Late-season glyphosate application in Roundup Ready soybean can be off label

Making one more glyphosate application in Roundup Ready soybean is tempting when weeds are poking through the soybean canopy. However, it is important to remember that there is a maximum soybean growth stage for which glyphosate can be applied to Roundup Ready (glyphosate-resistant) soybeans.

Weeds not controlled prior to soybean emergence can reduce yield

With the wet conditions keeping many growers out of the field, soybean planting is occurring at a slower pace and once conditions are favorable many growers may opt to plant first and apply a burndown later. However, it is extremely important that weeds that are currently in fields be controlled prior to soybean emergence.

No-till Roundup Ready soybean: What you need to know

While glyphosate continues to provide excellent control of most weeds, timely applications before planting and after soybean emergence are necessary to ensure the best growing conditions for your soybean crop. The following recommendations are based on MSU research funded by the Michigan Soybean Promotion Committee (MSPC).

Improve profits with timely postemergence herbicide applications in soybean

Several studies have shown that delaying postemergence weed control strategies can substantially reduce crop yield. This has become more of a concern with the large number of glyphosate-resistant crop acres that rely on postemergence applications of glyphosate for weed control.

Weeds not controlled prior to soybean emergence can reduce yield

Driving around the state I have noticed several no-till fields that still have carpets of winter annual and some newly emerged early summer annual weeds, like common lambsquarters and giant ragweed. With soybean planting is in full swing, it is extremely important that these weeds be controlled prior to soybean emergence.

Weed control in soybean can benefit from preemergence soil-applied herbicides

The flexibility in application timing that glyphosate offers may make it easier to control larger weeds, however the benefits of early-season weed control to protect crop yield can be lost if applications are not made in a timely manner. Additionally, untimely applications can lead to a reduction in weed control.

Improving weed control in no-till Roundup Ready soybean

No-till soybean production in Michigan relies almost exclusively on glyphosate for preplant and postemergence weed control. While glyphosate continues to provide excellent control of most weeds, timely applications before planting and after soybean emergence are necessary to ensure the best growing conditions for your soybean crop.

Soil-applied residual herbicide benefits in soybeans

The use of postemergence (POST) glyphosate in Roundup Ready soybeans has been the primary weed control program used by many Michigan soybean growers. While this system has seemed to simplify weed management, relying on total postemergence herbicide programs can be difficult to manage if not properly implemented.
