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...
