Harvest despite Pseudomonas syringae pv. phaseolicola strains

This bacterium is not yet causing alarming damage in Burundi. But its pathogenic variability deserves more attention. Previous research affirmed the presence of race 3 of this strain in Burundi. Currently, there are others including GM 133 and strain B; taken from samples from 3 natural regions (Imbo, Mugamba and Bututsi); the agent may also be present in other parts of the country. It should be noted, however, that an additional study could be undertaken for a complete identification of GM 133 and B strains as they are recognised, during this study, as belonging to races different from the others. In conclusion, we have identified sources of resistance among the tested material. Thus, among the 26 bean varieties screened, we were able to identify sources of resistance to this pathogen. These are : IZ 0201382, RWK-11, IZ 0201299, VEF 286, VEF 222, MORE 92042, VEF 235, VEF 168 and VEF 203. However, as pathogens quickly break down resistance, the search for several varieties resistant to this pathogen should be an ongoing activity.
