This study was carried out to determine the compatibility of Trichoderma citrinoviride spp. Strain 19 on different kinds of fungicides like: organics, chemicals and biological, are all used to control gray mold in roses. The preliminary selection was conducted to select 32 active ingredients (AI), and were excluded the following AI:ascorbic acid, citric acid, lactic acid, a citrus extract, prochloraz and also the mixtures with ISR’s. Later in compatibility assays were evaluated based on the interaction between the antagonistic fungus vs two doses of each active ingredient. After 15th day of incubation, it was evaluated for conidiative capacity of the antagonistic fungus at the first generation and the germination capacity of those conidia. Finally evaluated the best mixtures aimed to control Botrytis cinerea in vitro. The compatible ingredients to be used in mixtures the antagonistic fungus was: ISR’s made of copper, manganese, zinc, specific organic acids, fosfonates, cupric sulphate, ammonium ions, extracts of Azadirachta indica, and others. The results conclude that all of this mixtureis compatible and once checked the results in the field, is possible to reduce the use of synthetic Agrochemicals, preserve natural predators of diseases and pests, lower the atmospheric pollution and reduce the possibility to cause resistance in the disease/plague.
