Abstract
This chapter reviews weed management — an enormous problem in all agricultural systems — and highlights the danger of relying entirely on crops that are genetically engineered to resist weeds. Weeds compete with crops for nutrients, water, sunlight, and space, and therefore diminish crop yields. Therefore, farmers have a number of different options to manage their weed populations. Many farmers use chemical weed control as the primary option to control weeds; herbicides target plant-specific biochemical processes. However, overreliance on herbicides results in the emergence of herbicide-resistant weeds. The chapter then considers how herbicide-tolerant crops can be obtained by genetic engineering and can further simplify weed management. It also looks at how sustainable weed management systems require the integration of a diversity of weed control tactics.
