July 9, 2019: Corn Disease Evaluation: Incidence versus Severity and Palmer Amaranth Identification
2019 has brought us many challenges and we are only halfway through!  Frequent rain events will allow the disease inoculum to keep building.  Foliar fungicide application is in full swing in some parts of Ohio.  If you have a grower who undecided about applying a foliar fungicide and wants to evaluate disease pressure before employing an application, you should always look for two things: Disease “Incidence” and “Severity.”
 
July 5, 2019: Watch out on crop growth stages & herbicide/adjuvant mixes!
Mother Nature “flipped” the switch and we are now experiencing “normal” summer temperatures in Ohio.  This quick transition from 70-degree days and 50-degree nights to 90-degree days and 70-degree nights has made crop and weed growth explode in the last five days, also leaving plants with extremely thin cuticles, similar to the outermost layer of your skin.

 
June 10, 2019: Residual Herbicide “Post-Application” Cutoffs and “Prevent Plant” Resources

Residual Herbicide “Post-Application” Cutoff
With the onset of corn planting and the sense of urgency to initiate #plant19, some growers are in the situation of having no burndown herbicide application completed prior to corn planting.  Others have emerged corn and have not applied an herbicide application.  One class of herbicides we do not want to eliminate are the residual herbicides.

 
June 4, 2019: Should I increase my soybean seeding rates? Be on the lookout for BCW!
Should I increase my soybean seeding rates?
We are all aware that some growers are progressing with #plant19, and some are unfortunately not. Planting date is major factor in setting the yield potential of soybean.

 
May 23, 2019: How does a soybean seedling emerge?  What is the proper timing for “head scab” prevention in wheat?
Soybean Germination and Emergence
With many customers planting more soybeans earlier than we have seen in the past, it is also prime time to share information on how a soybean plant develops.

 
May 15, 2019: Where’s your wheat growth stage at? Some parts of Ohio are heading and will be pollinating soon. Be on the look out for foliar disease and FHB!
F.H.B.
Fusarium head blight (F.H.B.), commonly referred as wheat “head scab,” is a common disease we can face every year, all dependent on the environmental conditions. 
 
Wheat in the southern part of Ohio is approaching heading or just headed, which means that flowering will start within 4-5 days, depending on temperature (heads produce small yellow anthers).

May 8, 2019: Do you have large weed populations in your fields? You are not alone. Looking to introduce biology into soil, reduce biomass and boost your herbicide efficacy? 
The USDA/NASS stats reiterate what we are all currently experiencing! Recent data for Ohio says only 2% of Ohio’s projected corn acreage was planted - compared to 20% last year and 27% for the five-year average. Frequent rain evens, followed by below average air temperatures has kept the planting process to minimal levels, yet the weeds keep growing!

 
April 30, 2019: It’s Wet And We Are Delayed With Planting: How Should We Adapt Our Burndown Herbicide Program?  
The Ohio State University Extension takes a look at questions on how to deal with burndown herbicide treatments in delayed planting situations. Click here to view the article.
April 26, 2019: Is Your Planter Ready For 2019?  Here Is A Quick Refresher.
1. Level the Planter.
Check your hitch height. Make sure the planter’s tool bar is level (vertically) or running slightly up hill. When planters tip down, coulters run too deep and the closing wheels run too shallow. 

2. Check Tire Pressure.
While it seems basic on a ground planter, this can be the difference between a good solid stand and one that is thin due to drive tire slippage. 

3. Check Brushings and Parallel Linkage.
Worn bushings increase row bounce which increases seed bounce. Stand behind the row unit and wiggle it up and down and back and forth checking to make sure bushings are tight.
 
April 18, 2019: With the on-set of corn planting, the next question you get is “How long does it take corn to emerge?
A Few Items to Keep in Mind
  1. Imbibe 30-35% of kernel weight in water           
    1. Imbibitional chilling-absorbing cold water and causing emergence issues
    2. Important to have good seed to soil contact 

  2. Soil Temps at least 50 degrees Fahrenheit
    1. Radical elongation
    2. Seminal roots- cease growth at V3 and nodal roots (a.k.a. “adult roots” begin to emerge
    3. Energy is coming from endosperm (a.k.a. the seed reserves) 

  3. VE-Mesocotyl pushes Coleoptile through the soil surface
    1. 90-120 growing degree day’s (GDD) to emergence
    2. Crown and Nodal root are at .75 inches below soil surface

April 10, 2019: Still questioning your winter wheat stands? To destroy or not to destroy...that can be a challenging question. 
Numerous inquiries have come on whether or not to proceed with managing thin wheat stands for yield. Over the years, I have seen really thin stands perform very respectfully well. Wheat is surprisingly a very resilient crop.
 
However, if you have large holes within fields that are completely missing stands, then those are easier candidates to terminate and transition to soybeans or corn. Sometimes wheat stands in linear rows can be deceiving, especially when there is brown tissue within the row. Be sure to take adequate stand counts to quantify your yield potential and to determine the best course of action.

April 5, 2019: Curious on StandUp Fertizol family, starter fertilizers and BioBuild BioComplete mix timings
How long prior to use can PCT | Sunrise® StandUp® Fertizol® and Fertizol® Zn be mixed with starter fertilizers? Secondly, how early before applying BioBuild™ BioComplete can it be mixed with water? 
From an operations standpoint, we are aiming for a “just in time” delivery of these products to the farm when they are premixed at the plant. Ideally these products should be kept separate from the starter fertilizer and added “just in time” for planting use at the farm.  

StandUp Fertizol and Fertizol Zn
  • When mixed with starter fertilizer, the product should be applied within 24-48 hours.
  • These products are very strong and have the ability to start pulling impurities out of the starter fertilizer (e.g. 10-34-0), and occasionally can cause solids to form in the tank. This is why we recommended using as soon as possible after mixing.
  • ​When using StandUp premium starters with the Fertizol family of products, application is recommended as close as possible after being mixed. As with most product mixes, agitation/recirculation is recommended prior to application.
BioBuild BioComplete
  • Should be protected from freezing.
  • Ideally when mixing with water, it should be used as soon as possible.
  • If a rainout occurs after mixing, and the solution has to sit in a tank, try to avoid direct sunlight as much as possible when waiting to apply.
  • As a reminder, there are live organisms in this product which will continue to reproduce. Keeping out of direct sunlight slows this process, therefore minimizing solids formation.
