    How hard does the water have to be before it effects Gly? The water at the house is only 2 grains of hardness, would I need to find some AMS? What are the ratios to follow if needed?

    Thanks

    It is not just the water hardness. Dirt dust on the leaves can bind to gly making it ineffective. AMS also lowers the ph of the mix making it easier to penetrate the waxy coating on some plants. AMS contains both Nitrogen and sulfur which also benefit the plot. I normally dissolve 2 cups of granular AMS into a 20 gallons water, then add gly. Depending on the AMS, sometimes I'll dissolve it into a bucket of water first, then filter it into the tank. Published mix is up to 17 lbs of AMS per 100 gallons water.

    Your water pH is the bigger issue. As the higher the pH above 7 the quicker the glyphosate becomes inactivated.

    I just did some reading on this, after an ineffective burn down. Make sure you add the AMS before you add the herbicide!

    Granular AMS can clog your sprayer if you pour it in too fast. Pour it in slowly, and stir with a long broom handle or run the tank agitator while pouring. I usually use 48 oz. per 25 gallons of water.
    Besides AMS you should also use a surfactant like crop oil or "hot mes" to help glyphosate work better, 16 oz. per 25 gallons
