Discolored leaves. Decaying roots. Dead wood. Mother Nature offers a fascinating and colorful backdrop of clues to track microscopic killers. Much like any medical mystery, experts are called in to diagnose or identify a disease from its symptoms and recommend management strategies to prevent further damage or loss of healthy plants.
In the world of crop science mysteries, plant pathology solves the crime. The usual suspects include bacteria, fungi and viruses.
Humans and animals depend on plants for their food supply and ultimately for their survival. When diseases threaten crops, a high-quality, affordable food supply is placed at risk. For growers, plant diseases can reduce crop yields. For consumers, reduced...

You can lead a child to fresh fruits and vegetables, but how do you entice them to eat healthful foods when you aren't watching?
“Simply offering healthy options is not enough to motivate children to make healthy choices,” said Sheri Zidenberg-Cherr, UC Cooperative Extension specialist in the Department of Nutrition at UC Davis.
“Moreover, imposing restrictions rather than providing children with options to make healthy choices can have long-term negative effects,” said Rachel Scherr, assistant project scientist, also in the UC Davis Department of Nutrition.
In 2012, more than one-third of children in the U.S. were overweight or obese,...

People love pizza, so they are sure to enjoy the new garden growing at the UC Desert Research and Extension Center in Holtville. A circle planted with wheat, tomatoes, bell peppers, herbs and spices, the garden looks like and produces the ingredients for pizza.
“Pizza can be a healthy meal, if you build it right,” said Stephanie Collins, outreach assistant at the Desert REC. “We can teach kids to add vegetables and educate them about whole grains and non-fat cheese.”
Collins initially envisioned the pizza garden teaching tool when she joined UC Cooperative Extension four years ago as a nutrition educator. The...

Photos of sumptuous dishes are nearly as numerous as cat photos on social media. To sharpen people's focus on healthful eating, UC Cooperative Extension nutrition experts are using photos of food.
In 2011, the U.S. Department of Agriculture unveiled a new food graphic, MyPlate, to remind consumers to choose healthier foods. Work by Cooperative Extension in California that began years earlier influenced the adoption of MyPlate by USDA. Nutrition educators in California began using a plate graphic with USDA's My Pyramid several years ago in a research project with Expanded Food and Nutrition Education Program (EFNEP) and UC CalFresh Nutrition Education Program participants. While evaluating the use of their graphic, which was very...

The San Joaquin Valley is the heart of California agriculture, but hasn't been a hospitable home for commercial avocado production. UC Cooperative Extension specialist Mary Lu Arpaia is conducting research to change that.
Avocados are native of semi subtropical high elevation rainforests in Mexico and Central America. A delicious and highly nutritious fruit, the cultivation of avocado has spread around the world. In California, growers are having commercial success in areas with year-round mild climates, such as San Diego and Ventura counties.
Though avocados are frost sensitive to be sure, it is not the cold winter climate that is the greatest impediment to avocado production...
