Xtendflex, Liberty Link, and Widestrike/Roundup Flex Tolerance to Glufosinate and Metolachlor

Glufosinate tolerance of modern cultivars is suspected to vary.  The objective of this project was to evaluate these differences.  In three applications, up to the full labeled rate of glufosinate was applied to each cultivar.  Additionally, metolachlor was also added to some treatments.  Injury ratings and yield was collected at the end of the year.
