Mechanism of action
Fortissimo, OD is a systemic herbicide. Effective against a wide range of dicotyledonous weeds because of mutually reinforcing effects of three active ingredients.
2,4-D acid acts as an auxin-like growth inhibitor. The herbicide in the form of a compound ether has an increased activity. It penetrates and spreads through all parts of weeds, including roots, easily and rapidly, within 1 hour. It causes deformation of leaves, damage to reproductive organs, and apical necrosis of plants.
The effect of aminopyralid is also based on an auxin-type reaction, disrupting growth of meristematic cells. It is absorbed by weeds both through leaves and roots, and is easily transported to all growth points. Aminopyralid has long-lasting activity in soil, preventing new weed waves.
Florasulam inhibits acetolactate synthase (ALS inhibitors), an enzyme involved in the biosynthesis of essential amino acids in meristematic tissues of weeds. They are mainly absorbed by the leaves of weeds and quickly move to the root system and stems, where they accumulate in growth points and exert a herbicidal effect.
Fortissimo, OD herbicide has an innovative oil formulation: oil dispersion, that provides maximum effect of active ingredients regardless of weather conditions.
