Of all Vietnam’s cassava fields! Lovely coincidence to meet Hung Ngoc Nguyen during a visit to @ACIARAustralia @BiovIntCIAT_eng project. He told Director of Special Projects @creade1 how useful he’s found our research leadership & management masterclass @jononewby @ShaunCoffey

Constant battle but lots of smiles! Protecting cassava yield thru breeding for disease resistance for Vietnamese farmers -wonderful to hear of success from @jononewby @BiovIntCIAT_eng in @ACIARAustralia project with more income for farmers, cassava regions and the whole country!

#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.

Many comments in #farmer socialmedia groups are discussing the ‘low’ #cassava prices this year. A few figures to consider. Short memories? Recency bias? With #disease 🦠 impacting yields many farmers may now feel the pain masked by higher prices for past 2 years.

Happy Birthday 🎈 5 years since constructed, #NAFRI continues to use the @CassDiseaseAsia rapid multiplication tunnels in Laos 🇱🇦. With new resistant clones on their way from @BiovIntCIAT_eng Vietnam 🇻🇳 FutureSeeds is about to enter a new phase.

New public-private #partnerships required to deliver disease-free motherplants & new #resistant varieties to a network of #entrepreneurial farmer stem multipliers to meet this #smallholder demand.

#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.

VSD #cacao and #CWBD could be sibling diseases, first time observing C. theobromae growing from cacao and cassava petioles at the same time, would it be possible to have plasmogamy with each other?#CassDisseaseAsia cooperation @UPLBOfficial @BiovIntCIAT_eng
