5. Cassava Mosaic Disease


Cassava Mosaic Disease (CMD) is caused by a group of viruses collectively known as Cassava Mosaic Viruses (CMVs). Sri Lankan Cassava Mosaic Virus (SLCMV) is the most common strain found in Thailand, which spreads through two main vectors; planting infected cuttings and via whitefly (Bemisia tabaci). Presently, the epidemic has shown continuous expansion, affecting a significantly wider area. Recognising the impact of this threat, SWI contributed a part of land to collaborate with research institutions to breed and introduce new cassava strains with resistance and tolerance capabilities against the CMD, whilst offering guidance to farmers within our network for sustainable cultivation practices.
