A foliar fungicide comparison trial was conducted at the University of Nebraska-Lincoln South Central Agricultural Laboratory near Clay Center, NE. DeKalb corn hybrid DKC 64-83, rating of “good” (6 out of 9) for gray leaf spot (GLS), “very good” (4 out of 9) for common rust (CR), and “good” (5 out of 9) for southern rust (SR), was planted on 26 Apr in 30-in. rows at a target population of 30,600 plants/A. The trial area was disked with corn as the previous year’s crop. Eleven treatments and a non-treated control were replicated six times in a randomized complete block design. . . . There were significant differences between treatments for lodging. 500-count kernel weights ranged from 6.56 oz for the nontreated control to 6.70 oz for Stratego YLD 4.18 SC, 4 fl /oz A. There were no significant differences among treatments for 500-count kernel weights. Grain moisture at harvest ranged from 14.3% to 14.8%. Yields ranged from 267.6 bu/A for Domark 1.9 ME, 4 fl oz/A to 280.7 bu/A for Aproach 2.08 SC, 6 fl oz/A. The nontreated control yielded 275.2 bu/A. There were no significant differences among treatments for grain moisture percentage or yield.
