There is not a lot of good news for the 2012 Illinois corn crop, but there has been recent rainfall in some places, and 46% of the crop was silking by July 1, far earlier than normal. Silks are abundant, and leaf color remains good in fields where plants have had enough water to get to a height of 5 ft. or more.
Although Goss’s wilt has not been detected in any corn samples submitted to the University of Illinois Plant Clinic this year, U of I plant pathologist Carl Bradley said that the disease may be present in the state. The disease is most likely to appear in fields that had severe Goss’s wilt in 2011 and that were planted to corn again in 2012.
Goss’s wilt is a bacterial disease of corn caused by the bacterium Clavibacter michiganensis subsp. nebraskensis (Cmn). It was detected in several Illinois counties in 2011.
The Spooner Agricultural Research Station was established in 1909 when the city of Spooner donated 80 acres of sandy loam soil to the University of Wisconsin. Farm Industry News photographer Mike Krivit traveled to the university to explore the variety of current research projects throughout the station, in addition to exploring the history of each program.
The Climate Corporation has published an Outlook Brief on the risk of early fall freeze for double-crop soybeans. This year’s abnormally early winter wheat harvest has raised the possibility of double-cropping for many growers who typically do not have enough time to bring a second crop to maturity before the first killing freeze of the fall. To help those growers decide whether to double-crop soybeans, The Climate Corporation has published an analysis of the earliest and median first freeze dates for nearly 1,000 locations across the Corn Belt....More

The event was held at the DLG International Crop Production Center, which was established in 2010 by DLG. Harald Teutenberg, head of communications for DLG, gives an overview of the event....More
An increase of just one degree in the average nighttime temperature during grain fill can cost an Illinois corn grower 3.6 bu. per acre, according to a recent study by The Climate Corporation. Its newly released Outlook Report quantifies the historical impact of nighttime heat stress on length of grain fill period and corn yield....More
The “Stand and Be Heard Anthem Singing Contest” by FMC has a new deadline. Participants can now enter through July 15.

Drought conditions around Indiana took a turn for the worse with 88 percent of the state now affected by ongoing dry weather, according to the latest U.S. Drought Monitor (http://droughtmonitor.unl.edu/DM_state.htm?IN,MW) released Thursday (June 14)....More
Historically, there has been little reason to worry about sulfur deficiency in Illinois, but University of Illinois assistant professor of crop sciences Fabián Fernández said that the frequency of sulfur deficiency in corn has recently increased.
With over six inches of rain in the past month in many parts of the Upper Midwest, farmers are enduring one of the wettest springs in years. Standing water, washout and hail damage have affected many areas. Some farmers have had to face replanting while others, with standing water, are concerned about the nitrogen that was lost....More
It is much easier to have a good finish when one gets off to a good start. The 2012 corn crop is certainly off to a great start. Our corn was planted early and avoided frost. Today it has a wonderful-looking, uniform stand of healthy plants. Our corn should pollinate before the July heat....More
To meet nitrogen level needs while avoiding weather-related pitfalls, growers should consider applying nitrogen (N) at multiple times. N may be applied in the fall, early spring (preplant), at planting and in-season (sidedress).
"The ideal circumstances are to do a split application," says John Shanahan, Pioneer Hi-Bred agronomy research manager.
This time of year – in-season – N applications allow for adjustments to planned nitrogen supply based on weather variations. ...More
The early spring and accompanying early planting, together with last fall’s dry conditions in many areas, may present unique management challenges to growers planning nitrogen (N) applications, according to agronomic experts at Pioneer Hi-Bred. These conditions can mean N loss and impact corn yields. ...More
Dry conditions and a record-setting heat wave have started to stress young, Midwestern corn plants, a Purdue Extension agronomist says.
According to the latest update of the U.S. Drought Monitor, Indiana and Ohio both have started to experience abnormally dry weather. Both also have endured several days of temperatures in the 90s. The combination can be extremely stressful to young corn plants, which need enough soil moisture to develop their root systems....More
Farm Industry News photographer Mike Krivit recently traveled through the Burnet and Polk counties of Wisconsin on his way home from a Memorial Day weekend trip, and he encountered some very soggy fields along the way. The area received torrential rain off and on throughout the weekend, which caused flooding in many of the fields.

University of Illinois crop sciences professor Emerson Nafziger was recently asked whether it is a good idea to plant soybeans into dry soil.
“It’s a fairly common question, especially with soybeans, because they’re more likely to be planted late, when soils are dry, and also because soybeans need to take on more water to germinate than corn seed does,” he said. Soybean seed also does not draw water quite as strongly as corn seed does.
In better-watered areas of Illinois where the corn crop is well established, the return of warm temperatures has caused very rapid growth. Corn planted in central Illinois in mid-March and not damaged by frost has accumulated about 900 growing degree days (GDD) by now and, thus, has reached stage V9 or V10, the point at which stem elongation accelerates. Such fields will likely show tassels by mid-June. Corn planted in early April has accumulated about 650 GDD and is at V7. Corn planted in mid-April is at V5, having accumulated approximately 520 GDD.
Emerald ash borer (EAB), the invasive insect that kills ash trees, continues to spread throughout the state. EAB Awareness Week, May 20-26, is the perfect opportunity to remind Ohioans of this pest's impact and their role in helping to limit its spread....More

It’s easy to feel dwarfed by the sheer size of BASF. Driving past BASF’s enormous chemical facility in Ludwigshafen, Germany, one can truly appreciate the immense size of the company. Here, BASF employs more than 33,000 of its overall workforce of more than 110,000.
BASF is the largest diversified chemical company in the world. The company develops and markets products that reach into just about every aspect of consumer life. On the company’s website, it lists 25 industries in which it provides products....More
Growers should begin scouting their emerging corn seedlings for signs of leaf feeding and cutting by black cutworms, according to coordinator of the Illinois Cooperative Agricultural Pest Survey Kelly Estes. Significant moth flights in late March and early April could have caused a significant presence of cutting-stage larvae in many areas of the state in the coming weeks.

“It’s a bit challenging to write a single article that encompasses the possible weed management scenarios of a cropping season that currently ranges from emerged corn up to the five-leaf stage, with many fields not yet planted,” said associate professor of weed science Aaron Hager. Here are a few items that might be of interest to weed management practitioners.
University of Illinois crop sciences professor Emerson Nafziger is concerned about frost damage to early-planted corn from the low temperatures in central and northern Illinois during the second week of April. He estimates that most of the corn planted before April 1 was up and growing by the time it frosted, and the earliest-planted corn was at or close to the three-leaf stage and suffered the most damage.
