Crop Residue Effects and Management

Oct 20, 2017 by Leonard Luebker
One can find many articles and research projects that address crop residue breakdown, effects of crop residue on soil fertility, and overall crop residue management. In general, we have observed minimum and no till practices increasing substantially the past several years.  Not only have there been government rules and regulations to follow,...

Will Corn make Black Layer?

Oct 13, 2017 by Corey Prosser
A concern of many growers with late planted corn, and replanted corn, has been: will the corn reach black layer or physiological maturity? Many growers across the Midwest planted corn late, or had to replant many acres. With the month of May being very wet for many areas, this pushed many growers into June planting dates some even mid to late into...

Diagnosing Lodged Corn

Oct 5, 2017 by Ryan Dunsbergen
In a lot of areas across the Corn Belt we have experienced some significant stress this year.  The more stress the corn plant experiences throughout the year, the greater the chances of seeing lodged corn late in the season.  When lodging happens, it is important to head out to the field and diagnose why the corn lodged.  By having...

Fall Weed Control – Plant Clean, Stay Clean

Oct 5, 2017 by Jesse Grogan
Fall weed control delivers clean, weed free fields in the early spring. Winter annual weeds like marestail, chickweed and henbit; biennial weeds like wild carrot; perennials weeds like dandelion and quackgrass are controlled. Warmer soil temperatures and planting conditions improve in clean fields. Fall emerged marestail, many resistant to...

Eastern Iowa Crop Progress

Oct 2, 2017 by Ryan Dunsbergen
Once again, 2017 was a year different than all the others.  The majority of corn has hit black layer in the southern half of Iowa.  In northern Iowa, most of the early maturity corn has reached black layer while the later maturity corn is at half milk line and will reach maturity in the next week or two.  There are a handful of corn...

Northern Illinois Crop Progress

Oct 2, 2017 by Steve Crafton
If I had to describe 2017 in one word it would be “variable.” We fought another wet spring that led to a bunch of replant, 90 degree temperatures in June, scattered rainfall, 70 degree temperatures in August and 90 degree temperatures in September.  I look for harvest results to be mixed as was the rainfall and...

Western Iowa and Northwest Missouri Crop Progress

Oct 2, 2017 by Greg Peters
Harvest began in mid-September in our area and it has been slow as many must wait for later products to mature.  Early results have surprised producers with exceptional yields in our southern portion of our territory with corn fields averaging over 200 bushels per acre or more.  Corn harvest to the north has been limited but silage...

Southern Illinois and NE Missouri Crop Progress

Oct 2, 2017 by Brian Weihmeir
It is the beginning of October, and things are finally off to a fast start! It is an exciting time of year and the results coming in are also exciting! Corn: For much of the region, activity has been a little slower than usual. Due to a cooler than normal August, it took some time to get...

Indiana and Mid-South Crop Progress

Oct 1, 2017 by Jesse Grogan
Corn yields in the mid-south, southern Indiana, and soybean yields in Indiana, are very good at the beginning of harvest. Weather plays a role in every region but usually for the benefit of better yields at the end of the growing season. A few weeks in August were relatively cool with light to moderate rainfall. September is much warmer and dry....

Western Region - California

Oct 1, 2017 by Phil Miller
On the West Coast harvest is in full swing. California Delta corn growers are are knocking down as many acres as they can each day.  One of our dealers remarked on the exceptional quantity corn grades LG varieties are getting.  So far very little disease has been reported in the area.  A little more dry weather and the late planted...

Plains East Crop Progress

Oct 1, 2017 by Leonard Luebker
Harvest has begun in the Plains East Region.  Corn Harvest:  In the areas of Southeast Nebraska and Northeast Kansas, where corn planting was in the range of April 10th to April 30th, the corn moisture's are in the 15 to 17% range.  As was expected, yields are variable within a given field with...

Plains West Crop Progress

Oct 1, 2017 by Matt Teply
Southwest Missouri:   In most years this area of the region would be close to wrapping up corn harvest.  But, this year is not most years.  Corn harvest is only about 50% completed.  Yields are highly variable.  Some of the early planted corn, late...

Ohio Crop Progress

Oct 1, 2017 by Corey Prosser
Harvest is underway in parts of the Buckeye state, although it has been a relatively slow start. There are many factors that have impacted the delay in harvest for the state. The main factors that have had the largest impact include late planting or replants, and cooler than average temperatures toward the end of the growing season. The eastern...

Minnesota and Wisconsin Crop Progress

Oct 1, 2017 by Tom Greiner
Crop conditions have improved across Minnesota and Wisconsin since August 14 reports. Minnesota Around the July 14th date, we were three weeks behind in total heat units. We have improved substantially with above normal temperatures which came the third week of September. We are currently five to six days behind the five-year...

Trichoderma Ear Rot of Corn

Sep 23, 2017 by Steve Crafton
Looking at corn fields the past few weeks I have noticed some ear rots in a few fields. As I seen the scattered dying discolored husk I assumed it was Diplodia Ear Rot.  When I pulled the husk back the ear was covered with the powdery green mold Trichoderma.

Soybean Technology and Herbicide Systems Review

Sep 16, 2017 by Travis Dollarhide
Glyphosate resistant weeds, especially water hemp and palmer amaranth, are a reality for most producers across the soybean growing areas. If not already, there is no question they soon will be. The purpose of this discussion is not to dive too deep into actual herbicide recommendation, as that is a conversation that must happen on a local level to...

NEMASTRIKE™ and Parasitic Nematodes

Sep 10, 2017 by Mark Seem
Nematodes can be responsible for yield loss in agronomic crops. In corn it is estimated that 10% of a crop’s potential yield is lost to nematode damage. 80% of the corn acres in the United States are infested with nematodes. NEMASTRIKE™ is a new technology to combat these microscopic roundworms. The chemistry behind this technology is...

Bacterial Leaf Streak Disease in Corn – Update

Sep 1, 2017 by Matt Teply
Bacterial Leaf Streak Disease (BLS) is caused by the bacteria Xanthomonas vasicola pv. vasculorum.  The disease was officially confirmed to be present in fields in 2016 and symptoms were again observed during the 2017 growing season. Symptoms of the disease were first observed in fields in Southwest Nebraska in 2014.  Confirmed...

Scouting for Soybean Aphids

Aug 24, 2017 by Brian Weihmeir
As we begin to approach the tail end of the growing season, it has been a popular time for growers to be walking fields and evaluate the crops. This time of year tends to be quiet in regards to issues seen in the field. However, one pest that has been noticed recently in soybean fields in parts of the Midwest has been the soybean aphid. Due to the...

Flower and Pod Abortion of Soybeans

Aug 17, 2017 by Greg Peters
It is not uncommon for the soybean plant to abort flowers and small pods as the soybean plant adjusts to the surrounding environment.  The soybean plant does this by forming abscission layer at the base of the flower of pod resulting in the loss of nutrient flow.  Researchers have tried to figure out why these layers form as well as...
