This paper presents the results of testing new remedies for control using fungicides with rapid uptake in plants against the obligate parasitic pathogen Polystigam rubrum that causes red spot on plum leaves. The action of phytosanitary products, Signum, Folpan 80 WDG, Bellis, Amistar, Score EC was investigated in terms of their effectiveness, comparing those with a single active substance and those with two active substances, the results obtained being without obvious differences in terms of their effectiveness, which allows their recommendation in the integrated management of plum protection. Amistar and Bellis fungicides are part of the strobilurin category with systemic and contact action at the same time, being the most recommended in plum protection against the fungus Polystigam rubrum because they have immediate action upon the appearance of the disease and then later during the vegetation period of the trees. Reducing crop losses requires addressing the problem of identifying effective measures for plum protection, which would contribute to reducing the intensity of the development of key diseases and their harmfulness, by applying a minimum number of chemical treatments. The success of combating diseases through chemotherapy requires the correct determination of the timing of treatment applications, the use of highly effective fungicides, as well as the diversification of the range of approved chemical products.
