Woolly cupgrass is a difficult weed for farmers to manage. Different methods of controlling woolly cupgrass are tested for efficiency and sustainability.

Key Question

1) Why is woolly cupgrass so difficult to manage effectively? 2) How can this research help a farmer manage woolly cupgrass? 3) How does a grower implement this research?


1) Woolly cupgrass has adapted to current production systems and flourishes in current tillage systems, including no-tillage production systems. More importantly, woolly cupgrass has considerably greater tolerance (shown in previous research) to most herbicides or has adapted to current herbicide systems (i.e. glyphosate-based programs). 2) The basic principle that was researched was the impact of various production techniques and how they can collectively provide a better opportunity to manage woolly cupgrass. This reflects not only on woolly cupgrass populations that affect crop yield during the current cropping year, but more importantly, how manipulating the system can negatively impact woolly cupgrass seed banks, thus lessening future infestations. 3) The concept demonstrated reinforces a basic premise of pest management
