Maintaining a good phytosanitary level of vegetable crops in greenhouses, it is conditioned by application of a complex of measures and means to prevent and control the attack of the pathogen and the pests present in the crops. The main objective of this experience was the control of the pathogen Sphaerotheca fuliginea on zucchini crops in organic and conventional systems, and a comparison was to be made between the efficacy of applied chemical products and the efficacy of biological products. The chemical products (Topas 100 EC 0.5/ L/ha, Amistar 1 L/ha, Cidely Top 1 L/ha, Dagonis 0.6 L/ha) had an efficacy between 73.44 and 96.33%, and the biological products (Fytosave 2 L/ha, Funres 3 L/ha, Mimoten 3 L/ha, Canelys 3 L/ha) between 20.74 and 56.90% for Diana, Perfect and Eskenderany varieties. In the zucchini crops in greenhouses, the chemical products applied in the conventional system had a much higher efficacy than the biological products.
