Phytophthora Root and Stem Rot
Phytophthora root and stem rot is a significant disease affecting soybeans across Latham Country. It can kill and damage seedlings and plants from planting almost through harvest. This disease especially favors saturated conditions early in the growing season.

You’re most likely to find Phytophthora in the following places:
- Low, wet spots in a field
- Fields with high clay content
- Fields that have been in no-till for a few years
- Weedy areas that may be the result of stand reduction earlier in the season
Begin scouting as early as emergence where soils are saturated by heavy rains following planting. Where gaps in the row appear, carefully dig down to the seed zone. Infected seeds may rot before germination. Others may germinate but fail to make it to the surface.

In other instances, soybean plants may emerge from the soil and then die. These dying or dead plants often show a “pinching” of the stem just at or slightly below the soil line. This symptom is commonly referred to as damping-off.

If damping-off is a problem in the spring, watch for Phytophthora infection following rainy periods later in the season. The stem rot phase is easily recognizable by the presence of a distinct chocolate-brown lesion moving up the stem from the soil line. Initially, the upper stem of the plant may remain green. The plant will eventually wilt, turn yellow, and then die with leaves remaining attached.

The root rot phase of Phytophthora is not as readily recognized as the stem rot phase. Infected plants can be stunted and less vigorous, although this is hard to spot unless the infected plants are near a healthy comparison. A close inspection of the root system will reveal a significant reduction in the number of secondary roots and fine root hairs that help the plant take up moisture and nutrients. Plants with the root rot phase may mature a week or two earlier than healthy plants in the field.

Management

Many soybean varieties have resistance genes. The most common group of genes are known as Rps genes (“Resistant to Phytophthora sojae”). Varieties with “stacked” genes can show significantly higher resistance to Phytophthora. Specific information on PRR genes for each of Latham® soybean varieties is included in our 2023 Seed Guide.

Using Latham’s SoyShield® and SoyShield Plus seed treatments is a proven, effective way to protect against early-season diseases like Phytophthora. Using our seed treatment gives you the confidence and flexibility for a strong start to the growing season.

Mitigate Weather Risks with Best Management Practices
Weather concerns are top of mind as farmers across Latham Country look ahead to spring 2023 planting. Customers frequently ask us how to mitigate risk from the 2022 wet planting season.

While we want to maximize the yield potential of early planting, 2022 data shows us that delayed planting can result in very good yields — and better yields than planting when conditions are unfit.

Consider these factors to successfully mitigate potential risks of delayed planting:
1. Minimize compaction during field preparation.
  - A uniform seed bed creates the best opportunity to plant your crop with precision.
  - Minimize passes in the spring while creating a uniform seed bed.
  - Be careful not to cause sidewall compaction of seed trench at planting.
2. Plant your corn crop with precision. We want all plants to emerge within 72 hours. This creates the best root system to maximize water use through the entire growing season.
  - Plant a consistent seed depth.
  - Check for consistent seed spacing.
  - Ensure great seed-to-soil contact.
  - Delay planting if cold temps or cold rain is forecasted within 72 hours after planting.
3. Promote a healthy root system with fertility. Good fertility programs maintain a healthy, strong root system to effectively use available water.
  - Starter fertilizer gets corn plants off to the best start possible.
  - Side-dress Nitrogen in a timely manner to nurse optimum plant health.
  - Maintain a good fertility balance, using soil testing as a guide.
We suggest staying with a hybrid selection plan that does not vary significantly from previous years. A couple management changes at planting time to get your crop off to a great start will result in more success than totally changing your hybrid selection.

Remember, most corn yield is created in July and August. Get your plants off to the best start, so they can take advantage of that part of the growing season. Don’t get discouraged if you encounter a bit of a delay. Stick to the hybrids in your original plan through the end of May.

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.

Monster Cookies for Spring Planting!

From the time he was able to follow in his father’s shadow, Troy Johnson of Odebolt in West Central Iowa, spent as much time farming as possible. He began farming full-time with his father, Reese, upon graduating from high school. Shortly thereafter, Troy had the opportunity to purchase his first 40 acres.

The Johnson Family

The Johnsons raise corn, soybeans and alfalfa. They started using cover crops in 2015 and have expanded their cover crop acres every year. Benefits include increasing organic matter, controlling erosion, as well as better weed control and water infiltration.

“I’ve been planting Latham® soybeans since the beginning and started planting Latham Hybrids when they came out in 2004,” says Troy, a fourth generation Iowa farmer. “I’ve planted other brands for neighbors, and it’s easy to see the difference in quality when you open a bag. Latham is known for its high-quality standards, and its reputation is well deserved.”

When the Johnson’s neighbor Russ Wilken retired as a Latham® dealer, he asked if Troy would be interested in the dealership.

“I was already planting Latham, so it was a no brainer,” says Troy. “I always enjoy trying new things, so I appreciate getting to learn about new Latham products early. I really appreciate having a team of professionals available whenever I call. Latham Seeds provides us with great customer service.”

Just as Troy’s farming enterprise has grown throughout the years, so has his family. He and his wife, Kathi, are the proud parents of three daughters. Jaci is a sophomore at Odebolt-Arthur-Battle Creek-Ida Grove (OABCIG). She enjoys singing, reading and babysitting. Jaci also is involved in FFA. Sophi is in eighth grade. She plays the saxophone and is a volleyball player. In addition, Sophi enjoys designing cards with calligraphy. Tori, sixth grade, plays the piano and trumpet. She also plays volleyball, basketball and softball.

“We have been blessed to raise our children on the family farm,” says Kathi. “There are many values and lessons the girls have learned that will benefit them in the future. Although farming has its ups and downs, we are grateful to God for the life He has allowed us to live.”

A Tradition of Hospitality

Evelyn Latham, wife of Latham Seeds’ founder Willard Latham, was known for her gracious hospitality. She was sure to invite family, friends, neighbors and customers to sit down at the table to enjoy a fresh cup of coffee with a plate full of homemade cookies. It’s no wonder she was named Master Farm Homemaker in 1962 by Wallaces Farmer!

Throughout the years, we have shared some of Evelyn’s favorite recipes with our dealers and their families. We were delighted when Kathi shared with us that Jaci’s Monster Cookies advanced from the county 4-H competition to the 2017 Iowa State Fair. We can only imagine how delighted Evelyn would have been, knowing Jaci was creating wonderful memories with her mother in their kitchen.

“It was an honor to have my cookies selected to go to state,” Jaci, who earned a blue ribbon at the Iowa State Fair with her Monster Cookies. “I was not expecting that because 2017 was my first year exhibiting 4-H projects at the fair.”

Today we’re once again sharing Evelyn’s Monster Cookie recipe with our readers. We hope you’re able to share a cup of coffee and a few heartwarming smiles with friends, families and neighbors as you enjoy a few homemade cookies. Perhaps you can enjoy a few cookies this planting season!
