2012 Ohio Corn Performance Test Preliminary Results Now Available On-Line

Results from the 2012 Ohio Corn Performance Test are now available on line at: or

Single and multi-year agronomic data is currently available for all sites and regions for 2012.   The results can be accessed by following the links above.  Additional information regarding the growing season, evaluation procedures and traits will be available soon.  Additional hybrids will be added as soon as marketing information becomes available, as will the combined regional tables (which are especially helpful in assessing hybrid performance across locations).

Ohio Soybean Performance Trial Results Available Online

The 2012 Ohio Soybean Performance Trial Results as a printable (pdf) file of results in now available at:  and the searchable sortable web page should be available next week at

 The purpose of the Ohio Soybean Performance Trial is to evaluate soybean varieties for yield and other agronomic characteristics. This evaluation gives soybean producers comparative information for selecting the best varieties for their unique production systems.  For each entry, yield, relative maturity, plant height, seed size, and protein and oil concentration is given.  Varieties were evaluated at six locations in northern (Henry and Huron County), central (Mercer and Delaware County), and southern (Preble and Clinton County).  Soybean varieties were entered by type (conventional/Liberty Link or Roundup Ready) and maturity (early or late) for the Roundup Ready varieties.  Soybean yield ranged from 20 to 86 bu/ac with an average of  63, 54, and 62 bu/acre in the north, central, and south region, respectively.

Reporting Web Site for Overwintering Brown Marmorated Stink Bug

Reporting Web Site for Overwintering Brown Marmorated Stink Bug

We (Jim Jasinski, and Celeste Welty) have been reporting on the invasive brown marmorated stink bug (BMSB) for a few years in this newsletter, and this past growing season we saw significant pressure in a few soybean fields (see the 2012-27 issue of CORN). In addition to being found in field crops, fruit and vegetable fields, these stink bugs are also known to invade homes, apartments, businesses, barns, and other man-made structures in the fall. To see an updated map of where BMSB has been detected in Ohio crops, follow this link: Because detections in buildings often precedes invasion in nearby crop fields, it is important to collect reports of stink bugs inside buildings.

While finding these bugs in homes may be unsettling to residents, reporting the finds does allow us to get a clearer picture of their distribution in Ohio.  If you see BMSB this winter or spring in your home or other structure, use this OSUE site to report it:  The report form has 11 questions regarding location, number of insects, time of invasion, and contact information. 

BMSB can be identified by alternating black and white bands on the antennae, and black and white bands along the edge of the abdomen that shows under the wings, as well as faint black and white banding on the legs (images can be found at our Ag Crops Insects page under the soybean tab, To confirm the presence of BMSB, please send your contact information along with a few dead specimens in a tissue padded pill box or other small container to: BMSB ID Program, OSU Extension, 1512 S. US Highway 68, Suite B100, Urbana, OH 43078.

As this new pest expands across Ohio, it is critical to understand its distribution to target future scouting and management. We will run our Ohio Soybean Council funded soybean BMSB scouting program again next year to track its march across Ohio.

Fall Herbicide Treatments - Just Keep on Spraying

There is still time this fall to apply herbicides for control of winter annuals and marestail, and the weather this week makes it an ideal time to do so (this could in fact be a good excuse to get out of the house when extended family starts to wear on you).  Regarding the question of how late fields can be treated, we have applied well into December under cold conditions and still maintained control with effective treatments.  Applying under cold conditions slows the rate of kill but this is not an issue for fall treatments anyway, since the goal is to have fields free of weeds by early spring.  We have had some cold nights but no extended periods of freezing weather, and it appears to us that the winter weeds that are targets of fall applications are mostly green and healthy.  A few other reminders:

- there is no need to include herbicides with residual activity at this point, since emergence of additional plants is largely finished for the fall.  None of the residual herbicides except products that contain chlorimuron (Canopy, Cloak) provide control of weeds that emerge in the spring.  So if you were adding metribuzin or other residuals for control of weeds that could emerge later in fall, these can be omitted.  Note:  metribuzin plus 2,4-D does control most emerged winter annuals so that is still a viable option even where residual is not desired.

- we have heard a lot about the use of 2,4-D/dicamba premix products this fall, possibly due to availability or price.  This broad-spectrum mix can be weak on a few weeds, and dicamba has not been an especially effective cold-weather herbicide in our research.  We suggest the addition of some glyphosate, metribuzin, or other herbicide to 2,4-D/dicamba treatments, especially for late fall applications in cold weather.

- a reminder that fall is the most effective time of application for control of wild carrot and poison hemlock.  These are biennial weeds and the low-growing first-year plants present at this time are much more susceptible to herbicides compared with taller plants next spring.  Take advantage of this opportunity to apply herbicide to field borders, roadsides, fencerows, etc for control of these weeds.  We suggest using a mixture of glyphosate plus 2,4-D and/or dicamba.  Where the goal is not to kill grass, options include a 2,4-D/dicamba mix and Crossbow.

Weather Outlook

The outlook for Thanksgiving week is for a warm and rather dry week. A few showers are expected Friday with the best chances in the north and northeast part of the state. Normals are highs near 45-50 and lows near 30 for this time of the year. Temperatures will average about 10 degrees above normal this week.

The last week of November and the start of December will have a return toward normal or just slightly above normal temperatures, but it will feel chilli compared to this week. There will also be a storm system with some rain, especially around the middle of the week (November 27-29).

December looks to be more active than the quiet November was. We expect temperatures to be close to normal and rainfall close to normal in December. There is a low chance of above normal rainfall in December.

The outlook into winter is for a bit wetter than normal with temperatures not too far from normal though they may average a bit above normal, but not nearly as warm as last winter with a record warm period.

We also added some new features to the NOAA National Weather Service Ohio River Forecast Center webpage for Flood, Drought and Seasonal Outlooks. Depending on what is happening, you may want to check them out. They let you know what is happening and what to expect.

Nutrient Management Plan Development Workshops Announced

Nutrient management plans developed to meet Natural Resource Conservation Service (NRCS) EQUIP program criteria can be developed by Certified Crop Advisors in the State of Ohio as a service to their farm clientele. Nutrient management plans take soil fertility recommendations one step further and start to assess the environmental concerns of field sites to nutrient runoff/loss via nutrient indexes plus assessing erosion and other resources concerns on the farm. Ohio State University Extension is offering workshops on Nutrient Management Plan Development to assist CCA’s in preparing their first plans.

The Workshops use an example farm to go through the process of developing a Nutrient Management Plan. The workshop utilizes two pieces of software that have been developed for putting these plans together plus Word Report Templates developed by Ohio NRCS. MapWindows GIS with MMP tools and MMP are the software products used. Both software products can be downloaded from Purdue University at the website

The workshops are day long programs from 9:30am until 3:30pm. It is highly suggested to bring along a laptop with software loaded since this is designed to be a hands on workshop using the program with an example farm. There is no cost to the workshops in winter 2012 and for 2013. A grant has been received by OSU Extension through USEPA GLRI Grant Number 00E01145 to provide these workshops and follow up work. Pre-registration is required. Registration links and more information can be found at
