Abstract

Abstract

In 1971 and 1973 field tests were conducted to determine if control of the pink bollworm [Pectinophora gossypiella (Saunders)] at or below 5% infestation would reduce the incidence of bright greenish yellow (BGY) fluorescence of cottonseed (Gossypium hirsutum) that is associated with the fungus Aspergillus flavus and the accumulation of aflatoxins. Control of the pink bollworm by application of insecticides on a 5 or 7-day schedule resulted in a decrease in the BGY fluorescence of cottonseed and in the accumulation of aflatoxins. The reduced pink bollworm infestation did not insure that the present FDA guideline of 20 ppb for aflatoxins in cottonseed would be attained.
