Systemic protection for cereals and canola: the Polish standard

"Cerfun" by Agropak is a trusted systemic fungicide that has become a staple in European agronomy. Designed to tackle the most persistent fungal infections, it relies on Tebuconazole, a potent triazole compound known for its rapid absorption and long-lasting curative effect. For many farmers, this product represents the optimal balance between high efficacy and economic feasibility.

Targeting crop threats

The systemic nature of Cerfun allows it to be absorbed into the plant's tissues, moving through the vascular system to stop the biosynthesis of ergosterol in fungal cells. This prevents the further spread of the pathogen, which is crucial for protecting the yield of winter wheat, spring wheat, winter barley, and winter rapeseed.

The product is specifically engineered to combat:

• All major cereal rusts (stem, yellow, and brown).
• Septoria leaf and glume blotch.
• Net blotch and dark-brown spot in barley.
• Alternaria in rapeseed.

Field performance and application

As an emulsifiable concentrate, Cerfun mixes easily and remains stable in the spray tank, ensuring even coverage across the field. With a recommended application rate of 0.5 to 1.0 liters per hectare, it provides the flexibility required for varying levels of disease pressure. Growers may conduct up to two applications per season, allowing for a precise treatment schedule.

Rated as a Class 4 hazardous substance, it is manageable for professional use, provided that the 30-day pre-harvest interval is strictly followed. This cooling-off period is essential to ensure that the active substance fully metabolizes within the plant, leaving the final harvest clean. Cerfun is a reliable, battle-tested solution for farmers looking for consistent, professional-grade crop protection that stands up to the challenges of modern agriculture.
