Spanish-language Training Opportunity for Field Crews
The Citrus Pest and Disease Prevention Program is hosting three free training workshops for field crew supervisors and farm labor contractors in San Diego, Ventura and Tulare counties this month. The training workshops will be in presented in Spanish and will review best practices for field crews on how they can properly prevent the spread of Asian citrus psyllids (ACP) with a hands-on training opportunity.
The Train-the-Trainer workshops will each be a half-day in length and will take place on the following dates:
- Monday, August 21 at 10 a.m. – Escondido, San Diego County
- Tuesday, August 22 at 10 a.m. – Limoneira Co, Santa Paula, Ventura County
- Thursday, August 24 at 8 a.m. – Exeter, Tulare County
The training workshops will also fulfill the requirement listed in CDFA's harvesters/farm labor contractors' compliance agreement for these industry members to stay abreast of ACP and Huanglongbing (HLB) prevention best practices. In addition, compliance agreements will be available at the training workshops.
RSVPs are strongly encouraged. Location details, workshop start times and additional information will be sent upon RSVP. Please RSVP using the following link below.
Front-line leaders in the field will be able to learn firsthand about what they can do to reduce the risk of spreading ACP, and ultimately how to protect local groves from HLB.
During the workshop, participants will:
- Learn best practices for field crews to prevent ACP from spreading in between neighboring groves.
- Practice using effective communication techniques to help their crews and others understand these best practices and why they are important.
- Understand the threat of HLB to the livelihood of the California citrus industry.
We all must do our part if we're going to protect California citrus from this pest and disease – and field crews are at the forefront. Packinghouses are encouraged to send their staff and crews to this valuable workshop as a way to provide an extra layer of protection in preventing the spread of ACP in their groves.

Agéndela: Oportunidad de capacitación en español para equipos de campo
El Programa de Prevención contra las Plagas y las Enfermedades de los Cítricos organiza este mes tres talleres gratuitos de capacitación para los supervisores de los equipos de campo y contratistas de trabajo agrícola en los condados de San Diego, de Ventura y de Tulare. Los talleres se presentarán en español, repasarán las mejores prácticas para los equipos de campo con respecto a la prevención adecuada de la propagación del psílido asiático de los cítricos (PAC) y brindarán la oportunidad de una capacitación práctica.
Cada Taller de Capacitación para el Instructor durará medio día en las siguientes fechas:
- Lunes, 21 de agosto a las 10:00 a. m. – Escondido, condado de San Diego
- Martes, 22 de agosto – Santa Paula, condado de Ventura (luego se decidirá el horario)
- Jueves, 24 de agosto – Exeter, condado de Tulare (luego se decidirá el horario)
Se recomienda que reserve su lugar. El lugar y el horario de los talleres, así como información adicional se le enviará en cuanto reserve. Hágalo en el enlace siguiente.
Los líderes principales del campo podrán aprender de primera mano lo que pueden hacer para disminuir el riesgo de la propagación del PAC y, fundamentalmente, cómo proteger los huertos locales de la Huanglongbing (HLB).
Durante el taller, los participantes podrán:
- Aprender las mejores prácticas para los equipos de campo para prevenir que el PAC se propague entre los huertos vecinos.
- Ensayar el uso de técnicas efectivas de comunicación para ayudar a sus equipos y a otros a entender las mejores prácticas y su importancia.
- Entender la amenaza de la HLB a la subsistencia de la industria californiana de los cítricos.
Todos debemos poner de nuestra parte para proteger a los cítricos de California de esta plaga y enfermedad, y los equipos de campo están en la vanguardia. Se recomienda que las plantas empacadoras envíen a su personal y a sus equipos a este valioso taller para brindar una capa extra de protección a la prevención de la propagación del PAC en sus huertos.

SANTA BARBARA COUNTY CITRUS UPDATES
Save the Date! Santa Barbara County Citrus Meeting
Thursday, June 15, 9 am - 12 pm, at the County Employee University Building, 267 Camino del Remedio, Santa Barbara
Intended for citrus growers, PAC/QAC/QAL/PCA holders, and farm labor contractors in Santa Barbara County. Topics include updates on ACP/ HLB treatments & research, regulatory updates on HLB and other citrus pests, and an update from the new County Ag Commissioner, Jose Chang. DPR CEUs have been requested. RSVP to firstname.lastname@example.org, or call 805 681-5600 for more information.
Asian Citrus Psyllid Update
The next ACP Area Wide Management treatment window for growers will be September 3 - 23. In the meantime, please continue to regularly monitor new flush for signs of the psyllid, and consult with your pest management professional if ACP is present. Tender new citrus flush is ideal habitat for ACP to feed, lay eggs and build new populations, and an increase in ACP numbers and feeding can increase the risk of HLB. If your citrus is no longer being cared for or is not worth the resources required to protect it from ACP and HLB, consider removing it.
HLB Quarantine Update
As of May 26, a total of 5.115 trees and 709 ACP have been confirmed positive for the bacterium that causes HLB. Trees confirmed positive are treated for ACP and removed, and the HLB quarantine may be expanded. Additional ACP treatments and HLB detection surveys are conducted on a recurring basis to remaining citrus within 250 meters of each detection.
Counties where HLB has been detected via PCR testing are Los Angeles, Orange, San Diego, Riverside, San Bernardino and San Diego, with the majority of detections in Orange County. To see a map of the current HLB quarantine areas, and other details of locations and numbers of HLB detections, please visit maps.cdfa.ca.gov/WeeklyACPMaps/HLBWeb/HLB_Treatments.pdf.
HLB Detection Response Guide for Growers
To ensure California citrus growers are well prepared in the event of a potential commercial grove detection of Huanglongbing (HLB), the Citrus Pest and Disease Prevention Program (CPDPP) has developed the Response Guide for a Confirmed HLB Positive Detection in a Commercial Grove, which details the steps taken by CDFA and actions required of the property or grove owner, as outlined in CDFA's Action Plan and Information for Citrus Growers/Grove Managers.

The Asian Citrus Psyllid (ACP) is a small, aphid-sized insect that poses a serious threat to California's citrus trees. This invasive pest can carry and transmit a fatal bacterial disease called Huanglongbing (HLB) to all citrus species. HLB has already decimated citrus groves throughout Florida, costing the citrus industry millions of dollars. The psyllid is currently present in Southern California, but preventative measures can keep the disease and insect from spreading to California's citrus growing regions.
What does the Asian citrus psyllid look like?
Asian citrus psyllid adults are 1/6 to 1/8 inch long with brown wings and red eyes. They feed on plants at a 45-degree angle, with their heads down and back end in the air, unlike any other citrus pest. Their feeding causes twisted or distorted leaves. Nymphs are wingless, flattened, orange to brownish, and are generally found on young leaves and shoots. Both adults and nymphs feed on plant sap and excrete honeydew, but nymphs produce distinct waxy tubules to help clear the sugary waste from their bodies.
What are the symptoms of Huanglongbing disease?
An early symptom of HLB is irregular yellowing of leaves, on an individual limb or in one sector of a tree's canopy. Yellowed leaves are blotchy or mottled, but not symmetrically yellow like a nutrient deficiency. As the disease progresses, the fruit will become smaller, more bitter, and may not ripen properly. Once trees are infected, it may take up to two years for obvious symptoms to occur and trees can die within 5-10 years.
What can you do about the Asian citrus psyllid and Huanglongbing disease?
It is estimated that 6 out of every 10 California residences have at least one citrus tree on the property. Inspecting your own citrus trees is vital to prevent the spread of ACP and HLB. Check your citrus trees for the Asian citrus psyllid, especially in spring and fall when new growth is abundant. If you think you have found ACP or suspect HLB infection, contact the CDFA Exotic Pest Hotline at 1-800-491-1899 or your local county agricultural commissioner.
