Available in PDF, EPUB and Kindle. Book excerpt: The Cereal Rusts, Volume II: Diseases, Distribution, Epidemiology, and Control is a compendium of papers that aims to control cereal rusts through principles about the nature of the disease, as well as learned strategies toward its control. These papers deal with the major cereal rust diseases such as wheat and rye stem rust, wheat leaf rust, stripe rust, oat stem rust, barley leaf rust. Control of these types of rust diseases include cultural methods, barberry eradication, crop resistance, fungicides, and ecological controls. One paper notes that cultivars, a plant variety developed through selective breeding, should be used. The key to its development with long-lasting resistance is diversity, namely, genetic diversity in resistance types, and diversity in its strategic development, including a combination of race-specific with non-race specific resistance. For example, Parlevliet has pointed out that in natural ecosystems, race-specific resistance can protect the host plant by rendering the pathogen population less aggressive. One paper also examines the use of chemicals for rust disease control in the United States. This compendium is ideally suited for the cytologists, physiologists, biochemists, geneticists, epidemiologists, taxonomists, and cereal plant pathologists.

Download or read book Breeding Pest Resistant Trees written by H. D. Gerhold and published by Elsevier. This book was released on 2013-09-24 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breeding Pest-Resistant Trees documents the proceedings of a N.A.T.O. and N.S.F. Advanced Study Institute on Genetic Improvement For Disease and Insect Resistance of Forest Trees held in Pennsylvania State University from August 30 to September 11, 1964. This book compiles the study and research of geneticists, pathologists, entomologists, and foresters concerned with the genetic resistance of forest trees to pests and breeding programs for disease- and insect-resistant trees. This compilation is divided into three parts. The first part discusses about the résumés of research related to forest tree pest resistance by geographic regions. Part II focuses on the reports of significant research advances in the basic knowledge of disease and insect resistance of forest trees, while Part III includes the discussion of approaches and methods for genetic improvement in pest resistance of forest trees. The topics covered include the variation and inheritance of pest resistance in forest trees; environmental effects on the host-pest relationship; review of basic knowledge of forest tree pest resistance; selection for pest resistance in wild populations; and testing and evaluating inherent pest resistance. This publication is a good source for students and individuals conducting work on the resistance of forest trees to diseases and pest insects.
