Agronomy Update

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: 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.
