PRIDE 105 OD

Active substance:

mesotrione, 75 g/l + nicosulfuron, 30 g/l

Formulation:

oil dispersion

Packing:

1 L, 5 L, 10 L, 20 L

Mode of action:

Nicosulfuron – absorbed by the leaves and stalks of weeds, inhibits cell division by blocking the enzyme ALS (acetolactate synthetase), which is involved in the synthesis of basic amino acids. Weeds quickly stop growing and competing with the crop, take a reddish shade after a week and gradually die completely (after about three weeks).
Mesotrione inhibits the enzyme HPPD (pi-hydroxyphenyl-pyruvate dehydrogenase), which is involved in the conversion of tyrosic acid to plastoquinones.
The last are an important elements in the synthesis of carotenoids. These compounds, expand the absorption spectrum of chlorophyll to infrared, thus mesotrione is an inhibitor of photosynthesis. Weeds quickly stop photosynthesis, lose their green color and die. Mesotrione also has a prolonged soil effect. (It is capable of controlling the emergence of several subsequent waves of annual dicotyled weeds in the soil).
