conditions typical of an arizona monsoon were mimicked in the field to inoculate cotton plants with aspergillus flavus. spores, mixed with autoclaved local soil, were blown onto cotton plants having bolls at all stages of maturity, using a modified commercial leaf blower. half the plants were sprayed with water following innoculation. after one month, plants were pulled and the position of bolls mapped. all bolls were examined fo bright-green-yellow fluorescence (bgyf) of lint, and ginned seeds from each boll were assayed for aflatoxin. control non-wetted, non-inoculated bolls had no bgyf lint and no aflatoxin-containing seed. in contrast, 15 of the bolls from wetted, inoculated plants exhibited bgyf; 18 of these bgyf bolls had toxin.
