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.
Field activity was observed in most areas the last half of last week until scattered showers occurred on Saturday evening and Sunday. Showers resumed again on Wednesday morning. Fieldwork focused on seed-bed preparation, anhydrous ammonia application, and corn planting.
Average alfalfa height is 4 to 6 inches, with no alfalfa weevil activity observed to date.
Extension educators monitoring black cutworm moth traps did not report any "intense" captures during the past week.
Dry conditions continue with 0.1 to 0.5 inch of precipitation this past week. Cooler temperatures have slowed growth somewhat. Wheat is generally approaching full flag leaf.
Cressleaf groundsel is in bloom. Dixon Springs reports giant ragweed has reached 6 to 8 inches in height, and rhizome johnsongrass is now over 6 inches tall.
A significant number of farmers have completed corn planting. Some have started to grab for the soybean bags. Concern is beginning to be expressed over dry soil conditions.
Alfalfa weevil has been the only major agricultural pest problem to date.
Rain fell in some areas, which interrupted planting. Other areas remain dry. Many farmers have finished planting corn.
Color of the early-planted corn has improved with warmer temperatures. Stands look very good, and few pest problems have been reported.
Soybean planting is just beginning.
Wheat fields look excellent, with no disease symptoms evident at this time.
Alfalfa and pastures are growing rapidly. Alfalfa weevils are present, but major feeding damage is not yet apparent.
