An article in the most recent edition of the journal Weed Science shows that cover crops can play an important role in slowing the development of herbicide resistant weeds.
Researchers conducted field experiments in Pennsylvania to explore how cover cropping tactics influenced the management of horseweed in no-till grain crops. Seven cover-cropping treatments were used over two subsequent growing seasons.
Findings - Comparison - Control - Plots - Crop
There were several significant findings. In comparison to fallow control plots, cover crop treatments reduced horseweed density at the time of a pre-plant, burndown herbicide application by 52% in the first year and 86% in the next. This reduced the herbicide "workload"...
