One of the things I like most about spring is you get to enjoy all four seasons in just a few days. In mid-April, we had snow flurries with an overnight low of 16 on a Sunday. A warm wind brought temperatures into the 70s by mid-week, and that weekend rain fell. That’s why I always tell people to plant by the conditions, not the date on the calendar!
Soil conditions are far more important than planting date. Rather than mudding in your seed to say that it was planted early, you’ll have a better chance of achieving maximum yield by planting into properly tilled soil. Working soils that are too wet leads to yield loss and more problems during the growing season from soil compaction. Restricted root development, nutrient deficiency and reduced infiltration rate are among the top 10 reasons to avoid soil compaction.
Adapted full-season corn hybrids can compensate somewhat for later plantings. As planting is delayed, hybrids shorten the time between planting and silking. Research shows that development and final yield of these hybrids will not be largely affected unless frost occurs especially early in the fall. That’s why we recommend waiting until May 15 in North Dakota and May 25 in Iowa before switching to an earlier maturing corn hybrid or switching to soybeans.
Patience is also key when planting soybeans. Planting into a field that is too wet will reduce emergence and plant population, which most often leads to reduced yield. Another cause of reduced yield is weed pressure. Make sure the sprayer is right behind the planters. Otherwise, soybeans might poke through the ground before your pre-emerge was applied.
We get one chance every spring to create the best seedbed possible for planting, so let’s take advantage of it! This may require a different piece of tillage equipment than originally planned, but taking the time to make the equipment switch will pay big dividends by resulting in better seed-to-soil contact that enhances germination and early growth.
Welcome back to week 5 of our Ask the Agronomist Podcast! Today, Phil explains the difference between abiotic and biotic issues in the field throughout Latham Country.
Cool, wet weather has slowed root development and some plants are showing a yellowing or purplish leaf color. Warm weather should enhance development of the roots. Normally, there is no yield reduction from plant discoloration at this time in the growing season unless it’s fertility driven by low nutrient levels.

We have cold saturated soils in Southeast South Dakota on the 23rd of May. Most corn fields are up and can be rowed on a drive by. Unfortunately, when you stop and look closely it, there is a bit of a yellow tint to it. These crops need sunshine and warm temps.

Things have really changed in the last week. Many areas received decent levels rainfall, which halted planting. Areas in Central South Dakota are still very dry, and areas in East Central South Dakota are very wet as more than 3″ of rain fell. Cool, cloudy weather slowed growth as you can see slight yellowing in corn. Emergence looks very good and even in corn and many soybeans are starting to crack.

If we could get a string of sunny days, corn planting could wrap up in Wisconsin. Sunshine and warmer temperatures are also needed to push along crop development.
Latham® Hybrid LH 5099 SS was planted May 8 in Ripon, Wisconsin. This field shows uniform emergence and growth, but that’s not the case everywhere. Unfortunately, cooler temps are hampering growth across the region.
With the significant rainfall we have had, it is important that growers get out and walk fields as conditions allow.
Call your local Latham seed supplier or RSM at 1.877.GO.LATHAM if you would like a second opinion as to whether replant is needed. Additional tips are available online here.

Look at all the technology going into this plot! We planted a Latham soybean plot near Friend, Nebraska, with the following:
**Balance™ GT Soybeans are not currently for sale by Latham Hi‑Tech Seeds until Balance Bean herbicide (Isoxaflutole) receives full regulatory approval.
Last November the U.S. EPA approved the use of XtendiMax® with VaporGrip® technology on Roundup Ready 2 Xtend® soybeans. It didn’t take long for competitors and opponents of the Xtend technology to point out the limitations, but many of their talking points are now moot.
The U.S. EPA, as promised, has allowed a number of significant changes to the XtendiMax herbicide label. First and foremost, Roundup PowerMAX® and WeatherMAX® formulations have been added. In addition, 34 (and counting) other herbicides are approved for tank-mixing with XtendiMax! There are now more than 110 approved adjuvants that may be added, plus the number of approved nozzles had grown to 26 as of early April.
For farmers who intend to use XtendiMax herbicide, visit their website often to stay abreast of the latest developments.
A section under the TANK MIX tab titled “REQUIRED DRIFT REDUCING ADJUVANTS (DRA’s)” lists products that minimize particle drift if used in combination with certain herbicides and other adjuvants. Products needing DRA’s are clearly spelled out in the herbicide and adjuvant sections.
Another very critical section of the website is “APPLICATION REQUIREMENTS.” Here, farmers can learn what is needed to minimize drift, volatilization and off-target applications of this important herbicide technology.
I’m excited to see so many early-adopters planning to use both Roundup Ready 2 Xtend soybeans, and the subsequent use of the XtendiMax with VaporGrip technology herbicide to help control tough-to-kill weeds in 2017. At Latham Hi‑Tech Seeds, we believe this will be just one of the many new and exciting soybean technologies that farmers will need to combat resistant weeds in the future.
Control Planting Conditions to Maximize Yield Potential
The planters are ready to roll as this is coming to you! That’s why I’m reminding everyone how important the proper start to the season is.
If the planting season gets off to a bad start, it’s only going to get worse throughout the growing season. That’s why it’s so important to plant into fit soil conditions, at the proper depth and at a slow enough speed.
As a farmer, I understand the urgency to get seed in the ground. We’re so eager that sometimes we mud the crop into a less than desirable seed bed, and sometimes we plant at higher speeds to get more acres planted in a day. However, days on the calendar don’t make up for mistakes in the field. Keep in mind that haste makes waste.
A few years ago, I conducted speed and planter depth testing on our farm. I found that our John Deere 7000 planter was most accurate at 4.5 to 4.8 miles per hour (mph), and our yields were the best at a depth of 1.75 to 2 inches. I saw as much as a 10-bushel difference at higher planting speeds and a 20-bushel difference when seed was planted at 1.25 to 1.5 inches deep. Root systems were considerably smaller where the seed was planted shallower and at faster speeds.
Also remember to check depth and spacing each time you move to a different field to ensure depth and spacing works in that field’s soil type and texture. Wishing you all a safe and great planting season!
The time is here! #Plant17 has arrived, and farmers throughout the region are gearing up for the 2017 growing season. Pictures can often best portray what is happening in the world around us, so we have updated our weekly From the Field crop reports! We will be sharing #crop17 highlights throughout our marketing territory, with a photo or two to accompany it.

Areas of the state were affected by winterkill on their alfalfa acres. Pictured here is a good stand of alfalfa in southern Wisconsin. It’s estimated that 75,000 to 100,000 acres of alfalfa in Wisconsin is suffering from some sort of winter damage.
As farmers wait for fields to dry out, there are still many farms that need to haul manure before planting can begin. A farmer is loaded up with turkey manure headed to the field, attempting to beat the rain.
A semi backs up to the seed shed of a dealer in Wisconsin. As the last bit of corn arrives, dealers are making sure to deliver seed to the growers before they hit the fields.
Seed sits in the shop awaiting dry weather to get planted. Most of the state has been blanketed with rain over the past two weeks, and more rain on the way Wednesday afternoon. Much of the state is waiting for the ground to dry out before working up any ground. Depending on how much rain is received Wednesday evening, I expect tillage equipment and planters to be rolling this weekend.

Quick Steps to Slow Spread of Soybean Aphid Resistance
The number one soybean insect pest is growing across the Upper Midwest. Recent reports indicate some aphid populations are developing resistance to insecticides, especially pyrethroid products.
While we may not be able to stop the spread of this resistance, we can certainly slow it down by using these best management practices:
Avoid spraying any insecticide if the economic threshold has not been reached. The accepted economic threshold is 250 aphids per plant in 80% of the field as long as the aphid population is increasing. This should not be confused with the injury threshold, which ranges from 600 to 700 aphids per plant. The economic threshold is designed to give farmers time to apply insecticide before the field reaches the injury threshold.
Use insecticides with different modes of action just like we use herbicides with different modes of action to help control resistant weeds. Some common examples of pyrethroid products include Warrior®, Mustang®, Asana®, Baythroid® and Pounce®, as well as a host of generic products. Lorsban® is an example of an organophosphate insecticide that may be used for aphid control.
Avoid adding insecticide to herbicide application just as “insurance” or to save a trip across the field, as this can easily lead to resistance problems.
When applying insecticides, good coverage is essential. Higher spray volumes and pressure help to move the product down into the soybean canopy.
As with many potential threats, scouting early and often is crucial to overall success!Soybean aphids can greatly increase in numbers if the weather is cooler than normal and if natural predators are not present.
First identified in Wisconsin during the summer of 2000, soybean aphids are found in 21 states and three Canadian provinces. Besides the damage they do by sucking sap from plants, aphids also are vectors of several viruses that attack soybeans.
Scouting for aphids is key for maintaining the health of your soybean crop now… and in the future. Do what you can now to keep numbers down and to avoid insecticide resistance from building.
There are lots of questions with any new products, and that’s also the case with Xtend soybeans and the new herbicide XtendiMax™ with VaporGrip™ technology. Below are answers to frequently asked questions:
Q. Do Xtend soybeans yield as well as other soybeans?
A. The short answer is yes. Latham’s Xtend soybeans excelled in the 2016 F.I.R.S.T. Trials. Like any soybean variety, optimal yield is achieved by placing them in the correct environment.
Q. Does VaporGrip control drift?
A. VaporGrip does NOT control drift, but it does significantly reduces the potential of volatility.
Q. How can I control drift?
A. Here’s a summary of required application requirements:
Use nozzles and operating pressure listed on the herbicide product label to minimize driftable fines. These nozzles make bigger droplets that, when used with lower pressure and a minimum of 10 gallons of spray solution per acre, help minimize drift.
Use at the application rate of 22 fluid ounces per acre for any single, in-crop application.
Do not exceed a boom height of 24 inches above the target pest or soybean canopy.
Apply when wind speed is between 3-10 mph, and avoid application if there is no breeze at all.
Do not exceed 15 mph ground speed.
Do not apply when wind is blowing toward adjacent susceptible crops.
Q. Do I have to put in a buffer strip?
A. The label requires a buffer to protect sensitive areas. Read and follow the label instructions.
Q. Can I apply Ammonium Sulfate (AMS) with XtendiMax with VaporGrip?
A. Ammonium Sulfate and ammonium-based additives are prohibited in applications that include XtendiMax with VaporGrip Technology.
Q. Can I tank mix any Roundup with XtendiMax herbicide?
A. To find a list of approved products for tank mixing, click here. Before application, farmers and applicators should visit http://www.roundupreadyxtend.com/ to see if any new products have been approved for tank mixing.
Q. Am I required to use a residual herbicide with XtendiMax with VaporGrip?
A. You are not required to do so, but using a residual pre- and post-emergence strategy as outlined in the Roundup Ready Xtend Crop System for in-crop use will give better weed control and can net you $14/acre cash back.
Q. Do I get any residual activity with XtendiMax Herbicide with Vapor Grip?
A. You can get up to 14 days of soil activity from Dicamba on certain small-seeded broadleaf weeds to help other residual herbicides control weeds.
Q. Do I have to spray XtendiMax Herbicide on Xtend soybeans.
A. No, you can spray Xtend soybeans with any herbicide approved for Roundup Ready soybeans.

Balance™ GT Soybeans: One Step Closer to Commercialization
Visitors to Latham headquarters last fall for our field day saw replicated tests of Balance GT along with EnlistTM, Roundup Ready 2 Xtend® and LibertyLink® soybeans. Plots conducted by Latham’s Research Team show there are good genetics to go with the Balance GT technology, so we’re eager for full approval to make them available.
February and March are key months for Latham’s product team as we focus on choosing next year’s product lineup. What we grow in 2017 becomes the seed we offer for 2018, so you might say our 2018 guide “hangs in the balance.”
Last month, Balance™ GT soybeans received import approval from China. Balance™ GT has already received approval from these critical countries: Argentina, Brazil, Canada and the European Union. However, Balance® Bean herbicide is pending registration.
Bayer has announced it won’t release the technology until the chemical is fully approved by the U.S. Environmental Protection Agency (EPA). Balance GT soybeans may be sprayed with glyphosate and with Balance Bean herbicide, which contains the same active ingredient as Balance herbicide for corn. Although the first generation of Balance GT products won’t have resistance to Liberty herbicide, Bayer plans to add Liberty resistance in the near future.
Balance™ GT and Monsanto’s Xtend™ soybeans have both been approved in the past year, and we’re hopeful that Dow’s Enlist™ soybeans will be approved in 2017. We’re eager for this approval for two reasons:
Farmers need new tools to win the fight against weed resistance.
Increased competition helps keep seed prices down. With the Bayer/Monsanto merger pending; all of these technologies would be controlled by one company: RR1, RR2, RR2 Xtend, Liberty and Balance GT. There’s a good chance one of more of these technologies will be sold for the Justice Department to approve the merger. I believe it’s in farmers’ best interest for these technologies to be owned by competing companies.
One benefit of our family-owned seed business is that we can access the industry’s latest and greatest technologies, regardless of which trait providers own them! That means Latham dealers can sell seed that best fits a customer’s situation.
As well, stay tuned for updates on new approvals. You can be sure we will offer new products as soon as they become commercially available!
