The research aimed to test the behavior of the Argessis variety in the organic farming system under the conditions of the Ștefănești Viticultural Center. The study included monitoring the evolution of diseases and pests (Plasmopara viticola, Uncinula necator, Guignardia bidwellii, Eriophyes vitis) during 2024, application of a treatment program adapted to the moment of appearance and intensity of the attacks, as well as evaluating some agrobiological indicators (grapes weight, berry weight, trunk production, sugar content, and must acidity). The results showed that the attacks of mites and downy mildew stopped completely in June after applying treatments with Limocide and Copperfield. In July, black rot settled on the grapes, but was controlled by increasing the dose of Copperfield; the pathogens were no longer present until harvest. Regarding production parameters, the Argessis variety recorded an average grape weight above the values in the specialized literature. The sugar and must acidity levels were within limits close to those reported in the specialized literature. The study demonstrates the efficiency of alternative products to chemical pesticides for ensuring grapevine health and maintaining competitive production parameters.
