Making the Case for Water Conditioners

Sprayer

You might not consider how your water is affecting weed control, but without the right water conditioners, you could be reducing your herbicide’s effectiveness by 10% to 20%.1 That means you won’t be getting the most from the dollars you’ve already spent to combat weeds, and it could mean that you’ll spend more on damage control in the future.

Not all water conditioners perform the same way, so here are some tips to get the most from the products in your tank.

Understand the need

Water conditioners tie up cations including calcium, potassium and magnesium in water so that negatively charged herbicide particles don’t bind to them, which can reduce herbicide effectiveness. Cations in the soil or on a leaf can also bind to herbicide particles, so water conditioners help block those interactions to improve herbicide uptake as well. Based on the herbicide you plan to use, there are different types of water conditioners to consider.

Choose the right product

All water needs conditioning, although the rate of water conditioner you apply will depend on the hardness of your water. Ammonium sulfate (AMS) water conditioners are commonly used with glyphosate and glufosinate applications to improve herbicide performance. One option is Class Act® NG®, which combines AMS with a nonionic surfactant and antifoaming agent in a liquid premix. One benefit of Class Act NG is that the predissolved liquid AMS alleviates sedimentation and nozzle plugging in the sprayer. It’s also formulated with CornSorb® technology to help improve herbicide uptake into the plant.

If you plan to spray dicamba, you’ll need to explore non-AMS-based water conditioners. Due to an increased risk of volatility, AMS water conditioners are not labeled for use with in-season dicamba sprays. But you’ll still need to condition water to optimize glyphosate performance with dicamba applications. Class Act® Ridion® is specifically formulated for use with in-season dicamba and is designed to protect glyphosate and other herbicides antagonized by cations in hard water. Class Act Ridion is a dual-chelation chemistry and contains CornSorb technology, two features that set it apart from other non-AMS water conditioners.

There are a lot of water conditioners on the market, so do your research before you make your decision. You only get one shot to eliminate weeds, and the right water conditioner can make a big difference in how effective your control will be. Work with your local WinField United retailer to find the best products to fit your needs.
