This volume provides principles and practices for ecologically based weed management in a wide range of temperate and tropical farming systems. The authors describe how tillage and cultivation practices, manipulations of soil conditions, competitive cultivars, crop diversification, grazing livestock, arthropod and microbial biocontrol agents, and other factors can be used to reduce weed germination, growth, competitive ability, reproduction, and dispersal. Special attention is given to the evolutionary challenges that weeds pose and the roles that farmers can play in the development of new weed management strategies.

Concerns over environmental and human health impacts of conventional weed management practices, herbicide resistance in weeds, and rising costs of crop production and protection have led agricultural producers and scientists in many countries to seek strategies that take greater advantage of ecological processes and thereby allow a reduction in herbicide use. This book provides principles and practices for ecologically based weed management in a wide range of temperate and tropical farming systems. After examining weed life histories and processes determining the assembly of weed communities, the authors describe how tillage and cultivation practices, manipulations of soil conditions, competitive cultivars, crop diversification, grazing livestock, arthropod and microbial biocontrol agents, and other factors can be used to reduce weed germination, growth, competitive ability, reproduction and dispersal. Special attention is given to the evolutionary challenges that weeds pose and the roles that farmers can play in the development of new weed-management strategies.

This collection features five peer-reviewed reviews on weed management in regenerative agriculture. The first chapter provides an analytical review of the adoption of Conservation Agriculture (CA) in Sub-Saharan Africa by smallholder farmers, focusing on the challenges posed by weed management. The chapter assesses chemical and non-chemical weed control methods and their benefits in CA systems. The second chapter considers the adoption of integrated weed management (IWM) in organic cropping systems, focussing on the key challenges that can arise as a result of this adoption. It also presents examples of successful integration between preventive, cultural and direct tactics in an IWM strategy. The third chapter highlights an increasing need for IWM strategies in the face of herbicide-resistant weeds, soil degradation and environmental contamination by herbicides. The chapter reviews the cultural techniques available to manage weeds in a sustainable manner. The fourth chapter introduces the concept of using crop rotations and cover crops as an effective and sustainable strategy for controlling weeds and looks ahead to future research in this area. The final chapter utilises four detailed case studies from across Europe to illustrate the effectiveness of combined methods to control weeds and preserve/improve farmers’ income.
