Citrus canker and huanglongbing (HLB, or citrus greening) are two serious diseases that affect crops around the world, but have not yet infected California groves. This publication tells how to help keep the diseases out of California, and how to recognize them if or when they do arrive.

This book, written by a team of experts on the Asian citrus psyllid, gathers together everything currently known about the biology and ecology of this important pest species, examines the transmission and acquisition processes of the pathogen, and looks at current management practices and their effectiveness. The potential for new, innovative management techniques are also described, along with the economic implications of managing this rapidly establishing disease.
The Genus Citrus presents the enormous amount of new knowledge that has been generated in recent years on nearly all topics related to citrus. Beginning with an overview of the fundamental principles and understanding of citrus biology and behavior, the book provides a comprehensive view from Citrus evolution to current market importance. Reporting on new insights supported by the elucidation of the citrus genome sequence, it presents groundbreaking theories and fills in previous knowledge gaps. Because citrus is among the most difficult plants to improve through traditional breeding, citrus researchers, institutions and industries must quickly learn to adapt to new developments, knowledge and technologies to address the biological constraints of a unique fruit-tree such as citrus. Despite the challenges of working with citrus, tremendous progress has been made, mostly through advances in molecular biology and genomics. This book is valuable for all those involved with researching and advancing, producing, processing, and delivering citrus products. - Includes the most current research on citrus genomic information - Provides the first detailed description of citrus origin, a new proposal for citrus taxonomy, and a redefinition of the genus Citrus - Details citrus challenges including climate change, global disease impacts, and plant improvement strategies
Citrus production is complex, requiring a delicate balancing act during the growing season and lots of preparation. This new manual covers the many steps in the process in a clear and accessible way. This manual also details the latest horticultural and disease issues affecting citrus production. From deciding scion variety and rootstock, to establishing an orchard, to managing production, to postharvest handling, you'll find it all here in a readable format. Colorful photos and clear diagrams and illustrations guide you through important concepts. Chapters cover: History Botany and Physiology Orchard Establishment Pest and Disease Management Postharvest Handling
Huanglongbing (HLB) or citrus greening, first observed more than a hundred years ago in Asia, is the most serious disease threat to the citrus-growing industry worldwide due to its complexity, destructiveness, and incalcitrance to management. First detected in Florida in 2005, HLB is now widespread in the state and threatens the survival of the Florida citrus industry despite substantial allocation of research funds by Florida citrus growers and federal and state agencies. As the HLB epidemic raged in 2008, Florida citrus growers began allocating funds for HLB research in hopes of finding short-, medium-, and long-term solutions. This effort created the Citrus Research and Development Foundation (CRDF), an organization with oversight responsibility for HLB research and development efforts in Florida. This report provides an independent review of the portfolio of research projects that have been or continue to be supported by the CRDF. It seeks to identify ways to retool HLB researchâ€"which, despite significantly increasing understanding of the factors involved in HLB, has produced no major breakthroughs in controlling the diseaseâ€"and accelerate the development of durable tools and strategies that could help abate the damage caused by HLB and prevent the possible collapse of the Florida citrus industry.
A complete guide to citrus cultivation explains how to grow a variety of citrus trees in all climates in the garden, on the terrace or deck, and on a balcony, with tips on overwintering, container gardening, greenhouses, profiles of a variety of citrus species--including oranges, lemons, limes, and more--and dozens of recipes for popular citrus foods.
Of the global population of more than 7 billion people, some 800 million do not have enough to eat today. By 2050, the population is expected to exceed 9 billion. It has been estimated that some 15% of food production is lost to plant diseases; in developing countries losses may be much higher. Historically, plant diseases have had catastrophic impact on food production. For example: potato blight caused the Irish famine in 1845; brown spot of rice caused the Great Bengal Famine of 1943; southern corn leaf blight caused a devastating epidemic on the US corn crop in 1970. Food security is threatened by an ongoing sequence of plant diseases, some persistent for decades or centuries, others more opportunistic. Wheat blast and banana xanthomonas wilt are two contrasting examples of many that currently threaten food production. Other emerging diseases will follow. The proposed title aims to provide a synthesis of expert knowledge to address this central challenge to food security for the 21st century.

Named a Best Book of the Year by The Washington Post, NPR, Vanity Fair, LA Times, San Francisco Chronicle, Huffington Post, The Atlantic, Refinery 29, Men's Journal, Ploughshares, Lit Hub, Book Riot, Los Angeles Magazine, Powells, BookPage and Kirkus Reviews The much-anticipated first novel from a Story Prize-winning “5 Under 35” fiction writer. In 2012, Claire Vaye Watkins’s story collection, Battleborn, swept nearly every award for short fiction. Now this young writer, widely heralded as a once-in-a-generation talent, returns with a first novel that harnesses the sweeping vision and deep heart that made her debut so arresting to a love story set in a devastatingly imagined near future: Unrelenting drought has transfigured Southern California into a surreal, phantasmagoric landscape. With the Central Valley barren, underground aquifer drained, and Sierra snowpack entirely depleted, most “Mojavs,” prevented by both armed vigilantes and an indifferent bureaucracy from freely crossing borders to lusher regions, have allowed themselves to be evacuated to internment camps. In Los Angeles’ Laurel Canyon, two young Mojavs—Luz, once a poster child for the Bureau of Conservation and its enemies, and Ray, a veteran of the “forever war” turned surfer—squat in a starlet’s abandoned mansion. Holdouts, they subsist on rationed cola and whatever they can loot, scavenge, and improvise. The couple’s fragile love somehow blooms in this arid place, and for the moment, it seems enough. But when they cross paths with a mysterious child, the thirst for a better future begins. They head east, a route strewn with danger: sinkholes and patrolling authorities, bandits and the brutal, omnipresent sun. Ghosting after them are rumors of a visionary dowser—a diviner for water—and his followers, who whispers say have formed a colony at the edge of a mysterious sea of dunes. Immensely moving, profoundly disquieting, and mind-blowingly original, Watkins’s novel explores the myths we believe about others and tell about ourselves, the double-edged power of our most cherished relationships, and the shape of hope in a precarious future that may be our own.
