agricultural weeds

With the globalization of the agri-food industry, we are witnessing a globalization of the invasion of non-native plants, limited only by climate and the type of activities. This book introduces us to a world where harmfulness is a function of activities (crops, pastures, livestock) and exists at varying degrees along a harm-to-benefit continuum.

Nothing is more complex than living things. Nothing is more relative than the harmfulness of a plant. And, in some plants, nothing is more variable than the characteristics of the species. Add to this picture climate change, global trade, and the introduction of new species, and you'll understand why this book is more of a short treatise on weed science than an identification guide. To help the reader learn to see and speak the language of weeds, the author guides them through the evolution and emergence of the major botanical classes and their roots in terminology, draws illuminating comparisons between species, directs attention to critical details—in short, aims to develop good instincts and reflexes for identification. Anyone seeking basic knowledge, whether in their agricultural training or gardening activities, will be delighted by this beautifully illustrated presentation of the plants that live alongside us and sometimes make our lives difficult simply by behaving as they were born to behave...
