Nutrient availability is one of the factors that govern the efficacy of biocontrol. The contribution 14 different vitamins, amino acids and nutritional supplement combinations to suppression of Botrytis cinerea by Bacillus mycoides and Pichia guilermondii, alone or in a mixture, was tested on detached strawberry leaflets. Some of the nutritional supplements reduced B. cinerea development and improved biocontrol efficacy. Addition of nutritional supplements to a mixture of the biocontrol agents further improved control efficacy.
