Aflatoxin in Arizona cottonseed: lack of toxin formation following Aspergillus flavus inoculation at sutures


, : Aflatoxin in Arizona cottonseed: lack of toxin formation following Aspergillus flavus inoculation at sutures. Journal of the American Oil Chemists' Society 65(1): 127-128

Aflatoxin assays were conducted on seeds from cotton bolls inoculated with A. flavus in commercial fields in Arizona. Inoculations were at sutures at the initiation of boll opening either in the morning or evening in August over a 3-yr period.
