The purpose of the paper was to monitor the attack of pathogens Polystigma rubrum and Stigmina carpophila and making observations regarding the phytosanitary intervention on their attack on the plum in the research area in 2019. The biological material it was represented of cultivars: Stanley, Anna Spath and Romanian Gras. To the cultivar Romanian Gras it was noted that the attack of the micromicetes has diminished in the treated variants at 6.2% the attack of Polystigma rubrum and 8.2% of the attack of Stigmina carpophila fungus. Highest efficiency value has been registered at Romanian Gras cultivar with E = 69.75% in protection against Polistigma rubrum, and 71,1% against Stigmina carpophila followed by Stanley cultivar with effectivenes around 69% against the attack of micromicetes monitored.
