UC ANR’s Spanish News Service website brings Agriculture and Natural Resource information to California residents who are fluent, and more comfortable learning, in Spanish. This is a vital service for all Californians as many of the issues and challenges we face together can only be solved by all of us working together.
This highly organized, visually appealing, and easy to navigate site provides a great deal of information on many important topics. The information can be accessed by audio, video, articles, and blogs.
Topics include:
- Invasive species
- Water quality
- Nutrition and fitness
- Child development
- Preventing obesity and overweight
- Reducing the risk of diabetes
- Natural resources
- Recovering from a natural disaster
- Integrated Pest Management (IPM)
- Preventing and recovering from wildfires
- Money management
- Gardening
- And much more

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.

There are a large number of wasp species in California. Only a few species live a social life. Some of these wasps perform a great service by killing large numbers of plant-feeding insects and nuisance flies.
Left on their own, wasps are not a problem. They become a problem when they sting, or threaten to sting humans. Luckily there are steps to take to reduce the potential for interactions with these potential pests. UC ANR’s Yellowjackets and other social wasps publication can help.
Topics include:
- Identification and life cycle
- Injury or damage
- Management

Recently our office has received many calls about bee swarms. These calls are typical at this time of year. Each swarm can contain 5,000 to 20,000 bees.
Understandably bee swarms can cause uneasiness to residents unfamiliar with honey bees. While the swarms might seem frightening, the common honey bee is extremely docile. Unless they feel threatened they are unlikely to react defensively.
Swarming bees are in search of a new home. Honey bees prefer dark cavities with an easily defendable entrance at least 9 feet from the ground. Hollowed out trees are ideal sites, but other favored sites include: inside walls of houses, in or around chimneys, in outbuildings, fences, shrubs, water meters, utility boxes, barbecue grills, or under decks.

The Natural Resource Conservation Service (NRCS) works extensively with the nation’s farmers and ranchers to protect soil, water, air, plant, and animal resources while meeting production goals.
Working with agricultural producers allows NRCS to promote conservation practices approximately 1.4 billion acres of the privately held land in the United States. About 92 million acres of land in our country is tended by home gardeners. In an effort to promote conservation on these lands, NRCS has partnered with other organizations to produce, Backyard Conservation: Bringing Conservation From the Countryside to Your Backyard.
This full-color and informative online resource highlights 10 conservation activities that can be used in your backyard, shared spaces, and public places too.
Topics include:
- Trees add beauty and so much more.
- Trees, shrubs, and other plants can provide homes and food for wildlife.
- A backyard pond will likely become the focal point for all your backyard conservation.
- Wetlands filter excess nutrients, chemicals, and sediment and provide habitat for a host of interesting creatures.
- Composting turns household wastes into valuable fertilizer.
- Mulching cools, protects, and enriches the soil.
- Apply only those nutrients the plants can use. (See our previous post on soil test kits to help you get accurate test results.)
- Terracing makes flower and vegetable gardening possible on steep slopes.
- Drip irrigation and other water conservation practices can save water and money.
- Early detection and treatment of pests means a healthier growing environment.
