Disease Severity and Yield of Sweet Corn Hybrids with Resistance to Northern Leaf Blight
Northern leaf blight (NLB), caused by Exserohilum turcicum (Pass.) K. J. Leonard & E. G. Suggs), is a prevalent disease of sweet corn (Zea mays L.) in the United States. Fungicides are used routinely to prevent severe epidemics of NLB on nearly 20,000 ha of supersweet (sh2) hybrids grown each spring in southern and central Florida. Epidemics of NLB on sweet corn grown in the midwestern United S...

متن کاملReactions of Sweet Corn Hybrids with Resistance to Maize Dwarf Mosaic
Yield and ear quality of sweet corn (Zea mays L.) can be reduced by maize dwarf mosaic (MDM). When Janson and Ellett (6) first reported the disease from southern Ohio, they observed nearly total losses in fields of late-planted sweet corn. Yield reduction due to MDM and symptom expression are affected by the growth stage at which sweet corn is infected (5,12, 18,25). When late plantings of swee...
