Abstract (AB)	Bacterial wilt caused by Pseudomonas solanacearum is the most serious d isease of potato in Mauritius and is a major constraint to production. Race 1, biovar 3 is the only race of the pathogen identified and is present in most cultivated soils of the island. An integrated approach was developed to manage the disease and has proved very successful in reducing wilt. Before release for commercial plantations, varieties are screened to the pathogen in infested soil and by an infectivity titration method. Planting in cool storage of seeds are standard practices used to control the disease. The population of the bacterium in tubers decreases markedly after storage for six months at 2-4°C. Soil solarisation and soil amendments are being investigated as control measures to reduce levels of soilborne inoculum. Diagnosis of the bacterium in seed and soil by immunofluorescence, ELISA, NCM-ELISA, use of selective media and bioassay methods is also being investigated. More advanced techniques using monoclonal antibodies, DNA probes and PCR have also been acquired. Clones adapted to lowland tropical conditions and resistant to bacterial wilt are being developed in a joint Mauritius Sugar Industry Research Institute-International Potato Centre project.
