The complete bipartite genome (RNA1 and RNA2) of a new nepovirus infecting potato was obtained using small RNA sequencing and assembly complemented by Sanger sequencing. Each RNA encodes a single polyprotein, flanked by 5’ and 3’ untranslate regions (UTR) and followed by a poly (A) tail. The puta...
Late blight caused by P. infestans is the most devastating disease of potato worldwide. To understand the current P. infestans population structure in the Peruvian Andes, 701 single-lesion samples were collected from cultivated potato in different agroecological zones at 2016-2017. Genetic divers...
The effectiveness and efficiency of commercial resistance inductors (RIs) for LB control in the central highlands of Peru were studied. Susceptible plants of cv. Yungay were sprayed with PKplus®, Manvert Biolet®, Miconic® and Manvert Silikon®, and then they were inoculated with a complex P. infes...
Using a semi-structured questionnaire, 1198 Peruvian farmers were interviewed on their knowledge about late blight (LB) and its current management practices. Farmers overwhelmingly considered LB as the main foliar constraint in both potato growing areas. However, most farmers considered the inter...
Fifty-seven accessions of wild potato species and 352 accessions of potato landraces hold in the International Potato Center (CIP) were tested for resistance to late blight (LB) in a series of greenhouse experiments from May to December 2018, in Lima, Peru. Wide phenotypic variation for resistanc...
