Plains West Crop Progress

Sep 26, 2016 by Matt Teply
Southwest Missouri:   Corn harvest is about 85% to 90% complete.  The biggest hold up now is storage.  Elevators are full up with wheat and corn. Thus limiting the corn take on a day to day basis.  Yields for most of this region have been average to slightly...

Plains East Crop Progress

Sep 26, 2016 by Leonard Luebker
A small amount of harvesting has occurred in the Plains East Region. A lot more will be known in another week or two.  Rain over the weekend put any harvesting to a halt. The little information we have to this point, is from a few plots, and feedback from field harvesting that has occurred. South of Lincoln Nebraska in a dry area, one corn...

Western Iowa and Missouri Crop Progress

Sep 26, 2016 by Greg Peters
Harvest is underway in our area with harvest progression varying in different areas.  Central Missouri has been harvesting corn for a few weeks and combines have just begun to roll in other areas on either corn or soybeans.  Corn maturity and dry down has varied depending on whether or not disease pathogens are present, or when they...

Dead Plants or Dead Areas in your Soybean Field?

Sep 15, 2016 by Leonard Luebker
What does this mean? A dead area in a field.   First of all, a dead area in a soybean field with DEAD LEAVES attached, means the plants died early. This is most likely due to a soybean disease.  Areas die, and are noticeable usually a week or two ahead of the main part of the field. ...

Bacterial Leaf Streak in Corn

Sep 9, 2016 by Matt Teply
Over the past few months I have received many pictures and texts with issues of damage to leaf tissue in corn.  This leaf blight has been readily seen in much of Nebraska, Kansas, and Colorado.   Bacterial Leaf Streak disease is caused by Xanthomonas vasicola  pv. vasculorum.  The disease has now...

Anthracnose Top Die Back of Corn

Sep 2, 2016 by Jesse Grogan
Anthracnose “top die back” is a disease observed in the weeks prior to harvest. It is caused by the fungal pathogen Colletotrichum gramincola. Symptoms are dying and dead leaves at the top the plant with a green leaf section above the ear and dead or dying leaves below the ear. It should not be confused with dying leaves of...

Diplodia Ear Rot

Sep 2, 2016 by Steve Crafton
Diplodia ear rot is caused by the fungus Stenocarpella maydis.  It has been diagnosed in several corn fields in Illinois this year.  This is a tough fungus to manage because weather plays a big factor on infection.  Once it has been diagnosed, handling of the grain needs to be considered especially if the crop will be put...

Bean Leaf Beetles

Aug 26, 2016 by Greg Peters
An increase in population has been observed this season because of the mild winter of 2015 - 2016.  The bean leaf beetle overwinters as an adult and most adults overwinter in areas with high residue such as timbers, pastures or waterways by burying themselves under the plant debris.  We have been fortunate the past few prior production...

Japanese Beetle in Soybean

Aug 26, 2016 by Ryan Dunsbergen
Japanese beetle populations have continued to increase over the past several years.  This year, especially, there has been increased feeding from this pest.  Weather patterns have played a significant role in their expansion.  Mild winters, early planting and adequate soil moisture are conditions that favor the continued success of...

Soybean Aphids

Aug 19, 2016 by Logan Vaughn
Through the first weeks of August in Minnesota and Wisconsin, soybean aphid levels have been low and remained below threshold from my observations.  It has been a warmer summer with very little stress on the crop with most areas having ample soil moisture. There have been several heavy rain events that can help with washing aphids off of...

Estimating Yields Pre-Harvest

Aug 16, 2016 by Mark Seem
Grain fill of corn and pod fill in soybeans are the main focus of these crops as pollination is complete and the march towards maturation has begun. It is always an interesting conversation around the coffee shops and grain elevators when producers start to predict yields of their crops. USDA is publishing estimates, farm commodity groups are...

Status of the New Herbicide Systems for Soybean Weed Control

Aug 11, 2016 by Travis Dollarhide
Overview of Roundup Ready 2 Xtend™, Enlist, and Balance™ GT Multiple new soybean herbicide technology systems will soon be available to help producers manage the increasing weed pressure from glyphosate resistant weeds. Over the last two weeks, I have attended field days that showcased these products....

Indiana and Mid-South Crop Progress

Aug 9, 2016 by Jesse Grogan
July was warmer than normal. The difference maker is the amount of rainfall. August rains will determine yield for both corn and beans where good potential exists. A couple of ½ to 1 inch rains are needed to finish. Corn maturity varies from dented in early planted to milky stages in late plantings of Indiana. Corn is about ½ milk...

Plains West Crop Progress

Aug 8, 2016 by Matt Teply
Southwest Missouri:   Harvest is not that far away.  Some of the mid to late planted March corn is 10 to 14 days away from harvest.  The earlier planted corn caught the brunt of almost all the poor weather and looks to be some of the poorer corn,...

Plains East Crop Progress

Aug 8, 2016 by Leonard Luebker
Corn:  The corn planted early in Southeast Nebraska and Northeast Kansas is denting.  East Central Nebraska will see denting in 5 to 14 days, depending on when it was planted, or replanted.  The corn fields are relatively healthy with some Southern Rust moving into Northeast Kansas, and Southeast Nebraska. ...

Ohio Crop Progress

Aug 8, 2016 by Cody Kerr
The best way to give an update on crop progress in Ohio is pretty well summed up with one word: variability. Depending on where you travel to in the Buckeye state you are going to encounter a number of different situations. Mostly you are going to hear the same too hot, too dry story. However, there are a few...

Southern Illinois and NE Missouri Crop Progress

Aug 8, 2016 by Brian Weihmeir
As we are starting to move towards the final lap of the growing season, the corn and soybean crop in the region is keeping a fast pace towards the finish line. With consistent rainfall and sunny days, we have seen some tremendous progress from both the corn and soybean crops. The corn crop so far is holding up very nicely in the region. One...

Minnesota and Wisconsin Crop Progress

Aug 8, 2016 by Logan Vaughn
Through the first week of August, crop conditions continue to look very good across Minnesota and Wisconsin. Timely rainfall and warm temperatures have been the theme of the growing season for large areas of the region. While there have been some setbacks from storm damage and excessive moisture during parts of the summer, crops look very good at...

Northern Illinois Crop Progress

Aug 8, 2016 by Steve Crafton
Crops in Northern Illinois look very good!  Weekly rains in most regions and a string of 90 degree days in early June have really kept crops moving along.  I would say corn in our southern and western region is probably 10 days ahead of average for the first part of August. It looks like we will experience some very high yields in our...

Western Iowa and Missouri Crop Progress

Aug 8, 2016 by Greg Peters
The corn crop is progressing towards maturity with a range of hybrids bringing their milk-line down in the south, to hybrids that are in the blister to milk stage in the north.   This range is the result of varied planting dates with late March in the south to late May in the north because of a wet spring.  2016 has not been without...
