The August 10 derecho left portions of Iowa with broken, uprooted, and damaged corn across a significant portion of the state. Paired with drought conditions across the state, especially in west central Iowa, growers should be on the lookout for mycotoxin issues in this years’ crop, especially aflatoxins and fumonisins, as discussed in “Drought and Derecho Increase Mycotoxin Risk in 2020 Iowa Corn Crop-Scouting and Monitoring Fields”. For fields that are intended to be harvested, considerations for harvest, mycotoxin testing, and storage are presented below.
