Armyworms Are Making Their Presence Known in Some Areas
Just this week, we began receiving reports of armyworms feeding in wheat fields and cornfields in the area of Bond, Clinton, and Montgomery counties. All reports of significant armyworm activity thus far have come only from those counties, so it is possible that the problem is localized. However, it is very important that everyone be on the alert for armyworms and their feeding injury.

Training Session to Focus on Managing Crop Production
A June 10 workshop in DeKalb County will address implications of corn and soybean growth and development stages plus results of current crop production research.

Wheat Twilight Field Day Set for June 23 at Shabbona
A free evening roundtable event will allow producers to ask questions and discuss wheat production and marketing with crop experts.

Insects Thus Far in 2004 (and Possible Coming Attractions)
A shortage of insect pests bodes well for producers, but significant problems can develop rather quickly. In corn, armyworm and European corn borer are the pests to keep an eye out for; in soybean, bean leaf beetle followed by soybean aphids.

A Brief Summary of Soybean Aphid News
It's not too early to prepare to scout for soybean aphids--early and often.

Remember to Scout Alfalfa Regrowth for Signs of Alfalfa Weevil Damage
Alfalfa weevils are still out there--keep scouting, and be mindful of management options.

First Potato Leafhoppers of the Year
Monitor alfalfa fields weekly for potato leafhoppers after the first cutting of hay. Economic thresholds and suggested insecticides are presented.

Illinois Seed and Seedling Diseases of Soybean
Injury symptoms and management options are outlined for seed and seedling diseases of soybean. Please send samples of soybean with seedling diseases to help illuminate which pathogens are most common in Illinois.

Not Quite Out of the Woods
Despite a very good beginning to the season, standing water and abnormal seedling growth are being experienced by some corn producers. Be aware that with warm soils, soybean seed can tolerate saturated soils for only a few days. Reports on growth conditions for field pea are sought. Wheat growers will be hoping for cool, dry weather to maximize grain filling.

Regional Reports
Reports are provided this issue for northern, southern, and west-central Illinois.
