Issue No. 2/April 7, 2006

Still Looking for N Rate Cooperators
More volunteers are sought to take part in on-farm nitrogen rate trials. A modest payment will be provided to help make up for yield loss.

Videos from the 2006 Illinois Crop Protection Technology Conference Now Viewable from Our Web Site
There are 28 videos of presentations at January's crop protection conference available online. This year's videos are available free to the public (next year, a fee will be charged to those who didn't register for the conference); feedback about the concept is requested.

The Plant Management Network Is Worth Checking Out
The American Phytopathological Society makes four peer-reviewed journals available online for a modest annual fee.

Controlling Corn Soil Insect Pests
With the approach of corn planting, reminders are outlined about proper use of products for controlling soil insect pests. Producers who use such products are urged to include untreated check rows for comparison purposes.

Time for Alfalfa Weevils Is Drawing Near
The watch for alfalfa weevils will soon begin; details are provided on the relationship of degree-days to weevil development, correct insect identification, and scouting for alfalfa weevil larvae.

Do Aphids in Wheat Pose a Threat?
The aphids mostly commonly found in wheat in Illinois are described, along with the possibilities of economic yield losses and transmission of barley yellow dwarf virus.

It's Really a Matter of Time
The story of corn weed control in Illinois is being rewritten. With the adoption of glyphosate-resistant corn hybrids by many producers, the most critical difference to remember regarding weed control in corn and soybeans is that weed interference begins to affect yield sooner in corn.

Wheat Conditions Improve
Wheat development is on pace in most areas of Illinois. Nitrogen application and barley yellow dwarf virus are addressed.

Time to Plant Corn?
How does planting date affect corn yields? Research results from across Illinois are detailed. Planting early into poor soil conditions is likely to be counterproductive.

Regional Reports
A report is provided this issue for northern Illinois.
