Bouquet Ear - Corn Syndrome
Submitted by Matthew G. Hanson on 11/11/2009
A 4 acre corner of a 40 acre field is exhibiting bouquet ear syndrome with multiple ears per shank. Pulling the husks back reveil a few kernels at most per ear. An occasional plant (5% of total) have near normal developed ears. The majority of the area will not produce any yield. This is a corn field following several years of soybeans. I was told by the seed rep that Aim was used as a burndown with soybeans the year before followed by Roundup. Lumax was apparently applied to corn this spring at 2nd leaf stage. Planted May 5th, and a 98 day maturity variety with several trait stacks. Noticed the soil in this area of the field to be wetter than the rest of the field. I took a video with much greater detail of what the field looks like but will need to find a method to get on-line.

Bouquet ears have been reported more frequently in the last few years. They were first reported in Indianna, Illinois and Iowa. The initial write-up was by Bob Nielson in 1999 (see http://www.agry.purdue.edu/ext/corn/news/articles.99/990823b.html). For a complete discussion of the problem see http://www.agry.purdue.edu/ext/corn/news/articles.06/Bouquets-0912.html.
I hear scattered reports of this syndrome every year, but the acreage affected does not seem to be widespread at this point.
