“Now, what problems are we having on offense?” - John Gigliardi head football coach at halftime with his team up 35-0

 

Despite any given situation, there is always room for improvement.  Sometimes the situation may look so bleak that improvement is the only option going forward (commodity markets in July of 2020).  However, there are situations where things are going well and most would just hope to maintain the momentum.  Usually, it takes a unique individual to take a good situation and continue to find ways to push forward to make it even better.

Coach Gigliardi (pronounced Gil-ardi) was one of those folks and a big reason why he is the winningest football coach in college history (486 career wins).  You most likely have never heard of the guy as he coached at the Div. III institution of St. John’s University in central Minnesota.  Regardless of his team’s position during a game, season, or off-season, John didn’t let-up on his focus to keep the program’s football team at a consistent high level as well as provide the student athlete a rewarding college experience. 

Many large farms have been highly successful over the past half-dozen seasons despite the depressed farm economy – they just have a knack at finding ways to succeed no matter the circumstances.  Now that the agriculture landscape is changing again, new challenges will arise and I’m sure many of you will continue to find ways to challenge your teams and maintain your status as top farm operations in the region.  Good luck!

Regional Weather

The above average conditions are forecasted to continue again for the week, and we’ll even have some mornings without freezing.  It’s starting to be very difficult to even find snow in the tree rows!  Our next chance of significant precipitation looks to be forming for the first part of next week. 

Well, I couldn’t even get out a soil temp chart for the region before a couple farm operations found a chance to sow a quarter or two of spring wheat.  It’s not very often we get the chance to place some seed in the ground before May (let alone before April), but taking a roll of the dice doesn’t intimidate too many large successful farm managers.



This soil temperature chart (oFahrenheit) comes from NDAWN at 9 am Monday, March 15th.  As you can see, most locations are bordering on the frost/freeze point in the top 1-2 foot of soil depth.  There is some slightly warmer soil much deeper.  Fargo, Logan Center, Carrington, Maddock, and Williston all have soil temperatures above 32.0F at all depths – some locations, like Logan Center, just barely make the cut.

I’ll count on your weather app for the best guidance through the 7-8 day forecast, but looking beyond that, I’ve found this site from National Oceanic Atmospheric Association (NOAA) to be fairly reliable for a general 8-14 day outlook (next week). 

https://www.cpc.ncep.noaa.gov/products/predictions/814day/index.php

For the fourth full week of March, the forecast is towards significantly warmer than average potential for temperatures.  Regarding the precipitation chances, they remain below average for central and western North Dakota, and above average for northwestern Minnesota.

The NOAA organization also provides three month outlooks.  If we would like to get a general forecast for the key months to start the upcoming growing season (May-June-July), it can be seen here:

https://www.cpc.ncep.noaa.gov.../long_range/seasonal.php?lead=3

This forecast currently predicts significantly above average chances on the temperature potential, along with equal chances for precipitation in northwestern Minnesota.  For most of North Dakota, the precipitation chances trend towards drier than average.  It continues to be a developing situation that points our thoughts and actions towards conserving soil moisture.


Pre-emerge Herbicide Concerns in a Dry Spring

I’ve fielded a few questions over the last couple weeks on pre-emerge herbicide use during a dry spring.  The farmer concerns are around the herbicide potentially volatilizing into the atmosphere or not providing much control if it has sit on the soil surface for numerous days to a couple weeks without a 0.5” to 1” rain for thorough incorporation.

Fortunately, most herbicides break-down by microbial activity and/or complex chemical reactions in moist soil (hydrolysis).  Therefore, these herbicides will remain stable on the soil surface in concentration for prolonged periods.  Yes, not all herbicides fall into this category and a couple do break down by sunlight and UV wavelengths. However, we typically apply these herbicides with immediate soil incorporation – Eptam® and Far-go® primarily come to mind.  The yellow herbicides of Sonalan®, Prowl®, and Treflan® also degrade by UV light and work best with soil incorporation.  Metolachlor (Dual®/EverpreX®) has recently been found to have some breakdown by sunlight as well – however, other similar herbicides in this class of chemistry are not affected.

Unfortunately, if conditions do remain dry and only minimal small rains of say 0.15” or less do occur, then usually the herbicide does not become fully activated.  However, the weeds have enough moisture to germinate and become established.  The good news is that unless the weeds get large (over ½” to ¾” tall) most good pre-herbicides will “reach-back” to provide control once that incorporating rain is received (Valor™, Zidua™, Sharpen, and sulfentrazone products).  Once the incorporating rain is received, a good activation period will ensue to prevent new weed seedlings from emerging.

https://www.ag.ndsu.edu/.../fate-of-soil-applied-herbicides-05-26-16

A 2016/’17 study by NDSU found that when incorporating rain was delayed 7 days after per-herbicide application, the pre-herbicide products of Fierce® (flumioxazin (Valor®) + pyroxasulfone (Zidua®)) and Spartan® (sulfrentrazone) maintained very strong weed kill performance.  Meanwhile, metribuzin (Sencor®) did degrade slightly in performance with a 7 day wait for incorporation.  Unfortunately, these were the only three herbicides tested in the trial.

Corn Herbicide Options from Corteva™

Having an early weed control mindset for our crops this season should help maintain a jump on the weeds and conserve moisture.  It seems like the weeds always seem tougher to kill post-emerge under dry conditions when they get some size.  In the corn, more and more operations are finding the early V-1 to V-3 crop growth stage is about perfect for applying a robust herbicide mix to control emerged weeds as well as adding some residual control.  For Corteva™ based options in our region, a couple ideas come to mind.

·       


  Keystone LA® NXT + WideMatch® – this herbicide mix is gaining popularity has it has minimal crop rotation restrictions.  Actechlor, atrazine, copyralid (Stinger®) and fluroxypyr (Starane®) are all in this mix.  If you add some glyphosate we’ll have at least a couple active ingredients targeting most weed species.  At an application rate for Keystone of 1.8 qts/ac, it equates to only 3/8 lb. of atrazine, providing adequate crop rotation flexibility.  Keystone label: https://...agrian-cg-fs1-production/pdfs/Keystone_LA_NXT1d_Label.pdf

·        


Resicore® - this product fits more of our corn-soybean-wheat farm operations, but is a robust pre-mix that does an outstanding job of  controlling all of our tough broadleaf weeds plus provide that critical residual control.  Resicore® contains acetochlor, mesiotrione, and copyralid.  Add some glyphosate and atrazine, and you have another great tank-mix combination of at least two to three active ingredients working together to control most weed species.  It’s the mesiotrione that gives us a crop rotation restriction of 18 months to sugarbeets, potatoes and dry edible beans.  Check the atrazine load as well.  Resicore® label: https://...agrian-cg-fs1-production/pdfs/Resicore1u_Label.pdf

·         Resolve Q® - If you are unwilling to apply HPPD inhibitors (like mesiotrione (Calisto®)) you most likely will struggle to control volunteer canola in your corn crop.  Therefore, Resolve Q® is a fantastic option to add to your tank-mix in the post-emerge application.  Resolve Q® has a 20” or seven collar crop growth stage application restriction, but works best on volunteer canola less than 4-5” in height.  Resolve Q is a pre-mix of rimsulfuron (Basis®) and thifensulfuron (a component of Affinity®).  https://...agrian-cg-fs1-production/pdfs/...Resolve_Q_Label.pdf



Corn Fertility Management

Even though you may be hitting strong yield levels in your corn production, is there room for improvement?  Earlier this winter, I had the pleasure of listening to one of our Pioneer managers down in the Texas panhandle (high dessert plains region) assisting his growers with top production practices.  If you’ve never experienced the area, they are significant into irrigated corn and alfalfa to support the large cattle feedlot operations in the region.  The elevation is 5-6000 feet in general with only about 10” of average annual precipitation.  Soils are fairly sandy with very low water holding capacity, thus the need to irrigate over 20” per summer for 98-107 RM corn hybrids.

Anyway, a few things from his presentation really stuck with me and some ideas we may look to implement in the Northern Plains.  First, was the emphasis on getting away from broadcast spreading dry fertilizer.  With our region’s high clay content and high pH soils (above 7.8 in many areas), having our fertilizer become plant available can be a challenge.  The primary method to over-come the obstacle is the banding of fertilizer in the fall or pre-plant in the spring.  This doesn’t have to be too complex with special equipment – no reason the air-seeder couldn’t perform some fertilizer only applications in the autumn.

If we evaluate an acre-furrow-slice (AFS) – that is a slice of soil covering one acre to a depth of 6” – it will generally weigh around 2.0 mil pounds.  A broadcast application of a dry blend (N-P-K-S-Zn) at 400 lbs/ac which is incorporated to a depth of 3”, results somewhere in the realm of 100 to 200 ppm concentration of fertilizer in the top half of the AFS.  On the flip side, banding can create zones of fertilizer concentration significantly much larger and thus less available for soil tie-up, making more fertilizer obtainable for plant uptake.


Second, was to implement more than one pass of fertility application in the corn crop.  As you know, corn is a very full season crop with a large nitrogen demand.  However, what you may not realize is how late in the season the plant needs a good portion of that nitrogen.  It is estimated that today’s corn hybrids need about 40% of their nitrogen requirement after the tassel growth stage.  So, for the end of July through the month of August in a 180 bu/ac corn crop in our region, the crop will require about 65-75 lbs/ac nitrogen in that time span alone. 

Another benefit from an in-season application would be to gain on the nitrogen use efficiency.  Often, the combination of banding fertilizer applications – pre-plant along with starter fertilizer use and at least one application side-dress, the nitrogen efficiency can be improved to 0.8 to 0.9 lbs N/bu corn produced.  If only a pre-plant broadcast application is applied, the recommendation moves to 1.2 to 1.3 lbs N/bu of Yield Goal.  I know our soils can hold more moisture and thus more nitrogen than the dessert high plains region, but I would bet we could improve both yields and nitrogen use efficiency in our region if we invested in a method to apply nitrogen to our corn crop at least once during the season and in combination with banding other fertilizer applications.

With better late season fertility, most operations are also able to maintain better late season plant health and standability.  Many folks look for plant health benefits from late season fungicides/ insecticides, but we shouldn’t forget about the nutrition aspect as well.  My guess would be the fertilizer probably has more of an impact on the overall impact of corn yield production and standability for our region than mid-season pesticide application.  Typically, we have very low presence (most years) of late season disease and insect pressure.

At the end of the day, nitrogen is just one component of the season’s corn fertility needs.  Don’t forget about the other elements like sulfur – typical corn production in our area needs 12-20 lbs/ac sulfur.

 

Product Spotlight: Instinct® NXTGEN

To continue with the topic of fertilizer management, not all farm operations have the time, manpower, and/or capital to apply nitrogen in two or more different applications to the crop.  Therefore, maybe there is an alternative solution to where we can improve our efficiency with our nitrogen dollars and still obtain top production goals.

Optinyte™ technology (nitrapyrin) has been around since the 1960’s, and there is plenty of university data out there to support the product and confirm that it performs as stated.  However, there has always been issues around the formulation and mixing thoroughly with the nitrogen source for it to gain significant traction.  Many manufacturers have tried to take the off-patent product and bring it to market, but they have also experienced valid concerns with the products ability to mix.  Anyway, Corteva has a new formulation out with Instinct® NXTGEN to use with urea and the product has dramatically improved the flowability and mixing for fertilizer retailers as well as in on-farm application systems.


In corn, split applications of nitrogen most often reveal a positive response and are viewed as an “ideal” nitrogen management program as a corn producer can modify the plan as needed on the fly.  If the spring has been wet and thus the potential high for nitrogen leaching or denitrification, then we may want to add more nitrogen than originally planned.  Conversely, if a fairly dry spring and the outlook for below average yields, then we may adjust downward on the nitrogen rate. 

In more heavy clay loam soils, our nitrogen applications are more protected from leaching due to the clay slowing the water infiltration movement through the soil profile.  However, under very wet saturated conditions nitrogen loss occurs to denitrification.  Optinyte® technology keeps the nitrogen stable under both leaching and denitrification scenarios.

If you have history of detecting nitrogen deficiency late season in corn, or you find yourself significantly above 1.1 lb of nitrogen planned per bushel of crop production goal, then nitrogen inhibitors should be considered and tested on the farm.

https://...agrian-cg-fs1-production/pdfs/Instinct_II_Label1i.pdf

NDSU has a nice publication on the topic from 2017 with a comprehensive evaluation of current products on the market.  https://www.ag.ndsu.edu/publications/crops/nitrogen-extenders-and-additives-for-field-crops



Product Spotlight (2): P9193AM


The last product in our series of new Pioneer corn genetics for the spring in our region is P9193AM.  It’s another strong agronomic hybrid with above average trait characteristic scores for drought, stress emergence, brittle-snap, late season standability, and Goss’s Wilt.  It’s medium for plant height at 91 RM (relative maturity).  Yield potential is solid as our IMPACT data reveals a bit more horsepower than other industry hybrids in the 90 RM zone – including P9188AM.  If this P9193AM can demonstrate as much consistency as P9188AM, we’ll have another strong hybrid in the 90 RM segment.

For a quick review, Pioneer rates their products on a 1-9 scale with 9 being the best/strongest/tallest.  Average characteristic performance scores are typically 4’s and 5’s; below average is 3, and above average strength would rate 6 to 7.  It is fairly rare to see an advanced product with a trait score of 8, but it does happen.  Most all products that would rate below a 3 on any given single agronomic score would not make it through the process to become a commercially available product.

There are enough units of this hybrid to be included in Pioneer’s PKP strip trial plots for the upcoming season, plus have some additional supply for large side-x-side comparisons against competitive hybrids.  If you’d be interested in having a strip trial or comparison trail on your farm, please reach-out to myself and/or your local Pioneer agent and we’ll put a plan in place.

 

Random Agricultural Facts – Daylight Savings Time History

Most all states in the US implement Daylight Saving Time (DST), but can you name the two that don’t?   If Hawaii was the first state that came to mind that would be correct as they are our country’s southernmost state and therefore daily sunlight hours do not vary as much throughout the year compared to locations with more northern latitudes.  Arizona (most locations) would be the other state as they feel an energy savings is more consistent during the spring and summer months without the added extra hour of evening daylight.  The fact of cooler temps earlier in the evening and throughout a longer stretch of the nighttime sleep hours should justify the state legislature’s actions.

Most of the US territories also do not observe DST: Puerto Rico, Guam, American Samoa, US Virgin Islands, and the Northern Marina Islands – also due to their daylight hours being fairly consistent over the course of a 12-month period.  Any potential advantages of DST in these locations would be very minimal.  With today’s amenities imbedded in our culture, one would think DST’s impact in saving energy is fairly minimal.

Across the globe, DST is primarily implemented in North American and Europe.  It’s interesting to note that countries such as Iceland, Kazakhstan, Mongolia, and Russia no longer implement DST, despite their northern latitudinal location.

March 8, 2021 Edition

 



“Hey Marc… I’m currently working on a land deal.  I may need about 2,500 additional acres of Pioneer® soybean seed.  You still have some, right?”

“Oh yeah, we can get you some Pioneer® soybeans – no worries.”

“Noooo, I want the really good ones.  You know, that high yielding Pioneer® variety we had last year.”

“You worry about the land deal; I’ll ensure the seed supply.”


Well, it’s that time of year where a successful seed company is sold-out on a few products, but that is expected – I’m sure you currently have some empty grain storage bins in your business too!  It is also expected that a large successful seed company will have some quality genetics remaining for our customers who have found additional opportunities.  If you are tweaking your crop rotation plans now that crop insurance premiums are set, or have found some additional land to farm, top performing Pioneer genetics can still be acquired – it’s our job to be a reliable seed supplier and that is why you folks do business with a company like Pioneer® and Corteva®.

At the end of the day, the services our Pioneer® sales agency teams provide of seed treating, delivering seed, helping customers place a hybrid/variety by field plan together, scouting pests, monitoring genetics, etc. are the most important activities we conduct each year.  However, it’s nice to be able to provide some additional product during the winter and spring to further support our customers as needed.  Also, it’s great to get some positive feedback on our genetic performance.  Thanks for all the tremendous support this season and over the years.  We look to keep our activity and engagement level high going through the spring and summer.


Regional Weather

It should be another week of melting and thawing conditions as most days are forecasted for high temps in the 40’s and 50’s.  The snow pack is about gone and soil temps should begin to build soon as conditions thaw-out.  Unfortunately, there is not much chance of precipitation for the week, but most folks would appreciate some rain to help remove the frost.  I’ll include an NDAWN soil temp map next week.

I’ll count on your weather app for the best guidance through the 7-8 day forecast, but looking beyond that, I’ve found this site from National Oceanic Atmospheric Association (NOAA) to be fairly reliable for a general 8-14 day outlook (next week). 

https://www.cpc.ncep.noaa.gov/products/predictions/814day/index.php

For the third full week of March, the forecast is towards cooler than average potential for temperatures.  Regarding the precipitation chances, they remain below average for the region.

The NOAA organization also provides three month outlooks.  If we would like to get a general forecast for the key months of the upcoming growing season (Jun-Jul-Aug), it can be seen here:

https://www.cpc.ncep.noaa.gov/products/predictions/long_range/...lead=4

This forecast currently predicts above average chances on the temperature potential, along with equal chances for precipitation in our region.  Overall, that would typically be welcome news, but with our current dry conditions, we hope to see those equal chances trend towards more precipitation developing for the crops.



Corteva® to Discontinue Fexepan™ Herbicide

As Corteva® continues to strive towards fully supporting the Enlist™ or E-3 soybean weed control system for the future, it has decided to withdraw support for Fexepan™ (branded dicamba formulation for use in RR2Xtend® soybeans).  The Corteva sales team will continue to support Xtend® A-Series™ soybean genetics and full weed management programs which can entail other Corteva herbicides such as Sonic™, Afforia™, Durango™, Kyber™ and/or EverpreX™.

http://news.agropages.com/News/NewsDetail---38187.htm



Soybean Herbicide Options from Corteva™

Speaking of soybeans and herbicides, let’s review these Corteva™ options for spending some of those TruChoice® dollars.  Afforia® is our top pre-emerge product for the region due to its great rotation flexibility (10 months to sugarbeets; 6 months to potatoes with pre-plant tillage).

Afforia® is a premix of flumioxazin (Valor®), tribenuron (Express®), and thifensulfuron (Harmony®).  It’s strength for controlled weeds will be lambsquarter, pigweeds, dandelion, Canada thistle, and volunteer canola.  Afforia® will be weak on kochia and ragweed; if you can handle the changes in crop rotation restrictions, add some metribuzin (Sencor®).  Alternatively, the kochia and ragweed management plan can lean-on the dicamba or 2,4-D choline in the post-emerge application.  https://...DuPont_Afforia_Herbicide_Label2.pdf


Speaking of metribuzin, a new option from Corteva™ for a pre-emerge option in soybeans is Kyber™.  Obviously, Kyber™ will create some longer crop rotation intervals than Afforia® with the metribuzin in the jug, but it brings activity against kochia and common ragweed to the table.  Crop rotation restrictions will be 18 months to canola, potatoes, and sugarbeets.  Kyber™ is a pre-mix of flumioxazin (Valor), pyroxasulfone (Zidua®), and metribuzin (Sencor®) – with the Zidua® in the tank, it’ll be priced as a premium product, but well worth the dollars from a weed spectrum and weed control standpoint.  https://...production/pdfs/Kyber_Label1.pdf


Enlist One® and Enlist Duo® are Corteva’s™ two different 2,4-D choline formulations.  Enlist One® is pure 2,4-D choline product, while the Enlist Duo® brings glyphosate (Durango®) into the jug.  There has been some documented cases of additional broadleaf weed resistance to 2,4-D since the introduction of Enlist™ soybeans in southern states so the use of a pre-emerge product is highly recommended within the weed control system.  https://...Enlist_Duo1m_Label.pdf


EverpreX® is Corteva’s S-metolachlor product.  Metolachlor’s residual control is best on small seeded broadleaf weeds like pigweeds, lambsquarter, waterhemp, and nightshades along with grass weeds like foxtails and barnyardgrass.  EverpreX® can be utilized pre-emerge, but it’s primary fit would be used as a layby treatment in post-emerge mixes with the 2,4-D/dicamba for extended residual.  If you are looking for a product to help control late emerging waterhemp, metolachlor is your answer.  https://...DuPont_EverpreX_Label.pdf



Women’s History Month

March is Women’s History Month, and International Women’s Day is celebrated globally on March 8.  We all know the significance around the world that women play in agriculture.  It may be a surprising statistic, but it’s estimated that women represent 43% of the world’s food production workforce and more than 25% of its farming population.  Women play a crucial role in producing ag-commodities – many are highly involved in agriculture through various facets, and on the farm, many families view the husband and wife as equal contributors to the business’ overall success.

If your farm operation has women on the employee or management team, or women as an outside partner/influencer, please take advantage in the month of March to let them know how much they are appreciated.  It’s a great opportunities to reflect on the vital role women can and do play in agriculture.

China’s Domestic Soybean Futures Price Hits Record High

In China, it’s the Dalian Commodity Exchange in Shanghai as the primary board of trade for agriculture commodities.  It is forecasted that Chinese soybean crushers will have to slow-down operations soon as the soybean harvest in Brazil is delayed.  Supposedly, top grade soybean futures prices rose to 6,058 yuan/MT on March 1st.  With the yuan equal to 15.48 cents of the US dollar and 2200 lbs/MT, it would calculate to US$25.57 per 60 lb bu.

https://www.brecorder.com/news/40068937



Shipping Container Squeeze

China is rebounding from the pandemic in a quicker fashion than other nations at this time.  Their recovery has placed a significant pinch on a critical component to exports – shipping containers.  The squeeze is so significant that China is paying for freight to have the containers returned empty as other countries struggle with logistics in the turn-around time.

China’s large trade imbalance typically results in the volume to export three shipping containers full of goods for every one container imported.  It is estimated that approximately 60% of global goods are moved by shipping containers.

The current shortage of shipping containers is causing freight costs to increase dramatically as Chinese manufacturer’s raise their bids for shipping space.  Forty-foot container shipping cost is up 85% since June.  With international passenger airline flight volumes also greatly reduced due to the pandemic, airplane cargo volume capacity is below typical levels - also creating additional short-term demand for shipping containers.

Crop Insurance - 2021

Kent Thiesse from the MInnStar Bank had an excellent article on crop insurance options for the 2021 growing season.  Kent writes a great weekly column and I’d recommend sending him a simple e-mail and requesting access to his insights (if not already) (kent.thiesse@minnstarbank.com).

Here are some of Mr. Thiesse’s views on crop insurance selections this particular growing season:

·         Base price revenue protection and yield protection have been set for 2021 at $4.58/bu for corn, and $11.87/bu for soybeans.  These prices are the highest since 2013/’14

·         Fully evaluate the 80% or 85% coverage levels.  Yep, they cost more of a premium, but can guarantee profitable revenue (depending on APH yields)

·         “Supplemental Crop Option” (SCO) and “Enhanced Coverage Option” (ECO) are both available for 2021.  These are options to gain added coverage under either PLC or ARC-CO with significant portions of the premium subsidized

·         Other “buy-up” private policies along with SCO and ECO will combine to allow up to 95% coverage

·         “Optional” versus “enterprise” units.  Often, “enterprise units” get most of the play due to cheaper premiums, but there are instances when “optional units” does make sense despite the added costs.  Typically, this would be in situations where farm units are more spread out geographically and yields more variable across the farm

·         Lastly, evaluate the farm’s “Trend Adjusted (TA) – APH” option.  Many farms can opt for enhanced insurance protection for only slightly higher premium costs

In a potentially dry season, having a thorough conversation with your crop insurance agent could easily lead to the most important decisions a farm will make for the season.  The following are some very good web sites with crop insurance information:

Soybean Agronomy - SDS

Sudden Death Syndrome (SDS) was first identified in North Dakota in the very southeastern part of the state (Richland County) during the summer of 2018.  In the 2020 growing season, NDSU pathologists identified multiple fields of SDS in the same region.  It is even reported that SDS was identified and confirmed in the northeastern part of the state as well in 2020 (Cavalier County).

The SDS disease has been around since the early 1970’s in the US, with first confirmations in the state of Arkansas in the summer of ’71 .  It’s a type of fusarium fungi that infects the root initially, and produces a toxin that moves from the root tissue through the xylem to the upper portions of the plant.  It is this toxin that causes foliar symptoms to be expressed later in the season (picture).  Another distinguishing characteristic of SDS is the darker colored pith of the soybean stem (top SDS infected versus bottom (healthy) – see picture). 

Sudden Death Syndrome is a root-rot organism that gains favor in poorly drained and compacted soils that remain wet in high rainfall seasons.  As plants deteriorate from the loss of leaf area and effective root translocation, yield impacts can be dramatic. 

Because of how the disease moves in the plant, foliar fungicides are not effective against the pathogen.  Since the fungi originates from the soil and infects the soybean plant early in the life cycle, seed treatments have shown good efficacy.  There are genetic differences in individual varieties to the tolerance levels of SDS, but for our region and the Group 00 to Group 0 relative maturity (RM) zones, genetic tolerances are below average at best. 

Soybean Cyst Nematodes (SCN) are another significant factor in SDS development.  Infection wounds on soybean roots from SCN provide entry points into the plant for the SDS soil-born pathogen.  Scientists have also found that SCN can be a vector for carrying the SDS.

Today, seed treatment utilization, top SCN management, and enhanced field drainage will be the best defense against SDS in the northern 2/3rds of North Dakota and NW Minnesota.  IleVO® fungicide seed treatment (FST) is an industry leading soybean fungicide FST with activity against both SDS and  SCN.  Yield data from 2012-’14 (three seasons) reveals in locations with SDS pressure, a yield increase was achieved with IleVO® at 9.8 bu/ac (see graph).

Sunflower Production Survey from NDSU

This national survey is centered around black bird impacts to the crop, but regardless of your sunflower acre size, history in raising the crop, or bird impact levels, they would like to hear from you.  The survey should take no longer than 10-15 min to complete and will help shape the future of research ideas and topics that go into the crop.  With only 1.6 to 1.7 mil acres annually of sunflower production in the US and Canada, research dollars are limited.  Your input is valued; access the survey here: https://ndstate.co1.qualtrics.com/jfe/form/SV_1UoXI3SKlKGW8PH



Product Spotlight: P8859AM


The next product in our series of new Pioneer corn genetics for the spring is P8859AM.  It’s probably our strongest agronomic new hybrid with above average trait characteristic scores for drought, stress emergence, brittle-snap and late season standability.  It’s medium-tall for plant height and average for Goss’s Wilt at 88 RM (relative maturity).  Yield potential is solid as it should outpace both P8989AM and P9188AM, plus be about ½ to a full point drier.

For a quick review, Pioneer rates their products on a 1-9 scale with 9 being the best/strongest/tallest.  Average characteristic performance scores are typically 4’s and 5’s; below average is 3, and above average strength would rate 6 to 7.  It is fairly rare to see an advanced product with a trait score of 8, but it does happen.  Most all products that would rate below a 3 on any given single agronomic score would not make it through the process to become a commercially available product.

Unfortunately, we’ll only have units of this hybrid in our Pioneer IMPACT or advancement trial plots.  This data will help drive confidence within the sales team for 2022 placements.  If you’d be interested in driving additional data on your farm, we could definitely help plan a strip trial or side-by-side comparisons on your farm.  Please reach-out to myself and/or your local Pioneer agent and we’ll put a plan in place.



Kochia Weed Resistance Management

Here is a good summary of kochia management from the University of Wyoming.  Yeah, I know the agriculture in Wyoming is a lot different than our region, but this particular research was done under high rainfall (irrigation), and crop rotations that included sugar beets, corn, dry beans and small grains (barley or spring wheat).  Sound familiar?  Also, I know that kochia may not be your number one weed concern, but with kochia being a large seeded broadleaf weed, the management tactics that aid in helping control kochia are going to be beneficial against other broadleaf weeds like ragweed and waterhemp.

The research evaluated crop rotations and tillage intensity along with herbicides in managing kochia.  Kochia weed evaluations were done on weed density (plants), seed production per plant, and seedbank numbers. 

In summary, the most diverse the crop rotation (corn-dry bean-small grain-sugarbeet versus corn-corn-corn-corn or corn-sugarbeet-corn-sugarbeet) had the lowest kochia numbers.  Conversely, the sugarbeet crop was identified as having the least ability to compete with the kochia and therefore the corn-sugarbeet-corn-sugarbeet crop rotation led to the highest kochia numbers.

For herbicides, it is no surprise that the old ALS herbicides (i.e. Glean™, Aly™, Express™, and Harmony™) no longer control kochia due to resistance.  Therefore, alternative herbicides and tank-mixed herbicide recipes provided much greater control.  Full tillage was more advantageous than no-till in aiding to keep kochia weed density numbers lower.  Kochia has a short weed seedbank life (approximately two years), making short-term management more impactful.

This article basically confirms that our current practices for sound weed management strategies are on par with leading state university recommendations.  The challenge will be for top producers to find ways to stay ahead of the evolution of weeds, during this time of expanding herbicide resistance.  What will it take for the next decade of weed control to reduce weed seedbank numbers?  It’s probably safe to say innovation, and a continued openness to implement those ideas.

Random Agricultural Facts – Tillage Trends in the US

The other day, I had an inquiry about how much of the US farm ground receives conventional tillage versus no-till.  Well, the closest data I could find was from the USDA and published in September of 2018.  The University of Illinois recapped the USDA publication at this link: https://farmpolicynews.illinois.edu/2018/09/ers-report-tillage-intensity-and-conservation-cropping-in-the-u-s/

Farmer tillage practices vary by crop and region of the US (see chart above), but overall the trend is evolving to more reduced tillage (mulch-till and no-till) in our agricultural systems.  United States wide (chart below), the concentration of “no-till” acres is dominating the reduced tillage class when the wheat or soybean crop is planned.  When corn is the crop being grown, most of those acres are receiving tillage (either mulch tillage, or conventional tillage).  Cotton still has the vast majority of acres under conventional tillage practices (neither mulch-till or no-till).




No-till adoption is greatest in the south and south-central (Prairie Gateway) part of the US where there are warmer soil conditions.  The Northern Great Plains utilizes more no-till in the wheat crop and less no-till in the soybeans – the only region in the US where reduced tillage is under 50% in the soybeans.

Additionally, it was also interesting to note that farm managers implementing no-till were more likely to use cover crops.
