Disease Issues Popping up in Iowa Due to Late Season Rains

August 25, 2016 10:33 AM

The Pro Farmer Scouts are heading through Iowa into Minnesota today. Scouts are hoping the Iowa corn crop can carry some of the trouble spots in both the Eastern and Western legs.

During a year when drought is a concern, most farmers hope for August rains. While it’s helping crops finish in Eastern Iowa, it also may be hurting it.

“We have had plenty of rain. We could use some sunshine,” says Davenport, Iowa farmer, Darin Engelbrecht.

Davenport, Iowa farmer, Darin Engelbrecht says the crops in his area near Davenport looked consistent all growing season, until roughly twenty days ago. Cooler weather and late rains can take a break.

“We are a little over four inches with last night’s rain. I think we’re over four and a half inches above what we typically get here in August,” says Engelbrecht.

Now diseases are popping up in his soybeans.

“Compared to last year, I think with the disease, it doesn’t look as good as it did a year ago,” says Engelbrecht.

That includes white mold.

“Healthy bean plants seem to be podding well. The unhealthy plants are not so good,” says Engelbrecht.

There is also sudden death syndrome. That’s something he hasn’t had much of during the last two years. It’s enough to change his attitude late in the season, even though it’s only impacting a small portion of his field.

“There are a lot of beans here. So, how the sudden death is going to impact is going to be tough to tell. I’m not sure how the end product is going to be but there’s enough variability in these beans that the top end may have been hurt” says Engelbrecht.

The corn crop however is holding.

“Our crop was better in 2015 than 2014. So, I think this is as good or maybe even better than 2014.” says Engelbrecht.

USDA is projecting a larger corn yield for Iowa this year, pegging a statewide average of 197 bushels per acre in its August report. That’s five bushels per acre high than last year’s final number.

“I definitely believe it’s going to be a good crop. Is it going to be the bin buster? Just depends on how it finishes,” says Engelbrecht.

As Engelbrecht walks through wet fields, he holds high expectations his state is on track for a big year in 2016.

Engelbrecht says he’s received rain about a dozen out of the last 24 days. He says there is some disease issues in the corn. He says there isn’t much tip back and depth looks good so far.
