Diplodia Ear Rot
10/11/2017 (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. | PPFS-AG-C-5

Fungicide Efficacy for Control of Corn Diseases
9/28/2017 (new)

The Corn Disease Working Group (CDWG) developed ratings for how well fungicides control major corn diseases in the United States. The CDWG determined efficacy ratings for each fungicide listed in the table by field testing the materials over multiple years and locations. Ratings are based on the product's level of disease control and does not necessarily reflect yield increases obtained from product application. A product's efficacy depends upon proper application timing, rate, and application method as determined by the product label and overall disease level in the field at the time of application. | PPA-49

Fungicide Efficacy for Control of Wheat Diseases
9/28/2017 (new)

The North Central Regional Committee on Management of Small Grain Diseases (NCERA-184) has developed the following information about fungicide efficacy for the control of certain foliar diseases of wheat for use by the grain production industry in the United States. The efficacy ratings for each fungicide listed in this table were determined by field testing the materials over multiple years and locations by the members of the committee. | PPA-48

Stewart's Wilt of Corn
1/1/2017 (new)

Historically, Stewart's wilt of corn has resulted in losses for corn producers. Although this disease still occurs occasionally, it has become less prevalent in recent years in Kentucky and surrounding states. Stewart's wilt has been known by other names, such as bacterial leaf blight, Stewart's leaf blight, and maize bacteriosis. | PPFS-AG-C-4

Grain Sorghum (Milo) Production in Kentucky
2/8/2016 (new)

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. | ID-234
