Endemic and Invasive Pests and Diseases:
How UC and its collaborators detect, contain and manage them
Cover:
Across the United States, endemic and invasive pests are a growing problem that costs billions of dollars each year in direct damage and funding for pest management programs. In California, UC ANR researchers collaborate with state and federal agencies to contain and manage pests such as glassy-winged sharpshooter, European grapevine moth and herbicide-resistant weeds. In this photo, Elizabeth Karn, Ph.D. student (left), and Associate Professor Marie Jasieniuk (right) of UC Davis cross glufosinate-resistant Lolium (ryegrass) plants with glufosinate-susceptible plants to determine whether the resistance trait can be transmitted to offspring. The results of their research will help inform resistance management strategies. Photo by Will Suckow.
Water efficiency:
Recycled water, irrigation technology
Cover:
As California enters the third year of an historic drought, with reservoirs at all-time lows and thousands of acres lying fallow, scientists and policymakers are looking for ways to increase water conservation and efficiency across the state. New UC research demonstrates the possibilities and challenges of irrigating crops with recycled wastewater (pages
59,
68,
75) and employing technology to reduce water use in surface-irrigated fields (
page 82). Shown is Trinitas Cellars, which has irrigated its 12-acre vineyard in Napa County with recycled water for over seven years. The color purple on the irrigation tubing is used universally to signify recycled or reclaimed water.

UCCE Centennial: 100 years of science and service
Cover:
This year marks the 100th anniversary of Cooperative Extension (CE), a national system linking land-grant universities with the communities they serve. In California, UC Cooperative Extension (UCCE) advisors provide practical, research-based solutions for problems from farm yields to community health. This issue includes a history of the federal legislation that created CE and UCCE’s milestones over the last century (page 8), as well as current contributions that highlight its continued relevance (page 17). This then-and-now cover image shows UCCE wheat monitoring in Yolo County in 1930 (top) and grassland fieldwork today at Sierra Foothill Research and Extension Center (bottom).
