CARBON-DIOXIDE EVOLUTION FROM HIGH-MOISTURE SHELLED CORN TREATED WITHIPRODIONE

Carbon dioxide evolution was used to determine the storage life of 22. 7% moisture shelled corn. Four iprodione fungicide treatments plus an untreated control were tested. The fungicide was tested on corn having three levels of mechanical kernel damage: 7% (hand shelled), 25% (com bine harvested), and 16% (a blend of the other two damage levels). All iprodione treatments significantly increased storage life. Corn sampl es with higher levels of kernel damage took shorter times to reach the 0.5% dry-matter loss (DML) level. For combine-shelled corn, the fungi cide increased storage life 17% at 15 mg/kg of com and 46% at 20 mg/kg of com.
