Dear Clint,
This week, we take a look at regional agronomy reports and key issues for pollination.
Remember to check the agronomy article archives, as we are posting about 40 new agronomic articles every week on the website. |
Western Region Report
|
|
From David Hoy, Western Region Sales Agronomist: Weathercontinues to be a mixed bag as
many areas are receiving rain and wind. The question is do these areas need it
or not. With this extra water, roots don't have to grow as far down. This may
be a concern this fall if we get high winds.
Corn-on-corn ground looks as
good as can be expected, with the early unevenness we saw starting to catch up.
I have been getting a lot of questions on fungicide applications in corn. Now
is the time to get those applicators lined up because, timing is
everything. There are some good links on the left side below that should answer some other questions, check them out.
Soybeans are looking good. Very few diseases or bugs to speak of. I
did find a few aphids in one field that was not treated with Fastbreak CP.

Central Region Agronomy Report
|
 By Tim Jordal, Central Region Sales Agronomist: Rain finally fell in most of Illinois
this past week providing much needed relief too many areas of Central
Illinois just in time for tasseling. While tassels have already
started to emerge in Central Illinois, here in Northern Illinois and Southern Wisconsin, we are about a week or two away for most
fields depending on planting date.
As of now I have not heard of any insect
problems but rootworm larvae are most likely hard at work and may have begun to
emerge as adults so keep an eye out for potential silk clipping in the coming
weeks especially in the earliest silking fields. For those in East Central
Illinois it is also time to start watching for Japanese Beetles as they will
begin to emerge soon and will begin clipping silks.
Here's a few links from the University of Illinois on these issues:

Eastern Agronomy Report
|
|
By Tex Young, Eastern Region Sales Agronomist: Corn rootworm feeding is one of the most devastating things that can happen to corn. These photo of corn roots were from plants taken from a field in Central Indiana.
  This
was the refuge corn that actually had an application of soil
insecticide, however, due to the dry conditions since planting, the
insecticide had very inconsistent effects. This was a field that was
planted late with a conventional corn hybrid without any insecticidal
seed treatment.
The farmer told me that the corn emerged
very consistently and was very uniform until about V4 to V6 stage when
lots of height variance occurred. Digging roots and noticing the
tremendous feeding from rootworms showed why so much growth variance
was noticed.
Needless to say, this farmers fields of CRW traited corn looked very nice and uniform without any inconsistency. Here are a few good agronomy links from this past week:
