What was the market situation?
In Israel, mangoes, are cultivated on approximately 2,000 – 2,250 hectares. The scope of the orchards are increasing by 100 – 125 hectares per year. The average yield is 25 – 30 tons per hectare (the world’s highest). Israel’s mango industry is mainly based on the varieties Omer, Tali, Shelly, Maya, Kent, Keitt, and King David.
50 – 60 % of the crop is exported, mainly to the EU. *
During storage, stem-end rot (SER) may develop, which reduces the quality of the fruit and can result in up to 40 % of the fresh produce being lost. Bakker Barendrecht, a fruit and veg distributor and importer of Israeli mangoes, contacted Bayer for assistance in tackling the problem that mangoes coming from Israel were very quickly developing a post-harvest disease both in storage and on the shelf.

What was the solution?
The initial solution was 1 – 2 spray applications of Serenade®
ASO during the flowering period to treat powdery mildew and prevent post-harvest diseases. The final spray application occurred at least a week before harvest. An additional solution is currently under development: spraying Luna®
Tranquility in alternation with Serenade®
ASO at the flowering stage and dipping the fruit in Serenade®
ASO post-harvest, to achieve better shelf life and control both powdery mildew and stem-end rot.
