A severe disease was observed in the potato variety Criolla Colombiana . Main symptomatology consisted of discoloration or yellowing of the whole plant, apical leafroll, dwarfing, axillary buds and thicker internodes. Phytoplasmas related to 16SrV and 16SrXII groups were identified by nested PCR...

Frogskin is the most limiting disease of cassava crops in Colombia, causing losses in production up to 90%. Since this disease was associatated with 16SrIII phytoplasma presence, a study was carried out to isolate this phytoplasma using liquid and solid culture media. Root, petiol, stem, leaf and...

Cassava is a staple food for about 800 million people worldwide. It is produced mainly by smallholder farmers. In July 2013, disease symptoms were observed on the crop, including longitudinal lip-like fissures on roots, and a thick cork-like appearance on root peel. The diseased cassava contained...
