Abstract

In a field trial at Tifton, groundnuts cv. Starr Spanish, Early Runner and Florigiant were sown to give 2 harvest dates for each cv., and were combine-harvested after 0, 3 and 7 days in windrows. The harvested seeds were placed in boxes (volume 1 ft3) and subjected to (a) no air flow, (b) an air flow of 1 ft3/min, (c) N2 atmosphere, or (d) CO2 atmosphere, for 24, 48 or 72 h. Green or partly dried seed (0 or 3 days of windrow exposure, respectively) subjected to (a) for 24 h showed a high incidence of aflatoxin contamination, which was not reduced by (b). Less aflatoxin developed with (c) and (d), but an offensive odour developed. Starr Spanish produced more aflatoxin than the other 2 cv. Delay in harvesting increased the liability to produce aflatoxin. In a further trial, seed with 10-50% moisture content was wetted and kept in high-humidity chambers for 5 days. Seed with < 30% initial moisture content developed more aflatoxin than that with >30% initial moisture content.-A.C.T.
