ROUND UP 1 LTR

Mode of Action

Once applied to the leaf uptake occurs within 1-6 hours and glyphosate moves through the phloem both downwards and upwards within 5 days. It tends to accumulate in the growing points, then evens up throughout the plant, leading to a gradual loss of green colour followed by death between one and four weeks later.

Glyphosate works at a single specific site in the Shikimic acid pathway to inhibit the production of the amino-acids phenylalanine, tryptophan and tyrosine. Amino- acids are the building blocks of protein molecules and once the biochemical pathway is blocked the synthesis of proteins is interrupted and the plant effectively starves to death. The process is temperature related and explains why treated plants take some time to die.
