Tips to Increase Your Odds of ROI

Guest blog by Bob Foley, Corn Breeder Like you and I, each corn hybrid responds and reacts to environmental changes. For example, I’m not a bright lights and heavy traffic sort of guy. Vegas is not my happy place. I perform my best in solitude with wide, open green spaces and lots of coffee. Withdraw the coffee, and it affects my demeanor!
Corn hybrids are similar. Think of a situation when a crop emerged perfectly. If adequate rain doesn’t fall, yield suffers. The inverse is also true. When too much rain falls and nitrogen leaches, yield also suffers. Sometimes weeds develop resistance to herbicide, and yield suffers due to competition for nutrients and water.
Many of the practices we implement to push ROI (return on investment equates to yield) have both positive and negative impacts: planting early, pushing populations, field drying, and adopting traits. Each of these practices can swing the outcome pendulum either way:
• Planting Conditions. Planting remains the most critical first step of a great corn crop. You need fit soil conditions. Just the right mix of not too dry or not too wet, no slabbing, and no wet holes allows you to plant better and seedlings to emerge faster. Planting depth and spacing is also key, so it’s important to check periodically.
• Planting Population. It’s critical to plant a hybrid thick enough to maximize returns, but there is also a point of diminishing returns. If the plants don’t receive enough food or water, yield suffers. Consider that every ear you make comes from its own “production plants,” and each plant needs to run at its optimum. Planting population must reflect your field’s history, food availability and soil
type(s).• Field Drying. This choice combines many things, including cost to dry, availability of dryer and storage, as well as your marketing commitments. Pushing a hybrid’s relative maturity (RM) means you’ll harvest it later, which could allow you to experience in triplicate when it comes to field drying versus standability.
• Adopting Traits. Everyone has his or her own position on farming with or without traits, and I tend to be like Switzerland in this conversation. I just want good hybrids. However, I do believe the adoption of traits has changed the way we steward our farms. We don’t walk the fields like we used to and scout for weeds, insects and disease. The concept of “I paid for traits to protect my crop” has somewhat given us permission to stop walking the fields (even more so after pollination). That’s a huge gamble! Without walking the field – or even flying the field – we usually aren’t aware of trouble spots in a field until we sit in the combine seat.
Give a “seat at the table” to emergence, population, standability, traits, yield and genetics. Deal them in, too, because they respond to your management decisions. What can you learn from the 2019 crop that could be a game changer for 2020? Due to the unpredictable outcome of our decisions, it’s always best to play the odds by planting multiple hybrids and relying on multiple experiences. One plot, one year, one environment or one hybrid is not a covered bet. Spread the risk by relying on tried and true practices. Making minor adjustments here and there can reap huge payouts. Making drastic changes, however, is like pushing all your chips in before seeing the cards dealt.
Like I said, I’m not a Vegas kind of guy. I’m all about increasing my odds – and yours – of winning.

Tar Spot

What is Tar Spot?
Tar Spot is a corn fungal disease that has been infiltrating the Midwest within the last few years. Tar spot has the capability to severely impact yields up to 30%. Concern about the intensity of this fungus grows as researchers learn more about it. We urge farmers to scout their fields through harvest for tar spot since this fungus can survive over winter year to year.Tar Spot Identification
Tar spot will show up as small, raised blacks spots, on the upper and lower corn leaves. The raised black spots are also known as stromata. If severe enough, it can spread to leaf sheaths and husks. Typically, it will start lower in the canopy and move upward. Tar spots are usually accompanied with a yellow halo or fish-eye effect around the black spots. Note the stromata, cannot be rubbed off unlike a common or southern rust pustule.
The Importance of Scouting
This corn fungus has nearly made it across Iowa and is continuing to spread in Wisconsin, Illinois, Indiana and Missouri. Tar Spot likes cool temperatures and humid conditions, with prolonged leaf wetness or heavy dew and will concentrate towards the middle of the field. It can cause lodging and hasten maturity.
Final Thoughts
This is one of the variables in farming we continue to learn about. Scout now and start planning for next season. Product selection is key when fighting these variables year to year and important to integrate into your plan for the next growing season.

Adjust Your Harvest Plan to Address Stalk Rot

Many Latham sales managers, dealers and customers have shared their concerns about the excessive rainfall received. Most of Latham Country in the last few weeks have been wetter than normal.
Wet weather brings to mind diseases, and too often we see corn fields with some leaf and stalk quality issues late in the season. I’ve personally seen a lot of Common Rust, Northern Corn Leaf Blight, Gray Leaf Spot and Eyespot this year.
Even with harvest underway, it’s important to continue checking fields and assessing stalk integrity as weather conditions can cause crop conditions to change. Ideally, farmers harvest the driest fields first so crops can dry naturally. This obviously saves time and money, but those plans must be revised if stalk rot shows up.
There are two primary ways to check corn plants for stalk rot: (1) Pinch the stalk at the base of the plant, usually below the first and second nodes. If the stalk pinches easily between your fingers, stalk rot is likely. (2) Take the entire stalk and bend it to a 45-degree angle. If stalk rot is present, the plant usually breaks at the lower part. Do this with at least 10 plants from different areas of your field to provide a good sampling. If stalk rot is present, harvest that field as quickly as possible regardless of the moisture content. The yield that could potentially be lost during high winds or complete rot will far outweigh the extra cost of drying grain.
Weather will, of course, dictate how corn stalks hold up to disease and normal decay. Adjust your harvest plan if needed to harvest the worst first.
