PPFS-AG-C-5: Diplodia Ear Rot

Carl Bradley, Kelsey Mehl, Kiersten Wise | Oct. 11, 2017 (New)

Diplodia ear rot can reduce yield and grain quality by damaging kernels, lowering grain test weight, and reducing grain fill. Incidence of affected ears in the field can vary from 1% or 2% to as high as 80%. Although mycotoxins have been associated with Diplodia ear rot in South America and South Africa, there have been no reports of livestock feeding issues due to mycotoxins linked to Diplodia ear rot in the United States.

Grain sorghum can be used for a variety of purposes including animal feed, unleavened breads, cakes, wallboard, starch, dextrose, brooms, ethanol, high quality wax, and alcoholic beverages. Grain sorghum produced in Kentucky is most commonly used for animal feed and was first grown here in the 1920s. Although acreage in Kentucky has fluctuated considerably over the years, yields have generally exceeded the national average since the 1970s, indicating that grain sorghum is an option for producers interested in diversifying grain crop operations.
