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disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated.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 Recent advances in crop protection written by P.Parvatha Reddy and published by Springer Science & Business Media. This book was released on 2012-09-14 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent years, the need to increase food production to meet the demands of rapidly increasing population from a limited land resource necessitated the use of intensive farming systems, with the inputs like narrow genetic base, high dose of fertilizers, pesticides, irrigation, monocropping, etc. which led to the development of diseases and pest. The effect of changing global climate, particularly the sharp increase in CO2 concentration, has increased the susceptibility of plants to pathogens and pests. Because of the chemicalization of agriculture, the age-old eco-friendly pest management practices like sanitation, crop rotation, mixed cropping, adjustment of date of planting, fallowing, summer ploughing, green manuring, composting, etc. are not being practiced, affecting the crops adversely. This has encouraged researchers to look for eco-friendly and novel approaches for pest management. The information on recent advances in crop protection (involving bacteria, fungi, nematodes, insects, mites and weeds) is scattered. The book delves upon the most latest developments in crop protection such as avermectins, bacteriophages, biofumigation, biotechnological approaches; bio-priming of seeds; disguising the leaf surface; use of non-pathogenic strains, plant defense activators, plant growth promoting rhizobacteria, pathogenesis-related proteins, strobilurin fungicides, RNA interference, and variety of mixtures/cultivar mixtures/multilines; soil solarization; biointensive integrated pest management; among several others (fusion protein-based biopesticides, seed mat technology and environmental methods). This book is a ready reference for students, policy-makers, scientists, researchers and extension workers.

Download or read book Introduction to Plant Diseases written by George B. Lucas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year we see a remarkable increase in scientific knowledge. We are learning more each day about the world around us, about the numerous biological organisms of the biosphere, about the physical and chemical processes that shaped and continue to change our planet. The cataloging, retrieval, dissemination, and use of this new information along with the continued development of new computer technology provide some of the most challenging problems in science as we enter the Information Age. With the explosion of knowledge in science, it is especially important that students in introductory courses learn not only the basic material of a subject, but also about the newest developments in that subject. With this goal in mind, we have prepared a second edition of Introduction to Plant Diseases: Identification and Management. We prepared this edition with the same general purpose that we had for the first edition - to provide practical, up-to-date information that helps in the successful management of diseases on food, fiber, and landscape plants for students who do not have a strong background in the biological sciences. We included new information on (1) the precise identification of diseases and the pathogens that cause them, (2) the development of epidemics of plant diseases, (3) the application of biotechnology in plant pathology, (4) the use of alternative methods of crop production and disease management that help protect the environment, and (5) diseases that have become more important since the first edition was published.

Download or read book A Revolution Down on the Farm written by Paul K. Conkin and published by University Press of Kentucky. This book was released on 2008-09-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: At a time when food is becoming increasingly scarce in many parts of the world and food prices are skyrocketing, no industry is more important than agriculture. Humans have been farming for thousands of years, and yet agriculture has undergone more fundamental changes in the past 80 years than in the previous several centuries. In 1900, 30 million American farmers tilled the soil or tended livestock; today there are fewer than 4.5 million farmers who feed a population four times larger than it was at the beginning of the century. Fifty years ago, the planet could not have sustained a population of 6.5 billion; now, commercial and industrial agriculture ensure that millions will not die from starvation. Farmers are able to feed an exponentially growing planet because the greatest industrial revolution in history has occurred in agriculture since 1929, with U.S. farmers leading the way. Productivity on American farms has increased tenfold, even as most small farmers and tenants have been forced to find other work. Today, only 300,000 farms produce approximately ninety percent of the total output, and overproduction, largely subsidized by government programs and policies, has become the hallmark of modern agriculture. A Revolution Down on the Farm: The Transformation of American Agriculture since 1929 charts the profound changes in farming that have occurred during author Paul K. Conkin's lifetime. His personal experiences growing up on a small Tennessee farm complement compelling statistical data as he explores America's vast agricultural transformation and considers its social, political, and economic consequences. He examines the history of American agriculture, showing how New Deal innovations evolved into convoluted commodity programs following World War II. Conkin assesses the skills, new technologies, and government policies that helped transform farming in America and suggests how new legislation might affect farming in decades to come. Although the increased production and mechanization of farming has been an economic success story for Americans, the costs are becoming increasingly apparent. Small farmers are put out of business when they cannot compete with giant, non-diversified corporate farms. Caged chickens and hogs in factory-like facilities or confined dairy cattle require massive amounts of chemicals and hormones ultimately ingested by consumers. Fertilizers, new organic chemicals, manure disposal, and genetically modified seeds have introduced environmental problems that are still being discovered. A Revolution Down on the Farm concludes with an evaluation of farming in the twenty-first century and a distinctive meditation on alternatives to our present large scale, mechanized, subsidized, and fossil fuel and chemically dependent system.
