Fundamentals of Weed ScienceElsevier, 06.09.2007 - 688 Seiten This book addresses herbicides and their use as an important aspect of modern weed management, and strives to place them in an ecological framework. Many weed scientists believe agriculture is a continuing struggle with weeds - without good weed control, good and profitable agriculture is impossible. Each agricultural discipline sees itself as central to agriculture's success and continued progress, and weed science is no exception. While not denying the importance of weed management to successful agriculture, this book places it in a larger ecological context. The roles of culture, economics, and politics in weed management are also discussed, enabling scientists and students to understand the larger effects on society. NEW TO THIS EDITION:
