Class Act® Ridion™

New Dicamba Based Herbicide Technologies

Class Act® Ridion™ adjuvant offers an easy-to-use liquid formulation that combines dual chelation chemistry and WinField United's CornSorb™ technology. Class Act® Ridion™ adjuvant ties up harmful cations without the use of ammonium sulfate (AMS).

For new dicamba based herbicide technologies, AMS is not allowed in the tank because it may increase volatility. But, conditioning the water is still necessary to optimize glyphosate performance in the field. Class Act® Ridion™ adjuvant is specifically designed to protect glyphosate and other herbicides antagonized in hard water by chelating cations. Plus it does not adversely affect volatility of dicamba herbicides. The CornSorb™ technology in Class Act® Ridion™ helps droplets spread out increasing coverage and improving humectancy increase uptake which optimizes control for many herbicides.

2 X 2.5-gallon jugs


Class Act® Ridion™ may be used at a rate of 0.5-2.0% v/v (2 quarts to 2 gallons per 100 gallons of spray solution). Optimum rates are 0.75% v/v (3 quarts per 100 gallons) or greater. These rates meet the water conditioning needs of Cornerstone®, Tomahawk®, and other glyphosate herbicides and many other herbicides that could possibly be tank mixed with new dicamba based herbicides. Use lower rates of Class Act® Ridion™ with low water hardness and when weeds are small and actively growing. Use higher rates when water is harder and weeds are difficult to control.
