Serenade Opti is an organically certified (ACO and OMRI) biofungicide for use against fungal diseases in grapevines, strawberries and tropical fruit, and bacterial spot in tomatoes, capsicums and chillies. Serenade Opti generally provides similar disease protection as registered synthetic products when used in a season long spray program. Serenade Opti is not systemic and will not control advanced infections but can provide effective protection of clean flowers and fruit. It has no withholding period and is compatible with many commonly used insecticides and fungicides, providing growers with a high level of flexibility when it comes to managing these diseases. Serenade Opti biofungicide is soft on most beneficial species when used as directed and supports resistance management through delivering an alternate mode of action.
