Issue No. 9, Article 4/June 4, 2010
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.
Much of the area has received 1.5 inches of rain in the last week, limiting any fieldwork. High temperatures have increased the pace of crop development. It is getting hard to see the ground in many cornfields as the canopy closes. The corn crop continues to look good to excellent, though a few fields still look uneven as unstressed plants outpace their neighbors. There are some scattered reports of light cutworm activity along with reports of high populations of volunteer corn in winter-harvested fields.
There are few soybean fields that have still not been planted. Weed control is a high priority now in many soybean fields.
The main activities this past week have been finishing up planting soybeans, side-dressing nitrogen fertilizer, and applying postemergence herbicides. Corn and soybeans have really taken off with the warmer temperatures. Producers have been going nonstop in some areas side-dressing nitrogen, but nitrogen deficiency is evident is some fields. Scattered thunderstorms went through the area on Monday and Tuesday, with variable amounts; some areas received 1.5 inches. The rainfall was welcome as portions of the northern region were becoming dry.
Soybean planting is complete, though some fields are becoming quite weedy. With the dry weather last week, most first cutting of hay is complete.
Rainfall last week was sporadic and in some locations substantial. Other locations reported no rainfall, and planting/replanting continued until the general rains of June 2, which were widespread. The general area of Adams, Brown, Hancock, McDonough, Pike, and Schuyler counties has reported some of the highest replanting of corn ever for some producers. It was not unusual for seed dealers to have upwards of 20% of their seed corn sales replanted. More than one producer got the opportunity to know specific fields quite well, as they got to replant portions on three different occasions.
Soybean planting has progressed as rainfall has allowed. Some areas are half completed, others much less. Some replanting of soybean has occurred as well.
Wheat--what few fields exist--has pollinated or is pollinating.
Some producers have harvested a few fields of hay, but most have been concentrating on crop planting. Fescue and orchardgrass have both headed. Alfalfa is beginning to bloom.
