How does PRIMO® HG work?

Apparent Concussion 540 works by absorbing through the leaves and green stems of the plant. Once absorbed, the glyphosate moves throughout the plant’s system, including down to the roots and growing points. It blocks a key enzyme (EPSP synthase) that the plant needs to make essential proteins for growth.

As a result, the plant stops growing, yellows, and gradually dies, including the root system—ensuring complete control and preventing regrowth. Visible symptoms typically appear within 7–10 days under normal conditions.
