The biological fungicide Serenade is a plant protection agent based on the natural bacterium Bacillus amyloliquefaciens (strain QST 713). It effectively combats fungal and bacterial diseases due to lipopeptide compounds that suppress pathogenic microorganisms. The mechanism of action includes antagonistic effects on pathogens, induction of systemic plant resistance, and comprehensive protection against diseases such as moniliosis, gray mold, bacterial burn, and canker. Serenade does not accumulate in plants, ensuring product purity and safety for the end consumer.
The product is applied by foliar spraying and soil treatment, which helps prevent or halt disease development. It is suitable for treating various crops, including apples, apricots, cherries, grapes, peaches, strawberries, tomatoes, cucumbers, as well as hazelnuts, walnuts, and potatoes. The application rate is 6.0–8.0 liters per hectare. Serenade is registered for soil use in Ukraine and can be used in organic farming systems.
The biological fungicide is safe for pollinators, predators, and soil fauna such as earthworms and collembolans. It integrates well into existing plant protection systems and is compatible with many protective agents and microfertilizers, including copper-based products. Due to its unique biological mode of action, Serenade does not induce pathogen resistance, ensuring its effectiveness over prolonged use and supporting sustainable disease control.
