The assays were carried out using the Baladin begonia cultivar. The inhibition of B. cinerea mycelial growth and conidial germination was proportional to increases in the concentration of all the products. The inhibition of conidial germination was directly proportional to the concentrations of B. pumilus QST-2808 and B. subtilis QST-713. Coffee oils were less efficient in inhibiting germination than the other products. The crude and roasted coffee oils, potassium and sodium carbonates and bicarbonates, and B. pumilus and B. subtilis sprayed 24 h before, simultaneously, or 24 h after pathogen inoculation inhibited the colonization of begonia leaf discs by B. cinerea. The positive results for the suppression of B. cinerea by the alternative products tested herein merit scrutiny. There is a pressing need to evaluate these products in the management of gray mold, as the severity of this disease is usually high under favorable conditions in greenhouses. aBacillus subtilis aBiological control aCoffee products aGray mold aPlant fats and oils aPotassium carbonate aSodium bicarbonate aSodium carbonate aBacilo aBegônia aBicarbonato aBicarbonato de Sódio aBotrytis Cinerea aCafé aControle Biológico aMofo Cinzento aÓleo Vegetal1 aFUJINAWA, M.
