Mode of action
Terbutilazin has a systemic effect. It is absorbed by the roots and leaves of weeds, moves acropetally via the xylem. The substance inhibits electron transport during photosynthesis, which leads to the death of weeds.
2,4-D acid /2-ethylhexyl ether/ as part of the product acts as an auxin-like growth inhibitor. It possesses system activity, easily and quickly, within one hour, penetrates and spreads through all parts of weeds, including roots, and blocks cell growth in young tissues.
Nicosulfuron has a systemic effect, which penetrates mainly through the leaves. It is an inhibitor of the formation of the acetolactate synthase enzyme involved in the synthesis of essential amino acids.
Clopyralid has an auxin type systemic effect. It is absorbed by leaves and roots, easily moves along plants and accumulates in the growing point and roots.
The active ingredients contained on Cornegi Plus, OD, possess different herbicidal activity against dicotyledonous and grass weeds. The pronounced synergism and the additive effect of the herbicide components provide an expanded spectrum of action on the weeds and a longer period of their control in maize.
Period of protective effect
Due to the synergy effect and special formulation, the control of annual and perennial grass and annual dicotyledonous weeds is achieved during the whole vegetative period.
Rate of exposure
Under favorable conditions, the growth of sensitive weeds stops within six hours after spraying. The complete death of weed plants occurs within 7-15 days after treatment.
Action spectrum
Annual and perennial grass weeds, annual dicotyledonous weeds.
