Invasive insects and diseases are threatening numerous tree species throughout the country. Impacts include tree mortality, destruction of forest and urban habitats, and other significant changes in forest ecosystems due to the decline or elimination of tree species. Many of these pests can be transported in inadequately-processed wood, including firewood and discarded wood debris left behind from tree care operations (Figure 1). Preventing the spread of these pests to new areas is critical for.../span>
When you hear the term “pesticide,” what comes to mind? Do you understand what pesticides are and, more importantly, how to use them correctly?
A pesticide is any material (natural or synthetic) used to control, prevent, kill, suppress, or repel pests. “Pesticide” is a broad term that includes insecticides, herbicides (weed or plant killers), algaecides (algae and moss), fungicides (plant diseases), rodenticides, miticides (mite control), and molluscicides (snails and slugs). Even antimicrobial products (such as bleach and sanitary wipes) that kill bacteria on surfaces and chlorine added to pools are pesticides. If a product has a U.S. Enviromental Protection Agency (EPA) Registration Number on...

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>
