Photo 1. Early infection of a corm by mitimiti nematode, Hirschmanniella. At this stage, decay is mostly in the outer parts of the corm.
Photo 2. Late symptoms of mitimiti; infection by the nematode, and secondary rot-causing organisms, has caused complete decay of the corm.
Photo 4. Stunted taro growing on the atoll of Ontong Java, Solomon Islands. Taro was a major crop in the atoll before the introduction of Hirschmanniella.
