Summary:According to the European and Mediterranean Plant Protection Organization (EPPO), phytosanitary risk analysis (PSA) is the process of evaluating biological or other scientific and economic evidence to determine whether a pest should be regulated and the severity of possible phytosanitary measures that should be taken against it. The aim of this study is to emphasize the results of a study concerning the phytosanitary solutions for the control of the main diseases in sugar beet in context of climate changes. A multiple correlation coefficient equal to 0.892 (R 2= 79.60%) was obtained, the analysis of the regression line, Y = 7.228 + 0.298X1 + 0.972X2, demonstrates a greater influence of the rainfall regime on the degree of attack and a much greater influence lower thermal regime, similar to the situation recorded in the experimental year 2020. The highest degree of attack of Cercospora beticola Sacc. (1876) was located at the peak of its manifestation around the value of 42%, under the conditions of a rainfall regime starting from 170 mm and thermal from 200C.
