Serenade® Opti

Biofungicide

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.

Grower stories

Picking strawberries during the winter months means disease is always a concern for Ti Strawberries at Bullsbrook in Western Australia, however the arrival of an effective biological fungicide is allowing more flexible management and, importantly, helping to reduce the frequent use of other products.
A strong focus on a regenerative and more holistic farming approach, ultimately to help develop horticultural crops that can sustain themselves, has triggered a swing to biological inputs for the Kuzmicich brothers at Carnarvon in Western Australia.
Losses from botrytis in strawberries can be up to 100% in certain cases. So, total loss is quite possible when the conditions are against you and you don't have adequate protection. See how John Frisina and Fresh Berry Co. use Serenade Opti as a key part of their management program.
It’s been a challenging period of spending extra time and money and trialling new systems over the last three years at the Windance boutique winery near Yallingup in Western Australia, but the family-owned business is on target to gain full organic certification in April and is looking forward to the future.
While warmer grape growing conditions have historically helped to limit botrytis bunch rot in the Jindong/Kaloorup area of Western Australia’s Margaret River wine region, it has repeatedly appeared in southern parts of the area

Serenade® Opti biological fungicide delivers on botrytis disease control for strawberries.

As a specialist in berry fruits, John Frisina is focused on helping Yarra Valley growers become more efficient and productive through better pest, disease and nutrition management.
South Australian grapegrower Brian Nitschinsk knows only too well the damage botrytis can cause in a vineyard. In 2016, he dumped 80-100 tonne of Shiraz grapes on the ground following rejection by wineries.
