Cover: These healthy vineyards in Riverside County's Temecula Valley may be threatened by Pierce's disease, which has destroyed at least 500 acres of area grape-vines since 1997. Although the disease first appeared in California in the 1880's, recent introduction of the nonnative glassy-winged sharpshooter allowed it to spread more quickly. Other California crops, such as almonds and alfalfa, may also be at risk. UC scientists are collaborating on dozens of research projects to prevent and cure Pierce's disease...
