For glyphosate and paraquat, most cover crops can be planted after application. However, depending on the rate of 2,4-D applied, a waiting period of at least 1-4 weeks is necessary before establishing cover crops.

A recent study by North Dakota State University researchers helps farmers determine strategy for growing winter rye as preceding cover crop for dry bean.

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.

Albert Lea Seed agronomists identify 9 unintended consequences that may arise with cover crops and a list of potential solutions. 

The decision on when to terminate cover crops may affect the overall yield of the upcoming cash crop. Research is showing that a later termination may result in a lower overall yield. However, that doesn’t mean early termination is right for your field.
