Organic fungicide label Sonata expanded

In the meeting of the Board for the Authorization of Plant Protection Products and Biocides (Ctgb), the label of the biological product is Sonata extensively in the uncovered cultivation of: chicory, strawberries, currant, grapes, blackberry, raspberry, endive, lamb's lettuce, zucchini, pumpkin(-like), parsley, flower seed, vegetable seed, beets, herbs, fiber crops, oilseeds, legumes, forage crops, quinoa, green manure crops, forage crops and chicory, woad, buckwheat, madder, kite, sorghum, teff and millet.

Sonata is based on the bacterium 'Bacillus pumilis QST 2808' and is particularly effective against mildew. Sonata is used preventively. If this attack is already present, a curative fungicide must first be applied to lower the pressure, followed by an application with Sonata.

Other operation
The dose range in uncovered crops is about 5 to 10 liters per hectare, depending on the infection pressure and crop development. For grapes, a dosage of 5 liters per hectare applies. In favorable conditions for powdery mildew, repeat the application after 5 to 7 days.

Sonata has a different mode of action than the previously authorized biological fungicide Serenade:

• The amino sugars produced by the Bacillus pumilis (strain QST 2808) from Sonata ensure that the production of cell walls by fungi is inhibited.
• Serenade is based on the bacterial strain 'Bacillus amyloliquefaciens QST 713'. The effect of this product is achieved by active components (lipopeptides) that are formed by this bacterium during the production process. These 'lipopeptides' make small holes in the cell membranes of the fungus through which the cell contents leak out.

Filling through the different mechanisms of action Serenade and Sonata complement each other perfectly in an integrated cultivation system.

Sonata in brief:

• Preventive biological contact fungicide to combat in particular powdery mildew,
• non-systemic,
• Good coverage necessary,
• Always add a wetting agent,
• Exempt from MRL,
• Safe for food and pollinators.
