Interpretive Summary:

Technical Abstract: Information on weed management in conservation crop production systems is needed as adoption of practices such as reduced tillage and cover crops become more widespread. This review summarizes recent research on weed management aspects in these systems. Changes in soil environment and patterns of tillage and planting systems may lead to shifts in weed populations and altered management strategies. Weed patterns and populations are not always consistent and vary with locale, crop, and herbicide use. However, in many long-term conservation management studies, a general increase in perennial weeds and grass species has been observed. The development of low-dose herbicides, selective postemergence herbicides, and transgenic crops has greatly improved the flexibility of producers who use conservation systems were opportunities for tillage are limited. With a higher level of management, producers can successfully implement conservation management practices.
