Tracking The Spread Of Cassava Mosaic Virus

The Sri Lankan cassava mosaic virus threatens 3.5 million hectares of crops in Southeast Asia, highlighting the need for disease-resistant varieties, say researchers.

An international team of researchers has documented the spread of the Sri Lankan cassava mosaic virus (SLCMV) over a single growing season to inform disease control measures. Their findings are published in PLOS ONE.

In 2015, news that the potentially harvest-devastating Sri Lankan cassava mosaic virus (SLCMV) was spreading in Cambodia raised alarm. Since then, containment measures have not improved due to difficulties in detecting the virus, demonstrating the virus’ potential to become a major threat to the livelihoods of millions of smallholder farming families who grow the cash crop on more than 3.5 million hectares in Southeast Asia, generating over US$4 billion of export revenue.
