farm sustainability. Increasing incidence of herbicide resistance in weeds and other
crop production or environmental factors may significantly alter invasive weed
dynamics and crop-weed interactions, and will undoubtedly pose future challenges
to crop producers. These and other challenges can be countered by reduced soil
disturbance and diversified cropping systems that combine synergistic components
such as competitive cultivars, relatively high crop seed rate, and judicious fertilizer
placement in true IPM systems. The common alien weed species that persistently
invade Prairie cropland each year will not be subdued over the long term in the
absence of such systems.
