Book Description
The germplasm sources highly resistant to Meloidogyne incognita (Southern root-knot nematode) in Upland cotton (Gossypium hirsutum L) contain the resistance QTLs qMI-C11 and qMi-C14. Previous research documented resistance expressed at two stages of nematode development, and later research documented an epistatic interaction between the two QTLs, both of which suggest the QTLs have different modes of action. Our experiments demonstrated that qMi-C11 reduces the number of galls and egg masses, total egg production, and eggs/egg mass whereas qMi-C14 reduces the number of egg masses, total egg production, and eggs/egg mass without reducing galling. Fusarium oxysporum f. sp. vasinfectum (Fov) interacts with M. incognita resulting in increased Fusarium wilt (FW), therefore, we tested the effect of the nematode resistance QTLs on the severity of FW. A reduction of plant growth and an increase in FW severity was seen on all genotypes regardless of nematode resistance QTLs when coinfected with Fov and M. incognita. FW has been reported more frequently in Georgia in recent years, which suggests that something affecting the disease complex may have changed. In 2015 and 2016, a survey of Georgia cotton fields was conducted. The survey showed that Fov race 1 is still the dominant race, but Fov genotypes not previously reported in Georgia were found. Additionally, many instances of FW in Georgia are due to Fov interacting with Belonolaimus longicaudatus and not M. incognita as previously believed.

Book Description
Cotton production today is not to be undertaken frivolously if one expects to profit by its production. If cotton production is to be sustainable and produced profitably, it is essential to be knowledgeable about the growth and development of the cotton plant and in the adaptation of cultivars to the region as well as the technology available. In addition, those individuals involved in growing cotton should be familiar with the use of management aids to know the most profitable time to irrigate, apply plant growth regulators, herbicides, foliar fertilizers, insecticides, defoliants, etc. The chapters in this book were assembled to provide those dealing with the production of cotton with the basic knowledge of the physiology of the plant required to manage the cotton crop in a profitable manner.

Book Description
Soil Solarization describes the principles and technology of soil solarization and the use of soil solarization for different crops and cropping systems. The book evaluates and interprets the extensive amount of literature available on soil solarization in relation to climatic effects and changes in populations of soil-borne microorganisms and weeds. It also compares the advantages and disadvantages of soil solarization with other methods of soil disinfestation, such as soil steaming and fumigation. Soil Solarization explores the effects of soil solarization, covering such points as biological control, changes in soil chemistry involving mineral elements, as well as other changes, such as soil salinity and soil structure. It is suitable for solarizers, researchers working with soil-borne pathogens and soil microbiology, plant protection experts, and other plant researchers and extension specialists.

Book Description
The Plant Root and the Rhizosphere was a major topical feature of the first International Symposium on Factors Determining the Behavior of Plant Pathogens in Soil held at the University of California, Berkeley in 1963. The symposium was edited by K. F. Baker and W. C. Snyder and published under the title Ecology of Soil-Borne Plant Pathogens. Since that time, several other international efforts, either on the root-soil interface specifically or on topics relating to the root environment, have provided"a wealth of valuable information basic to promoting the culture of healthier, more productive plants. For the writing of this book, inspiration has come, in large part, from 10 years of cooperative rhizosphere research in association with leading scientists participating in a regional effort within the southern United States. We have attempted to bring together in this work the major aspects of rhizosphere research and the principles of rhizosphere ecology for the benefit of developing young scientists and technologists, as well as for the established professional researcher and teacher. A prime objective and hope is that this volume might generate ideas that will bring forth new approaches and methodology leading to further advances in our understanding of rhizosphere interactions and their implications for agriculture. ' Because of the enormous complexity of the chemical, physical, and microbiological environment of roots, the methods used by various workers are rarely standardized, but must be devised or modified for each experiment.

Book Description
The papers contained in this book were presented at a NATO Advanced Research Workshop (ARW) held at Cape Sounion, Athens, Greece, 19-24 May, 1991. The twenty-eight more comprehensive papers represent the key subjects of the ARW covered by invited speakers. The thirty-four short papers pre sented in a research format are contributions of those invited to participate in the ARW. There was a total of 70 participants from 21 countries. The objectives of the ARW were as follows: to review current knowledge of biological control of plant diseases and plant parasitic nematodes, with emphasis on mechanisms at the molecular, cellular, organismal, and ecosystem level; to examine and expand on current concepts and synthesize new concepts; to identify and prioritize limitations in the use of biological control for plant diseases and nematodes and the scientific research needed to overcome these limitations; and to develop strategies for biological control through management of resident agents or introduction of natural or modified agents.

Book Description
Plant diseases play an important role on our daily lives. Most of plant diseases are visible and are caused by biotic and/or abiotic factors. Symptoms are usually the results of a morphological change, alteration or damage to plant tissue and/or cells due to an interference of the plant’s metabolism. All basic structures of vascular plants are subject to attack by pathogens. The failure in accurate disease diagnosis and management may lead to huge losses in plant production and related commodities, which causes nutritional food scarcity. Typically, the appearance of a biotic symptom will indicate the relatively late stage of an infection and/or colonization of a pathogen. Expert detection, accurate diagnosis, and timely management play a significant role in keeping plants free from pathogens. In this book expert scholars share their research knowledge and key literature which are vital toward the diagnosis of plant diseases across the globe, addressing traditional plant pathology techniques, as well as advanced molecular diagnostic approach.
