The effect of three fungicides (Vitavax-Captan, Rizolex-T and Sumisclex) and one insecticide (Actellic), when incorporated into liquid medium or applied to corn grains and sunflower seeds, on the production of aflatoxin by A. flavus IMI 89717 was tested. In liquid medium, aflatoxin production was inhibited by 27%, 82%, 100% and 100% when Vitavax-Captan was added at 10, 25, 50 and 100 ppm, respectively. Sumisclex reduced to some extent the production of total aflatoxin, while Rizolex-T and Actellic did not affect quantitatively the mycotoxin production. Rizolex-T proved to be the most effective pesticides tested on aflatoxin production on both corn-grains and sunflower seeds, while Vitavax-Captan was the second most effective pesticide. Both Sumisclex and Actellic did not inhibit aflatoxin production on either corn grains or sunflower seeds at the levels tested.
