    About this ebook

    This vintage text contains a detailed treatise on the chemistry of agricultural fungicides and insecticides. The huge financial loss associated with the loss of crop due to insects and fungi has led to the artificial control of the pests with a large number of substances - and it is the purpose of this volume to set out the nature and chemical properties of these substances. Full of practical information suitable for both the student and the agricultural professional, this text makes for a worthy addition to any colelction of farming literature. Many antiquarian books such as becoming increasingly hard to come by and expensive, and it is with this in mind that we are proudly republishing this book now in an affordable modern edition - complete with a new introduction on farming.

      Farming

      Agriculture, also called farming or husbandry, is the cultivation of animals, plants, or fungi for fibre, biofuel, drugs and other products used to sustain and enhance human life. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. It is hence, of extraordinary importance for the development of society, as we know it today. The word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, ‘field’, and cultūra, ‘cultivation’ or ‘growing’. The history of agriculture dates back thousands of years, and its development has been driven and defined by vastly different climates, cultures, and technologies. However all farming generally relies on techniques to expand and maintain the lands that are suitable for raising domesticated species. For plants, this usually requires some form of irrigation, although there are methods of dryland farming. Livestock are raised in a combination of grassland-based and landless systems, in an industry that covers almost one-third of the world's ice- and water-free area.

      Agricultural practices such as irrigation, crop rotation, fertilizers, pesticides and the domestication of livestock were developed long ago, but have made great progress in the past century. The history of agriculture has played a major role in human history, as agricultural progress has been a crucial factor in worldwide socioeconomic change. Division of labour in agricultural societies made (now) commonplace specializations, rarely seen in hunter-gatherer cultures, which allowed the growth of towns and cities, and the complex societies we call civilizations. When farmers became capable of producing food beyond the needs of their own families, others in their society were freed to devote themselves to projects other than food acquisition. Historians and anthropologists have long argued that the development of agriculture made civilization possible.

      In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture, including permaculture and organic agriculture. Until the Industrial Revolution, the vast majority of the human population laboured in agriculture. Pre-industrial agriculture was typically for self-sustenance, in which farmers raised most of their crops for their own consumption, instead of cash crops for trade. A remarkable shift in agricultural practices has occurred over the past two centuries however, in response to new technologies, and the development of world markets. This also has led to technological improvements in agricultural techniques, such as the Haber-Bosch method for synthesizing ammonium nitrate which made the traditional practice of recycling nutrients with crop
