Zidua SC herbicide is a pyroxasulfone-based residual herbicide used in soybean and corn production to provide long-lasting control of key grass and small-seeded broadleaf weeds. It is commonly used as part of layered residual weed management programs to help keep fields clean throughout the growing season.

The active ingredient in Zidua SC herbicide is pyroxasulfone, a Group 15 herbicide that controls susceptible annual grasses and small-seeded broadleaf weeds through residual soil activity.

While generic products may contain the same active ingredient, this doesn’t mean it will deliver the same performance.  Performance is a result of the active ingredient AND the formulation properties.  Without the proper formulation products can fail in terms of consistency of performance, level of performance, mixability, etc.  Additionally, growers often evaluate more than chemistry alone. Zidua SC is backed by BASF field research, technical expertise, weed management resources, retailer support, and a long history of performance in U.S. cropping systems.  

Growers frequently add Zidua SC to a post-emergence application to provide residual control of weeds that have not yet emerged. This helps extend control after the initial PRE herbicide has begun to decline and reduces the likelihood of late-season weed escapes. We call these “The August Uglies”.

Zidua SC is often considered when growers need additional residual control after their pre-emergence herbicide, expect extended weed emergence, or want to build a layered residual program against weeds like waterhemp and Palmer amaranth.

Zidua SC is commonly used to help manage annual grasses and important small-seeded broadleaf weeds, including waterhemp and Palmer amaranth, as part of an integrated weed management program.

Zidua SC is frequently used as a follow-up residual herbicide after a PRE application. Layering residual herbicides helps maintain weed control through extended emergence periods and reduces reliance on post-emergence rescue treatments.

Waterhemp can emerge over an extended period of the growing season. Residual herbicides such as Zidua SC help protect fields from later-emerging weeds and reduce the risk of yield loss and expensive rescue applications.

Yes. By extending residual weed control and helping prevent new weed flushes, Zidua SC is commonly used to reduce the likelihood of costly rescue treatments later in the season.

Some growers prioritize proven performance, confidence, retailer recommendations, technical support, and long-term program reliability when selecting a residual herbicide. These considerations may extend beyond product price alone.
