCC Executive Director Chris Zanobini by email at chris@agamisi.com or phone at (916) 441-1581.

  • Assembly Bill 535 Supporting California Olive Oil Becomes Law

    Assembly Bill 535 was signed into law by Governor Gavin Newsom last week. The bill, introduced by Assemblymember Ceclia Aguiar-Curry, establishes guidelines for how companies can use the word “California” on olive oil labels and other marketing materials.

    While the OOCC does not have authority to lobby and did not take a position on this bill, the new ruling is critically important to the goals of our organization: ensuring California olive oil is accurately labeled so that customers can have confidence in the quality of California olive oil and all California olive oil is trusted and valued.

    The bill was supported by a group of California olive oil producers who launched a Truth in Labeling informational campaign.

    According to a press release from Assemblymember Aguiar-Curry, consumers associate California produced olive oils with quality and demand has steadily increased over time. This increase in demand has led to companies using the word “California” on labels, even if the product only contains a small percentage of oil from olives actually produced in the state.

    Aguiar-Curry carried the bill because she believes misleading labeling causes confusion among consumers. It also places 100 percent California olive oil farmers and producers at a competitive disadvantage because of the greater regulatory burden and higher costs, and hurts the reputation of California olive oil as a trusted product.

    The guideline for olive oil labeling that Assembly Bill 535 provides consumers with clear and transparent information about the oil they are purchasing. The bill will require companies to disclose the minimum percentage of California olive oil present in their product and in the same size as the word “California” on their product label, packaging and marketing materials.

    The bill does not prohibit or restrict blending oils from different sources and destinations, it only requires the term “California” be used in a way that truthfully and clearly represents the actual amount of California-grown olives used in the product.

    With this bill, supporters hope to strengthen the integrity of California olive oils as a premium and trusted product. — Olive Oil Commission of California
