Soft cover. Zustand: New. Ever since its development as a separate subject during the last over six decades or so, weed science is perhaps one agricultural science that is making advances by leaps and bounds, worldwide. Thousands of research papers are published every year, both in the identification of the new weed problems and… finding their feasible solutions. There are several good books on weed management available but what sets this book apart is that it focuses at equipping the students of the first course in weed science, with fundamentals behind each aspect of weeds and weed management in an easy to grasp, text book manner, without missing any quarter of the host of recent developments. This is the key strength of the book. An important feature of advances in weed science is that while, by and large, the older findings remain valid, the new ones act as complements, and not as substitutes to these. Therefore, in this new title of weed science in your hands, care has been taken to maintain the rationality of the basic information on the subject, while incorporating carefully selected, recent research findings. There are sixteen chapters in the book each of which is backed by a set of relevant practical and some mind searching reference questions. In the initial five chapters there is a marked thrust on bringing home to the students the factors that govern the weed occurrence in different crop situations in terms of weed species as well as weed densities. There is emphasis on the insidious nature of weeds and multifarious damages imposed by them on our agricultural and aesthetic environment, and their persistence in nature against all odds. The Chapters 6 to 9 reveal the various options developed by man to deal with weeds in different ecological situations, like the good crop husbandry practices, the use of herbicides and bio-herbicides, the biological control of weeds, and the employment of genetic engineering, allelochemicals, soil solarization, and the like special activities in weed management. These practices, along with the preventive measures, collectively form the subject matter of integrated weed management (IWM) in the book. The strong and weak points of each element of IWM have been highlighted to give students an insight into the subject. The next set of Chapters 10 to 12 are devoted to fundamental functions of more common herbicides available in India, their behaviour in soils and plants, their possible residues in our environment, and the associated effects resulting in the new weed problems. All herbicides have been identified by their common and chemical names. The last set of Chapters 13 to 16 describe in sufficient details the use of herbicides as complements to the other weed control activities in field and vegetable crops, plantations and grasslands, and in the aquatic environment, besides in the treatment of some specific noxious weeds. There is a Glossary of terms often used in the first course of weed science given at the end of the 16 chapters of the book to provide the students a handy, knowledge testing and revision tool. There are nine Appendices in the book which, hopefully, shall complement the text of different chapters. Of these, the Appendix-1 unveils a bonanza of over 60, finely drawn sketches of common weeds selected from the weed flora reported in literature from different parts of India.

Contents Preface. 1. Aquatic weeds and our concern. 2. The survey of aquatic weed problems. 3. Classification of aquatic weeds. 4. Principles of aquatic weed control. 5. Physical control and utilization f aquatic weeds. 6. Herbicidal control. 7. Biological control. 8. Other methods of control. 9. Weed management in fish ponds an…d duck marshes. 10. Weed control in irrigation drainage and flood control systems. 11. Special aquatic weeds their control. Selected bibliography. Glossary of terms. The first edition of this book published in 1979 under the name aquatic weeds was a good success but during the last eight years several thousands of new references have been added in literature and it definitely required updating. This second edition is based on relevant literature available upto 1985. Almost all aquatic weeds mentioned in the edition have been sketched and modern plant classification has been followed in describing these weeds. The problems created by aquatic weeds in different situations in the country have been illustrated state wise. Besides a general view of global aquatic weed problems has also been included. Principles and methods of aquatic weed control have been dealt with in five different chapters. The modern research techniques and practical application aspects for each method of control including physical chemical biological and design control have been discussed in adequate details. The appendices include a detailed list of source of latest information on aquatic weeds and a comprehensive glossary of terms used in aquatic weed science besides the several ready reckoners. (jacket) 300 pp. 46 figs. (illustrator).
