Managing invasive plants in fields enrolled in the CRP in Wisconsin
Due to the uniqueness in managing CRP fields, we have developed specific factsheets to help in developing management plans for these listed species in CRP fields (see links).

"Switch Date Decisions for Corn Hybrids", posted on Corn.Agronomy site
As the 2008 planting season progresses, growers are becoming increasingly concerned about yield loss due to delays. Yield penalties start to become significant after May 10-15, but what growers really need to worry about is the increased drying costs that will likely happen in the harvest season if planting is delayed much longer.

You Can’t Afford to Lose Feed Value This Year!
A variety of conditions have increased the value of feed this year. To demonstrate the economic significance of reducing dry matter loss in forage production, an analysis was conducted assuming good and fair management practices for alfalfa and corn forage for a 100 cow herd.

Bt Corn Insect Resistance Management Audio/Visual Resource Online
DTN and National Corn Growers Association (NCGA) hosted a free web seminar last week on Bt Corn Insect Resistance (IRM) and refuges. If you missed the DTN/NCGA online event last Friday, you can now view and listen to the program on Bt Corn IRM and refuges.

Have Corn Rootworm Eggs Hatched Yet in Wisconsin? – Not yet
This spring, ZedX, Inc. is providing our UW Madison Extension field crop entomology program with statewide soil temperature updates and estimated corn rootworm hatch and larval development progress.

Black Cutworms
Adult black cutworm moths migrate to the Midwest from the Gulf states each spring with the heaviest migration occurring in April and May.

Nominees Sought for the 2008 Wisconsin CCA of the Year Award.
In today’s agricultural industry where budgets are tight, timelines are short and days are long, it’s easy to forget to take the time to appreciate the work and valuable services provided by your fellow Certified Crop Advisors. We have all worked with an exceptional CCA, an individual who deserves special recognition. The state CCA Board and the international CCA program are asking you to take a few minutes to nominate that individual for the Wisconsin CCA of the Year Award.

Late-Planted and Replanted Corn Likely to Respond to Starter Fertilizer
Where corn planting has been delayed due to wet soils or where replanting is necessary due to poor stand establishment, use of starter fertilizer is important to increase yields and profits with these plantings. The increased probability of economic response to starter applies even on soils with excessively high P and K soil test levels.

Brush management guide updated
Within this guide is an overview of the various methods of management available for woody species including cultural, mechanical, and herbicidal techniques. In addition, this document summarizes information on the effectiveness of application methods with specific herbicides on common brush species of Wisconsin.

Insect Resistance Management and Refuge Requirements for Bt Corn
Planting Bt corn hybrids this spring? If so, growers are required by law to have an insect resistance management (IRM) plan in place. An IRM plan is implemented by planting refuge corn acres on each farm where a Bt corn hybrid is planted. Refuge corn acres are hybrids that do not contain the Bt insect trait used in the Bt planting.
