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.
Many weed species commonly found in California can be found on the UC IPM website. The site is designed for easy identification.
The identification process is separated by type of weed – broadleaf, grass, sedge, and aquatic. Each of these sections includes: tutorials, high quality photos at multiple life stages, common and scientific names, and recommend management practices.
Resources for home gardeners and agricultural producers are available.
We also have our own website with all the local weeds that was compiled by Susan Latham, UCCE Master Gardener.
Strawberry production growers face many challenges. One such challenge is strawberry anthracnose, which is caused by Colletotrichum acutatum. This plant pathogen is often undetectable on transplants purchased from nurseries for the planting season, but can become very destructive after transplanted into the field.
UCCE’s Oleg Daugovish and collaborators researched this disease and how to best reduce risk and loss. The researchers studied irrigation systems effects on fruit yields, canopy size, and crown tissue infection to determine best management practices.
Their research has recently been published in the American Society for Horticultural Science Journal. You may view the abstract at this site. The full text may also be viewed by following a link on the abstract page. The full article may also be viewed in the UC Cooperative Extension, Ventura County office.
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.

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.
