Erisiphe pisi (de Candolle) is the pathogen that causes powdery mildew in peas, one of the most important fungal diseases. The objective of the research was to estimate the level of the powdery mildew attack in the Alvesta and Nicoleta pea genotypes, under the experimental conditions at ARDS Piteşti-Albota, in the period 2023-2024. The effect of azoxystrobin and azoxystrobin + difenoconazole molecules in controlling the pathogen was determined. The frequency (F %), intensity (I %), degree of attack (G.A %) of the disease and effectiveness (E %) of the treatments were calculated. The results showed that the azoxystrobin + difenoconazole variant had the lowest attack degree 1.47%, followed by the azoxystrobin variant with 2.26% in the Alvesta genotype. In the Nicoleta variety, higher values of the degree of attack were recorded compared to the Alvesta variety. The effectiveness had the highest value, of 82.92%, when applying the azoxystrobin + difenoconazole treatment, for the Alvesta genotype.
