Regional Reports

June 2, 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

Dust storms, hail damage, and sandblasting, all thanks to the strong winds that blew in northern Illinois on May 24 and 25. Some replanting due to the hail damage.

Alfalfa harvest is moving ahead and a reminder for all to keep a watch on the regrowth for damage by weevil larvae and adults preventing greenup.

Stalkborers are on the move in all areas of northern Illinois.

Black cutworm larvae are still damaging some 3- and 4-leaf corn but not at threshold levels.

Sandhill cutworm reported and confirmed in Lee County, necessitating treating of some corn and replanting of some alfalfa/oats mix.

Bean leaf beetles continue to create problems, and in some fields, the numbers reported are high enough to justify treatments.

Seedling blights in soybeans are appearing in some areas.

Slowly but surely the crops are beginning to look good as the day and nighttime temperatures continue to warm.

Herbicide damage is necessitating replanting of some corn.

West-Central Illinois

· Heavy rain fell in most of the region during the week, with reports of up to 3 inches or more in some areas. Some hail damage on both corn and soybeans has been noticed.

· Grape colaspis and white grubs are the insects causing most of the damage at this time in both corn and soybeans. Some replanting of soybeans has occurred because of those two insects. There also has been a report of cutworm damage in soybeans.

· Seed rots and seedling blights can be found in some soybean fields but not severe enough for replanting.

· Postemergence herbicide applications on soybeans will begin as soon as soil conditions improve. Very few herbicide problems reported last week.

· Wheat streak mosaic is now evident in some fields in the southern part of the region. Dry weather caused injury in some wheat fields in western Illinois.

· Second cutting of alfalfa will begin soon for some producers. Potato leafhopper scouting should begin as temperature increases.

· In general, crop prospects at this time look excellent.
