Weed Seed Movement via Combines

Crop harvest is here and that means it’s time to be thinking about weed seedbank management. Over the last few weeks we have observed fields throughout Wisconsin with a fair amount of weed escapes. The most troublesome weeds in Wisconsin, waterhemp and giant ragweed, will retain their seeds well into October in the Upper Midwest.

If you are unable to remove weeds that have gone to seed, it is important to develop a sound harvest strategy to minimize the spread of weeds from field to field. This would include cleaning combines between fields and harvesting fields with severe weed infestations last.
