Interpretive Summary:

Technical Abstract: This 27-year summary is of University of Illinois sweet corn nurseries from 1984 to 2010, and includes the reactions of 800 hybrids to eight diseases and three herbicides. Commercially-available and pre-commercial hybrids included 547 shrunken-2 hybrids (317 yellow, 152 bi-color, and 78 white), 117 sugary hybrids (103 yellow, 9 bi-color and 5 white), 130 sugary enhancer hybrids (25 yellow, 73 bi-color, 30 white, and 2 red), and 6 brittle hybrids (5 yellow and 1 white). Diseases of interest include common rust (Puccinia sorghi), northern leaf blight (Exserohilum turcicum), Stewart's bacterial wilt (Erwinia stewartii), maize dwarf mosaic (naize dwarf mosaic and sugarcane mosaic viruses), southern leaf blight (Bipolaris maydis), southern rust (Puccinia polysora), anthracnose leaf blight (Colletotrichum graminicola), and gray leaf spot (Cercospora zeae-maydis). Injury to hybrids from various, P450-metabolized, postemergence herbicides have been evaluated in the nurseries since 2002. Only responses to nicosulfuron, mesotrione, and tembotrione are reported.
