Japanese Beetles

Jul 14, 2017 by Mark Seem
Japanese beetles are appearing in great numbers in cornfields throughout portions of the Corn Belt. Normally these pesky insects are not an economic threat to the corn or soybean crops. When winters are somewhat milder than normal, a large number of white grubs survive allowing for a substantial population of Japanese beetles. Very early planted,...

Eastern Iowa Crop Progress

Jul 10, 2017 by Ryan Dunsbergen
The corn crop in Eastern Iowa, as a whole, is looking really good.   We were very dry during the first half of June.  Several corn fields had plants at the V6 – V8 growth stage that were rolling leaves.  I also saw a lot of corn that had a bluish look to it in the V4 – V5 growth stage.  These corn plants were...

Ohio Crop Progress

Jul 10, 2017 by Corey Prosser
Crops in the Buckeye state have a good amount of variability due to weather and replants mainly. The rain has not let up for many parts of the state as it has been very wet over the past few weeks and looks to stay that way. Some areas of the state received upwards of 6 inches in just 10 days. Looking ahead there is good chance of wet weather...

Green Snap in Corn

Jun 22, 2017 by Travis Dollarhide
This is the time of year when much of the Corn Belt enters one of the most susceptible periods for wind damage to occur. In particular, strong winds during periods of rapid growth can cause green snap in corn. While this type of stalk breakage can occur anywhere in the Corn Belt it is much more common in the fertile, wide open plains of the...

“Floppy” Corn Syndrome

Jun 15, 2017 by Steve Crafton
I have been getting some calls from farmers in west central and east central Illinois about corn that is “falling over.”  I went out to inspect these concerns and just like in 2012 I found corn “falling over “with no roots; or in other words - “Floppy” or “Rootless” corn syndrome.  We...

Relative Meal Value of Soybeans – a new concept

Jun 9, 2017 by Mark Seem
Determining a relative meal value score to differentiate soybean varieties based on their soybean meal value for swine has been introduced by the High Yield PLUS Quality (HY+Q) project that is funded by the Illinois Soybean Check-Off. LG Seeds submitted 223 soybean samples to the HY+Q project in 2016. These were part of a larger sampling and grain...

Nitrogen Loss Due to Saturated Soils and Excessive Rainfall

Jun 9, 2017 by Corey Prosser
A question a lot of farmers have been asking, besides should I replant, is how much nitrogen has been lost due to all the rain? This question is not an easy one to answer due to the fact that there are many factors that impact the amount of nitrogen that could be lost. The type of nitrogen: whether it be Anhydrous Ammonia, Urea, or UAN 28-0-0 or...
