Over the last few days, many farmers in Ohio and eastern Indiana have noticed some patches or large areas that appear to be wilting, turning yellow or brown, and dying. Below are just a few photos of the symptoms we are seeing.

A large percentage of Ohio’s corn acres were put in the ground over the last few weeks. Since then, the warm temperatures have caused corn to emerge rather quickly, in approximately five days vs. the April planted corn which, in some cases, took up to three weeks! As our customers are out scouting their fields, several of them have noticed a reduced stand and wondering what the causes might have been...

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.

Was there any effect on the wheat crop as a result of the cold temperatures from last weekend? As I have been looking at wheat fields throughout Ohio this past week, I was worried the cold temperatures might have frozen some of the developing wheat heads. I was especially concerned for areas in southern Ohio where the wheat was further along.

Many areas of Ohio received record low temperatures on the morning of April 24. Temperatures dropped into the mid-20s in several areas of northern Ohio, while shattering previous lows by 5-7ºF in parts of central and southern Ohio (London for example). Many farmers may be wondering what (if any) effect will this have on their wheat crop. The extent of damage you may see will vary based on a few factors such as: the stage of growth of your wheat crop, the variety planted, maturity, planting date, planting depth, and temperature.
Let’s discuss each of these in a little more detail.

Last week I met our regional product specialist, Mark Apelt, at L & S wheat plot in Pandora, OH to revisit our initial wheat evaluation from earlier this spring. The wheat is now greened up, however, some fields that looked great when we first scouted them in late March now have parts of the field that are now dead. The question is, “why?”

Every year there are some soybean fields where the stems stay green while the soybeans are mature and at the ideal moisture. Sometimes the leaves fall off the plant and sometimes they remain green and stay on. The one common symptom for most cases (except fungicides and genetics) is that there is not a heavy pod load on the plant. There are numerous factors that can cause a less than ideal pod load. In this article are just a few items that may contribute to green stem.

Most areas of Ohio and Indiana are in or have finished pollination. Some areas are past brown silk and are in the milk stage. Northern Corn Leaf Blight (NCLB) continues to spread and can easily be found in many fields in Indiana and Ohio. Is it worthwhile to spray for this disease this late?

The last year we had a significant amount of white mold pressure was 2009. As you may (or may not) recall, 2009 was below average as far as temperatures were concerned. Highs were generally in the 70s and low 80s and lows were in the 50s and 60s during July. When we look at July 2014 so far, we are following a similar pattern.
Soybean Fungicides: Are they worth it?
We are approaching or are at the R3 stage of soybeans in many fields. The R3 stage is when there are pods developing on the lower nodes (there still will be flowers on the upper nodes as the stages in soybeans overlap). As a general rule, most fungicides are recommended at the R3 stage of growth. The question is, are they worth it?
Checking for Successful Pollination
Many areas are just beginning pollination while many other areas are completing pollination. How successful has pollination been this year? An easy way to determine is to do the shake test.

Corn Disease Update
Last week we reported that Gray Leaf Spot was being found in many corn fields. This week there is Northern Corn Leaf Blight (NCLB) moving into some areas, especially those areas that had a rain early last week.
The next few days are forecast to be well below average for temperatures. Usually this time of year we are talking about heat and drought and its effect on pollination.
Although soybeans appear to be improving, there are still some areas where soybeans are staying yellow. Most of this yellowing has to do with water tolerance.
Most growers in our area have harvested wheat this year and many were surprised by how good the yields were. With the colder than normal winter and warmer than normal temperatures during grain fill, why were the yields so good?

In the past week I have started to see some corn leaf diseases, specifically Gray leaf spot (GLS), in many corn fields. The GLS has been seen in both both corn/corn on corn after soybean rotations. The picture below was taken from a field that was corn after soybeans and was not pollinating yet. As you can see there was plenty of disease on this leaf.

With all the rain we have received in certain areas there have been several farmers who have not had the opportunity to apply their post emerge herbicides. Many fields have giant ragweed and marestail escapes. Let’s talk about options for each.

During the past there has been much discussion and research regarding the ideal planting depth for corn. Surprisingly, there has been relatively little research done on the ideal planting depth for soybeans. If you do a web search for ideal planting depth of soybeans the results will vary from as shallow as ¾” deep to <2.5” deep. That is quite a range!

While driving through Indiana and Ohio there are many soybean fields that are pale yellow in color. We have had adequate moisture and above average temperatures, so what is going on?
Rapid Growth Syndrome
Recently, there have been a few reports of corn that looks like it is getting wrapped up in itself. This is known as rapid growth syndrome or some call it twisted whorl syndrome.
There have been a few reports of corn that is leaning over after storms from last Wednesday. Genetics do not seem to play a role as many companies and hybrids have shown this symptom.

In the past week there have been reports of fields having plants that are dying. The plants below are a good example of what is being seen. The symptoms range from plants not growing or appearing to shrink since surrounding plants are growing, to the whorl of the plant being yellow or brown, and the lowest leaves being a dark green; to totally dead plants.

Why do my soybeans look like they are dying? This week we have had numerous reports throughout Ohio, Indiana, Illinois and Kentucky regarding soybeans that are not looking as healthy as we like. The majority of soybeans have the outside of the cotyledons that look brown as well as the hypocotyl, especially when in the neck stage. This appears to be happening to all varieties from all companies, so it is not product specific.

According to NASS, there were 4.6 and 5.6 days suitable for field work in Ohio and Indiana, respectively. Several areas in both states received greater than 2” of rain this past weekend and water was ponding in several fields.
We need to be on the lookout for black cutworms cutting plants in the next week or so. Black cutworms do not overwinter in Ohio or Indiana but are blown in on storm fronts in April and May.

Should I Be Planting Yet?
The calendar says we should be planting, the soil moisture level in many areas says we should be planting, but the forecast calls for cool weather into next week.
How Deep Should I Plant Corn?
As mentioned in the previous article, the weather is predicted to stay below normal for the next week. If you decide to plant, should you plant shallower due to the colder weather?

How long do I wait between applying anhydrous ammonia and planting?
Based on how the 2014 season is shaping up so far, we will be doing many field activities all at once. One question on many farmers mind is “How long do I need to wait between applying anhydrous (NH3) and planting?”
Uniform Seed Spacing for Maximum Yield-- How important is uniform seed spacing?
According to research from Purdue University-very important! Purdue looked at plant to plant spacing over a 6 year period and measured yield loss. They measured the plant to plant distance over a 30 foot area in 2-3 areas of a field.
