Technology detects cocoa virus


Swiss agrifood testing company SwissDeCode, in collaboration with Mars Wrigley, has created an on-site test that is designed to detect Cocoa Swollen Shoot Disease (CSSD) in asymptomatic trees in less than 60 minutes.

For decades, cocoa trees are thought to be infected so the virus has been an acute problem for the cocoa and chocolate industry as it can reduce cocoa yield by up to 70%. Until now, no efficient methods to quickly detect the presence of the virus in field in asymptomatic plants had been found.

An exciting new method, adapted to the needs of the cocoa industry 

Built on SwissDeCode’s DNAFoil proprietary technology, and incorporating underlying research from Mars Wrigley, the new solution is an easy-to-perform testing kit that would enable field personnel to quickly test cocoa trees, using their leaves as samples. The test would enable farmers to detect infected trees, even before they show any symptoms, and to take immediate action to prevent the spread of the virus to healthy trees, thus helping to safeguard their current and future income.

The new rapid test provides an opportunity to benefit not only cocoa farms but also cocoa tree nurseries, as it enables monitoring of tree health on a regular basis, and the release of planting materials only when they are substantially free of the virus. Finally, replanting infected areas and regenerating old farms can be conducted with greater peace of mind, helping farmers increase both yields and income while preventing deforestation.

Collaboration with industry players is key

For the development of the new solution, SwissDeCode has partnered with Mars Wrigley, who, for a long time, has been advancing crop science to improve cocoa production across the globe. This successful collaboration has allowed SwissDeCode to understand the specific issues and requirements of end users, from cocoa farmers to trading organizations. Once field validations have been successfully completed, the kit will be ready for largescale use.

Brij Sahi, CEO & Co-Founder, SwissDeCode:

“Seeing that the result of our work helps to solve an issue that is impacting 14 million families makes us immensely proud. We are also making cocoa farming more sustainable, by preventing large-scale deforestation caused by recurring infections.”

Jean-Philippe Marelli, Senior Director Integrated Pest Management, Mars Wrigley:

“We have been looking for reliable preventive solutions against CSSD since the 1940s, as each year cocoa farms are being increasingly affected by this virus. Joining forces with SwissDeCode, we have finally found a rapid and reliable on-site diagnostic!”
