Weeds are a pervasive and expensive problem in California. They can choke waterways, crowd out native species on rangeland, and rob farmers of crop yields. According to the California Invasive Plant Council, the annual cost of invasive plant work in California is at least $82 million.
The University of California has robust educational resources to help those engaged in the battle, and this summer UC Davis and UC Agriculture and Natural Resources personnel are offering a trio of programs to help in the effort.
Weed Day: July 7, 2016
The 60th annual Weed Day will be held at UC Davis on July 7 from 8 a.m. to 4:30...

Most people deal with ants around their home at some point. Because most ants live outdoors, focus efforts on keeping ants from entering buildings by caulking entryways. Follow good sanitation practices to make your home less attractive to ants. Spraying ants inside the home will not prevent more ants from entering. Use baits to control the ant colony. Pesticide baits work by attracting worker ants who then take the poison back to the nest where the entire.../h3>/h2>

Weeds don't just look unsightly, they are also robbing other plants of water, says a UC Agriculture and Natural Resources (UC ANR) expert in a new water conservation video released today.
Any loss of water is a concern as California's fourth summer of drought comes to a close. Missy Gable, director of the UC Master Gardener Program, suggests removing weeds so they won't compete with ornamental plants or edible vegetables.
If weeds are scattered throughout yard and mixed in with plants, hand-weeding is probably the best eradication method. Cultivation can damage ornamentals with shallow roots, bring weed seeds...

Over the last three millennia, the practice of growing rice has evolved and spread throughout much of the globe. From China, through India, to Greece and parts of the Mediterranean and from Europe to the Americas, rice has demonstrated its versatility in desert regions and wetland deltas alike. Abundant in carbohydrates, it is today one of the world’s most widely eaten foods.
While University of California researchers develop rice varieties more tolerant to the modern challenges of climate change — flooding, heat stress, drought — California rice farmers each year discover more new threats in the form of non-native and herbicide-resistant weeds. So well adapted are these weeds that if left unmanaged, they...

In touring the back roads of California’s great Central Valley during wintertime, you may be surprised to come upon hundreds of sheep grazing alfalfa fields. The sheep are penned in by electric fences and graze the fields to near bare soil. Look closely and you may also see some Great Pyrenees dogs, used to guard the livestock from coyotes and other predators. The dogs blend in well with the sheep and it’s often fun to try to spot them in the mob.
You may wonder about this practice of ‘sheeping off’ or grazing alfalfa fields, as sheep are most associated with rangelands in the coastal foothills or the Sierras. Basque sheepherders have historically managed sheep grazing in the Sierra Nevada mountains,...
