Variability on Your Farm Affects Seed Decisions
Once the busy harvest season winds down, many of us reflect on those spots that stuck out in each field. Maybe it was a spot that yielded 80+ on soybeans or 250+ on corn, or maybe it sticks out for the opposite reason.Variability on your farm influences the decisions you make throughout the rest of the year. We consider two types of variability — spatial and temporal — in precision ag.
Spatial variability refers to different patterns in an area or space. This is influenced by physical things that don’t change quickly, such as soil type, texture, structure, depth of topsoil and organic matter. These physical soil properties are directly related to the chemical properties of your soil, including water holding capacity, nutrient availability and buffer capacity. All of them impact yield potential.
Temporal variability in a field refers to the patterns between growth stages and/or seasons. One way this variability is evident is how a hybrid or variety responds to environmental stress. We all have areas within our fields that yield poorly one year and then produce top yields the following year. This is a combination of the underlying soil properties and how the hybrids/varieties respond to environmental conditions. No two seasons are alike!
We understand that no two fields are alike either. Latham’s hallmark FieldXField™ crop planning process helps you choose the right product for each field. As an agronomist, I think of G x E x M why picking products on a field-by-field basis is the #1 thing you can do to set yourself up for the best yield potential.
Temporal and spatial variability are key to understanding whether the yield variability in our field is consistent or inconsistent. Once you know how to categorize those areas, then you can put a variable rate program to work on your farm.
This year we’re piloting the Seed-2-Soil® Advanced Program, which uses several years of yield data alongside soil, imagery, your personal input, and any other available data layers to determine how to treat each of those areas. The power is in the multiple years of yield history. Even if you don’t have several years of yield data, there is still a lot of data we can use to create these areas within each field.
If you have fields that you know would benefit from variable rate management, feel free to call me and we can discuss different options. If you’re thinking about incorporating some precision services on your farm, I would be happy to have that discussion, as well.

Tips for Managing Ear Rot
Ear rot has been present in some corn fields that were harvested this year. These diseases can reduce the quantity and quality of the corn being harvested, and they can also produce mycotoxins that might be harmful to livestock and even humans.
These diseases can continue to cause problems in stored grain unless it is closely monitored and maintained in the best possible condition.
Scouting fields prior to harvest is key to avoiding situations caused by mold. A pre-harvest field check can help farmers to determine: (1) if ear mold is present; (2) what type of mold is present; and (3) how severe the infestation is.
One method you can use when scouting fields for ear rots is to tear back the husks on 100 plants scattered randomly throughout the field. If you find 10% or more of the ears have mold on 25% or more of the ear, that field should be harvested immediately and dried to at least 15% moisture. (NOTE: If you plan to turn in a claim for that field to your crop insurance provider, do that before harvesting. The insurance adjuster may need to see proof of the ear rots in the field as opposed to just seeing it in the stored grain.)
Samples of that grain should be tested to see what mycotoxins, if any, are present. You should then consult with someone like an extension specialist or veterinarian to decide the best method of using that grain.
Corn ear rots and molds are present every year, but the severity and type of infestation is highly weather dependent and greatly depends on the region where the farm is located. Fungal pathogens that cause ear rots will remain in the soil for several years. Crop rotation and heavy tillage may help reduce spore survival. Planting hybrids with traits that provide above-ground insect protection and reduce ear damage might also be beneficial.
If you browse online for other ear mold management practices, you will see it’s suggested to plant hybrids with known tolerance to these diseases. Unfortunately, most companies do very little screening for ear mold pathogens, simply because they are so varied and the instances of severe infestations are so rare. In the case of corn ear rots, the best offense is the best defense! Make time to scout each field for ear rots before harvest.

Ear pinching results from severe stress during the 7 to 10 leaf collar stages (V7-10) may result in reduced numbers of kernel rows. The more stress from the summer dry spell, the more apparent the pinching. This is not hybrid specific as it is effecting several hybrids to the degree of stress the corn was put under.

Harvest is officially underway on soybeans as I received my first harvest report yesterday. Latham’s L 1438 R2 yielded 75 bu/Acre at 14% moisture. With yield reports like this, you can’t help but get excited for #harvest17!
Latham products are set to finish the year strong in Wisconsin. While walking a Latham(R) Corn SuperStrip in Utica, I couldn’t help but notice the consistently large ear size on this LH 5245 VT2PRO. I am excited to see where yields come in this fall.
Another new product I am excited about this year is L 1845 R2X. In both locations, it has excellent standability with lots of pods on lateral branches. It appears to be a great defensive Soybean against White Mold.

It’s silage chopping season here in North Dakota. I’m happy to report that in some areas the yields are exceeding last year’s banner year! Fields under moderate to severe drought stress are showing rapid dry down and, as expected, poorer than average yields.
One thing to note: If your farm experienced early drought followed by average to above average rainfalls, there might be as much as a 3-week delay on maturity.
Pictured here are Latham customers in front of a field of LH 4532/RR LFY. Honestly, this picture doesn’t do justice for how good that crop really looks!

We have been out walking fields looking for potential disease. These soybeans look pretty good, but in spots, it looks like cercospora leaf spot is a possibility. As the plants mature, infected leaves will turn from orange to bronze. Tillage and crop rotation effectively reduce the survival of fungi from season to season.

Although with Sudden Death Syndrome (SDS) infects soybean plants right after germination and emergence, symptoms generally do not appear until mid- to late summer. Future management tactics include: reducing soil compaction; planting fields with a history of SDS towards the end of a planting schedule when soils may be warmer and drier; and testing for the presence of Soybean Cyst Nematodes. Planting tolerant varieties, or avoiding very susceptible varieties, is the most effective way to reduce losses from SDS.

The late-plated soybeans in Wisconsin are finally starting to fill the pods. This plant from a field of L 1845 R2X is one I randomly sampled last week in Watertown, Wisconsin. There are 103 pods on this plant with excellent lateral branching. Wet weather has white mold showing up in places we haven’t seen it before, so this would be a good variety to look at for selecting resistance in 2018.
Eastern North Dakota
Brian McNamee
2017 continues to be a real struggle for growers across my region. We have seen an extensive drought, causing failure of pre-emergence chemicals leading to expansion of resistant weeds into new areas. Then after a seemingly saving amount of rain we observed reduced pollination with poor grain fill. So now what? Well, no we’re seeing disease pressure. Goss’ Wilt is showing up in areas where we have never ever had symptoms before.
The disease went undetected for sometime and spread across the plant very rapidly. We’ll be noting where this disease is present, so we can change hybrid placement in the future. Because this is truly a new event in our area, there will be a bit of a learning as we go. Hopefully, this is the last of our hiccups before harvest!

Some of the earlier corn is 30-40% milk line, nearing full maturation. Heavy dew and high humidity is creating disease pressure from rust, Northern Corn Leaf Blight and Goss’s Wilt. Soybeans are really starting to turn yellow as they are nearing maturity. Some areas in the drought will get better than expected yields thanks to some saving rains! Pictured below is John Latham, Myron Keltgen and Phil Long inspecting LH 5245 VT2 PRO. The soybean picture is L0982R2 on the left half and L1438R2 on the right half.

These pictures were taken last Tuesday in a field of corn near Beltrami, Minn. Samples were taken to NDSU for diagnostics and confirmed Goss’s Wilt. This corn disease was first confirmed in Minnesota 2009, and the first I have seen in my region North of Interstate 94. This disease can be managed by using resistant hybrids, rotating from corn production, using tillage that buries corn residue after harvest, and controlling grassy weeds. Latham has hybrids that are designated as “the boss on Goss,†so be sure to check those out for 2018 planting.

This week’s crop report is a “mixed bag.” The good news is we’ve received moisture, but temperatures have been cooler than normal. The month of August brought lots of cool temperatures, so let’s hope early September is usually warm!

Scouting crops all season long is especially important because different insect and disease pressures become evident at this time of year. Any type of stress greatly enhances the likelihood of opportunistic insects such as corn leaf aphids, European corn borer and army worm to feed upon plants. This week I noticed corn aphids in a field near Estherville.
Central Iowa
Bryan Rohe
It’s that time of year when farmers ask themselves what they can do differently to improve yield for the next season. Seed selection is certainly a major factor – some some might argue it’s the most important consideration – to increasing yield. Soil fertility and reducing weed pressure also are among the Top 10 Tips for increasing yield.
I am encouraging farms to look at hybrids that either have a strong drought score or to plant Genuity® DroughtGard® hybrids from Latham Hi‑Tech Seeds in 2018. The longer you can keep plants alive, the more ability they have to do their job. Health corn dies from the ground up, so I’m sure we’ll see an ROI on fungicides this year due to keeping plants health long enough to finish their jobs.
Good plant health is also key to increasing soybean yields. Sudden Death Syndrome (SDS) is starting to show up in Central Iowa soybean fields. The time is right to start watching any side by sides with ILevo and without ILevo. Also, it is a good time to make notes for future years seed treatment plans if SDS is showing up in your fields.
Soybean product selection is key. Prevention is the best defense against SDS. Soybean Cyst Nematodes (SCN) are associated with SDS. The best way to combat SCN is to plant resistant varieties or avoid susceptible varieties. Be sure to keep Latham IRONCLAD™ soybeans in mind when mapping out which varieties will be used on different fields for 2017.
The time is right to also start noting results from studies using ILeVO treated seed. Latham Seeds’ research staff to conduct 2016 studies using ILeVO treated seed side-by-side with seed that was not treated with ILeVO. We saw an average yield advantage of 3.64 bushels per acre across 26 plots, so ILeVO definitely provided a return on the investment.

Silage harvest is underway near Alta, Iowa.
Producers often ask what the most important characteristics are when selecting corn hybrids for silage or grain. To pick the best hybrids for his situation a farmer should follow 3 basic steps: (1) Consider the end use first; (2) Keep crop rotation in mind; and (3) Minimize yield-limiting factors.

Is this some new type of nurse crop?
This season, across my territory in North Dakota, I have been taken aback by the number of semi-resistant or fully-resistant weeds I have been seeing. I had no idea that marestail was as bad as it is and spread so far west. This particular field is the worst infestation I have ever seen. You can just barely make out the soybeans planted in this field.
A full grown marestail can have upwards of 200,000 seeds per plant. Just think of how many seeds are in this field… Crazy!
This year was the perfect storm for these issues to arise: pre-emergence not working; droughty conditions with slow and poor seed emergence; and periods of late-season rains that produced flushes of all weeds.
This now has the potential to be an epidemic problem not only for this farmer but all the adjacent landowners, as well. It’s going to be a challenge and will have to be monitored especially closely.
Herbicide rotation is important, but mixing herbicides with different sites of action makes weed resistance 83 times less likely to occur. Click here to learn more about weed management, including how and why herbicide resistance occurs.

Congratulations to Latham rep Ryan Skaug of M&R Seed for hosting a successful plot day yesterday in Beltrami, Minnesota! The main topics of discussion among growers in attendance was weed management plus corn and soybean technologies.
Weed management is certainly more challenging! Plants that develop resistance to herbicides are simply following the age-old process of “survival of the fittest.” That’s why seed product selection and herbicide rotation are more important than ever.
