Firewood borne diseases and pests can cause devastating damage to trees and huge financial losses to growers and the agricultural community. The simple yet important act of keeping firewood purchases local and not transporting to public areas can help prevent invasive pests such as the Asian Citrus Psyllid (ACP), gold spotted oak borer, emerald ash borer and others from gaining a foothold in your community.
For more useful information about this important effort, visit the California Firewood Task Force website. The Farm Bureau Pest Issues webpage has a list of invasive pests and diseases that could threaten Ventura County. Also check out a special presentation on ACP at the UCCE ACP Workshop webpage.

The event was sponsored by the Santa Barbara County Flower and Nursery Growers Association and included a barbeque lunch as part of the registration fees.
The workshop was designed to assist greenhouse and nursery growers evaluate their water quality management practices (BMPs) and implement an Integrated Pest Management (IPM) Program. Information was provided to assist growers in conducting a self-audit of current water quality management practices, developing a farm water quality plan and implementing an IPM program to reduce impacts on water quality.
UC and ANR manuals and resources were used to supplement the presentations. Continuous education credits were also requested for participants.
For more information please visit the AG Water Quality Program webpage or view the workshop PowerPoint presentation here.

California farms produce 93% of the celery grown in the United States. The crop thrives in coastal California’s moderate climate. Celery is an important crop in Ventura County with 40% of the state’s acreage farmed here. Valued at over $182 million, it was the second most profitable crop for Ventura County agricultural producers in 2010, which are the most recent statistics available.
Most celery in the field is planted as transplants. Transplants are typically grown under high humidity and high plant density conditions and are subject to seedborne pathogens. The most significant being Septoria apiicola (the causal agent of Septoria late blight) and Pseudomonas syringae pv. apii (the causal agent of bacterial blight). These diseases can be carried from the transplants into the field. As the plants mature, these diseases can cause plants to become unmarketable at a great loss to the growers.
UCCE’s Oleg Daugovish and collaborators researched these pathogens and how to best reduce disease and loss in the field. Over four years, the researchers documented that: seed, seedlings, weeds located in or near fields that harbor the virus can cause the disease in celery. This disease is likely transmitted by aphids, vectoring the virus.
The studies provided practices growers can use to manage this disease. Findings indicated that growers can control the pathogens by managing poison hemlock weed populations, controlling aphids, and planting celery cultivars that are not susceptible to the pathogens.
The interpretive and technical summaries of the research report can be viewed on this page of the USDA’s Agricultural Research Service. The full text can be accessed through the American Phytopathological Society, or at the UCCE office in Ventura County.
