Unsurpassed grass and broadleaf control for Roundup Ready® crops 


Flexible, Broad-Spectrum Weed Control 

Cornerstone® 5 Plus is a postemergent, nonselective herbicide that is absorbed and translocated throughout annual and perennial grass and broadleaf weeds for "shoots-to-roots" control. Cornerstone® 5 Plus herbicide controls more than 100 annual and perennial weeds and includes a broad spectrum of uses, including over-the-top application to Roundup Ready® alfalfa, canola, corn, cotton, soybeans and sugar beets. 

Adjuvants Enhance Performance 

The use of surfactants and/or other adjuvants with Cornerstone® 5 Plus herbicide is recommended for optimum performance. For the best product performance, use a quality nonionic surfactant such as Class Act® brands or Preference® plus Alliance® adjuvants. Adjuvants that contain ammonium sulfate (AMS) such as Class Act® brands and Alliance® adjuvants are recommended when using hard water or under environmental stress conditions. 

To lock in spray coverage or deposition and lock out drift, include InterLock® or PowerLock® adjuvants.
