#CMD or #CBSD — take your pick,
#Viruses movin’ slick like a backstreet trick.
#Whiteflies spread it like it’s just a quick fix,
And the #farmers lose crops, now they’re stuck in the mix.

#Cassava farmers in Southeast Asia are WTP for clean planting materials & new varieties. Supporting market-based clean #seed approaches is an important component of a regional strategy for tackling the #CMD & #CWBD threatening livelihoods & industry.
