The West Coast Rodent Academy (WCRA) is a three-day intensive educational workshop hosted by University of California Cooperative Extension in association with the Pest Control Operators of California, Target Specialty Products and Univar. The event was recently held at the University of California's Agricultural and Natural Resources South Coast Research and Extension Center (SCREC) in Irvine, CA.
Managing rodents in urban environments can often be very challenging. The WCRA was created...
/span>Domestic pigs are a familiar farm animal, but have you heard about wild pigs? These animals are destructive pests with voracious appetites and eat a wide variety of plants and animals. It's estimated wild pigs cause $1.5 billion in economic damage to agriculture and the environment in California every year!
Where Did They Come From?
Domestic pigs were released in California in 1769 to be raised for consumption. Some of these pigs were not recaptured and became feral. In the 1920's, Russian wild boars were brought to California for sport hunting. Since both types of pigs belong to the same species, they interbred. Their descendants are called wild pigs.
Why are They a Problem?
Male wild pigs can weigh...
/h2>/h2>Winter slows down many garden pest problems, but it's also a key time for gardeners to take actions to prevent certain pest problems that occur in the spring. One of the most important of these preventive practices is application of dormant treatments for peach leaf curl.
Caused by the fungus Taphrina deformans, peach leaf curl is a very serious disease, which affects only peach and nectarine trees. Its most distinctive symptom is distortion, thickening, and reddening of foliage as trees leaf out in the spring. Damaged leaves often die and fall off trees but will be replaced with new, usually healthy leaves once the weather turns dry and warmer. A leaf curl infection that continues untreated over several years will...

A new plant pathogen in the genus Phytophthora (pronounced Fie-TOF-ther-uh) has recently been found in several California native plant nurseries and habitat restoration sites. The pathogen, Phytophthora tentaculata, poses a risk of disease in wildlands, gardens and landscapes that use susceptible California native and non-native plants. Once introduced in these areas, the pathogen can generate disease for years to come, potentially causing lasting environmental and economic...

Now is the time to prepare your garden and landscape for winter. The simple tasks recommended below will help prevent perennial weeds, insect pests, and certain disease pathogens so these problems don't get established and become difficult later.
Weeds
- Manage weeds using nonchemical methods such as cultivation, handweeding, or mowing.
- Prevent weeds using competitive plants, mulches, and hand removal.
- Herbicides (weed killers) are rarely needed in established landscape plantings when nonchemical controls are used regularly.
