Abstract
A 3-yr field study was conducted to determine the effect of biological control formulations of nontoxigenic strains of Aspergillusjlavus and A. parasiticus, peanut cultivars, and fungicides on preharvest aflatoxin contamination of peanuts. Formulation treatments consisted of (a) no biocontrol treatment, (b) the fungi cultured on rice via solid-state fermentation, (c) conidia of the fungi coated onto the surface of rice, and (d) conidia coated onto the surface of wheat (year one) or hulled barley (years two and three). Experiments consisted of factorial combinations of the four " formulation treatments, two peanut cultivars (Florunner or Georgia Green), and two fungicide treatments (chlorothalonil or combinations of chlorothalonil and tebuconazole). Florunner and Georgia Green peanuts were each planted in 32 individual plots consisting of six rows 15.2 m in length.
