Frogeye leaf spot (FLS), caused by the pathogen Cercospora sojina, is a common soybean foliar disease of many soybean-producing regions worldwide. In the U.S., the disease is established in southern production regions and has recently become prevalent in the Midwest and Upper Midwest. It’s believed that the range expansion and increased disease severity are caused by widespread planting of susceptible varieties, warmer winter temperatures, and the increased adoption of conservation tillage practices, which, together, lead to increased inoculum levels. FLS does not always cause yield loss, but yield loss of up to 60% has been reported with severe infection rates.

After a slow start to the 2016 harvest, farmers throughout Ohio are now in full swing. Harvest marks the final stage to our 2016 crop, it is also the first step in preparing for your 2017 crop. Sitting in the combine at harvest is the perfect time to evaluate the various inputs and practices we implemented throughout the past growing season.

I have received a number of calls from customers over the past few weeks, so I wanted to provide some updates on a few of the hot topics as we continue to monitor the development of our corn and soybean crops.

Protecting corn from yield-robbing pests is one of the greatest concerns for farmers each year. From late June to mid-July these pests include foliar diseases and silk clipping insects. Properly managing these pests is crucial, and we can start by getting a better understanding of the economic and agronomic factors of each specific field.

The cool, wet weather we have been experiencing has lead to increased concern for various threats to our wheat crops. This article includes my updates on what I have been seeing in wheat fields across Ohio over the past few days.

When the combine hits the field, I always feel a sense of accomplishment. On the research farm, harvest is one of the most exciting times of the season. We get to see the results of our hard work come to fruition. During harvest, we remain observant to provide you with agronomic explanations. This season, we will likely see every ditch or change in slope of ground that may have been wet longer. We will take note of this and evaluate how it affects our plots to bring you the most accurate information to help you make better management decisions on your farms! I encourage each of you to do the same on your own fields as you go through harvest.

Wow, what a year 2015 has been! We have now gone from one extreme to the next in areas of southern Illinois. As we enter September and move into harvest, there are some things to take note of out in the field before/as the combine rolls. The biggest observation I have made from the truck is how many weeds are poking up out of fields. This season, some fields did not get timely post applications due to the weather, resulting in waterhemp and other glyphosate resistant weeds rearing their ugly heads. The shining stars this year are the LibertyLink® soybean fields, in particular the fields that had timely pre-applications followed by timely post applications!

In July, nitrogen (N) loss will be apparent in Missouri corn fields due to excessive rainfall from time of application to time of maximum plant uptake. Corn can respond favorably to rescue N all the way to tassel if required (see “Rescue N” article this issue). Don’t leave money on the table if N has become yield limiting. This is also a critical time to make corn fungicide application decisions. Scout fields regularly for signs of corn foliar diseases. Early symptoms don’t always mean a disease will spread and become yield limiting.

In many areas we are looking at corn tasseling or very close to it. Now is the time to evaluate last chance programs to improve yield. The first is fungicide applications. According to our Practical Farm Research (PFR)® data, VT applications on corn have been the most profitable when weather conditions warrant disease development. How susceptible are the hybrids you have planted? Your dealer or seed advisor can walk you through which hybrids will give the best return on fungicide. In soybeans scout for diseases prior to R3 growth stage. If you’ve had wet, or damp conditions in your field and see diseases, look at a fungicide application at R3-R4.

As a kid, I remember my dad and grandpa
saying “knee high by the 4th of July” was
a goal to shoot for with corn. These days,
we have corn tasseling or very close to
tasseling by then if Mother Nature allows
us to get in the field early. So why bring

Another wet spring has provided an ideal environment for diseases. Wheat has already shown the evidence of foliar diseases such as head scab, even where fungicides were applied in a timely manner. The incidence of Pythium on both corn and soybeans, and anthracnose is present in many corn on corn fields in the area.

Every year at this time farmers make the decision “to spray or not spray” their corn fields with fungicide. Understanding all the factors that need to be evaluated before full tassel helps eliminate confusion and hand wringing when the planes are ready and available.
