Quarantine measures should apply, ban growing potatoes in the field during the five years following the finding of infection of potatoes from that field. The result indicated that the antibodies were sensitive enough to detect Ralstonia solanacearum from ginger, chilli, chromolaena and tomato. Plants are particularly vulnerable between seedling emergence and the bloom stage. It is therefore important to have a classification of strains that is sufficient in information content of epidemiology and control of bacterial wilt. Practice a 5- to 7-year crop rotation and dont plant any plants in the nightshade family in infected areas during that time.
