How did corn fungicides affect yield this year?

Agriculture.com Staff 10/09/2007 @ 7:31am

Now that the harvest is underway, corn growers who applied fungicides this year are able to better determine how their yields were affected.

In the Crop Talk discussion group at Agriculture Online, central Iowa corn grower "Doolittl" says that in the one test he's done so far this year, his fungicide-treated corn is yielding 30 more bushels per acre than non-treated corn. Last year, he says, after looking at the numbers for 15 check strips, fungicide-treated corn ranged from 10 to 40 bushels more per acre, with the average around 20.

Researchers at Iowa State University are also interested in knowing how fungicides affected corn yields. In addition to compiling data from trial locations throughout the state, growers and contract sprayers are invited to take part. If fungicides were applied to corn with an untreated check strip, yield maps can be sent to ISU along with a form.
