Cornerstone® Plus

Flexible, Broad-Spectrum Weed Control 

Cornerstone® herbicides are postemergent, nonselective herbicides that are absorbed and translocated throughout annual and perennial grass and broadleaf weeds for “shoots-to-roots” control. Cornerstone® herbicides control 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® herbicides is recommended for optimum performance. For the best product performance, use a quality nonionic surfactant such as Class Act® brand or Preference® plus Alliance® adjuvants. Adjuvants that contain ammonium sulfate (AMS) such as Class Act® brand 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. 

Application Rate and Recommendations 

Cornerstone® herbicides may be used for non-crop, preplant burndown; preemergent burndown; postemergence on Roundup Ready® herbicide-treated crops; and preharvest or postharvest. To prevent severe injury or plant destruction, avoid Cornerstone® herbicide contact with foliage, green stems and other parts of desirable plants and trees.
