The first biological fungicide! Serenade® SC is a naturally occurring product derived from QST 713 strain of Bacillus subtilis. It stimulates cell elongation thereby contributing to faster shoot elongation and fruit retention and enlargement after flowering. Serenade® SC has bactericidal and fungicidal properties. It has a broad-spectrum and multi-site mode of action, which fuels plant health and growth. When applied, QST713 strain of Bacillus subtilis colonizes the root systems and produces plant growth-promoting compounds. This makes nutrients in the soil more available to the plant. Also, by colonizing the root systems, Serenade® SC exhibits direct contact activity against soil pathogens, thus protecting the plant against harmful diseases in the soil. Serenade® SC can be used during mango flower induction and applied as drench application for healthier vegetable seedlings.
