To Spray or Not to Spray…Here Are the Answers
By now you should be scouting your fields weekly for signs of disease. Other factors to consider when deciding whether to spray a fungicide include:
- Anticipated environmental conditions. Environment plays a significant role in disease development. Hot, humid weather favors gray leaf spot. Wet, warm (64 to 81°F) conditions favor infection and spore production by the fungus that causes northern leaf blight. Dry weather halts the development of most fungal diseases.
- Planting date. Infection at earlier growth stages will have a greater impact on yield. We usually see gray leaf spot starting on the lower leaves around the end of July and beginning of August. This year corn has been planted at essentially three planting dates. It is possible that the later planted corn (mid-May) will be at a greater risk for yield loss from foliar disease.
- Corn-following-corn fields. Many foliar disease pathogens survive winters in crop residue. Infested residue on the soil surface significantly increases the risk and development of tar spot, gray leaf spot, northern leaf blight and eyespot.
- Fungicide activity. Most fungicides are effective against disease for 14 to 21 days. Corn takes approximately 60 days from silking to physiological maturity, depending on the hybrid. Therefore, spraying a fungicide too early could negate any beneficial effect against disease development that occurs during grain fill.
- Plant health. In the absence of disease, fungicides might only increase yields by five to six bushels per acre. This barely covers the cost of the fungicide plus application.
- Stalk rots. Foliar fungicides will have no direct effect on stalk rots. The fungi that cause stalk rots systemically infect the corn plant, and available fungicides are not systemic enough to be effective against stalk rot pathogens. However, foliar disease severity is highly correlated with stalk rot prevalence. Leaf spot diseases reduce the area of photosynthetic tissue and increase susceptibility to stalk rot. Therefore, fungicide applications may indirectly reduce stalk rots by managing foliar disease and reducing plant stress.
- Tar Spot. Currently, there are multiple fungicides from multiple companies that work to help control tar spot in corn. However, fungicide efficacy is often largely controlled by fungicide timing. In most instances, a fungicide application between the VT growth stage (tassel emergence) and R2 growth stage (blister) is most effective for controlling tar spot. Furthermore, a mixed-mode-of-action fungicide product is often more effective than a single-mode-of-action product. In severe tar spot situations, two fungicide applications may be required. However, this is often dictated by history of severe disease and conducive environmental conditions in a field.
All these points reiterate the importance of tracking disease and continually scouting your field.

Three Keys to High-Yielding Soybeans
Our focus for Latham Premier Agronomy Center in Alexander, Iowa, is to showcase a broad lineup of independent options and to demonstrate how genetics interact with the environment and management styles (G X E X M).

In the Premier Agronomy Center this year, we tested 26 Latham® soybean varieties using 28 different management practices. My top take-home messages for our 2022 soybean plots are:
1. August rains make soybeans. We received 11.8 inches of rain this season but 4.1 inches of it fell in August. Although we received below-normal moisture, the rain came at the right time. Our plots averaged 75 bushels per acre (bu/A) on about 12 total inches of rain!
2. Don’t stress soybeans at early bloom. Weed control in soybeans is extremely important. I made a second pass of Liberty® in season, however, it reduced yields by 10 percent. Our showcase plots did not get the extra dose of herbicide and averaged 86 bu/A; the plots that received a second pass yielded an average of 78 bu/A.
3. “Early” planting date is key to high yield. While earlier is better, “early” does not mean April 10 because we don’t want to risk stand loss to freezing temps. This year our first soybean plots were planted later than expected due to conditions. The plots planted May 13 averaged 5.5 bu/A better than the plots planted May 20. Seven days can make a difference in the number of nodes and pods retained, plus the canopy closes sooner.
The key to higher yields is how all three components – genetics by environment by management – interact. Fertility tops my list, so I always make sure potassium is sufficient. Potassium is what gets soybeans (and corn) through stressful times and helps them better manage water loss on hot days.

Latham® soybeans have outstanding yield potential. But like all living and breathing organisms, our soybeans struggle to perform when they’re stressed at the wrong time. The key to top soybean yields is management: reduce as much stress as possible during the growing season because we can’t control the weather.

Latham’s Premier Agronomy Center Opens for Tours

Latham Hi‑Tech Seeds’ Premier Agronomy Center at our company headquarters in North Iowa provides us with opportunities to collect data on real-world challenges. It also provides us with an opportunity to talk about the exciting new Latham® products, as well as management practices, that help you raise more bushels. This year we have 18 different plots (10 corn and 8 soybean) to demonstrate different techniques.

Interested in seeing Latham’s Premier Agronomy Center? Plan a visit! Latham Dealers are encouraged to make arrangements with their regional sales manager (RSM), so they can bring their customers throughout the growing season. We will be open for public tours on Thursday, Sept. 8, at 4 p.m.

Here’s what you can see inside Latham’s Premier Agronomy Center… As you drive west on 180th Street in Alexander, Iowa, you will see our Latham Showcase plots featuring our top corn and soybean products. Next to that are corn and soybean seed treatment demonstration plots. I also planted my hybrid stress research up front. Twenty different Latham hybrids were planted from 22,000 to 36,000 plants per acre, so we can pinpoint when each hybrid flexes and how we can better manage them in-season.

The second tier of plots contains high-yield plots (corn/beans) where we “throw the kitchen sink at it,” so to speak, to try to add some extra bushels. Our soybean Iron Deficiency Chlorosis (IDC) plot uses tactics like in-furrow chelated iron products with increasing population to overcome the challenges IDC can bring. We have a silage demonstration plot with a planting date demonstration. You’ll also see a sneak peak of Latham’s corn breeding program alongside some great observation plots featuring planting depth.

The third tier of plots are “long-term plots” that include cover crops, no-till and continuous corn. These practices come with many challenges, so we have several different products/treatments including in-furrow fertilizer, biologicals, in-furrow fungicide, and biological products for providing nitrogen to corn. We also have included herbicide demonstrations, showing how cover crops can increase water infiltration during pounding rains, as well as also reduce herbicide costs and improve weed control in soybeans.

All growing season long we’re providing opportunities to learn from our demonstrations in the Premier Agronomy Center. Follow @LathamSeeds on Facebook, Twitter, Instagram and YouTube. We share our weekly “Ask the Agronomist” videos, as well as season-specific information.

Summer Fertilizer Increases Alfalfa Winterhardiness

Core Catt, Forage Product Manager

With everything from groceries to gas on the rise, we understand the need to question whether expenses are necessary or justifiable. Below is information to support why fertilizing alfalfa in summer and applying fungicide to silage hybrids warrants your attention.

Fertilizing alfalfa in the summer helps fill the cellular gas tank of the plant’s crown, which helps increase its yield potential for the current growing season, as well as increases its potential for winterhardiness. All alfalfa benefits from in-season fertility, regardless of cutting schedule or strategy.

Summer seeding is fast approaching. July 20 through August 1 are key seeding dates for Latham Hi‑Tech Seeds’ northern territory, which includes North Dakota, as well as northern Minnesota and northern Wisconsin. August 1-15 is the range of recommended alfalfa seeding dates for southern Minnesota and southern Wisconsin while most alfalfa growers in Iowa typically seed in mid-August. Look at this graph.

Sourced from University of Wisconsin – Extension

Due to our late spring, many Midwest alfalfa growers have moved seeding alfalfa to this fall. The success of fall seeding depends on moisture. It’s important that alfalfa germinates quickly, develops a crown, and builds enough crown carbohydrates to overwinter.

Latham® AlfaShield^TMis a great seed treatment to help facilitate quick emergence. Think of AlfaShield as wrapping your alfalfa seed in a sponge. It helps protect the fragile germ of the seed. It also helps draw moisture to the seed, which is particularly important when seeding into moisture-stressed soils. Summers-seeded alfalfa is up against the time clock; approximately four to six weeks of significant growth needed to develop the crown before frost. The 2022 and 2023 Latham product guides include a dry matter (DM) ton advantage of AlfaShield compared to the old industry standard. AlfaShield has a bigger advantage in moisture-stressed soils.

Summer Considerations for Corn Silage

When I walk fields and test plots in the fall, I note a hybrid’s stay-green ability. I believe this observation relates to plant health. Healthy plants tend to have a lower probability of developing infection, which can create the environment for molds and mycotoxins to grow. Fungicide application promotes plant health and can boost yield and corn silage quality. Healthy, dark green, disease-free leaves are like solar panels capturing more sunlight for more photosynthesis. Healthy leaves also build more yield, as well as reduce chances for mold and mycotoxins to develop.

There are a variety of fungicides to select from, all of which inspire improved plant health. I have the most experience with BASF fungicide corn silage research relating to improved corn silage tonnage and forage quality. Several of the studies have resulted in two to three more tons of corn silage per acre plus the potential of reduced molds and mycotoxins is encouraging. With current commodity prices, that’s around an extra $140 to $210/acre in corn silage tonnage!

Investing fungicide is worth consideration for livestock producers, who raise their own forages. Molds and mycotoxins can be more challenging to quantify. When fed to livestock, however, they can severely impair animal performance. In severe instances, it can lead to mortality.

Feel free to contact your local Latham rep with any questions about summer fertilizing or fungicide application. You’re also welcome to email me at coreyc@lathamseeds.com. I’m always happy to visit with Midwest farmers who are interested in raising better meat, milk and eggs!

Alfalfa Threats

Corey Catt, Forage Product Manager

Like other crops, high-quality alfalfa is commanding a good price. Strong market prices can change the economic thresholds, making it easier to justify investing in pest control. Below are some charts to help guide you.

Many insects can damage alfalfa, so it’s important to build a plan that keeps alfalfa healthy. Insects can damage the plant so much that the plant can acquire a disease and die.

Each alfalfa plant is like a factory. Crop scouting, spraying and fertilizing is like providing critical maintenance to keep the factory operating efficiently, as well as to optimize yield and quality.

Controlling alfalfa insects generally involves two things: (1) spraying insecticide; and (2) cutting alfalfa early. Check out these two articles for more insight.

Try Something New!
Precision Agronomy Advisor, Phil Long

A common theme you will hear when listening to national corn/soybean contest winners is they always use a few acres to try something new. Latham’s Forage Products Manager, Corey Catt, has written numerous articles, encouraging growers to use a few acres to experiment on their own farms with products, seeding rates and management practices.

While third-party research plays an important role in helping us choose seed products, it’s also important to conduct your own on-farm research. Here are a few ideas to try this growing season. If you have acres that struggle with Sudden Death Syndrome, try treating a few soybean units with Latham® SoyShield^TM Plus with Saltro and run a side-by-side comparison. Another idea is to apply sulfur to soybeans and measure your results. Experiment on a few corn acres with Xyway® 3D in-furrow fungicide or try a phosphorus-enhancer, such as Encompass from TALC USA.

You could create quite a list of new products, different tillage/planting practices, in furrow fertilizers, or in-season practices that you could try to break your farm’s yield plateau. Here are some tips to make the most of your on-farm research efforts:
1. Use a decent farm, or part of a decent farm, to do your research. Use a farm that has soil types and drainage/topography characteristics that represent a lot of your acres. Don’t pick the less desirable ground in terms of fertility. If pH, phosphorus (P), and potassium (K), levels are wacky, you won’t learn much when trying a new in-furrow treatment, biological or fungicide. Basic needs must be taken care of before you can add more yield.
2. Keep it short and simple (K.I.S.S.). Weather and soil types cause enough variation in any research that you don’t need to add complexity. Try one thing at time, so you’re not adding multiple factors into the equation. For example, run a planter pass with Xyway mixed in your starter fertilizer and then shut it off the next pass. Do these two “treatments” at least three more times across your field to reduce the influence of soil types on your results.
3. Garbage in, garbage out. Make sure your monitors/globes/planting equipment have the latest update, so you can capture the data when it’s go time. Layout your research, so your combine can capture it. This is very important! For example, if you harvest with an 8-row head, change “treatments” on 20-foot increments.
Mapping what you do this spring will allow you to analyze it next fall. You will want to look at how that new product did in your heavy soils, lighter soils and whether it is worth expanding on more acres next year. Every year is different, so keep weather in mind as it is usually the #1 influencing factor. Start small to find out what works best on your farm. I am happy to help you figure out what new thing to try on a few acres. Give me a call and we can chat more about it at: 641-692-0370.

More Tonnage on Less Acres… What’s Your Blueprint?

Striving for tonnage and quality has never been more important than now with high cost of inputs and high commodity prices. More tonnage on less acres could mean more #2 yellow at a good price. Additionally, maximizing quality means more protein, more starch, more digestibility and greater feed efficiency.

What’s your blueprint to success for 2022? Here are a few things to consider:

Hybrid Selection for Corn Silage: Review of Latham’s 2021 Wisconsin corn silage trials results = WOW. This summary reveals the incredible tonnage some of our hybrids showed in the trials, blowing past the competition. We have many winning dual-purpose hybrids highlighted in our product guide, as well as our silage specific leafy hybrids. Check out these top-performing Latham® hybrid product numbers: 4937, 5245, 5742, 5965, 6285, 6477. Access to tonnage starts with hybrids that have historically had evidence of strong, known performance. Using trusted genetics has never been more important.

Seed Placement: Latham Seeds’ product guide provides specific placement details to help you achieve the best performance. Key in on the plant population for soil type, especially with the leafy hybrids. Leafy hybrids are massive plants, so they require a lot of in-row room to grow. To maximize leafy tonnage and starch, ensure proper seed depth. It’s important to promote the development of a superior nodal root system to hold up the large plant, as well as to bring in essential water and nutrients.

Nutrients: With a high premium on nitrogen, use in-season tissue and soil testing to determine whether the plant needs supplemental nutrition. Additionally, think about booking fungicides early to make sure you have them. High input investment coupled with high value commodity means many farmers will protect the plant with fungicides, so book early to ensure you have access to them! It seems a lot of helpful inputs are short supply, and fungicides like Headline AMP® have shown to produce 2 to 3 more tons/acre average. This is a very valuable consideration. When corn is $6/bushel, corn silage is about $60/ton. Adding 2 or 3 tons is about $120-$160/acre. A healthy corn plant adds more quality, as well as helps mitigate the expensive risk of mold and mycotoxins.

Know and Maximize Manure and Alfalfa Credits: The adage “think outside the box” recommends that we think freely and openly, so that we’re not bound by old, nonfunctional, or limiting rules or practices. While I believe there is a time and a place for this type of thinking, today I’m suggesting that we think “inside the box.” We can leverage what we already have.

What do you have on hand that can help reduce your expenses and minimize financial exposure?

Because the 2022 crop cycle is likely to set a record for the highest input investment crop, many farmers are scrutinizing every input. They’re leveraging what is on hand or readily available, so manure has become a highly sought-after resource. Manure also is proving to be effective. These manure credit charts give an idea of some “inside the box” considerations of nitrogen sources.

Additionally, corn planted on rotated alfalfa crop can yield as much as 20% more, especially in combination with manure. Applying manure requires some extra work and planning, here’s an online calculator to help you decide what manure is worth to your farm. Remember the intangibles. Manure provides the soil with needed nutrients, plus it unfolds a world of the living microbes.

Every growing season starts with a custom tailored blueprint. Consider how powerful genetics and some “inside the box” thinking can help you create more tons from less acres this season!
