It should be an interesting year for pest management, with top contenders for headlines being soybean rust, western corn rootworms, soybean aphids, and glyphosate resistance.
Practice Safe S.E.X. (Sensible, Erudite [use of] Xenobiotics) in 2005
Many producers will be on edge about insect management in 2005. At the heart of this anxiety are rootworm-control problems many experienced in 2004 and the potential for a soybean aphid outbreak in 2005. We caution, though, that we see no reason to resort to short-term "solutions" that could result in more significant long-term problems.
IPM and IRM Perceptions and Considerations Regarding Corn Rootworms: Preliminary Results from a Distance Education Workshop
A preworkshop survey of participants in a multistate workshop assesses their current corn rootworm management knowledge and overall perceptions regarding IPM (integrated pest management) and IRM (insect resistance management) with respect to this insect. Preliminary results to a subset of questions asked.
Winter Temperatures Predict Promising Year for Corn Flea Beetles
Warmer temperatures in December, January, and February favor increased survivorship of the corn flea beetle and the bacterium it vectors.
Degree-Day Accumulations Behind Compared to One Year Ago
You can check on degree-day accumulations on insects and growing degree-days for crops at the Degree-Day Calculator (www.ipm.uiuc.edu/degreedays).
Black Cutworm Monitoring to Begin
Black cutworm trapping usually begins toward the end of March. Currently seeking volunteers who are monitoring or are interested in doing so.
New Publication on the Biology and Management of Horseweed (Marestail)
Glyphosate-resistant horseweed have been documented to the east and south of Illinois, yet none have been reported in Illinois. See http://www.ipm.uiuc.edu/weeds.html or http://weeds.cropsci.uiuc.edu.
Price Comparisons for Glyphosate Products
Essentially, to compare prices among glyphosate-containing products, we need to do a few calculations. Examples given.
