| Abstract | ||
| Greenhouse and field studies were conducted in two peanut growing seasons. 2001 and 2002 to determine the effect of micronutrients on the incidence of peanut yellow mold caused by aflatoxiqentc fungi (Aspergillus nevus and A. parasiticus) and aflatoxin content. Iron sulphate. manganese sulphate and zinc sulphate at a . 250 and 500 ppm. combined with or without calcium sulphate (Gypsum at 500 Kg/fed. were selected for this study). Dipping peanut seeds in water solution of previous micronutrients showed significant reductions in the incidence of peanut yellow mold and in the frequency of aflatoxigenic fungi. Also an increase in peanut yield. The occurrence of aflatoxigenic fungi and aflatoxin contaminations on shells and seeds increased in zinc sulphate treatments. The additions of Gypsum alone or in combination with the mlcroeternents perform a reduction in yellow mold frequency. Gypsum make microelements more effective in reducing the aflatoxin content in shells and seeds. | ||
