Systemic protection for cereals: the mechanics of tebuconazole

«Kolosal c.e.» is a systemic fungicide formulated with tebuconazole (250 g/l), a potent inhibitor of ergosterol biosynthesis. Unlike contact products, this systemic solution is translocated acropetally through the plant tissues shortly after application. This technical mobility is critical for controlling rust diseases and Septoria, as it allows the active ingredient to reach deep-seated mycelia and protect developing leaves and ears.

Technical specifications and formulation

• Emulsifiable Concentrate (EC): This formulation ensures superior stability in the spray tank and optimal adhesion to plant surfaces, reducing the risk of runoff and nozzle clogging.
• Targeting pathogen physiology: By disrupting C-14 demethylation, the fungicide breaks down the cell walls of fungi, transforming it from a preventative tool into a powerful curative agent.
• Versatility: Engineered for use on winter wheat, winter barley, and winter rape, the product provides a comprehensive barrier against leaf spots (net blotch, brown spot) and Fusarium head blight.

Operational guidelines

To ensure maximum efficacy, the product should be applied in 1-2 passes during the active growth stages of the crop, with dosage rates ranging from 0.5 to 1.0 L/ha depending on disease pressure. Given its systemic nature, «Kolosal c.e.» maintains a sustained protective effect. However, operators must strictly adhere to the 30-40 day pre-harvest interval (PHI) to comply with safety standards for final crop residues.
