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.
Hot and dry conditions exist throughout the region. Rainfall would be most welcome. The major activities last week focused on postemergent herbicide applications in soybeans and harvesting the second cutting of alfalfa.
European corn borer activity has been observed, but no reports have been received of insecticide applications. Significant corn rootworm larvae feeding in first-year corn has been observed in a single field in southern LaSalle County. Japanese beetles have been observed in several fields feeding on giant ragweed and could pose a threat to corn silks during upcoming pollination. Alfalfa producers are encouraged to scout for potato leafhoppers particularly as the hot, dry weather continues. The cyst stage of soybean cyst nematodes has been observed in third- to fourth-trifoliate soybeans. Soybean manganese defiency has been reported as well.
Just a reminder that the annual Twilight Weed Control Tour at the University of Illinois Northern Illinois Agronomy Research Center in Shabbona will be held next Thursday, July 11, beginning at 5:00 p.m. University of Illinois weed scientists and graduate students will discuss some of the more than 40 weed control research studies currently being conducted at the center.
