New tool calculates crop rotation costs, benefits for California rice growers

UC researchers studying how practice can help farmers manage drought, pests, other challenges Due to severe water shortages, rice acres planted in California plummeted by 37% from 2021 to 2022, according to numbers released recently by the U.S. Department of Agriculture's National Agricultural Statistics Service. But now, thanks to University of California researchers, growers have a new tool they could potentially use to cope with droughts and other environmental and socioeconomic changes. A crop rotation calculator provides farmers in the Sacramento Valley – where 97% of California rice is grown – with projections on the economic impacts of transitioning their fields from rice into four less water-intensive crops: dry beans, safflower, sunflower or tomato. The tool represents an initial attempt to address the dearth of research on rice crop rotation in California, while giving growers much-needed, science-backed data on whether the practice would make financial...

New online pesticide-use course aims to protect water quality

Do you know that some pesticides used around homes and other structures are toxic to small aquatic organisms living in nearby streams, creeks, rivers and oceans? The UC Statewide Integrated Pest Management Program has launched a new online course on runoff and surface water protection in California. This course is designed for pest management professionals working primarily in structural pest control or landscape maintenance, but residents and property managers may also find the presented information useful. Developed by pest management experts from the California Department of Pesticide Regulation (DPR) and the University of California, this course presents information on the Surface Water Protection Regulations that are found in Title 3 of the California Code of Regulations. These regulations were put into place to prevent pesticide runoff into California waterways and to reduce surface water contamination from pyrethroid insecticide use. In this course, you will learn about the...

Where do fall colors come from?

Did you ever wonder why trees "turn" color in the fall? The short answer: It's primarily a function of long, cool fall nights and short, sunny days. The longer answer? Chlorophyll is responsible for the basic green color of leaves we see in spring and summer and is a necessary component of photosynthesis, which uses sunlight to manufacture sugar (food) that is stored during the dormant period of the year. Carotenoids produce yellow, orange and even brown pigments in crops such as carrots, squash, bananas and many ornamental plants such as daffodils and poppies. Anthocyanins are red and orange in color and are most linked to lavish displays of brilliant fall foliage. They also give rise to coloring of strawberries, plums and cherries. Here's the kicker: While chlorophyll and carotenoids are present in leaf cell chloroplasts throughout the entire growing season, most anthocyanins are only produced in fall due to bright light and excess plant sugars within leaf cells. So, in reality...

Books, videos and songs highlight Native views on ‘thanksgiving’

UC takes some first steps in addressing historical wrongs Thanksgiving can be a time of celebration, gratitude and sharing. It is also often a time when people assist the most vulnerable in our communities, through donations to food banks, volunteer service and similar acts of compassion. But it is also a time of remembrance and mourning in Native American communities.  The narrative that many people have been taught beginning in elementary school about the First Thanksgiving celebration in the United States is based on historically inaccurate myths that fail to acknowledge the devastation wrought by settler colonialism, including genocide, land theft, forced assimilation and cultural appropriation. Many Native people refuse to celebrate Thanksgiving; some engage in a day of mourning, protesting the genocide wrought on their ancestors and ongoing oppression. Native scholar Philip Deloria (Standing Rock Sioux) wrote about some elements of this in his contribution...

New interactive web tools help growers cope with climate change

UCCE, USDA California Climate Hub launch CalAgroClimate decision-support tool Climate and weather variability pose increasing risks to farmers. As world leaders gather in Egypt at COP27 to address the climate crisis, University of California Cooperative Extension and the USDA California Climate Hub are launching new web-based tools to provide farmers with locally relevant and crop-specific information to make production decisions that reduce risk. “Integrating historical weather data and forecast information with meaningful agricultural decision support information holds the potential to reduce a crop's vulnerability to such risks,” said Tapan Pathak, UC Cooperative Extension climate adaptation specialist at UC Merced. “To provide easy access to high-resolution data in the form of agroclimate tools and information, and to enhance agricultural resilience to climate and weather-related risks, we are launching CalAgroClimate,” Pathak said. Pathak is...
