This book was released on 2013-06-29 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a great honor and indeed a privilege for me to write the Foreword to this book, the first of its kind from the Forest Products Research Institute The study of forest insects is now becoming a matter of great concern to many people all over the world because insects damage the already depleted forests and forest resources. In Ghana very little interest was shown in the insects of forest trees and products. But as forest practices have become more intensive so also have the pests on the crops increased and the damage caused increased to alarming proportions. Foresters are now becoming in creasingly aware of the immense havoc that some of these insects can cause. To aid the fight against the pests they have to be fully identified and studied so that effective control measures can be implemented. It is in an effort to bridge this gap in our knowledge that one welcomes this book by Professor Michael R. Wagner, Dr. S.K.N. Atuahene and Dr.

Download or read book Westcott s Plant Disease Handbook written by R. K. Horst and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1242 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.

Download or read book Crop Protection in Medieval Agriculture written by Jan C. Zadoks and published by Sidestone Press. This book was released on 2013-10-16 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mediterranean and West European pre-modern agriculture (agriculture before 1600) was by necessity ‘organic agriculture’. Crop protection is part and parcel of this agriculture, with weed control in the forefront. Crop protection is embedded in the medieval agronomy text books but specialised sections do occur. Weeds, insects and diseases are described but identification in modern terms is not easy. The pre-modern ‘Crop Portfolio’ is well filled, certainly in the Mediterranean area. The medieval ‘Pest Portfolio’ differs from the modern one because agriculture then was a Low External Input Agriculture, and because the proportion of cultivated to non-cultivated land was drastically lower than today. The pre-modern ‘Control Portfolio’ is surprisingly rich, both in preventive and interventive measures. Prevention was by risk management, intensive tillage, and careful storage. Intervention was mechanical and chemical. Chemical intervention used natural substances such as sulphur, pitch, and ‘botanicals’. Some fifty plant species are mentioned in a crop protection context. Though application methods look rather modern they are typically low-tech. Among them are seed disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated. The reality of pest outbreaks and other damages is explored as to frequency, intensity, and extent. Information on the practical use of the recommended treatments is scanty. If applied, their effectiveness remains enigmatic. Three medieval agronomists are at the heart of this book, but historical developments in crop protection from early Punic, Greek, and Roman authors to the first modern author are outlined. The readership of these writers was the privileged class of landowners but hints pointing to the exchange of ideas between them and the common peasant were found. Consideration is given to the pre-modern reasoning in matters of crop protection. Comparison of pre-modern crop protection and its counterpart in modern organic agriculture is difficult because of drastic changes in the relation between crop areas and non-crop areas, and because of the great difference in yield levels then and now, with several associated differences.

Download or read book Archaeology Anthropology and Interstellar Communication written by National Aeronautics Administration and published by CreateSpace. This book was released on 2014-09-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.

This book was released on 2014-02-23 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its creation in 1963, United States Southern Command has been led by 30 senior officers representing all four of the armed forces. None has undertaken his leadership responsibilities with the cultural sensitivity and creativity demonstrated by Admiral Jim Stavridis during his tenure in command. Breaking with tradition, Admiral Stavridis discarded the customary military model as he organized the Southern Command Headquarters. In its place he created an organization designed not to subdue adversaries, but instead to build durable and enduring partnerships with friends. His observation that it is the business of Southern Command to launch "ideas not missiles" into the command's area of responsibility gained strategic resonance throughout the Caribbean and Central and South America, and at the highest levels in Washington, DC.
