Roundup Herbicide
Roundup is a non-selective herbicide used to kill unwanted
grasses and weeds. It is available in professional strength
liquid concentrate and professional dry concentrate
formulations. When Roundup is sprayed on plant foliage, it is absorbed and
then moved — or translocated — throughout the plant’s tissues. Once
inside the plant, Glyphosate (the active ingredient in Roundup) inhibits the
production of an enzyme, called EPSP synthase, which in turn prevents the plant from
manufacturing certain aromatic amino acids essential for plant growth and life.
Glyphosate interrupts the metabolic process in plants, so its effect may not be visible
for about four days in annual plants and up to seven days in perennial plants. After
application, the plant wilts and turns yellow, and then turns brown as the plant tissue
deteriorates. At the same time, Glyphosate decomposes the plant’s underground roots
and rhizomes. Ultimately, the entire plant dies, is incapable of regenerating, and
enriches the soil as it decomposes.
Tests have shown that Roundup, when used according to label directions, has no weed
killing activity once in contact with the soil. Glyphosate will not move in or on
the soil to affect non-target vegetation, and it does not move through the soil to enter
other non-target plants by the root system. Glyphosate is only effective when it comes
into contact with the green, growing parts of plants. Other tests have shown that
Glyphosate binds tightly to most soil particles until it is degraded. This means that the
likelihood of Roundup harming nearby plants is negligible, and there is an extremely low
potential for Glyphosate to move into groundwater.
