Do you have your fall fertilizer plans in place?? Having VRT Rx's at your retailer ready to go before harvest starts makes for getting fertilizer on a field a simple phone call "Just finished harvesting the Jones Farm... go spread it"..
With tight margins be sure your Yield Pyramid foundation is taken care of!!
Yield vs fertility levels from hundreds of locations across the northern corn belt shown below along with what variables were most important for yield. Visit with your local Pioneer Sales Rep with any questions.

Pretty drastic improvement on management tank mixing both Liberty and Enlist to control waterhemp. Thanks to Dr. Werle and his staff for sharing this!
Liberty, Enlist One, Liberty + Enlist One?!
Check what we are learning from @ZaimUgljic’s #waterhemp management project.

Disease Prediction Model most recent run. GLS risk increasing rapidly and is becoming much easier to find in fields. Tar Spot is picking up the pace as well.
Typically don't put in Southern Rust.... but Hurricane Beryl came ashore right where Southern Rust was a hot spot and will likely move spores into the corn belt. Same with Northern Corn Leaf Blight (NCLB).
Early planted fields in my area (prior to April 25th) are showing spray now in the Fungicide Timing program. Please visit with your Local Pioneer Sales Rep about your fungicide plan.

DEAD OR ALIVE??? A way to check if your waterhemp is going to perish if it looks alive yet when it was sprayed a couple weeks ago....
Pull the plant out and break the stem in half were the soil line was. If brown and mushy then it is having the nice slow painful death it deserves!!

Perfect storm showing multiple effective MOA's is the way to manage CRW, just like weeds and diseases. Using just one MOA (trait, insecticide, rotation) can likely lead to failures. Using two or three "MOA's" is holding up.
Late planting, early CRW hatch that is compressed with rapid GDU accumulation along with poor root development due to wet soils has some fields with issues.
Apparently the larva now have gills like fish and cannot be drowned!!
Plant on left has 3 MOA's... other's a variety of only one..

No. This 4th of July, the float test isn’t about sitting in a tyre tube and floating down the river …. Unfortunately!
Now is a great time to check corn for rootworm feeding, especially if you think you might have a variant! One method to check for pressure is by doing the float test! @erinwhodgson talks more about that here: youtu.be/o4PIPf-tOkI?si=-dPZ…. #ISUCrops @ashleyn_dean

Whoomp! There it is! What to do about Tar Spot of Corn in 2024 @fieldprophet badgercropdoc.com/2024/07/02…

I found the first Tar Spot in Wisconsin this year in Pepin County near Durand. Weather continues to be favorable for Tar Spot development. Corteva Tar Spot Model is tracking it well.

I’ve always used “practical” agronomy indicators for potential insect or diseases. Common rust is here! In #corn it is a good measure of conditions that are right for other more yield limiting diseases to show up. The conditions are right. Be prepared @PioneerSeeds

All this humidity has me thinking white mold control is just around the corner. Viatude is the one to use this year! @PioneerSeeds

Tar Spot found in Tama County, IA today. V7 corn. Record early infection for Iowa. No need to overreact with fungicide now. Still a good reason to keep scouting the rest of the summer and monitor progression ahead of normal VT-R2 app timing.

Alfalfa weevils are out!
👉🏼Cut on the early side
👉🏼Scout the new regrowth- larvae and adults will be hiding in the crown
👉🏼Spray if needed shortly after if pressure is high

Armyworm alert!!!!
Fields in Delaware and Clayton counties with cover crops are starting to show very high levels of armyworm hatches in some locations. Insecticides with termination 2-4 weeks ago have ran out. Get out there are scout tomorrow after the rains end tonight!!!

Finding some fields that might require asking grandpa how to run the rotary hoe.
In many cases If you have a heavy crust and plants aren’t turning around yet, you are better off to run a rotary hoe and reassess in a week than rip up April planted corn

“Tractors tractors everywhere, mud it in cause we don't care"
-Probably Dr. Suess if he lived in lowa.
All reality, I get weather constraints but please still spend time evaluating cultivator & planter pass
Seeing lots of furrows that are closed on top & slotted underneath.

Showcasing the head start that early planting has so far. This is all from no-till fields (with aggressive trash cleaners) near the I-80 interstate latitude in Central Iowa.

Two great slides that show yield comments for corn and soybeans and how we have to think about management at these times to maximize yields. What are you doing to achieve this in 2024? Thanks to Michigan State University for info! #ontag #AgronomyManagementMeetsCropPhys

Annual reminder to GET OUT AND DIG this planting season!
@AgronNateL & I spent the early part of our week with reps using this furrow board to review common issues we find and how to avoid/correct them.
See below if you want a refresher too!

Should we be planting, and when should we stop?
I've gotten a handful of calls the last two days on when is a good time to stop planting ahead of this rain on Tuesday.
A colleague of mine says it best: “ Mr. grower, what has been your experience in the past planting early into warm, fit soils?”
Oftentimes the answer is, “turned out to be my best corn, despite being cold later on.”
When it comes to rain this time of year, certainly a concern is the temperature of that rain.
First, Tuesdays rain looks to be a "warm" rain. 👍🏻
Second, the chart attached shows how much water it takes to germinate a seed relative to the weight of the seed itself. This is then plotted over time (hours).
Interestingly for corn, a good amount of this happens in the first 30 to 90 minutes and by 10 hours, 80% of the water that it will take up has been taken in.
Also of note, 90% of the water a soybean seed will imbibe is taken up in just 4 to 5 hours!
Planting today is certainly not without risks, but leaving the planter in the shed carries risk as well.
Bottom line: All risks considered, I'm VERY comfortable keeping the planters rolling as long as the ground is fit.
Have a great Sunday - Stay safe out there!
