A highly toxigenic fumonisin producing strain of Fusarium moniliforme (FM3 S.29) was isoiated from maize grains. Among organic acids supplemented to the medium for multiplication of the pathogen, benzoic acid was found to be the most potent inhibitor of fumonisin elaboration followed by propionic acid and sorbic acid. At 0.1 % concentration, benzoic acid and propionic acid checked the fumonisin B1 formation upto 91.66% and 90.00% respectively. Further at 0.2% concentration both benzoic and propionic acid completely checked the FB1 production. However FB2 production was totally inhibited at the lowest concentration (0.1 %) of benzoic acid and propionic acid. Sorbic acid had the least inhibitory response towards fumonisin production. In the case of food preservatives, sodium benzoate was proved to be most effective inhibitor of fumonisin production. At 0.2% concentration sodium benzoate checked FB1 production by 95% and at 0.3% concentration, complete inhibition of FB1 production was recorded. In the case of potassium metabisulphite and sodium metabisulphite, the complete inhibition of FB1 production was found at 0.4% concentration. Further FB2 production was completely checked at 0.1 % concentration of sodium benzoate, 0.2% concentration of potassium metabisulphite, 0.3% concentration of sodium metabisulphite, respectively.
