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...


Sanabria, K.Pérez, W.Sánchez, D.Andrade-Piedra, J.L.[Resistance inductors for potato late blight management in Peru]Resistance inductors for potato late blight management in Peru

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...

Late blight, caused by the oomycete Phytophthora infestans, is a threat to potato cropping systems worldwide. In the Ecuadorian Andes, despite a high late blight incidence in foliage, tuber blight is rare. In this work, the hypothesis that Ecuadorian Andean soils are naturally suppressive to P. i...

The major pests and diseases were identified and quantified on thirteen potato landraces and three bred varieties cultivated in Peru. Late blight (Phytophthora infestans) was the primary biotic constraint affecting plants before flowering with an average severity of 24%. No other pathogens caused...
