Here are some common corn post herbicides and their cut off stages/sizes.
Remember glyphosate is 30 inches or V8.
In the comments is a link with a video on determine growth stage after V5.
Coming off the added saturation stress let’s not try and add more stress as V5-V8 is critical period for ear development. If you can afford to let your plants have a couple days to regroup before asking them to metabolize herbicides that would be ideal.

We are about to exit the “ugly duck looking crop phase”!
As a reminder it takes 82 GDU’s for a new corn leaf to form and 75-100 GDU’s for a new soybean trifoliate to form. For the past week I am guessing we are around maybe 42-50 GDU’s total. Good news is after today we get back into double digit daily GDU’s and a week from now we should have accumulated just over 100 GDU’s so sit tight things are about to get growing and green up and our best stands we have seen in a long time will look really good in a week!
We normally see this every year, it’s normally just 15-20% of the crop not 90% of the crop planted going thru this phase.

Here are two excerpts from Bob Nielsen’s timeless article about young corn in the transition phase. Read and see if it has a familiar ring…

Every year, for the first five weeks or so after corn planting is finished, the guys down at the Chat 'n Chew Cafe complain royally about the looks of the crop. It does not matter whether it was an early planting season or a late planting season. Gripes about uneven stands, poor color, and slow growth waft over the tables as everyone airs their concerns about the looks of their neighbors' fields.

READ THIS. During this important transition from dependence on kernel reserves to dependence on the nodal root system, corn seedlings are easily sidetracked when growing conditions are not adequate for maximum photosynthesis and rapid development of the nodal root system. Consequently, the appearance of corn seedlings during these early leaf stages can be downright ugly during extended periods of cloudy, cool weather. Throw in some excessively wet soils plus a little soil compaction plus a pinch of frost damage and you have a good start on a recipe for "crappy" stands of corn. The best remedy for most fields of yellow-green corn seedlings suffering from the effect of "crappy" growing conditions is the return of ample sunshine and warmth.

You probably woke up to some frost this morning. Some of our electronic weather stations recorded lows of 36 degrees around 5:30am. See pictures for more info about soybeans and corn, but hopeful they will be ok. Will know more towards end of the week after we get several warmer days.

Last year we planted some soybeans in March (14th) and…………..see photos they are really going to test your patience! For 13 weeks they didn’t look to hot and wasn’t till September until you really knew if you did the right thing. These turned out to be pretty dang good! Honestly at 9 weeks post planting they looked pretty similar to our April planted, but had more nodes and more flowers.
Moral of the story make sure your soil conditions are in good shape first off before you think about it. Second if you ain’t got the patience now you’re going to have to be patient with them later “these things are slow” “these beans aint growing” “they ever going to close the row”
Thirdly stay safe!

We receive many calls this time of year seeking advice on whether it is a good idea to be planting or not. The first factor to consider should always be soil conditions. Soil temperature and the weather forecast should also be considered. Research by the University of Nebraska-Lincoln aims to answer the question, “How many hours after planting have to occur before an anticipated cold snap to avoid chilling injury to soybeans?”

There are two water uptake phases that occur in a germinating seed: imbibition and osmotic. The imbibitional phase is an initial period of fast water uptake that hydrates cellular membranes in the seed to a functional state. The seed is more subject to chilling injury during the imbibitional phase of water uptake. Other research has shown that imbibitional water uptake is faster with warmer compared to colder temperatures.
In the research conducted by University of Nebraska-Lincoln, similar emergence to the control occurred when soybean seed was in 60F soil for 8 hrs before a “cold snap” of 36F was introduced to the seed. On the other hand, planting into cold soils of 36F and then quickly warming (within 2 hrs) to 60F resulted in final stands of about 50% of the 60F control. This highlights the importance of ensuring that first “drink” of water for the seed isn’t a cold one. We always recommend planting into warm soils and prefer a warming trend in the forecast for the best chances of successful stand establishment.

St. Pattys Day cold snap caused some wheat to go down, back and check on it in 7-10 days if you have seen any.

Burndown Herbicide Applications: What You Need to Know
Purdue's w**d science team shared updated data reminders for successful burndown applications. Below are the key takeaways. For the full article, see the link at the end of this section.

Key Takeaways
Temperature matters. For postemergence herbicides to work effectively, plants need to be actively growing. Aim for daytime temperatures in the 50s–60s°F and nighttime temperatures above 40°F.
Residuals can antagonize glyphosate. When applied under cool or otherwise unfavorable conditions, certain residual herbicides—including flumioxazin, metribuzin, sulfentrazone, and atrazine—can reduce glyphosate activity on grasses such as wheat, cereal rye, and annual ryegrass. To avoid reduced control, either increase glyphosate rates or apply products separately.
Biomass interception limits effectiveness. Heavy cover crop biomass can prevent residual herbicides from reaching the soil surface, reducing their ability to perform as intended.
Use maximum labeled glyphosate rates for the most consistent burndown results.
Use the RIGHT additives surfactants play a critical role in attaining maximum control utilizing the high end of recommended rates of crop oils, methylated seed oils, and/or nonionic surfactants.

As winter begins to loosen its grip and fields start to show signs of green, many growers, agronomists, and applicators are looking for the earliest opportunity to make burndown applications, especially in no-till systems.

Planter Preparation for Spring: A critical start to any crop is the performance of your planter. Now is the time to start checking your planter. Here is a good article in the agronomy research summary that gives a step-by-step overview of what to look for when doing a planter assessment.
