The fungicide iprodione was applied with two different amounts of water carrier, 3.29 and 5.48 mL/kg wet corn, to study its effect on the allowable storage time (time to lose 0.59% of original dry matter) for shelled corn (Zea mays) at 18 and 22% moisture (wet basis) and 20 degrees C. Allowable storage time was determined by measuring the amount of carbon dioxide produced by corn samples and by using a carbohydrate respiration model to calculate dry matter loss. Performance of the fungicide was slightly better with the smaller amount of water carrier, but the difference in performance for the two levels of water carrier was not significant (p < 0.05). With the smaller amount of water carrier, the fungicide increased the allowable storage time about 45% for 18% moisture corn and about 16% for 22% moisture corn. At the end of the tests, the 22% moisture corn had higher levels of total damaged kernels than did the 18% moisture corn for all fungicide treatments.
