Serenade ASO SC

Biological pathogen control: how Serenade ASO SC works

The core of this fungicide is a unique strain of Bacillus subtilis (strain QST 713). This is not merely a chemical agent, but a living microorganism that creates a protective barrier on the leaf surface, preventing pathogen colonization. The mechanism of action is based on the synthesis of lipopeptides—surfactins, iturins, and agglutinins—which disrupt the membranes of fungal and bacterial cells even before they penetrate the plant tissue.

Advantages of contact action and zero pre-harvest interval

As a contact fungicide, Serenade ASO SC does not penetrate the plant, which defines its key practical value: the absence of residues in the final product. The ability to harvest 0 days after application makes it an ideal tool for the final stages of the growing season.

• Spectrum of control: Effective against a wide range of diseases: from early blight and late blight on nightshades (tomatoes, cucumbers) to brown rot and scab on stone fruits (peach, apricot, cherry) and pome fruits (apple).
• Integration into programs: The product fits perfectly into anti-resistance strategies because the multi-component action of the bacterium makes it nearly impossible for pathogens to develop resistance.
• Application flexibility: The suspension concentrate provides a stable formulation that is easy to dose and maintains activity in tank mixes. The application rate varies from 2 to 8 L/ha depending on the crop and infection pressure.

Using Serenade ASO SC allows agronomists to effectively control grey mold in vineyards and currants while minimizing the chemical load on the soil and the consumer. Its classification as a low-hazard substance (Class 4) confirms a high safety profile for operators and beneficial insects, which is critical for intensive horticulture.
