First report of Cacao mild mosaic virus associated with cacao mosaic disease in Indonesia.
During 2021, a survey was conducted in Jember, East Java, and Kulonprogo, Yogyakarta on cacao (Theobroma cacao) plantations owned by local farmers, covering an area of c. 400 hectares. Up to 25% of cacao trees exhibited leaf mosaics thought to be associated with Badnavirus infection. DNA was extracted from affected plants and the causal pathogen was identified as Cacao mild mosaic virus (CaMMV) based on nucleotide sequence analysis. This is thought to be the first report of CaMMV infecting cacao in Indonesia.
