Issue No. 15, Article 6/July 6, 2007
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.
Corn and soybeans certainly have benefited from the near-ideal growing conditions over the past several weeks and appear very healthy. As of July 1, some early-planted corn in the region has begun to tassel but comprises only a small percentage of the total acres. Some fungicide aerial application is poised to begin this week, with more to follow. Producers are contemplating adding an insecticide to the application for protection against insect silk-clipping. However to date, rootworm beetle and Japanese beetle populations have not entered cornfields to a large degree. Japanese beetles are abundant on ornamentals in various areas of the region.
Extension educators have been monitoring western bean cutworm moth traps for several weeks. There have been no reports of western bean cutworm moth catches; however, the traps have attracted armyworm moths on a daily basis. Soybean aphids can be found in soybeans but are presently at very low population levels. Potato leafhopper populations are variable in alfalfa fields. Wheat harvest has begun in the southern portion of the region, with harvest to pick up next week.
We are enjoying very good growing conditions in most areas. Near-ideal temperatures and soil moisture levels have improved corn and soybeans dramatically. It should be noted that some locations still did not receive significant rainfall. Crops are under stress at those sites.
Japanese beetles continue to make their presence known. A few nutrient deficiencies and compacted areas are showing up.
Remember that the SIU Belleville Field Day is July 12, 2007, beginning at 9 a.m. The Belleville Research Center is located on IL Hwy. 161. This is the 41st annual tour.
