Regional Reports

June 30, 2000
Extension center educators, unit educators, and unit assistants in northern, west-central, east-central, and southern Illinois prepare regional reports to provide more localized insight into pest situations and crop conditions in Illinois. The reports will keep you up to date on situations in field and forage crops as they develop throughout the season. The regions have been defined broadly to include the agricultural statistics districts as designated by the Illinois Agricultural Statistics Service, with slight modifications:

· North (Northwest and Northeast districts, plus Stark and Marshall counties)

· West central (West and West Southwest districts, and Peoria, Woodford, Tazewell, Mason, Menard, and Logan counties from the Central district)

· East central (East and East Southeast districts [except Marion, Clay, Richland, and Lawrence counties], McLean, DeWitt, and Macon counties from the Central district)

· South (Southwest and Southeast districts, and Marion, Clay, Richland, and Lawrence counties from the East Southeast district)

We hope these reports will provide additional benefits for staying current as the season progresses.

Northern Illinois

Rain continued to fall in northern Illinois last week, and amounts received were from 1.5 to 4-plus inches. Needless to say, the excess rain has taken a toll on crops in areas subject to ponding. Many fields where ponding is a problem will have huge gaps with no crop except weeds.

There are some reports from northeastern Illinois that some beans still remain to be planted the first time, but the window for planting in our part of the world is rapidly closing.

Post-herbicide applications, mostly to soybeans, are being made as weather permits.

On the insect front, all is relatively quiet. It makes one wonder if this is the calm before the storm, or if mid- and late-season insect problems may actually not be a problem this year. Time will tell.

Some fields are still exhibiting signs of first-generation corn-borer infestations, so, even though the big picture for problems does not look bad, keep scouting; make sure your field is not the exception.

An in-depth Insect Management Workshop will be held July 20, 2000, at the Northern Illinois Agronomy Research Center near Shabbona, Illinois. The workshop will focus on current problems, predictive insect trapping, corn borers, rootworms, and leafhoppers. Even though problems with some insects have been minor this year, the information will help us to make management decisions for the next few weeks and next year. For more information, contact Dave Feltes at (309)792-2500. Registration deadline is July 13, and Extension Entomologists Kevin Steffey and Mike Gray will lead the program.

West-Central Illinois

· Heavy rains fell throughout most of the region, with reports of 5 inches or more in some areas. Some low, poorly drained areas of cornfields may soon exhibit nitrogen deficiency as a result of saturated soil.

· Corn is growing rapidly with some fields tasseled. Other fields will be in the reproductive stages very soon.

· Very little first-generation European corn-borer damage has been observed. Minor infestations, however, can be found burrowing into the leaf midrib.

· Grape colaspis adults are numerous in some cornfields and soybean fields

· Soybeans are growing rapidly. There are very few reports of problems other than rapidly growing weeds.

· Ergot has been detected in some grasses. It has been confirmed in some rye fields in Mason County.

· Wheat harvest is almost complete. The Orr Center in Pike County reported yields of 42 to 70 bushels per acre with an average of about 54 bushels per acre and a test weight of about 55 pounds.
