INTRODUCTION

Because of the importance of weed in agriculture, plant weeds have been the subject of much research, largely directed towards the discovery of methods for their elimination. Nevertheless, weeds are excellent subject for the study of adaptation and microevolution, for they are abundantly available, usually grow fast, and reproduce quickly and easily. Two overall strategies for management of changes in weed communities are apparent. One is to continue the present essentially responsive approach in which shifts in weed composition and development of herbicide resistance are attacked with newly developed herbicides and complex mixtures of existing materials. This approach guarantees a continuing market for new chemical technologies, but leaves the grower with a generally increasing bill for weed control.
