Citation: Boydston, R.A. 2005. Weeds. In Integrated Pest Management for Potatoes in the Western United States, 2nd Edition, ed. L. Strand. Western Regional Extension Publication 011. R.A. Boydston, Technical Coordinator for Weeds chapter. Interpretive Summary: Weeds are present in all cropping systems and require management in order to prevent yield loss. This chapter discusses weed management in potato production in the Western U. S. An integrated weed management approach that involves field selection and crop rotation, monitoring and field surveys, sanitation of equipment, and proper integration of cultivation and herbicides is presented. Use of herbicides, managing herbicide resistant weed populations, and avoiding problems of herbicide carryover and how they relate to potato crop management are discussed. Knowledge of weed biology and weed identification are critical components of an integrated weed management program. The biology of common weeds of potatoes grown in the Western U. S. is described complete with color photographs.
Technical Abstract: Weeds reduce potato yield and quality and require management in all cropping systems. Weeds can be best managed using an integrated weed management approach that involves field selection and crop rotation, monitoring and field surveys, sanitation of equipment, and proper integration of cultivation and herbicides. Herbicide carryover, managing herbicide resistant weeds, and soil testing are components of weed management requiring careful attention of crop managers. Common weeds of potato rotations, their biology and identification, and control options are discussed in this chapter intended for potato growers and crop managers.
