Farm Progress

September crop progress from Midwest agronomists

Read state reports from Winfield United agronomists regarding corn and soybean issues as of late-September 2018.

This fifth report of 2018 from Winfield United agronomists in eight Midwest states show corn and soybean harvest well underway, thanks to accelerated heat units that helped most late-planted crops catch up.

Current Winfield United agronomist recommendations include:

·       To reduce soybean disease risk farmers should consider a full complement of seed treatments, avoid planting bean-on-bean or choose varieties resistant to these diseases.

·       Perform stalk push tests in all fields to determine harvest order. Don’t let nature do the drydown where stalks are starting to weaken.

·       To manage SDS pressure in soybeans next year, select seed varieties that are tolerant to the disease and use seed treatments to give added protection.

·       Farmers harvesting weed-ridden fields should examine carefully what adjustments should be made to next year’s herbicide program. Postharvest burndown applications should be considered to start next season with clean soybean fields.


Here’s a brief highlight by state.

Illinois: Yields so far range from very good in most areas, to below expectations in dry areas along Interstate-80 corridor.

Indiana: High levels of crown rot have put corn stalks at lodging risk and ear rot damage, so those fields should be harvested first.

Iowa: Recent rainfall is slowing harvest in numerous areas. Yields are trending on par or slightly higher.

Michigan: Wet weather delaying harvest and drydown; crops conditions are highly variable. Tar spot in corn occurred in numerous counties.

Minnesota: Corn and soybean harvest is finally underway, with yields looking average to slightly above average. Corn stalk rot and SDS in soybeans are big concerns.

Ohio: Northern and eastern parts of the state are slightly behind due to crop maturity. Corn stalk integrity is a concern as harvest continues.

South Dakota: Harvest is slow in some wet areas; corn stalk rot must continue to be monitored.

Wisconsin: Harvest continue slow especially in northeast, but underway in south. Some tar spot in corn in southern counties. White mold appeared across the south, but less drastic this year.
