A couple bad storms blew through in the southwest part of my territory. Tornadoes touched down with the battered farm pictures to prove it. It’s really a shame as the corn silage corn in that area looked fantastic because it had received above-normal precipitation. Lots of tassels have started shooting out of corn in the past four to five days. It’s amazing how the development of corn and soybeans caught up with the hotter weather. The good news is it looks like there’s another week of ideal temperatures on the horizon.
Winter wheat harvest just started last weekend, and I expect to see many combines in the fields this week.

My grandson and I inspected a field of Latham LH 4940 CNV/LFY. Notice the big, wide leaves and the healthy plant. It still has a lot of growing to do before harvest, but you can tell by Carson’s smile that there will be plenty of tons of high quality silage this fall. Ask your Latham® dealer about all the great forage choices that Latham Seeds has to offer.

Corn is just starting to show tassels this week. We have had less moisture this past week, so yellowed corn is starting to root down some. Soybeans are putting on flowers and vegetation. We need continued warm weather for corn to reach maturity.

Mother Nature has once again proven that she is in charge. Corn fields across Southeast South Dakota were looking good, and the first planted fields were beginning to tassel. Then in rolled a severe thunderstorm on Saturday morning that caused damage across a large region of Eastern SD. While some areas had little to no damage, other areas were hit hard. In addition to many down power lines, trees were uprooted. Imagine what happened to the corn in a rapid growth stage! Pictures here is a field that goose-necked in the storm.

Tassels are beginning to shed on the early-planted acres. While walking fields this past week, I saw Grey Leaf Spot developing on the corn leaves.
Soybeans are beginning to close rows, and insects are becoming a concern. We haven’t seen aphids, but we are seeing a decent amount of Japanese Beetle pressure.
To maximize your crop’s potential, actively walk your fields and address any concerns. If you’re looking for a second opinion, I’m just a phone call away.

Here’s a great looking field of Latham’s LH 5200 conventional corn in Fillmore County, Minnesota, after a tough week of weather. Rainfall ranged from 4 to 6 six inches this week. These corn fields are starting to or have tasseled, and the weather has been favorable. We’ve experienced heat during the day with cooler nighttime temps. Soybean fields are starting to fill the rows and also are looking pretty good. Keep scouting your fields for any type of issues.
Eastern Iowa
Jerry Broders
The western part of my area got anywhere from 0.4 to 2 inches of rain this last week during the hot spell. Farms east of Interstate 380 were not as fortunate. The rain moved around us, and we caught about a tenth of an inch on Thursday. Fortunately, we didn’t get any damaging winds either.
It’s very hard to tell what is happening in in an entire field without flying over them with an airplane or drone. One of our Latham® dealers sent up his drone last Friday to scout a field. You can see where there was wet spot in the field that was planted three days later than the surrounding corn. There is about a two-foot difference in plant height, and there is definitely a reduced stand in area of the field. Most growers experienced similar conditions due to conditions during spring planting.
I’m also getting reports of Japanese beetles showing up in high numbers in soybean fields. Proactively scout as insect pressure starts to build in the field.

The Cause & Effect of Greensnap
Greensnap can occur during two of the most rapid vegetative growth stages of corn from V5 to V8 and from V12 to R1. During a corn’s rapid growth stage, internodes elongate and become susceptible to breaking off. From V12 to R1, a corn plant can grow up to 4 inches per day!
When greensnap occurs, it happens at the primary ear node which is detrimental to corn yield in the fall. Aside from high winds, other factors can include planting conditions, farm management practices and genetics of the corn plant.
When corn plants are in their first stage of rapid growth from V5 to V8, post-emergence herbicide is often applied. Growth-regulator herbicides can play a negative role in the integrity of the plant structure for short time after application. This combined with rapid plant growth weakens plant structure leaving it susceptible to greensnap.
Here are three suggestions to manage for greensnap in future crop years:
- Choose hybrids that have strong plant characteristics. We suggest selecting hybrids with above average root strength, stalk strength and disease resistance.
- Take a second look at your herbicide management plan, specifically time of application or reduction of growth regulator herbicides.
- Set your corn crop up for success from the beginning of the season by planting into a favorable seed bed at the appropriate seed depth. Give the seed a chance to establish a strong nodal root system to help withstand harsh weather through the growing season.
If you have questions on selecting the right hybrid for your field, let us know. We can connect you with one of our product specialists to ensure the right seed is placed on the right acre. This is the first step you can do to protect your corn crop from greensnap.

We finally got the rain and heat needed to make the crop flourish in Northwest North Dakota. It’s turning out to be one heck of a year for alfalfa. I’m already seeing bigger than normal stacks in the yards, and it’s good to see! A lot of cow/calf operations were running on empty this spring.
Wheat is starting to turn and harvest could start less than two weeks. There will be some huge swings in yields, depending on seeding dates. Early crops could be under 30 bushels per acre (bu/A) while the later stuff looks like 80 bu/A or more. It’s crazy to think this two-week window could mean $250/acre this year.
Southeast North Dakota
Gary Geske
The end of spraying season is near, but it’s never too late to apply the correct herbicides to the correct fields. We have many choices for herbicide traits for both corn and soybeans, and even more herbicide choices that may be used separately or in combinations. It’s a bad day when you see all your hard work this spring wilting away with a wrong application, so make sure planting maps are double checked before herbicide applications. It’s also a great idea to make sure your field entrances are marked with trait flags.
Southeast South Dakota
Ramie Coughlin
This week we’re looking at plant health below the surface. As a soybean plant’s cotyledons begin to turn yellow, a drop off the roots take over as the primary food and water source. We rarely apply nitrogen to soybeans, but they actually have a high demand for it. Soybeans get nitrogen through root nodules like these pictures. The nodules are formed from micro rhizobia in the soils.
To make sure your plants are getting the nitrogen they need, dig up a few plants. Make sure you can see white ball-like growths on the roots. Some are large and some are small. We like to see 3 to 5 large ones or 7 to 10 small nodules. Also make sure they are healthy, working nodules. Split it in half and look for a steak pink color. If it is green inside, it’s no good. Brown inside means it has run its course and is done.
Some soils have abundant mircro rhizobia, while others are lacking and require an inoculant is applied to the seed. The inoculant is live rhizobia and must be applied within a certain window before planting. Talk to your Latham Seeds Dealer or RSM to learn about the inoculant we offer.
Northeast South Dakota
James Keltgen
Warm weather continues to move along crop development across Northeast South Dakota. Soybeans are blooming and are finally growing through the Iron Deficiency Chlorosis. Corn looks like it will pollinate within the next week to two weeks. We have finally been on the drier side with only a few tenths of rain this past week. Corn is stunted and yellowing in lower areas due to standing water.
LH 3937 VT2 PRO RIB is about 2 weeks behind but looking good!

Joe Salter
Temperatures have been very hot and humid for the past week helping crops have grown rapidly. Many farmers in my area could use a shot of rain.
Pictured above is LH 4242 VT2 PRO.
Although it is hard to see in the photo below, there is significant variability in this plot and it’s not just due to different hybrid numbers. There are about 14 hybrids in this Latham SuperStrip™ plot, which tests existing and experimental products. What I love about these plots, is good or bad, we get a first-hand look at some of the potential up and coming genetics in our lineup.
Southern Wisconsin
Greg Mair
As I look at the Latham® corn and soybean plots around my territory, I can honestly say that I can’t wait until harvest! Our SuperStrip™ plots test products that are in our current lineup, as well as experimental numbers. It will be exciting to see which technology will be chosen for our 2020 lineup. My early pick is L 2349 E3. This Enlist soybean variety appeared taller and healthier in all three of the plots I walked this week.
I never thought I would say it this year after the spring we had, but we could use a rain. In southern Wisconsin, one area hasn’t had measurable rain in 22 days. It might be the driest growing season there in four years. You can see the LH 5245 VT2 PRO is starting to curl up in the afternoon heat.

Here is our new Enlist soybean L 2193 E in Mower County. Weather has been very hot and humid with some moisture here and there. Fields have started to take shape now that they’ve had some sunshine. Farmers are still spraying to control weeds, especially water hemp. Corn fields are getting closer to tassel stage.

Jerry Broders
Corn continues to grow at a rapid rate and some soybean fields are starting to close their rows. Lack of rain over the last 10 days and temperatures pushing into the 90’s is starting to stress both crops.
Northwest Iowa
Darin Chapman
The corn in these photos was planted on what I would call the “good window” around May 7. With a heat index of 100 degrees the past week, corn has grown rapidly. Keep an eye on the root structure and watch for corn root worm pressure. I’ve spoke with several farmers who are applying an early dose of fungicide to their corn that has experienced a lot of stress such as hail, late planting, or replant.
The other photos show a glimpse of the on-farm hybrid placement research we are working on with Latham Hi‑Tech Seed’s Data Forward program. There isn’t a difference in leaf color in the photo quite yet, so you can’t physically see the different hybrids in each zone. This should start to change soon. We are excited to see the results this fall, so stay tuned!

Latham® LH 4240 conventional corn in Webster County looks good at full tassel.
Central Iowa
Bryan Rohe
Tassels have started to show up and will continue for weeks to come as planting dates were widespread this year. The tassel is the beginning of an important process that starts ear development, and protecting the plants during this time is vital. Stress during this point of plant development can slow down this process, reducing yields.
There are many diseases this year that could affect our crops, so I highly recommend applying fungicide to both corn and soybeans. Data shows fungicides pay by allowing the plant to stay healthy.
During the past three years, we have seen a yield increase of 9.8 bushels per acre on first year corn and 14.9 bushels per acre on corn-on-corn Fungicide actually allows the hybrid to dry down further and finish as designed.
The best time to spray fungicide on soybeans is R3 to R4. The average yield response to soybean fungicide during the last three years has been 3.9 bushels per acre.

Recent rains have been a godsend to the drought-stressed area of my region in North Dakota. The Minot area received more than 2 inches in the past 24 hours, I’ve heard reports of 4 to 6 inches north of there. The corn and soybeans have turned the corner and look great.
Areas in Central and Southeast ND have more moisture than needed. This morning I noticed extreme lodging in wheat and an alarming amount of soybeans under water. https://droughtmonitor.unl.edu/CurrentMap/StateDroughtMonitor.aspx?ND

The corn is growing so tall that I have to keep a close eye on my little crop scout. Latham® LH 3937 VT2 PRO RIB is really stretching out with warmer weather. This is a great time for tissue testing fields. If there is a nutrient deficiency, make sure applications are made before tasseling so the plants get the most benefit.
Southeast South Dakota
Ramie Coughlin
Well, we made it! Many corn fields throughout SESD made it to knee-high by the Fourth of July. Although the norm has changed and we are used to seeing corn shoulder-high by this time of year, it still feels good to meet the goal of an old wives’ tale. Recent temperatures have been good to us. Daytime temps in the upper 80s help us accrue much needed heat units. Warm daytime combined with overnight lows below 70 have been ideal for corn growing.
They say it takes water to make water, and boy do we have water! Over the holiday weekend, many areas got 4 inches of rain. These two photos were taken just two miles apart. We are once again beyond saturated. However, as you get closer to central SD, it’s beginning to to dry up like usual. Crops there only receive 1/4” this past weekend.
Also last weekend, while sitting outside enjoy the fireworks show, I noticed fireflies. When you start seeing fireflies, it’s time to watch for rootworm. With potentially poor root systems from wet spring weather, it’s important to be proactive. Start scouting for rootworms in your corn fields.
Northeast South Dakota
James Keltgen
Although it has been hot enough in Northeast South Dakota to push along crop development, it has also been wet. More than six inches of rain has fallen during the past month. Some areas south of Watertown received that much in a short time period, cashing Highway 81 to flood.
Corn leaves are turning yellow firing as they show signs of stress from saturation. Soybeans have been stunted, as well. We’re also seeing some cutworm damaged to corn and soybeans, so make sure you’re scouting your fields.

This field of Latham® LH 0995 E-3 in Wilkin County Minnesota looks very healthy as it enters the R-1 development stage. To keep fields clean and healthy, weeds must be controlled. I’m seeing a lot of Lambsquarter as pictured here, Pigweed and winter annuals. Effective weed control requires a combination of tactics including tillage, herbicides and seed selection. Latham Hi‑Tech Seeds offers farmers choices with a full lineup of Roundup, Liberty link, Extend, LLGT27 and E-3 products. We need to be good stewards of these new traits and rotate them to prevent weed resistance.

This will be a good test of two soybean technologies and their corresponding herbicides for weed control. Latham® Roundup Ready 2 Extend® soybeans were planted in rows on the left and Latham’s Enlist E3 soybeans were seeded on the right. There is a bit of a planting overlap, which I am sure get adjusted properly when the sprayer runs the proper line.
I’ve been hearing reports of great weed kill with both portfolios this year. It really helped that the Extend window was pushed back to the 10th this year.
Although crop development is behind schedule, they’re turning the corner. Dirty fields are getting cleaned up, and rows are starting to close as plants grow. Have a good 4th of July weekend everyone!

I have been walking Latham SuperStrip and MiniStrip research plots the past few days and am very impressed with the rapid growth. One hybrid that keeps standing out is LH 3695 VT2 PRO RIB, which is shown here on the right. Notice how healthy it is. It’s dark green in color with semi-upright leaves. It’s very evident why 3695 was a plot winner last year. I expect it to be a repeat winner in 2019.
Northeast South Dakota
James Keltgen
“Wet” is still the theme across Northeast South Dakota. Another 2 to 3 inches of rain fell this week in many areas. Wet soils are making it hard for farmers to get spraying done. Corn is yellowing due to nitrogen loss. Fortunately, the heat has really moved corn development along. Corn will be knee high by the 4th of July. Iron Deficiency Chlorosis (IDC) also is showing up in soybeans. Remember to choose Latham® IRONCLAD soybeans in affected areas for future plantings.
Southeast South Dakota

With all the turmoil 2019 has brought us, I can honestly say that we have some healthy-looking crops. Plants are small but healthy. Soybeans are at V2 stage, working on unrolling that second trifoliate. We should start seeing flowers on soybeans in the next week or two. They will continue to grow in height but will begin their flower process shortly after the Fourth of July. Remember soybeans mature on a calendar year.

Latham Hi‑Tech Seeds
Early Season Fungicides
This year we have seen slow early growth, reduced tillage, persistent rain and heavy storms. We have also seen an increase in corn-on-corn acres and other agronomic challenges. All these problems can add up to more inoculum in the field and poor overall health leaving plants more susceptible to infection. The early season diseases we think about with corn are typically Anthracnose and seedling diseases (V2-V8); however, Gray Leaf Spot, Northern Corn Leaf Blight, Goss’s Wilt, Southern Rust and Tar Spot can all show early foliar symptoms (V8-R4). Its important to note that bacterial diseases like Goss’s can’t be controlled with a fungicide.
There is very little economic support for early season fungicide application. Depending on the individual fungicide, you may see protection against disease for anywhere from 7 to 21 days. Be sure to check the label for specifics on how long they retain efficacy on the crop. If your focus is on Anthracnose, you may stave off the leaf blight phase of the disease, but this doesn’t mean that the stalk rot phase of the disease won’t infect the plant late season.
It’s also important to remember that coverage is critical with fungicides. This not only means good coverage during your spray operation with correction nozzles, pressure and volume, but it also means that if you spray early in the season, your corn will grow a new leaf approximately every 3-5 days with average GDUs. That new tissue is not protected because fungicides are not very mobile in the plant.
When to Spray?
The best bang for your buck is still going to be around VT to R2 time period because you will be able to suppress diseases that may be present on the leaves and protect them for a few weeks of any diseases trying to get into the plant. Corn is also done putting on new leaves at this point. Typically a 5-8 bu/A yield increase will pay for the investment depending on grain price and application costs. If you are facing heavy disease pressure, be sure to select the right fungicide for the diseases you have. Fungicides with dual modes of action in the Group 3 (Triazoles) and 11 (QoI) will provide suppression and some lasting protection. Look for the active ingredients that end in “ole” (Triozoles) and “in” (QoI).
If you’re facing the fungicide decision to protect valuable yield in a tough year scout your fields for disease. If you don’t see any issues now, then skip an early application and focus on tassel. Take a look at the susceptibility of that hybrid to the disease you are seeing and then evaluate the weather outlook and if you’re in a corn-on-corn or reduced tillage situation. Lastly, monitor fields closely that had Tar Spot last season
It has been an interesting year with all the weather components we have had to face. If you have any questions, don’t hesitate to call in to the Latham Office.

One of my favorite times of the year is upon us. One of the best smells in agriculture or in my opinion, anywhere. First cutting alfalfa!
Delays in cutting is literally like a road map. Virtually zero hay cut in the south and east part of my region and well over 50% in the north and the west. It follows the moisture and the planting delays.

Gary Geske
This photo shows LH 3937 VT2 PRO RIB in a Latham SuperStrip™ plot east of Enderlin, North Dakota. Strong emergence scores and good early growth despite these cooler temps are helping all the Latham hybrids this spring.
North Dakota Agricultural Weather Network (NDAWN) recording sites are tracking heat units for corn growth, and it’s no surprise that heat units are way behind this year. The location at Lisbon has registered only 529 growing degree units (GDUs) since May 1, which is only 60% of last year at this time. Hopefully, warmer overnight temps will help bring this year’s crop to maturity.
Northeast South Dakota
James Keltgen
The main crop planting in is finally over in Northeast North Dakota. Now farmers with prevent plant acres are rushing to plant forages with the earlier harvest date set by the USDA. Warmer weather is expected this week, and heat is needed to move maturity along as all crops are lacking GDUs (growing degree units). Some herbicide damage is evident in corn due to the lack of growth and slow metabolization of herbicides. Soybeans should be flowering but also have been slow to progress due to the cooler weather. Remember to check herbicide application dates as many need to be applied shortly due to date and growth stage restrictions.
Southeast South Dakota
Ramie Coughlin
Surprisingly, last weekend we welcomed rain. Some farmers needed surface rain to break crusts and help seedlings emerge. The week also came with cooler temperatures. The 10-day outlook should be favorable corn growing weather, so we hope to see great progress. Many corn fields are close to canopy while others have a ways to go. I expect to see cover crops going in as a great option for all the prevent plant acres. Seed supply is tight, so contact your Latham® Dealer ASAP to reserve seed.

Joe Salter
The Northern Wisconsin crop looks better every day. Warmer days with scattered rain are in the forecast. The crop is popping out of the ground and making great gains. Weed issues also surfaced last week as you can see in this field planted to Latham® LH 4452 RR. The biggest weed issue is giant ragweed. Giant ragweed, which grows taller than corn in search for sunlight, is considered one of the most competitive weeds in our agronomic crops. Giant Ragweed has also shown herbicide resistance. This field was sprayed one week ago, so it will get special attention over the next week to make sure this competitive weed does not survive.
Southern Wisconsin
Greg Mair
With excessive moisture falling across the region this spring, we’re seeing nutrient deficiencies and compaction in corn. Sulfur is not available on the lighter, sandy soils, causing light green variable stands across fields.
It’s important to walk fields this time of year to address issues before significant yield loss occurs. We’re spraying soybean stands in southern Wisconsin for Thistle Caterpillars.
North Central Iowa
Cory Greiman
This leaf discoloration appears to be from frost damage, but we haven’t had any sub-32 degree temperatures. It is a result from rapid temperature change. We’ve seen spring temps range from the low 90s to the mid-40’s with high humidity, giving corn the appearance of frost damage.

This field of late-planted soybeans near Oskaloosa could start flowering in two to three weeks.
