Abstract
foliar fungicide efficacy trial was conducted at the University of Nebraska-Lincoln South Central Agricultural Laboratory near Clay Center, NE. Dekalb corn hybrid DKC 62-54, rating of “good” (6 out of 9) for gray leaf spot (GLS) and “excellent” (2 out of 9) for common rust (CR), was planted on 3 May in 30-in. rows with a target population of 32,000 plants/A. The trial area was disked with soybean as the previous year’s crop. On 9 May before plant emergence, a herbicide program of Roundup (1 pt/A), Verdict (16 fl oz/A) and Atrazine (1 lb/A) was applied to the trial site. Five treatments and a non-treated control were replicated six times in a randomized complete block design. Each plot was four rows (10 ft) wide by 40 ft in length. . . . Additionally, there were no significant differences among treatments for 500-count kernel weights. Grain moisture at harvest ranged from 15.0% to 15.4%. There were significant differences in yield among all treatments. The nontreated control was the lowest yielding treatment at 238.0 bu/A while Quilt 1.66 SC, 10.5 fl oz/A was the highest yielding treatment at 252.5 bu/A.
