Developing an emergency response and long term management strategy for Cassava Mosaic Virus in Cambodia and Vietnam

This SRA will deploy a baseline disease diagnostics survey in Vietnam and Cambodia, to assess the geographical spread, local incidence and severity of SLCMD, a Sri Lankan strain of cassava mosaic disease that threatens the livelihoods of South-East Asian cassava farmers.
It will advise national authorities (PPRI, GDA) and private sector actors how to eradicate and replace planting in affected fields. It will train national partners (e.g., scientists, plant protection officers, development workers) to correctly identify SLCMD symptoms, and apply advanced serological or nucleic acid-based techniques for rapid, sensitive, and high-volume viral diagnostics. It will work with national and international partners (incl. CRC Biosecurity) and ongoing plant health programs, and plan multi-country CMD mitigation initiatives based on the results of the baseline disease diagnostics.
The project will also gather vector samples of B. tabaci whitefly populations and information about stake procurement to elucidate seed flows. This will allow the researchers to predict how humans and insects spread SLCMD.
The project will guide medium and long-term mitigation strategies at a local, national and sub-regional level, depending on the actual distribution and incidence of the disease in Vietnam and Cambodia. Its strategy, using robust-applied diagnostics, large-scale baseline diagnostics, national capacity-building and policy engagement, is anticipated to respond to this new regionally important disease threat.
