The spring of 2019 has been nothing but challenging for most Midwest farmers. Because of these challenges, we could see more soybean diseases. Because we experienced plenty of rainfall both before planting and after soybean emergence, certain diseases like phytophthora root and stem rot, brown stem rot, rhizoctonia, brown spot, and white mold could show up in soybean fields. These diseases prefer wet/saturated environments and spells of cool/humid conditions. As a result, crop management throughout the growing season will be key to protecting yield potential.
Diagnosing Diseases
For a disease to exist in corn or soybeans, three things need to be present. There needs to be a 1) a pathogen 2) a host, and 3) a conducive environment. The amount of disease present will depend upon how abundant and severe the pathogen is, how conducive the environment is to disease development, and how susceptible the host is to disease. Here are seven of the best management practices to help you reduce the risk of disease pressure in your fields.

But what if we could take these management tips even further and better control diseases and protect our yield?
New Study Alert: Fungicide Timing - Sequential Applications
For the 2019 growing season, our PFR teams in IN, KY, Central IL, Southern IL, OH, IA, and MO are participating in a new fungicide timing study. The protocol for this study is as follows:
Our end goal for this study is to determine if the use of a fungicide at sequential timings will increase plant health, yield, and profitability and also decrease disease severity. As always, we need to practice good integrated pest management practices to help slow fungicide resistance. Fungicides need to be utilized to help fight crop diseases; they should not be used solely for a yield gain.
We look forward to seeing the results from this new PFR study and sharing them with you all. Hopefully, the results can help improve disease management on your farm.
