S. Indiana and E. Indiana: Possibility of Ear Rot - What To Watch For!

Author: Steve Gauck

As harvest starts to approach and we are working to get combines and grain bins ready, don’t forget to keep an eye on your corn fields. Many of us are hoping for a great crop, but as this year continues to look more like the crop of 2009, there are a few things we need to watch.

Is It Too Late to Spray Fungicides on Corn for NCLB?

Author: Mark Apelt

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?

White Mold, Soybean Fungicides, and Pollination

Author: Mark Apelt

White Mold
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, Yellow Soybeans, and Good Wheat Yields

Author: Mark Apelt

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.

Cold Temperatures
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.

Soybean Update
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.

Wheat Yields
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?

E. Indiana and Ohio: Grey Leaf Spot Showing Up in Corn and Soybean Observations

Author: Mark Apelt

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.

E. Indiana and Ohio: Giant Ragweed and Marestail, Brittle Snap of Corn and Yellow Soybeans

Author: Mark Apelt

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.

E.Indiana and Ohio: Results of Planting Depth Study Were Quite Surprising

Author: Mark Apelt

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!

E. Indiana and Ohio: Yellow Beans, Rapid Growth Syndrome, and Floppy Corn

Author: Mark Apelt

Yellow Beans
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.

Floppy Corn
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.

E. Indiana and Ohio: Crop Observations, Pythium, Breaking Necks and Replant in Soybeans

Author: Mark Apelt

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.

E. Indiana and Ohio: Soybean Health and Population

Author: Mark Apelt

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.

E. Indiana and Ohio: Water Ponding, Black Cutworm, and Crop Observations

Author: Mark Apelt

Water Ponding
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.

Black Cutworm
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.

Crop Observations to Date
--- Emergence, temperatures, rotary hoeing and planting time

E. Indiana and Ohio: Nitrogen Loss and Wheat Update

Author: Mark Apelt

How much nitrogen are you losing?
Every year there are questions regarding nitrogen (N) loss from spring storms. This will cause some N loss, but exactly how much is not known. We can take an educated guess by understanding how N reacts in the soil.

Wheat Update
According to NASS, approximately 24% of Ohio and 43% of Indiana’s wheat is jointing. The further north you go, the more behind it is and therefore not jointing yet.

E. Indiana and Ohio: Anhydrous Ammonia Application, Seed Spacing, and Terminating Cover Crops

Author: Mark Apelt

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.
