Product Information



Corvus® pre-emergence corn herbicide provides consistent, broad-spectrum control of grass and broadleaf weeds for a full season at just 5.6 fl oz/A. Corvus delivers rapid burndown, long-lasting residual and reactivation for dependable weed control in field corn and corn grown for silage.

Key Benefits

  • Consistent Control – Corvus translocates through the roots and shoots of weeds to provide rapid burndown and long-lasting residual control. Corvus delivers uncompromised weed control through canopy closure, whether conditions turn wet or even hot and dry. In fact, just a half-inch of rain reactivates Corvus and boosts its weed-control properties.
  • Two Modes – With its two modes of action, Corvus controls more than 50 weeds, including those that are resistant to glyphosate-, ALS-, PPO- and triazine-based herbicides, such as Palmer amaranth and waterhemp. Corvus also controls tough grasses, such as woolly cupgrass, yellow foxtail and fall panicum.
  • Extremely Low Use Rates – Convenient, low-dose formulation can be applied from pre-plant burndown through V2 corn with applications in ounces vs. pints or quarts per acre required by other herbicides. Its extremely low use rate means growers face less shipping, storage and handling, and fewer jugs.
