Preservative effects of iprodione on shelled corn.

Laboratory tests were conducted to determine preservative effects of iprodione on 1 kg maize samples, held at 20 deg C, and 18.0, 22.5, and 23.5% moisture while being aerated at 0.45 m3/min-Mg (0.4 cfm/bu). The time required for the samples to lose 0.5% of original dry matter was used as the criterion of preservative effectiveness. Application of 20 ppm of iprodione extended this time by 21% for 18% moisture maize and by 13% for 22.5% maize. Effectiveness of iprodione increased with application rate up to 100 ppm where storage time was extended about 25%. A higher application rate had little added effect. The 3.29 ml/kg (3 oz/bu) fungicide solution rate is more effective than the 5.48 ml/kg (5 oz/bu) rate. Non-uniform application of iprodione did not decrease preservative effectiveness if the same total quantity of fungicide was applied. Damaged kernel totals after storage tests were higher for 22.5% moisture samples, compared to 13% moisture samples, but were not affected by iprodione treatment
