Alterno

Synergy against hidden threats: why Alterno works more effectively

In the segment of fungicides for rapeseed and peas, the battle for harvest often depends on the product’s ability not just to cleanse the field, but to provide long-term physiological protection. Alterno by BASF S.A. stands out among specialized agents due to its combination of pyraclostrobin and metconazole. This solution, belonging to the "strobilurin + triazole" class, hits pathogens on several fronts simultaneously.

Combatting key pathogens

The product demonstrates high efficacy against a wide range of diseases: from Alternaria and Phoma to the dangerous Sclerotinia, anthracnose, and Phomopsis. The systemic action of metconazole ensures rapid penetration into plant tissues, suppressing the mycelium from within, while the contact component of the strobilurins creates a reliable shield on the leaf surface. This is particularly critical when working with peas, where Ascochyta blight can destroy a significant portion of pods before maturity.

Advantages and application features

• Comprehensive control: mitigates the risks of resistance development by combining two different modes of action.
• Flexibility in consumption rates: a range from 0.5 to 1.0 l/ha allows for adapting the protection strategy to the current phytosanitary situation in the field.
• Biological effect: pyraclostrobin not only fights fungi but also activates photosynthetic processes, helping the plant better withstand stress factors such as drought or temperature fluctuations.

Who is this fungicide for?

Alterno is an optimal choice for farmers focused on intensive production. It is indispensable when mixed infections are observed in rapeseed or pea fields. Adhering to the protocol (no more than 2 treatments per season) and considering the hazard class 2 rating, the product delivers stable results even under high infection pressure. This is a solution for those seeking a balance between treatment costs and the quality of commercial grain, eliminating the risk of massive crop infestation by Sclerotinia or Phomopsis during critical growth phases.
