"Weed Science and Weed Management in Rice and Rice-Based Cropping Systems will describe the history, production systems and practices of rice cropping systems in major rice-growing countries, and how the unique production practices affect crop-weed relationships which in turn affect weed management practices. It will also attempt to provide an understanding of the basic weed science principles as they apply to tropical cropping situations to be able to compare how weeds behave under multi-crop tropical systems and mono-crop mechanized temperate cropping systems. The ultimate purpose is to be able to apply these basic principles in order to develop improved, efficient, and economically and environmentally sustainable strategies in managing or controlling weeds. This book will discuss the various management methods: chemical, cultural, mechanical, biological, integrated, focusing on the most recent research, particularly on new herbicide chemistries and modes of action, molecular biology and weed genomics and on evolution of herbicide-resistant weeds. For non-chemical (mechanical) control, it will focus on recent developments on robotics and automated weed control and for biocontrol, on the new bioherbicides derived from plant and microbial toxins being developed in the past 5 years. On the most challenging problem in chemical control nowadays, the evolution of herbicide-resistant weeds, recent researches to elucidate resistance mechanisms and use of weed genomics to understand how weeds adapt and evolve resistance to herbicides and the search for practices that could delay adaptation capabilities are also discussed"--
