"We’re not giving-up, and you’re not going to give-up either!” – Larry Bird, NBA Hall of Famer

 It was halftime of the Boston Celtics game at “The Omni” Coliseum in Atlanta (January of ’86), and the visitors found themselves in a big deficit – 22 points (48-70).  The 1980’s era of basketball did not have regular 20-point comebacks like today, but Larry Bird still found a way to get fired-up to start the 3rd quarter and he informed the referee to stay mentally sharp as well despite the scoreboard reading.  I’m not sure what was said during the intermission by head coach K.C. Jones, but the Celtics did claw their way back into the game throughout the third period.  In the fourth quarter, the Celtics were able to force overtime and found a way to complete the night with a 3-point win!  Bird finished with a game-high 41 points, including four free-throws in the waning moments to seal the game, to go along with 7 rebounds and 6 assists.  Dominique Wilkins led the Atlanta Hawks with 36 points, 7 rebounds, and 3 assists.

Well, it’s probably halftime of our row-crop growing season (or a little past), and just like in basketball, the second half is probably the most important.  How will the crops endure the mid-summer heat?  Will we get enough rain to maintain yield expectations?  Will the corn and soybeans make maturity before a killing frost?  Or maybe the markets will provide a harvest rally?  Many questions remain and many potential scenarios could develop.  Despite the late start to the growing season, no one is giving-up on this crop today (we have way too much money invested), and we’re showing our usual excitement for the season to play out and the harvest to begin.

If you have any ideas for newsletter topics, feel free to reach-out for discussion.  As you can tell from my history of articles, most ideas are welcome.  This month’s list includes an update on regional weather, continuing IDC, soybean insects and insecticides, as well as some other items to keep it interesting!

 

Weather

With my estimated date of May 24th as a regional mid-point of corn planting for 2022 and most of the corn in the pollination (VT/R1 growth stage) currently, let’s evaluate our corn growing degree day (GDD) outlook.  Here is our current GDD position in 2022.

 


Next, we should compare how the GDD’s stack up so far in 2022 versus the prior 30-years.  When it comes to comparing seasons, I’m not a fan of comparing prior years with the current year under the same late plant date.  Yes, every year is different, but if we would like to evaluate GDD comparisons, we should compare on a more average plant date.  Therefore, I’ll use the average start date of May 10th for our comparison.  As you can see from the figure below, even though we had basically a two-week late start to corn planting in our region, we have caught back-up to the 30-year average with a give or take of two to three days depending on specific location.  Southeastern North Dakota would be the exception to this where they are consistently seeing a 4-6 day advantage in GDD’s during 2022 so far versus the 30-year average.


 

Lastly, what can we expect from this point moving forward to the end of the growing season for GDD accumulation under an average first frost scenario (September 25)?  For our northern regions of North Dakota and NW Minnesota, we should see approximately 700-800 additional GDD’s yet for the season.  When we add this to the already 1050 to 1200 GDD’s already accumulated since May 24th, we should be in a great spot to have our 75-85 RM corn hybrids at (or very near) physiological maturity (black layer). 

 

Overall, we are currently in a spot that is very favorable considering where we were at the end of May and considering the consequences of a short growing season.  Add to this the favorable precipitation we have collected for the growing season to date, our crops are set-up to produce significantly above average.

Corn planted at the end of May or first week of June will most likely need the entire month of September to remain frost free to get close to physiological maturity.  Given the situation, these fields have a very good shot at producing quality grain with respectable yields – albeit with a likely need to manage for a late harvest and above average grain moisture content.



 Late Season Insects

We’re starting to see more soybean aphids in the region, and with the presence of grasshoppers in many of our soybean fields the situation deserves a bit of conversation.  First, we must remember from 2017 that most of the aphid populations in our region are resistant to some of the pyrethroid insecticides (specifically lambda-cyhalothrin or Warrior®).  Second, with the loss of Lorsban™ (chlorpyrifos) from the EPA, and third the fact that most of the non-pyrethroid soybean aphid insecticides target only sucking/piecering insects (which grasshoppers are not), we see the need for a tank-mix or “in the jug” mix to control both insects (soybean aphids and grasshoppers).

Corteva’s crop protection team has come to the table with their option of Ridgeback™.  It’s a “in the jug” mix of a pyrethroid (bifenthrin or Capture™) for the grasshopper control, and sulfoxaflor (Transform® WG) for control of the sucking/piercing insects like soybean aphids.  Bifenthrin is known to provide enhanced residual control, so be sure to visit with your preferred crop protection specialist for details.

IDC - Still Affecting Soybeans

It seems like the Iron Deficiency Chlorosis (IDC) in the soybeans won’t let-up this year.  Yeah, it’s getting better these past couple of weeks, but many fields around the region are still showing signs and symptoms plus we’ve lost some plant numbers in places.  A combination of the continued wet weather, high soil nitrogen carryover in fields, our high soil pH’s, and significant levels of carbonate/bicarbonate in the root zone is all significant to the situation at hand.

Now, we could be seeing some infestation of soybean cyst nematodes (SCN) which can portray similar symptoms, but overall, SCN presence throughout NE North Dakota and NW Minnesota is fairly minimal, plus we’ve had to battle against IDC since soybeans came into our region.

The management practices in soybeans for IDC remain the same: variety selection, improve drainage, and implement the use of iron chelate  in furrow at planting time.  Products containing ortho-ortho Fe EDDHA (i.e. Soygreen®) are the best choice as they contain the water soluble and plant available ferrous (Fe++) iron.  I’ve only seen significant yield responses to chelated iron with a planting time application and full use rates under heavy IDC pressure.  Post-emerge applications do show visual recovery from the IDC but have not led to significant yield response or ROI.  Today, there are both granular and liquid formulations available on the market for chelated iron products.

Below is great photo showing one-row plots of different soybean genetics with susceptibility/tolerance to IDC.

 


 

Dicamba or 2,4-D Injury?

With the generally lower temperatures and higher humidity’s of the 2022 growing season (versus 2021), we are not seeing as much herbicide drift and volatility impacting susceptible soybean varieties.  However, we are seeing more herbicide carryover of clopyralid (Stinger™) than prior years due to the dry conditions we experienced last season and thus the slow breakdown of clopyralid in our lower organic matter soils.  Stinger™ carryover symptoms on soybeans looks very much like dicamba injury, but typically you can find a spray pattern where some overlap has occurred where the injury will be more pronounced.  Stinger injury will affect both RR2Xtend and Enlist-3 soybean varieties.

The following articles nicely describe the difference between 2,4-D injury and dicamba injury on soybeans:

Grand Forks FuFeng Corn Mill Project

Well, living locally here in the Grand Forks, ND area, I can easily report that the small city has definite concerns with the local political leadership as it relates to the development of a wet mill corn plant for Fufeng Group.  The topic is starting to gain some national headlines as well from many different media outlets.  Many articles can be found with a simple internet search. 

The web-linked DTN and NY Times articles from mid-July outline many of the pros and cons:

·         $750 MM project that would consume 25 million bushels of corn per year.  At 150 bu/ac corn production output, it would equate to 167,000 ac of corn needed annually from local producers.  For comparison, the county of Grand Forks had 798,500 acres of total farmland in the 2017 USDA AgCensus

·         The wet corn milling plant is forecasted to employ about 1,000 construction jobs and 220 people full-time once the plant is built and operating, providing numerous job opportunities

·         Concerns about the city’s infrastructure to handle the increased demand in water, and traffic to support the project

·         Concerns around pollution into the Red River and odor into the atmosphere for local residents to endure

·         Concerns around the amount of tax being waived while significant infrastructure (water, roads, natural gas, etc) needs to be enhanced to support the wet mill corn plant

·         Concerns with prior human rights violations by Chinese companies (including FuFeng) in their domestic and international business dealings

·         National security concerns over the proximity of the Chinese plant to the local national Air Force base and the potential for espionage

·         Concerns with the local government following protocols at the federal level for international investment into the USA

·         Concerns about the local government with annexation of land, adequately allowing the local public to voice their concerns, and allowing the public to have a ballot vote on the issue.
