Corn and Soybean Replant Decisions

May 24, 2017 by Brian Weihmeir
This year has been a tough one for areas of the Midwest. Cool and wet weather since planting has left fields with lower than desirable stands and ponded areas. With some areas sitting idle due to Mother Nature, growers have had the time to look at their fields and evaluate their stands. Depending on their planting rate and other factors, some...

Vomitoxin

May 22, 2017 by Greg Peters
Ear molds were a common problem in 2016 because of high rainfall that occurred as ears of corn were developing.  Usually these molds don’t cause too much of a problem because the infected kernels blow over the shoe of the combine if fan speeds are increased.  It is also recommended that grain that is going to be stored from fields...

Temporary Early Season Nutrient Deficiencies in Corn

May 11, 2017 by Leonard Luebker
How can there be an early season nutrient deficiency, if the soil test shows everything is good?  Early season nutrient deficiencies, may occur in corn, whether one sees the deficiency or not.  Nutrient usage by corn plants, requires a healthy, growing root system.  ? Emerging corn: This corn was...

Early Frost Damage in Corn

May 9, 2017 by Matt Teply
Having lived in SW Nebraska most of my life, I have unfortunately been in more than my fair share of corn fields that have had a frost or a freeze after corn has emerged.  Freeze damage in corn is often hard to evaluate the day after it happens.  Especially in a crop that is maybe just at the V1 to V4 leaf stage. Most of the time there...

Purple Leaves in Corn

May 4, 2017 by Steve Crafton
A fair amount of corn has been planted across the Corn Belt the past few weeks.  Spring rains have been ample across the Corn Belt and temperatures are expected to drop into the lower 40’s again this week. It would not surprise me to hear reports of farmers seeing reddish-purple leaves in their young corn plants. Cool conditions, soil...

Ponding Effects on Early Stage Corn

Apr 28, 2017 by Matt Teply
With the recent weather and the 14 day forecast of continued wet and cooler weather there are going to be areas of ponding or standing water in corn fields.  Being from Western Nebraska we see ponding in corn fields but it is normally man made, irrigation, and expected.  But, every now and then we get a toad drownder of a rain and we...

Black Cutworm and Armyworm Moths Making Early Arrivals in 2017

Apr 24, 2017 by Jesse Grogan
A mild winter and spring storm activity are increasing the incidence of migratory insect pests such as the black cutworm and armyworm moths. These are sporadic and nocturnal pests that overwinter in southern states such as Texas and Louisiana are moving north ward as winged adult moths with storm fronts. Adult moths lay eggs in exposed fields on...

Plains East Crop Progress

Apr 24, 2017 by Leonard Luebker
The Plains East Region is spread from Sioux Falls, South Dakota, to St. Joseph, Missouri, with westward movement of that line approximately 100 miles.  Consequently, planting in Northeast Kansas, and Southeast Nebraska, are considerably different than the areas in northern Nebraska, and South Dakota.  Basically the dividing line would be...

Ohio Crop Progress

Apr 24, 2017 by David Benning
The state of Ohio has been hit and miss over the last week, when it comes to planting. The northern half of the state has received more rain which has slowed down their efforts, while southern Ohio kept the planters rolling. To date, the state average for corn planting is 8-10% and soybeans at roughly 5%. A lot of field work has already been...

Southern Illinois and NE Missouri Crop Progress

Apr 24, 2017 by Brian Weihmeir
Here over the past two weeks, farmers have been hitting the ground running to get field work done. Early April, most of the work being done in the region was spraying and secondary tillage. Henbit, Chickweed and other winter annual weeds are becoming a real issue for growers in central Illinois due to the favorable fall weather we had to establish...

Plains West Crop Progress

Apr 24, 2017 by Matt Teply
Southwest Missouri:   Weather had been cooperating until this past week.  60% to 70% of the corn crop is in the ground and then wet weather set in.  Soil conditions were very favorable and corn was emerging in 7 to 10 days after being put in the ground. ...

Eastern Iowa Crop Progress

Apr 24, 2017 by Ryan Dunsbergen
The majority of the alfalfa fields in Eastern Iowa recovered nicely from the winter.  Based on the winter we had, I was curious to see how well they would break dormancy this spring.  On the one hand, we had a rather mild winter.  However, with the inconsistent snow cover and several days of temperatures bumping above freezing, I...

Western Iowa and Missouri Crop Progress

Apr 24, 2017 by Greg Peters
Above normal temperatures in March made it look as though the spring planting of 2017 would progress at an extremely rapid pace.  Soil temperatures warmed rapidly and most spring applications of ammonia were done early.  Producers were waiting for insurance dates to start planting or in some cases, rainfall, because of areas that were...

Northern Illinois Crop Progress

Apr 24, 2017 by Steve Crafton
It’s been a cool wet start to our planting season in Northern Illinois.  Not much has been done in our Northern tier but over the past week or so the Southern tier of counties farmers have been running hard.  I would say from Western Illinois over East not quite to the Indiana border corn is probably 35% planted and soybeans are...

Minnesota and Wisconsin Crop Progress

Apr 24, 2017 by Logan Vaughn
As we enter the week of April 24th there has been very little corn planting progress due to wet conditions across Minnesota and Wisconsin. There were favorable weather conditions over this past weekend that allowed some areas to plant but the upcoming five day forecast is predicting a cold front along with more rain, that will likely limit...

Indiana and Mid-South Crop Progress

Apr 24, 2017 by Jesse Grogan
Field activity is brisk in recent weeks. Above average temperatures and dry conditions in many areas allowed for significant field work such as anhydrous ammonia and fertilizer applications including burn down weed control and cover crop elimination. Planters are rolling in the south and beginning to move in central and northern Indiana. Planting...

Avoid Chilling Injury in Corn

Apr 14, 2017 by Ryan Dunsbergen
What once looked like an early, dry spring in the Upper Midwest has now quickly become a possible late, wet spring.  For those still holding 2016 grain, the benefit might be better prices.  I have heard from a couple of marketing advisors that any type of weather scare should cause a rally in the markets.  However, a wet spring does...

Spring Alfalfa Stand Assessment

Apr 6, 2017 by Logan Vaughn
Growers are currently preparing for spring seeding of alfalfa throughout the Midwest. A major focus prior to seeding is the evaluation of existing stands for winter injury and assessing the need for replacement.  This technical bulletin will review our current situation, discuss steps to evaluate your stands this spring and provide management...

ILeVO®, PPO Herbicide & Seedling Disease Injury Symptoms

Apr 1, 2017 by Travis Dollarhide
Two weeks ago Steve Crafton did an article for this blog on ILeVO® seed treatment. This is a follow up article to provide the resources to dig a little deeper to distinguish between ILeVO, PPO herbicide injury and the seedling diseases that can occur at emergence. This year the LG Seeds soybean plot seed is treated with AgriShield® F...

Liberty® Herbicide Works to Controls Weeds

Mar 25, 2017 by Mark Seem
There are weeds that have producers moving from a glyphosate weed control program to a glufosinate weed control program.  Glufosinate is the active ingredient in Liberty® herbicide. This switch has been forced by the spread of glyphosate resistant weeds due to continual and repetitive use of only glyphosate across wide geographies of the...
