【 摘 要 】

The forest health and vitality is threatened by lots of biotic and abiotic agressors, and thus results that global forest ecosystems are affected by a range of diverse factors. The research is aimed at the study of the incidence of powdery mildew in an oak nursery from Pădurea Mare, Satu Mare County, and the effect iveness of measures taken in order to fight against the above mentioned disease. Ternary mineral fertilizer NPK, 15:15:15 was used at a dose of 200 kg/ha. Phytosanitary treatments were performed with 5 products of synthesis. Data were processed with program STATISTICA v 8.0. The most effective management solutions for Microsphaera abbreviata L. fungus to produce oysters in oak trees in the Pădurea Mare Nursery consist in administering treatments with Nativo 300 and Allegro products. The strongest correlations are reported between attack degrees of Microsphaera abbreviata L. and the precipitation regime, ranging from R = 0.328, in the case of the Spheres 535 SC and R = 0.242 phytosanitary products, in the absence of phytosanitary treatments.
