Extension weed scientists at Ohio State University and Purdue University have recently reported confirmed cases of glyphosate-resistant giant ragweed in Ohio and Indiana. This will certainly be important to the growers who have this problem, especially in years when they are growing soybeans in these fields. This should be a warning notice to Wisconsin soybean growers as the complaints about giant ragweed continue to increase in Wisconsin.

Tim Jergenson, UW-Extension Barron County. The recent warm weather has led to concerns about stored corn grain beginning to mold in storage. Temperatures in Barron County have been above average for 31 of the last 52 days. These warm temperatures have caused some stored corn to begin to go out of condition. Farmers have only a limited number of options to counteract corn storage problems. The primary one is to check bins twice a week. To check grain, follow these steps:

Eileen Cullen, Extension Entomologist. In 2006, 106 Wisconsin soybean fields were monitored for variant western corn rootworm beetle abundance to help growers guide first year corn management decisions in 2007. Variant western corn rootworm beetle abundance and egg-laying in soybean fields, with potential root damage to first year corn in the same field the following year, present an economic risk to corn and soybean producers in the affected region(s).

Eileen Cullen, Extension Entomologist. Consultants at Agren, Inc. and the IPM Institute seek ten farmers to participate in a variant corn rootworm "proof of concept" pilot project. Fields having beetle counts under the treatment threshold of 5 beetles/trap/day are eligible to be enrolled in a pilot project. If the scouting recommendation is “do not treat” for corn rootworm and a farmer is uncomfortable following this recommendation, the farmer can participate in this “proof of concept” pilot project. It allows him/her to try the scouting recommendation on a trial basis without the fear of yield loss.

Eileen Cullen, Extension Entomologist. Soybean aphids have settled in for surviving winter in Wisconsin and the north central region. Wisconsin soybean growers and agricultural consultants have teamed up with University of Wisconsin Extension to monitor soybean aphid flights from June through October each year. Thanks to this partnership, Wisconsin now has 7 locations state-wide reporting to a Regional Soybean Aphid Suction Trap Network. How do the fall 2006 trap captures compare between states?

Eileen Cullen, Extension Entomologist. As the western bean cutworm becomes more firmly established as an economically important pest, corn producers will want to know how to manage it. Join the discussion on February 28th covering western bean cutworm biology and its economic impact, as well as management strategies and control options. Another email will be sent in the coming week with information on UW Extension County locations offering this course. Please watch for final location details in your area ...
