LG Agronomists Provides These Scouting Tips For Getting Ready For Harvest

As the growing season winds down, LG Seeds Agronomist Mark Grundmayer says corn farmers in the West will focus on which products handled stress well.

WESTFIELD, Indiana – Scouting fields ahead of harvest helps farmers avoid the hassle and slowdown associated with downed corn. “Avoiding those issues limits time in the field, saving them fuel, time and labor,” says Justin Schneider, an LG Seeds agronomist in Michigan. “Natural gas prices are extremely high, and the best way to leave your corn out there in the field the longest is to scout.”

The potential is certainly there for stalk issues in Michigan and other areas of the country that have dealt with heat and dryness. That includes dryland and irrigated corn farmers in Nebraska who withstood a blustery spring followed by summer heat and dryness, says Mark Grundmayer, an agronomist with LG Seeds in the state. He says hot nights during pollination and 90-degree temperatures as the calendar flipped to September won’t help the situation.

Start Scouting now and keep at it

Now is a great time to start scouting fields for potential harvest issues, the agronomists say. After establishing that baseline, farmers should check fields every week to 10 days. “And then once we hit black layer, get out there and assess to prioritize fields for harvest and be as efficient as possible,” Schneider says.

LG Seeds Agronomist Justin Schneider recommends farmers assess fields every 10 days as harvest approaches.

“If you are in a drought, plants start to cannibalize themselves from the ground up a bit earlier,” Schneider warns. “Those farmers will likely be dealing with some stalk lodging issues.”

“Under any kind of stress, whether that’s stalk rot, green snap, a late hailstorm or disease-causing loss of the leaf area, we want to get as much harvested while it’s still standing as possible. That might mean an early harvest,” says Grundmayer.

Corn tends to have the most stalk lodging issues once it dries to the low 20s or high teens, according to Schneider. “If you see some problematic-looking fields, consider harvesting when moisture is in the mid-20s.”

Evaluate stalk integrity with a push or pinch test

A push or pinch test can help identify problem fields. Schneider explains the push test as follows:
“Once you hit black layer, walk through your cornfields, stand next to the cornstalk and push it an arm’s length away. When you let go, you hope it comes back and hits you in the nose. If it kinks, breaks or falls over, assess what percent is doing that. If it’s 5% to 10% of the plants, you may need to harvest that field sooner than others.”

With the pinch test, Schneider explains a farmer simply pinches the cornstalk from chin-high down to the bottom couple of nodes on the cornstalk. “If you’re able to pinch it together with ease, that’s telling you the stalk is hollow inside. If threatening weather (e.g., high winds) is forecast, you may want to get out there and harvest that grain a bit wetter than you normally would.”

Besides prioritizing fields and possibly moving up harvest, farmers with downed corn should adjust the combine so it picks up all that it possibly can, in addition to making changes to account for a smaller kernel size caused by drought. “There’s a lot of money on the line, so you don’t want anything riding out the back,” Schneider says.

If a field has a lot of lodging issues, recognize the threat of volunteer corn the following season and adjust rotation and herbicide plans accordingly, he adds.

Review and improve

The reasons for scouting your corn crop late in the season go well beyond harvest. “Late-season scouting is like watching game film,” Grundmayer says. “It gives you a chance to evaluate things like your fertility program, fungicide decisions, hybrid selection and weed control. You can assess what went well and where changes are needed.”

When it comes to selections for 2023, Grundmayer says farmers in the West are going to be focused on which products handled stress well, noting there isn’t a lot of disease in his area due to the hot, dry season. “Ultimately, it’s going to come back to stalk quality and whether or not a hybrid was able to handle stress.”

Grundmayer says LG5700 “has maintained good plant health and stalk quality, despite heat and dryness.”
