Training Session to Focus on Nutrient Management and Tough Weeds
"Nutrient Management in Corn" and "Managing the Tough Weeds of Northern Illinois" are the focus of a workshop for producers, agribusiness dealers, and crop scouts on August 10 in DeKalb County. Reservations are due by August 3.
Overview of Insects and Mites in Illinois Soybean Fields
A variety of insect topics are addressed: soybean aphid, twospotted spider mite, bean leaf beetle, western corn rootworm, and multiple pests, drought stress, and thresholds.
Assessing Product Performance for Corn Rootworms: Checks Are Vital
Producers may assume if lodging does not occur in corn that their method of corn rootworm larval control has worked satisfactorily. This assumption can prove wrong, especially in a dry summer such as this one.
Charcoal Rot Appears Early in Illinois Soybeans
Charcoal rot is a difficult disease to manage. Diagnostic characteristics and management suggestions are outlined.
Northern Corn Leaf Blight--Will It Be Common in Illinois Again This Season?
Because NCLB seems to be increasing and there should be plenty of the residue-borne inoculum in many fields from 2004, the disease should be considered when scouting cornfields.
Soybean Rust Update for Illinois
As of July 15, there were no observations of soybean rust on soybean, kudzu, or pea in Illinois. Scout fields frequently and check the Soybean Rust USA Web site for the latest reports and recommendations.
Late-Season Herbicide Applications in Soybean
Late-season applications of postemergence soybean herbicides are more commonplace, but they are not without risk. The risks are detailed here.
Corn and Soybean Crop Conditions--Time to Go to the Field
For both corn and soybean, it is important to get into fields soon to judge how plants have responded. The response to weather, especially when the weather is poor, will be somewhat different in every field. The wheat yield estimate for Illinois has been raised to 64 bushels per acre, only a bushel less than the record set in 2003.
Reports are provided this issue for southern and west-central Illinois.
