XtendFlex soybeans, which were approved for global sale in September 2020, will be an important tool to manage resistant weeds. The combination of tolerance to dicamba (XtendiMax®, Engenia® and Tavium®), glyphosate (Roundup®) and glufosinate (Liberty®) herbicides offers a unique triple option of choices to control a wide range of grasses and broadleaf weeds in soybean fields.
Farmers who have used Roundup Ready 2 Xtend® soybeans are generally happy with their yields but desire better weed control options. Most farmers with whom I’ve visited believe they must wait as long as possible to apply the post-emergence dicamba products with the Xtend system. This application was later than ideal, resulting in weed escapes and even off-target movement of the dicamba herbicide to neighboring soybean fields that weren’t tolerant to that herbicide.
Using the XtendFlex system will allow farmers to apply dicamba herbicide earlier. They can spray either pre-emergence or early post-emergence when weeds are at labeled heights and are most sensitive to the herbicide. This should also greatly reduce the likelihood of off-target movement of dicamba to nearby sensitive crops.
Another benefit of the XtendFlex system is that farmers can apply Liberty herbicides up to the R2 stage of growth if there are any weed escapes. It is still highly recommended that weed management programs start with a pre-plant or early pre-emergence residual herbicide like Warrant®, Authority® or Sonic®. Regardless of which herbicide you use, please read and follow all label recommendations.
At press time, Latham Hi‑Tech Seeds will have seven XtendFlex soybeans available for spring 2021 planting:

Variable rate (VR) seeding in corn has been a frequent topic of conversation for years, but now that conversation is shifting to VR seeding soybeans. Before planting VR seeding soybeans, we must change the way we think.
When your yield potential goes up in a corn field, we increase population. When corn yield potential goes down, we decrease population. Makes sense, right? It’s the opposite for soybeans. When yield potential increases, lower your planting rate in a soybean field. When your yield potential decreases, increase the planting rate. Our trials to date have shown the most return on investment in lower-yielding environments where population was decreased.
Why invest more in a geography where yield potential is less for soybeans? There’s good reason! Percent germination in soybeans is one big reason.
When you plant tougher areas in the field, you’re not going to achieve 100% of your germination rate. Now think of your high yielding areas in your field… There is a much greater chance you will achieve close to 100% germination there. High-yielding areas typically have better soils and drainage, so it makes sense to plant more seed in low-yielding areas to increase the germination rate.
We enjoy sitting down with farmers and talking about whether VR planting is right for them. Our Data Forward™ team is here to help you get comfortable with implementation. Phil Long and I love to do On-Farm Trials in your own fields, so this could be a good starting place for farmers wanting to experiment with lower seeding rates. We can experiment on a smaller scale while placing learning blocks throughout the field. Using learning blocks and on-farm research allows us to compare different zones of a farmer’s field and to also compare to previous years.
Imagine the savings if we can drop soybean planting populations by even 20,000! The savings from reducing planting rates from 160,000 to 140,000 can then be invested into seed treatment or something else that protects yield and helps you achieve optimal germination. This allows farmers to continue to achieve higher yields while lowering planting populations.

Recently, Iowa State University Extension Entomologist Dr. Erin Hodgson delivered a presentation about the spread in 2020 of Soybean Gall Midge (SGM) to 19 more counties across five Midwestern states.
To recap, SGM was identified in 2011 in soybean fields in eastern Nebraska. Then in 2015 and 2016, it was discovered in South Dakota and Iowa, respectively. Widespread damage from SGM wasn’t noted until 2018, and also that year SGM was found in Minnesota. In 2019, SGM was found in Missouri. The scientific name of Soybean Gall Midge is Resseliella maxima.
Scouting for this pest can be very difficult as it is only about 1/10 of an inch long. Focus on the edges of soybean fields, beginning in those areas where you may have seen SGM damage the previous year. Look in your earliest planted soybean fields that are at the V3 stage or later for wilted plants that at first glance look like a disease problem. Then carefully check the base of the plant, giving a slight push to the plant base to see if it will snap off. If it does, split the base of the plant with a knife and look for the orange or white larvae. If you find Soybean Gall Midge, please report this to your local Extension Agronomist. Extension personnel are very interested in tracking the spread of this significant new pest.
Because farmers in Nebraska, South Dakota, Iowa, Missouri and Minnesota have been sharing their findings of SGM, Dr. Hodgson said she and her colleagues are making observations on the insect’s life cycle. Eggs are laid in soybean fields at from 2 to 4 inches deep. These eggs overwinter and emerge as adults the following year, flying into nearby soybean fields that are at that V3 stage or later where they will mate and lay eggs in soybean plants that have a wound or opening. These eggs hatch inside the plant with a total of three instars that will develop and feed on the inside of the plant. The third instar will be the largest and will usually be orange in color. These will eventually drop off the plant and burrow into the soil to later hatch and produce adults. This entire life cycle can take just 28 to 32 days.
Managing Soybean Gall Midge has proven to be very difficult as the larva are well protected by the plant and the presence of adults is extremely widespread through out the growing season. One researcher in Nebraska noted that adults could be found anytime between six and eight weeks in fields. While insecticides will easily control SGM adults, the timing of application over that period would be costly and tedious.
If you farm in the Missouri River area, please watch closely for Soybean Gall Midge and report your findings to your local Extension personnel. I would also appreciate a “heads up,” so I can make some observations of my own.
It was a beautiful, extended fall season, giving us ample time to finish tillage, fertilizer applications, tilling and other field work. Our machinery was strategically tucked away in the shed before the snow fell. Speaking of strategic placement…
Is your planter all the way in the back of the shed because you aren’t planning to touch it until March? Now is actually a good time to start thinking about your planter. New technology allows us to make our existing planter as good as – if not better than – the brand new planter on the lot at the implement dealership. One perk of working with us at Latham Hi‑Tech Seeds is using our Data ForwardSM services to help you make some unbiased decisions. Perhaps you weren’t happy with the way your corn was spaced in 2020 or maybe you noticed uneven emergence last spring. We can help you determine why this happened and fix these issues before going into 2021 planting season.
If you attended a plot tour last summer or listened online to our Corn Product Manager Lyle Marcus, you know he emphasized the importance of planting depth. It can be difficult to stay consistent across the field; controlling planter speed is one of the simplest ways to achieve optimum seed placement. We can review planter speed. We also can explore technology options for your planter, so you can monitor and control variabilities throughout a field.
Another factor to consider is planting depth. Oftentimes, we say 2.75 inches is a safe planting depth to allow adequate moisture and growing degree units (GDUs) to attain even emergence.
There is a lot of talk around two-inch planting depths. This could be optimal if there is adequate moisture. Planting at 2 inches with adequate moisture can get you better emergence due to having faster GDU adaptation. This also means that it could come out of the ground better in crusting conditions, but keep in mind that the key to shallower planting is moisture. It’s risky to rely on moisture being available at that shallower depth.
We spend a lot of time helping our Data Forward clients improve efficiency. While this can encompass many things, we focus on your planter, seed and equipment. We believe one of the most important assets to a farmer’s operation is the planter. If the planter is not equipped to place that seed where it is going to thrive, then other investments throughout the year are not going to be as valuable either.
One of our biggest challenges is helping clients achieve uniform, speedy emergence. If one plant emerges 24 to 48 hours after its neighbor, that plant will compete for the sunlight that its neighbor is already harvesting. The plant starving for sunlight will be a runt for the rest of the growing season.
Keep these four things in mind when trying to keep even heat and moisture to achieve even emergence:
