The cultivation of cucumbers in greenhouses occupies an important area in Romania. The main foliar diseases and pests on cucumbers have a negative impact on fruit yield and quality. This experiment aimed to study the efficacy of biological and conventional control of powdery mildew (Sphaerotheca fuliginea) and mites (Tetranychus urticae) on cucumber crops in greenhouse. Conventional fungicides (Topas 500EC 0.5 L ha‑1, Amistar 1 L ha‑1, Cidely Top 1 L ha‑1, Dagonis 0.6 L ha‑1) and biological products (Fytosave 2 L ha‑1, Funres 3 L ha‑1, Mimoten 3 L ha‑1, Canelys 3 L ha‑1) are used for controlling powdery mildew. Biological products for the control of the pathogen Sphaerotheca fuliginea had a much lower efficacy compared to chemical control products used in the conventional system. Between conventional (Nissorun 10 WP 0.08%, Floramite 240 SC 0.04%, Voliam Targo 0.06%, Vertab 0.05%) and biological (Amblyseius andersoni) control of mites there are no significant differences.
