Regional Reports

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:

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

Northern Illinois

Rainfall and winds of 60 to 70 mph went through the northern portion of the region on August 4, with Ogle and Carroll counties experiencing numerous power outages. Precipitation totals reported were 1 inch or more. Bill Lindenmier, Ogle County crop systems extension educator, reported that a few cornfields went totally flat, but overall corn held up fairly well.

Fungicide applications on corn have been common throughout the region during the last few weeks.

Extension educators monitoring western bean cutworm traps caught moths daily during the last three weeks in July, but captures have been minimal or nonexistent since August 1. Those monitoring soybean rust sentinel plots reported finding "a few" soybean aphids in sentinel plots the week of August 4, but 100% infested plants (20 plants inspected) were reported the week of August 11 in the sentinel plots in Whiteside and Lee counties. However, soybean aphid populations were below economic threshold levels. Japanese beetles are still present in soybeans, but populations have decreased from three weeks ago.
