Carl Bradley, J.D. Green, John Grove, Greg Halich, Erin Haramoto, Cam Kenimer, Carrie Knott, Chad Lee, Travis Legleiter, Sam McNeill, Michael Montross, Hanna Poffenbarger, Dan Quinn, Edwin Ritchey, Montse Salmeron, Jordan Shockley, Tim Stombaugh, Raul Villanueva, Ole Wendroth, Kiersten Wise | Dec. 13, 2022 (Major Revision)
Corn is a summer annual crop that is grown widely across Kentucky, the United States, and around the world. In the United States, field corn is grown on about 85 million acres (34 million hectares) while sweet corn is grown on about 600,000 acres (240,000 hectares) and popcorn is grown on about 200,000 acres (81,000 hectares). Most of the field corn across the United States is yellow dent corn. In Kentucky, both yellow dent corn and white dent corn are grown. Corn acres in Kentucky peaked at 3.85 million in 1917 and have been around 1.2 to 1.5 million acres since the 1970s (USDA-NASS, 2020). Most corn in Kentucky today is grown in minimum tillage or no-tillage conditions. Most corn acres are rotated with soybean or wheat and double-crop soybeans.
PPFS-AG-C-2: Seedling Diseases of Corn
Carl Bradley, Kiersten Wise | Mar. 8, 2021 (Major Revision)
Corn seeds and seedlings are susceptible to infection by a number of soilborne fungi. When planted into cool, wet soils, seeds may decay before or after germination. Affected plants that survive past the seedling stage may go on to produce an ear if nodal roots develop normally, although stunting and reduced ear size can occur as a result of seedling diseases. Severely affected plants may die during stressful weather as the result of an inadequate root system.
PPFS-AG-C-10: Northern Corn Leaf Blight
Nolan Anderson, Carl Bradley, Kiersten Wise | Feb. 15, 2021 (New)
Northern corn leaf blight (NCLB) is a significant foliar corn disease in Kentucky. This disease has been damaging in the United States Corn Belt since the early 1900s, but has increased in severity and prevalence throughout the U.S., including Kentucky. This publication describes the symptoms and signs of NCLB, conditions that favor disease development, and management methods to reduce impact on yield.

PPFS-AG-C-9: Curvularia Leaf Spot
Nolan Anderson, Carl Bradley, Kelsey Mehl, Kiersten Wise | Jul. 1, 2019 (New)
Curvularia leaf spot is a corn disease that was reported for the first time in the United States in Louisiana in 2017, and was confirmed in Kentucky in 2018. While the impact of Curvularia leaf spot in Kentucky is not yet known, this disease causes yield loss in tropical areas, and is considered to be one of the most important diseases of corn in China. This publication describes the symptoms and cause of disease, conditions that favor disease development, and foliar diseases that have similar symptoms.
PPFS-AG-C-8: Diplodia Leaf Streak
Nolan Anderson, Carl Bradley, Kelsey Mehl, Kiersten Wise | Sep. 1, 2018 (New)
Diplodia leaf streak of corn is a disease that has become more prevalent in Kentucky in recent years. It is commonly observed in fields in western Kentucky and is easily confused with other corn foliar diseases. Small, round, dark brown-to-tan lesions are first observed on leaves. Dark concentric rings may be observed in the center of early lesions at the infection site on the leaf. These lesions expand lengthwise in long streaks from the infection point and form elongated elliptical lesions. In severe cases, lesions can coalesce to blight large areas of affected leaves.
PPFS-GEN-16: Southern Blight
Carl Bradley, Emily Pfeufer, Nicole Ward Gauthier | Aug. 1, 2018 (New)
Southern blight affects hundreds of different plants, including vegetables, field crops, ornamentals, and fruit. This disease is also known as southern stem blight, basal stem rot, Sclerotium blight, crown rot, and white mold (not to be confused with Sclerotinia white mold). Depending on host plant, production system, and environmental conditions, the severity of this disease can vary from a minor problem on isolated plants to extensive damage causing significant crop losses.
ID-249: A Comprehensive Guide to Soybean Management in Kentucky
Ric Bessin, Carl Bradley, J.D. Green, John Grove, Greg Halich, Erin Haramoto, Carrie Knott, Chad Lee, Travis Legleiter, Josh McGrath, Sam McNeill, Javier Reyes, Edwin Ritchey, Montse Salmeron, Jordan Shockley, Claire Venard, Raul Villanueva, Ole Wendroth, Kiersten Wise, Xi Zhang | Jun. 7, 2018 (New)
This publication provides information on soybean growth and development, principles of variety selection, and management practices to maximize soybean profitability in Kentucky.
PPFS-AG-C-7: Physoderma Brown Spot
Carl Bradley, Brenda Kennedy, Kelsey Mehl, Kiersten Wise | Feb. 1, 2018 (New)
Physoderma brown spot can be a striking foliar disease that is periodically observed in field corn in Kentucky. This publication describes the symptoms and cause of disease, conditions that favor disease development, and options for disease management.
