INSECT UPDATE

 

Soybean Aphid

You can find a wealth of information on Soybean Aphid in the Special January 23 Issue of the ICM Newsletter, 24 pages, full color.  The ICM Newsletter is posted at:

http://www.ipm.iastate.edu/ipm/icm/.

 

 

DISEASE UPDATE

 

SCN Yield Variety Trials Available

The 2005 ISU SCN-resistant soybean variety trial report is now available.  This report (as well as the reports since 1996) is available at www.isuscnvarietytrials.info or call the Department of Plant Pathology ( 515-294-1741) and request a hard copy.  These variety trials include the measure of SCN levels in the trials, which allows you to evaluate not just yield, but yield under a defined level of SCN presence.

 

Soybean Rust

The recent cold spell in the south should have taken care of some of the kudzu, reducing the overwintering sites for Asian Soybean Rust. The next issue of the ICM Newsletter will feature soybean rust. For the latest map on where rust has been found this year see http://sbrusa.net/.

 

White Mold

White Mold was very severe in many soybean fields in 2004.  Many of those fields are scheduled to be planted with soybeans again in 2006.  With the high level of inoculum in those fields, producers will want to especially evaluate the genetics to be planted.  There is no good resistance, but there are definite differences in susceptibility, or partial resistance.  For more information on White Mold management see the Plant Health Initiative White Mold web site at http://www.planthealth.info/whitemold_basics.htm.

 

 

STORED GRAIN

 

Stored grain should be checked every one to two weeks this winter.  The need for inspection more frequently than normal is because much of the grain put into storage last fall was in less than ideal condition.  Thin and/or cracked testas (seed coats) cannot protect the grain from molds as well as thicker or intact testas.  Furthermore, some of the grain was already infected by molds when it went into storage.  Compounding the problem is the potential for light test weight grain to “signal” grain driers to move the grain before it has dried to the intended moisture content.  So some grain is much more vulnerable to spoilage than usual this winter.

 

A great inspection strategy was printed on pages 23 – 24 of the May 7, 1997 Iowa State University Integrated Crop Management Newsletter; this article can be viewed at http://www.ipm.iastate.edu/ipm/icm/1997/4-7-1997/storedcorn.html.
