The major components of corn silage as forage are yield or tons per acre with the highest quality. For dairy producers, quality refers to milk produced per ton of corn silage and for beef producers, it is the rate of gain per ton of corn silage. Several factors can impact yield and quality, but the focus of this article is on the impact of various corn diseases on yield and quality of corn silage.
Corn diseases attack the leaf, stalk, and ear. Most of the diseases are caused by fungi; however, there are two bacterial diseases, Goss’s wilt, and bacterial leaf streak, that attack the leaves and bacterial stalk rot that attacks the stalk.
