The aim of this work was the evaluation of physiological behavior of Aspergillus flavavus affected by the application of sub-lethal doses of microencapsulated 2(3)-tert-butyl-4 hydroxyanisole (BHA). For this , peanut meal extract agar (PMEA) and peanut kernels with modified water activity (aw) (0.96 and 0.99) and a sub-lethal dose (0.6 mM) of an BHA formulation was used. Fungl physiological aspects as growth rate, tme to growt and AFB1 evolution were modified by the formulation, especially on PMEA at both aw. In general, conidial and vesicle size of the mold only were affected by growth substrate, being higher on sterile seed than on PMEA regardless of aw condition . However, positive correlation (p
