This Week’s Agronomy: Disease in the Midwest

This Week’s Agronomy.

This week’s topic brings in diseases, which have been popping up all over in the Midwest. If you’ve been outside at all the past few weeks, you’ve noticed it has been hot and humid! Humidity speeds up plant diseases from fungal spores, as spores require moisture to grow and develop.

Note from our staff: We have heard reports that more and more bacterial diseases are showing up across the Corn Belt, as well.

Diseases can come from a variety of vectors and conditions. The biggest key to protection against these diseases is to understand the history of past issues in a field. This tied with rotation can help protect against many diseases. Choosing hybrids/varieties that are more tolerant/resistant to a field with a history of a disease is effective, as well as understanding EXACTLY what the disease is. I have seen a few misdiagnosed diseases already this year, and a disease that is identified incorrectly may be treated with something that is ineffective. Before using a curative fungicide, make sure the disease can be treated with a fungicide! Fungicides are not effective on bacterial diseases, such as Goss’s Wilt. Another big key into disease management is ensuring proper nutrition through fertility, a healthy plant starts with what it eats – and plants drink their food from the soil-water solution.

Below you’ll find a quick article that shows the differences between bacterial and viral agents that can cause diseases in plants.
