California parsley is produced typically in high volumes and with high quality. However in the past few years, growers began to observe unfamiliar disease issues in their parsley fields. Leaf spots, blighted foliage and yellowed plants contributed to loss of quality and reduced yields. Steven Koike and Oleg Daugovish, UC Cooperative Extension advisors in Monterey and Ventura counties respectively, stepped in to investigate the new parsley problems. They collaborated with farmers and pest control advisers to understand the extent of the problems and to obtain samples of the diseased crops.
The UC Cooperative Extension plant pathology diagnostic lab in Salinas was successful in isolating and identifying several pathogens that were responsible for causing the disease symptoms. Working with USDA, they found that three new diseases were present in California parsley crops: bacterial leaf spot, Stemphylium leaf spot, and Apium virus Y disease.
Two of these problems are seedborne, so future management will include the use of pathogen-free seeds. The Apium virus Y pathogen is found in weeds, so growers will need to remove poison hemlock, among others.
Previous to this research, some growers were spraying symptomatic fields because they believed that a disease called late blight was responsible for the disease symptoms. Growers have now ceased making these sprays, eliminating the use of unnecessary chemicals and saving costs.
Breakfast: Drink 4 oz. of 100 percent fruit or vegetable juice. Top cereal or yogurt with 1/2 cup of berries or sliced banana.
Lunch: Try a salad as your main dish with the dressing on the side.
Snacks: Trail mix with dried fruit or a piece of fruit such as an apple or an orange is an energizing snack that can also be satisfying if you have a sweet tooth.
Dinner: Enjoy a side of mixed vegetables or have fruit for dessert. All forms of produce count: dried, fresh, 100% juice, canned, and frozen. Try a variety of fruits and vegetables so you don't get bored!
Here are some tips for you and your family to try new foods:
New foods take time. Offer new foods many times. Children don't always take to new foods right away.
Keep portions small. Let your kids try small portions of new foods that you enjoy. When they develop a taste for many types of foods, it's easier to plan family meals.
Be a good role model. Try new foods yourself and describe its taste, texture, and smell to your family.
Offer only one new food at a time. Serve something that is familiar to your child along with the new food. Offering too many new foods all at once could be overwhelming.

You may be thinking, “My family has eaten food that has been sitting on the table longer than two hours and survived.” Consider yourself lucky.
“We keep learning more about foodborne illness,” says Patti Wooten Swanson, UC Cooperative Extension nutrition advisor in San Diego County. “We probably did get sick, but we thought it was something else, like the 24-hour flu.”
She added that kids, diabetics, pregnant women, older adults and people with weakened immune systems are more susceptible to foodborne illnesses.
For the holidays and all year long, Wooten Swanson offers these food safety tips:
- Thaw turkey or meat in the refrigerator.
- Don't wash raw meat or poultry in the sink before cooking.
- Use a meat thermometer to determine when meat or poultry is done.
- Put leftovers in the refrigerator within two hours.
- On the fourth day, throw leftovers away.
“Bacteria grow very rapidly,” she said. “From 40 degrees to 140 degrees is what we call the danger zone. We encourage you to get food out of that temperature range as soon as possible. Don't let food sit on the table after you finish eating and go to watch TV.”
While you're watching football, she also recommends not leaving food out the length of a game.
“Chips are fine to leave out,” Wooten Swanson said, “But put the salsa and guacamole in small containers, then put out new bowls at halftime. Take away the original containers to wash or discard.You don't want to refill a bowl that has been out for 2 hours.”
“We put an emphasis on hand washing because it can prevent cross-contamination, which helps prevent foodborne illness and can keep us healthy during the flu season,” said Connie Schneider, director of the UC Youth, Families and Communities Statewide Program.
She recommends rubbing your hands together with soap and water for 20 seconds to thoroughly clean them.
The UC Expanded Food and Nutrition Education Program (EFNEP) teaches hand washing as a food safety practice in its nutrition classes for adults and children. After taking the class in San Diego County, 72 percent of the 340 participating adults improved their safe food-handling practices and 55 percent of 1,231 children improved, said Wooten Swanson, who oversees the nutrition and food safety education program.

The 175-acre UC ANR Lindcove Research and Extension Center is situated where the valley and Sierra Nevada foothills meet in eastern Tulare County. Research conducted at the center plays a major role in maintaining California's position at the forefront of high-quality citrus production for markets throughout the United States and the world.
Citrus Industry Day - Dec 12: From 9 a.m. to 12 noon, citrus growers, pest control advisers and other industry professionals are invited to taste citrus fruit at their leisure, discuss new low-seeded mandarin varieties with UC Riverside plant breeder Mikeal Roose, and consult with UC Cooperative Extension advisors Neil O'Connell of Tulare County and Craig Kallsen of Kern County. At 10 a.m., UC Riverside plant pathology specialist Georgio Vidalakis, director of the UC Citrus Clonal Protection Program, will explain the center's role in providing the citrus industry with disease-free citrus propagative material. Immediately following the CCPP presentation, UC Riverside principal museum scientist Tracy Kahn will lead a tour of the Lindcove demonstration orchard and discuss new citrus varieties.
General Public Day – Dec 13: From 9 a.m. to 12 noon, Lindcove is open to the public. In addition to citrus tasting, there will be a special activity for children and the opportunity to consult with UCCE Master Gardeners about backyard citrus horticulture and pest management. The tasting event is free. Visitors wishing to take home samples of Cara Cara, Washington navels, mandarins and assorted fruit, may purchase a tote bag full of fruit for $5. All funds raised by the bag sales will supplement educational activities at the center.
At both events, Mary Lu Arpaia, UC Riverside post harvest specialist and David Obenland, plant physiologist at the USDA-ARS San Joaquin Valley Agriculture Center, will be inviting visitors to participate in a research project that involves taste testing of citrus fruits.
The weekend's events mark the launch of Lindcove's Conference Center Outdoor Enhancement Campaign. Funds will be used to upgrade the conference center parking area, plant demonstration orchards and add an outdoor amphitheater where school children can learn about citrus.
“We want to increase our outreach to the community,” said Beth Grafton-Cardwell, Lindcove director and UC Riverside citrus entomology specialist. “These planned improvements will enhance our ability to accommodate school children, tour groups and community organizations for educational experiences at Lindcove.”
The Lindcove Research and Extension Center is at 22963 Carson Ave., Exeter. The tasting takes place in the conference center building, located at the end of Carson Ave. on the right. For more information about the tasting events, contact Anita Hunt, (559) 592-2408, ext 151, firstname.lastname@example.org.
The University of California Global Food Initiative aims to put the world on a path to sustainably and nutritiously feed itself. By building on existing efforts and creating new collaborations among UC's 10 campuses, affiliated national laboratories and the Division of Agriculture and Natural Resources, the initiative will develop and export solutions for food security, health and sustainability throughout California, the United States and the world.
A diet containing lots of vegetables is lower in calories and higher in fiber and good for our health. Yet, not everyone has easy access to fresh vegetables in the United States.
“Growing vegetables and having a garden is an effective intervention to promote increased vegetable consumption among all Americans,” said Susan Algert, UC Cooperative Extension advisor in Santa Clara County, who conducted the survey. “This is evidence for bringing back popular home gardens or ‘Victory gardens' of the past rather than investing exclusively in SNAP benefits for purchased foods.”
SNAP, the federal Supplemental Nutrition Assistance Program (formerly called food stamps), now allows participants to buy seeds with their benefits, which helps low-income people who want to grow their own veggies, she said.
Vegetable consumption falls well below the U.S. Dietary Guidelines in much of the U.S., particularly among African American, Latino, low educational attainment, and low-income populations.
Algert and fellow UC Cooperative Extension researchers looked at background characteristics, vegetable intake and program benefits of people who cultivated a home garden versus those who participated in a community garden.
“The home gardeners were significantly younger, had lower incomes, were less likely to have completed college and were more ethnically diverse than the community gardeners,” said Algert, who specializes in nutrition. “In other words, the background characteristics of the two groups varied significantly. In spite of these significant demographic differences, both groups increased their vegetable consumption from the garden to the same extent, by about two servings.”
In fact, by supplementing with food from their gardens, both groups met the U.S. Dietary Guidelines for recommended daily servings of vegetables to promote optimal health.
A lack of experience as gardeners didn't affect the results much. Fifty eight percent of the home gardeners reported having less than two years of experience whereas only one-third of community gardeners were novices.
“This study demonstrates that growing fresh vegetables in either a home or community garden setting can contribute significantly to a person's nutritional intake and food security at all income levels by making it a more affordable to maintain a healthful diet,” said Algert. Urban gardeners also experience a number of other benefits including exercise, stress release, and learning about gardening from their peers and mentors.
The study was a partnership with the Parks, Recreation and Neighborhood Services Department of the City of San Jose and La Mesa Verde, a project of Sacred Heart Community Services of San Jose. The UCCE research group worked with the Parks Department to administer a 30 question background survey to 83 community gardeners in four different gardens during April through September 2012. The same survey, slightly modified, was administered to a group of 50 home gardeners participating in Sacred Heart's La Mesa Verde project between September 2013 and April 2014.
