In this study, host-specific forms of the blast pathogen Magnaporthe oryzae in sub-Saharan Africa (SSA) were characterised from distinct cropping locations using a combination of molecular and biological assays. Finger millet blast populations in East Africa revealed a continuous genetic variatio...

Ten genotypes from the Vidac Negro 95 were found resistant to Xcp strains from Dominical Republic. These were: Dor 623, Ju-93-6, ICTA-JU-95-32, 45, 62, 66, 68, 70, 78 and 83. Two of these lines are resistant to Bean Golden Mosaic in Guatemala. A selected population of P. vulgaris genotype was eva...

Disease progress of angular leaf spot caused by Isariopsis griseola Sacc. was determined in the field on 14 bean cultivars after artificially induced infection. Isolate IG1-77 of the fungus was used to cause the infection, and evaluation was made using the CIAT disease severity scale of 1-5. The ...

The current bacterial wilt infestation level in the potato fields in the Peruvian Andes was investigated by collecting stem samples from wilted plants and detecting Ralstonia solanacearum. In total 39 farmers’ fields located in the central and northern Peru between the altitudes 2111 and 3742 m a...
