Have you seen the blaze of super blooms popping up alongside orchards and field crops in our rich agricultural Central Valley? The corridors of poppies, tidy tips, yarrow, baby blue eyes, and redbud planted by farmers, dazzle us with color, but they serve a purpose, too.
The flowers provide nectar and pollen for the pollinators, including honey bees, bumble bees and carpenter bees. Look beyond the buzz, and you'll see other beneficial insects, such as lady beetles (ladybugs) and their larvae devouring aphids, and tiny parasitoid wasps preying on stinkbugs and armyworms. They're (unpaid) pest control agents at work.
Farmers are taking notice. Knowing that most beneficial insects rely on floral...

Bloom where you're planted.
That old adage takes on more meaning when you plant wildflower strips on your farm. Wildflowers add resilience to our farming systems by providing bees with habitat and food - pollen and nectar. And they're not just for honey bees. Many native bees, such as bumble bees and blue orchard bees, are important crop pollinators. Currently about a third of our crops benefit from bee pollination. This includes vegetables, fruit and nuts, as well as crops grown for seed production, including sunflower, melon, and carrot.
Farmers primarily rely on honey bees for crop pollination; generally two colonies per acre are needed. Honey bees are efficient pollinators, but with colony collapse and...

For crying out loud, who doesn't love an onion? Whether you enjoy them in burgers, broths, sandwiches or soups, or deep-fry them as onion rings or serve them with liver, they're to die for and to cry for.
The average American eats 21 pounds of onions per year. Indeed, our appetite for the fresh green as well as yellow, red, and white bulb onions is increasing in the United States, up 70 percent from several decades ago. A valued crop generating $1.2 billion a year, the onion currently ranks No. 2 in the vegetable industry, right behind the potato. Yellow onions account for nearly 90 percent of all onion consumption, followed by red and white varieties.
Onions, cultivated for more than 5,000 years, are one of the most...

On April 30, Barbara Allen-Diaz, vice president of the UC Division of Agriculture and Natural Resources, will wear bees – live honeybees. The event is a fundraiser for undergraduate education, and Allen-Diaz, who has endured bee stings in the past, is willing to take the risk for this important cause. She'll have the help of a noted bee wrangler, UC Davis emeritus professor of entomology Norm Gary. Gary has performed such unlikely stunts as playing the clarinet while covered with honeybees. He will apply a synthetic pheromone to Allen-Diaz's hands to attract the bees,...

Fields with diversified, organic crops get more buzz from wild bees, concludes a synthesis of 39 studies on 23 crops around the world published March 11 in the journal Ecology Letters.
The study found that wild bees were more abundant in diversified farming systems. Unlike large-scale monoculture agriculture, which typically relies upon pesticides and synthetic fertilizers, diversified farming systems promote ecological interactions that lead to sustainable, productive agriculture. Such systems are...
