InCCA Conference Presentation Information
Weed Management in 2011 and Beyond
Production of Roundup Ready soybeans and utilization of no-till practices relies on extensive use of the herbicide glyphosate (Roundup). More than 90% of soybean acres in Indiana were planted with Roundup Ready varieties and no-till production practices were utilized on 60% of the soybean acres. However, adoption of no-till practices and increased reliance on glyphosate has resulted in a serious concern for long-term use of this valuable weed management tool. Glyphosate resistant weeds are commonly found in many counties. This presentation will discuss the latest techniques for management of glyphosate-resistant weeds including use of 2,4-D and dicamba in soybeans resistant to these herbicides.
