Description

As drought struck corn fields through much of southeastern Iowa in 2005, producers were reminded that mycotoxin problems, especially aflatoxins, often follow drought stress. Aflatoxins (produced by the fungi Aspergillus flavus and A. parasiticus) are a chronic problem for corn producers in some areas of the U.S., such as the Texas panhandle and much of the southeastern U.S. In Iowa, widespread aflatoxin problems occurred in 1983 and 1988, but since then there has not been a severe year for aflatoxins across the state. However, parts of Iowa have seen unacceptable levels of aflatoxins several times since 1988, including 1991, 1997, and 2005.
