Get a Grip on Crop Protection

Don't let growers cut corners when it comes to their yields. 


Even if commodity prices dip, skimping on crop protection investments isn't the way to go. Now, more than ever, it is crucial to help farmers get the most out of every acre.

Don't risk their crop protection investments to low-quality adjuvants or gamble with micronutrients or PGRs that don't have robust data backing them up.

At WinField United, we conduct extensive testing and research on every product before it goes to market to ensure it will perform in the field. From controlled environments and wind tunnels at the Innovation Center to real-life field conditions at our 90+ Answer Plot® locations, our products are put to the test and only make it to market if they pass with flying colors.

Class Act® NG® Adjuvant
Class Act NG adjuvant has been a leader in AMS-based water conditioners for more than 20 years. It combines AMS with a nonionic surfactant and antifoaming agent in a liquid premix. The nonionic surfactant helps improve the spreading and sticking characteristics of the herbicide to improve plant absorption and metabolism, resulting in faster and more effective weed control. Plus, it’s formulated with CornSorb® technology to help improve herbicide uptake and movement in the plant.
