“Early growing season” can be described as planting through the first week in June; however, in reality it has more to do with crop size or stage and degree days than an actual calendar date.

Insect injury can cause stand loss and loss of leaf tissue, both of which can contribute to yield loss. Because insects are small, mobile, and sometimes nocturnal feeders, it may be difficult to actually find the insect. Here are some tips:

• Insects feeding below-ground can cause thin or irregular stands and poor germination. It is important to dig up seeds or seedlings to determine if an insect pest is present. Some insects, such as cutworms, can clip plants at the soil surface
• Some insects may be nocturnal and burrow into the soil during the day, making it difficult to identify the insect. Leaf-feeding is more obvious, and sometimes the insect may be present.
• However, if you see shot-holing you may need to cut the plant open to determine what is feeding in the whorl.

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.

“We feel blessed to be the third generation of Lathams to own and manage our family-owned seed company with headquarters on our Century Farm in North Central Iowa,” says John Latham, president, Latham Hi‑Tech Seeds. “We know that keeping a farm in the family for generations is challenging. That’s one reason we’re proud to sell through a farmer-dealer network. We appreciate working with multi-generational farmers, who plant our seed across the Upper Midwest.”

Last night’s celebration allowed Latham Seeds to showcase the latest seed traits and technologies during the grand opening of the Latham Premier Agronomy Center. There are more than 20 demo plots located within the Premier Agronomy Center, and guests got to choose which four they wanted to attend.

One of the more popular presentations featured two new trait platforms that protect against corn rootworm (CRW) that many farms are experiencing this season. The first corn hybrid trait platform is SmartStax® PRO, which combines “BT” traits with RNA structure. When eaten by the pest, this package interferes with an “essential-to-life protein” in the insects RNA (thus RNAi) and leads to insect control. This non-BT-based development will help control CRW in a new way plus extend the usefulness of BT-based controls. You will see the SmartStax PRO Trait package in LH 5008 SS PRO and LH 5668 SS PRO hybrids.

The second trait platform to control CRW is Duracade Viptera. This package combines BT traits with another BT rootworm trait that attaches uniquely to the insect’s gut when it’s eaten. It also provides above-ground protection from the Viptera trait. You will see the Agrisure Duracade Viptera trait package in LH 5209 DV hybrid. Latham® hybrids with Duracade Viptera and SmartStax PRO traits provide multiple modes of insect control for both above and below ground.

Another popular tour stop at the Premier Agronomy Center Grand Opening was the root and soil pit. While you can learn a lot from a root dig, you can learn even more when you dig deeper! Corn roots, night crawlers, compaction layers, earthworm channels and even water during a drought can be seen at the three to five-foot depth. Soil that is healthy deep down holds more water, has less run-off and supports plants during challenging weather. Healthy soil is also filled with microbes and worms.

Latham’s Agronomy Center field day went from 4 to 8 p.m. Following the field presentations, guests enjoyed Wholly Smoke BBQ, birthday cake and soft serve ice cream cones plus a live performance by Neil Hewitt.

Wholly Smoke BBQ from Dow, Iowa, had delicious smoked meats along with mac ‘n cheese. Such divine food reminded me of my favorite mac ‘n cheese recipe. Check it out below (courtesy of Cristen Clark, Food & Swine and Iowa Food and Family Project.)

If you’d like to schedule your own tour of the Premier Agronomy Center, contact your local Latham Seeds rep or call our office at 877-GO-LATHAM (877-465-2842). All growing season long, Latham Seeds provides opportunities to learn from demonstrations in the Premier Agronomy Center. Follow @LathamSeeds on Facebook, Twitter, Instagram and YouTube – and watch Latham’s weekly “Ask the Agronomist” videos.

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.

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.

Immediately after harvest is the best time to take soil samples for SCN. Several universities have programs that offer free soil samples to evaluate SCN, so check with your local Extension office to see if you qualify.

Think SCN isn’t a problem in your fields? Think again! Dry soil conditions, especially early in the growing season, can greatly increase the effects of SCN infestations. I received numerous calls in June and July about yellow, stunted soybeans. Most farmers suspected Iron Deficiency Chlorosis. Upon further inspection, SCN was almost always present and in larger numbers than previously observed. When I asked whether these farmers had taken a recent soil sample for SCN, most had not. They admit to mostly relying on SCN-resistant varieties to control or minimize the losses from this pest.

We have known for years that PI 88788 is gradually losing its efficacy against the pest, and more than 95% of SCN-resistant soybeans in America have PI 88788 as the source of gene resistance.  Since 1997, a team of researchers at Iowa State University led by Dr. Greg Tylka has conducted annual in-field trials with hundreds of SCN-resistant varieties. They measure agronomic performance and SCN population densities from planting until after harvest.

Scientists have determined that to be effective, SCN-resistant varieties must maintain less than a 10% reproduction rate of SCN during the growing season.  Since 2004, Dr. Tylka and his team have noticed that the average of all PI 88788 varieties in their trials have gradually exceeded that threshold. They have also noted that the average yield of those varieties has decreased as the SCN reproduction has increased. For more information on these studies, visit www.isuscntrials.info. Other land-grant university researchers have reported similar findings.

To effectively manage SCN in the future, soybean breeders are focusing on other sources of gene resistance. Your Latham Soybean Product Team is continually evaluating and searching for opportunities to bring new, better resistant varieties to our lineup. We also are evaluating several seed treatments for battling this pest. Saltro®, our seed treatment product for SDS protection, is also noted to have activity against SCN.  More information from our Latham Elite trials will be available post-harvest.

“TAKE THE TEST.  BEAT THE PEST.” is a slogan/campaign by The SCN Coalition and funded by the Soybean Checkoff and is designed specifically to promote awareness of SCN. These microscopic roundworms, which infect the roots of soybeans and other plants, can be present in a field for years before above-ground symptoms are visible. We encourage you to take the test this season, so you can plan accordingly for the future.
