How to order

This third edition, newly revised and expanded, is a comprehensive and practical guide that contains biological, ecological, and management information for more than 120 vertebrate, insect, mite, pathogen, and weed pests occurring in almond orchards in California. More than 30 University of California researchers, Cooperative Extension specialists, farm advisors, and pest control professionals contributed to the content. The book provides an ecological framework for making pest management decisions. It covers the development and growth requirements of the almond tree and general management techniques, including identification, field monitoring, control action guidelines, cultural controls, biological controls, and the use of pesticides in an integrated pest management program. Vertebrate pests include ground squirrels, pocket gophers, mice, rabbits, deer, coyotes, and birds. Among the insect and mite pests are navel orangeworm, peach twig borer, San Jose scale, olive scale, European fruit lecanium, mites, oriental fruit moth, borers, ants, stink bugs and other true bugs, carob moth, leafrollers, and tent caterpillars. Diseases include crown and root rots, trunk and branch cankers, vascular system diseases, branch foliage and/or fruit diseases, bud failure disorders, and environmentally caused diseases.
