Instant Insights: Cultural and physical weed control methods (Burleigh Dodds Science: Instant Insights, 125)

This book features five peer-reviewed reviews on the range of cultural and physical weed control methods. The first chapter summarises the range of cultural techniques used to control weeds in Conservation Agriculture systems. The chapter also discusses the effects of these practices on weed seedbanks, space occupation, competition for resources and weed population density. The second chapter provides an overview of physical weed control (PWC), focussing on its aims, principles and mechanisms of mortality. The chapter also highlights the influence of tool choice on the efficacy and selectivity of PWC practices. The third chapter reviews flame weeding requirements, the mechanism by which it reduces weeds and the potential uses of the technique. The chapter also considers the advantages and disadvantages of flame weeding, including its potential environmental impacts. The fourth chapter explores the variety of thermal weed control techniques, such as hot water/steam treatment and laser technology. The chapter also evaluates their efficacy, energy consumption and impact on soil health and crop safety. The final chapter highlights recent advancements in mechanical weed control technologies, focussing on novel inventions and the development of mechanical devices for full-width cultivation, inter-row cultivation and intra-row cultivation.
