Abstract
A foliar fungicide efficacy trial was conducted at the University of Nebraska-Lincoln South Central Agricultural Laboratory near Clay Center, NE. DeKalb sorghum hybrid DKS 36-06 was planted on 23 May in 30-in. rows with a target population of approximately 120,000 plants/A. The trial area was disked with soybean as the previous year’s crop. Four treatments and a nontreated control were replicated six times in a randomized complete block design. Each plot was four rows (10 ft) wide by 40 ft in length. . . . There were significant differences in GLS AUDPC among treatments. The nontreated control exhibited the largest GLS AUDPC value and Headline 2.09 EC, 6 fl oz/A exhibited the lowest value. Despite the reduction in GLS as measured by AUPDC, there were no significant differences in yield, 1,000-count kernel weight or grain moisture among all treatments. The lack of significant differences may have been primarily due to the low disease severity.
