Fusarium Head Blight (FHB), also called head scab, is a disease that can affect many small grain crops, but its economic impact is the largest on wheat. The causal pathogen of this disease is Fusarium graminearum, and it can significantly impact yield and grain quality. The disease can produce many mycotoxins. Deoxynivalenol (DON), also known as vomitoxin, is the primary mycotoxin screened for at grain delivery points.

There are many reasons a corn crop may fail. In some years it’s a late frost and in others, soil surface crusting. Regardless of the reason the stand fails, it is important to destroy the original crop before replanting. Yield losses can occur if just 5,000 of the original corn plants remain to compete with the new stand. Therefore, it is imperative to successfully eradicate as much of the existing stand as possible.

Can you pick a palmer from a redroot?
Weeds are off to the races this season and the first, and most important step to controlling broadleaf weeds is correct identification.

Most farmers are aware of the "Time of Day Effect" when it comes to applying Liberty® herbicide on LibertyLink® soybeans.
I recently attended Dr. Larry Steckel's University of Tennessee Weed Tour and I wanted to give you an update on a few of the new herbicide programs that are coming out that can be used in double crop or high biomass situations.
Check out the video below to see the difference in residual formulations from this cover crop termination study.

When scouting fields over the last few weeks I have seen a number of weeds popping up in corn and soybean fields across Beck's southern marketing area.
Did this year's freezing temperatures affect your yield potential?
While total wheat acres are down this year due to commodity prices, there there are still several thousand acres of Beck’s wheat planted throughout the South.
Unfortunately, that wheat has had a very troubled start this season. During planting, we experienced several weeks of dry weather that slowed emergence and even delayed planting. Then, in early January, we experienced two weather events that brought below normal temperatures (single digits in some areas) for extended periods of time. I have had several concerned farmers call and ask me if these weather events damaged their wheat crop and, true to my agronomist nature, my answer has been, “it depends on several factors.”

I feel like this year has been a big set up. We had excellent planting conditions in late March and early April, and we were able to get a lot of crops planted. Then Mother Nature took a turn for the worst, and the following three weeks were cold, wet, and cloudy. Much of our corn struggled to emerge and lacked the early season vigor I would typically like to see. However, we were only accumulating five to ten growing degree units (GDUs) per day, so it was somewhat expected. Seed treated with Beck’s Escalate™ yield enhancement system really had an advantage this year! Now that the weather has warmed up and we’ve started seeing the sun again, the corn that wasn’t underwater for too long is starting to look much better. Most of my service calls recently have been in regards to soybeans, or really the lack thereof. Even though each field has the potential to be completely different, I have started to notice a pattern. There have been two major culprits of soybean loss this year: PPO or Group 14 herbicides (especially in soybeans that were treated with ILeVo®) and slugs.

Over the past few weeks, I've observed a high amount of soybean slug damage that has become a problem as of late.
These slugs actually eat soybean plants as they come up through the ground and because common insecticides are not active on them, they have the potential to cause yield loss.
Back in March, a majority of my territory experienced a freeze event. And while our wheat grew out of it and was looking very healthy, we are now seeing some damage.
Many parts of Indiana, Missouri, and Kentucky have received over 4 in. of rain in a very short amount of time which has caused severe flooding in some areas. Because of this, I have received a number of questions from farmers wondering how long corn can survive under water and how much of their nitrogen (N) will still be there when the water finally recedes.
Much of the wheat throughout my territory is now between Feekes 10 (head in boot) and Feekes 10.1 (grain head visible). This means that within the next two weeks, it will be time to start making fungicide applications to protect our wheat against Fusarium head blight (head scab).

Do you know what the most abundant element in the air is? It’s not oxygen. It’s not hydrogen. It’s actually nitrogen (N). That’s right, one of the biggest input costs on your farm is actually floating around in the air you’re breathing. But since it’s a diatomic molecule (N2=gas), your corn crop can’t access it. Therefore, you have to buy and apply it to your crop. Soybeans, on the other hand, are legumes which means they can capture that free-floating N gas and, with the help of some soil microbes, convert it to a usable form of N.
If you haven’t already started planting, I’m sure you will be soon. Let’s quickly discuss the unseasonably warm temperatures we had this winter and why it has me concerned for this growing season. We rely on sub-freezing temperatures to eliminate many disease pathogens and insects that overwinter in our fields

We are at the start of another challenging year with low commodity prices and shrinking margins. To succeed in a down market, we have to set ourselves up for success from the start. The best way to do that is to utilize all of your tools to their fullest potential. That means making sure your planter is ready for the field before it’s time to plant. Accuracy of plant spacing, seed depth, and seed-to-soil contact are the keys to achieving a picket fence stand and maximizing a crop’s yield potential. Below is a list of things to check before you pull out of the shop.

God willing, planters will be rolling through fields within the next four to five weeks. If you haven’t already, now is the time to start thinking about burndown options. We’ve had a very mild winter (as you can tell by the size of our wheat!) and many winter annuals have grown much larger than usual. This should be taken into consideration when thinking about those hard-to-control winter weeds like Italian ryegrass and marestail.

Cover crop acres have been steadily on the rise for the last few years. According to a recent survey by the Sustainable Agriculture Research and Education Department, farmers in the U.S. increased their cover crop acres by 147 percent from 2014 to 2016. But, this rapid adoption did not come without growing pains. Many farmers have struggled with terminating their cover crops on time and, in many cases, the cover crop persisted into the growing season and actually became detrimental to yield.

According to a recent survey by the Sustainable Agriculture Research and Education Department, farmers in the U.S. increased their cover crop acres by 147 percent from 2014 to 2016. But, this rapid adoption did not arise without growing pains. Many farmers have struggled with terminating their cover crops on time and, in many cases, the cover crop persisted into the growing season and actually became detrimental to yield. How and when you should kill your cover crop will be dependent on the cash crop you’re planting as well as the species and growth stage of your cover crop.
Many farmers are using cereal crops (cereal rye, wheat, etc.) as a part of their mixture because of their relatively low cost and ability to produce biomass above and below ground. Soybeans have a greater ability to overcome cereal competition early in the year so termination can be delayed up to 7 to 14 days after planting. Corn lacks the early season “grit” that soybeans have and thus, the cereal cover should be terminated at least 14 days ahead of planting. University of Tennessee Weed Scientists Dr. Garret Montgomery and Dr. Larry Steckel have seen a negative impact on corn stands and early season vigor when a standalone cereal cover crop was used. However, when a legume (vetch) was introduced to the mix, a significant difference in vigor was seen (Figure 1).
