Mechanism of action
Active ingredients of the product have a systemic action, enter the weed plants through leaves, and easily move inside the plant to all growing points. The product interferes with the growth processes of meristem cells. The herbicide action is based on the auxin-type reaction.
Picloram and aminopyralid can be absorbed both by the leaves and roots of plants. Moreover, aminopyralid also has a long-term soil activity.
Protective effect period
Throughout the growing period.
Rate of exposure
Weeds stop competing with the crop in a few hours. First visible signs of exposure (twisting, leaf and stalk deformations) appear in 12 to 18 hours. The leaves of susceptible weeds become chlorotic in 1–3 weeks, then a growing point dies.
