While corn planting progress is way ahead of the miserable 2019 planting season, Indiana’s corn crop has already experienced more than its fair share of misery.

Wheat has greened up and is actively growing across Indiana (except during these last few cold spells).
Planting has begun to ramp up here in Indiana. I want to remind you of a few resources for monitoring field crop diseases.
Each year the members of the Corn Disease Working Group and the North Central Regional Committee on Soybean Diseases (NCERA 127) with the support of the United Soybean Board establish ratings on the efficacy of fungicides for corn and soybean diseases.
Tar spot of corn has been a concern this season after the localized epidemics we experienced last year in Indiana.
The time has come to start scouting corn for ear and stalk rots. This will aid in making assessments about field harvest order and if there is a risk of mycotoxin contamination.
Soybeans We are starting to see a number of diseases in soybean across Indiana. This week in our plots in both northern and southern Indiana initial foliar symptoms of sudden death syndrome are making an appearance. In addition, we continue to see frogeye leaf spot and Septoria brown spot – the levels of both of these diseases were very low and our soybean are about R4 (beginning pod) to R5 (full pod). I suspect that if we continue to receive intermittent rain, we might start to see a bit more disease in soybean. Corn Tar Spot – We have confirmed 11 counties with active tar spot as of August 28 for the 2019 season. These counties all had a previous history: Elkhart, Jasper, Kosciusko, La Porte, Lagrange, Lake, Marshall, Noble, Porter, Pulaski, and St. Joseph (figure 1). I have included the 2018 tar spot map from Indiana for your reference[Read More…]
