Abstract: The article presents the results of the reaction of the treatment with organic fertilizers Aminobest and Ecosist-Arbanassi on the degree of attack of early and late brown rot on the plum variety Stanley. The examinations were performed in the period 2016-2017 in RIMSA, Troyan, a branch of Dryanovo based on a Polish experience. The results show clearly the fungicidal effect of organic fertilizers in early brown rot /Monilinia laxa/. By the control the percentage of affected annual shoots varies between 8.3% and 9.3%, in the other variants this percentage varies between 3.1% and 4.8%. By considering the degree of damage of late brown rot /Monilinia fructigena/, the results are almost identical to those of the early brown rot. The highest rate of damage on the fruits was reported at the control, respectively 8.9% in 2016 and 12.6% in 2017.
