Zamzows StayPut is a combination spreading/sticking and penetrant agent designed to provide better distribution and adhesion on the leaves of plants with all types of herbicides. Finally, use a trustworthy formulation of glyphosate. We do not recommend it, and here are the reasons why.The easiest way to explain a surfactant is that it makes water wetter. Do you ship out of state? Always add non-ionic surfactant. The vinegar + salt solution will probably burn the weeds down faster than glyphosate, but glyphosate would likely work slightly better over the long term, especially on large weeds. If nothing else is readily available when you're ready to tackle those weeds, add 1 tablespoon of household dish detergent to 1 gallon of herbicide. Glyphosate is a popular herbicide used to kill certain plants and grasses, manage how plants grow, get crops ready for harvest, and ripen fruit.
