Abstract

The effect of rock salts, NaCI, propionic acid, NCP.75, plant products — asafoetida, turmeric powder and aqueous leaf extracts ofAzadirachta indica, Lawsonia alba, Pongamia glabra andTridax procumbens on seed colonization and aflatoxin production byAspergillus flavus (NRRL-3000) was studied in two Spanish bunch groundnut varieties (J-11 and JL-24). All these treatments inhibited seed colonization and aflatoxin production to varying degrees. Inhibition of seed colonization with chemicals, plant products and aqueous leaf extracts was observed to range between 17 to 96%, 27 to 100%, and 8 to 75% while inhibition of aflatoxin production ranged from 14 to 74%, 42 to 71%, and 6 to 64%, respectively. In general, salts (20g/L), propionic acid (10mL/L), asafoetida (pure Ig/L and impure 20g/L), andAzadirachta indica aqueous leaf extract (20 g/L) are better in preventing aflatoxin contamination in both the groundnut varieties.
