New Mutations for Herbicide Resistance Rarer than Expected, Study Finds

After exposing more than 70 million grain amaranth seeds to a soil-based herbicide, researchers were not able to find a single herbicide-resistant mutant. Though preliminary, the findings suggest that the mutation rate in amaranth is very low, and that low-level herbicide application contributes little — if anything — to the onset of new mutations conferring resistance.

Using AMS to Combat Hard Water Antagonism of Postemergence Herbicides

The weed control efficacy of many weak acid herbicides like glyphosate, 2,4-D, clethodium and glufosinate can be reduced by hard water because the positively-charged hard water cations bind to the negatively-charged herbicide molecules, reducing the herbicide's ability to be absorbed into the plant. Find out how adding AMS to the tank can alleviate this antagonism.
