While many herbicides have long cropping restrictions because they take a long time to break down, there are several herbicides that have a short half-life. Generally, herbicides like Sharpen (saflufenacil), 2-4D and Roundup products (glyphosate) break down fairly quickly in the soil and cause less problems with herbicide carryover.

Proven benefits of cover crops in a corn/soybean rotation have farmers re-evaluating their weed management programs. One critical risk to evaluate is residual herbicide use and potential carryover given the timing of cover crop seeding.

As use of cover crops have increased in recent years managing weeds through a longer residual herbicide program has become more complicated. Herbicides can be one of many possible reasons for decreased cover crop stands or decreased cover crop production.

The 2020 summer was hotter and drier than normal for most farms, so herbicide carryover will be a major issue for planting cover crops. Herbicides degrade based on soil temperature, rainfall, time of application, organic matter, soil type, soil pH, and sunlight. Read more in this article from Ohio's Country Journal.
