The influences of fungitoxicants on growth and aflatoxin production by Aspergillus flavus

The influence of six fungitoxicants on growth and aflatoxin production by Aspergillus flavus was tested in liquid SMKY medium at two concentrations, viz. 0.1 and 0.5%. Thiram completely inhibited the aflatoxin production at 0.5% concentration. Other fungitoxicants showing more than 60% inhibition were bavistin and daconil. Vitavax (0.1%) and agrosan GN (0.1 and 0.5%) stimulated the growth of fungus and aflatoxin elaboration after 7 d of incubation. Dithane M-45 moderately inhibited aflatoxin synthesis. Treatment with fungitoxicants also alters the ratio of B1 and G1.
