Abstract


Alternari solani Sorauer produces harmful disorders in potato cultures. It is a mushroom with high sensitivity against climatic conditions, rainfall regimen, especially. The aim of this study is to emphasize the influence of the climatic factors upon develpment of earlyblight in potato, and also interactions between the evolution of the earlyblight and climatic conditions. The interaction between the climatic factors of importance in the manifestation and management of the earlyblight in potato attack produced by the attack of the Alternaria solani Sorauer mushroom on the potato variety Redsec (depending on the applied treatment), represented mainly by humidity and temperature, expressed as averages throughout the experimental period 2018 -2019, presents a series of particularities, which, however, are also conditioned by the applied phytosanitary treatments.
