VIDEO: When mixing glyphosate, all water is not created equal

Crop Diagnostic School: It doesn't hurt to check your water source if you think your herbicide is underperforming

With the amount of time and expense producers put into spraying glyphosate, they need to know that their efforts will be rewarded with dead weeds as much as possible. But did you know there could be minerals hiding in your water source that can reduce glyphosate’s effectiveness? At the recent Crop Diagnostic School, Allan Dawson spoke with Jeanette Gaultier, weed specialist with Manitoba Agriculture, about how water quality can affect the efficacy of glyphosate and what steps you can take if you have to rely on a hard water source when mixing your herbicides.
