Mar 1, 2010, Source: University of Illinois Extension
As a new planting season gets under way, University of Illinois Extension Weed Specialist Aaron Hager cautions farmers to be aware of the differences between glufosinate and glyphosate, the active ingredients in two popular herbicides, before starting weed-control applications...
Will Glyphosate Fall to the Wayside as Resistance Grows?
Feb 15, 2010, BY FORREST LAWS
Glyphosate's become one of the most widely used herbicides, eclipsing even atrazine as the workhorse of chemical weed control. So could glyphosate become practically useless for all but a few niche markets in the next few years...
As Glyphosate Resistance Grows in Waterhemp, Soil Residuals May Help Control It
Feb 1, 2010, BY LIZ MORRISON
Mike Kuhns used a two-pass glyphosate program from the time he started growing Roundup Ready soybeans in 1996. For years, he applied 1.5 pints of glyphosate/acre....

Using a diverse herbicide application strategy may increase production costs, but a five-year Purdue University study shows the practice will drastically reduce weeds and seeds that are resistant to a popular herbicide...
Glyphosate Nonperformance Issues And Glyphosate-Resistant Biotypes
Jun 16, 2009, Source: University of Minnesota Extension
Glyphosate-resistant biotypes of giant and common ragweed and common waterhemp have been confirmed in Minnesota and are listed on the International Survey of Resistant Weeds Web site. Both species appear to be resistant to approximately four-times the labeled use rate of glyphosate (4X). In the short timeframe presented to us during the growing season, separating glyphosate nonperformance...
