INTRODUCTION BALL MUSTARD
Ball Mustard (Neslia paniculata) is a dicot weed in the Brassicaceae family.  In Alberta this weed first evolved resistance to Group B/2 herbicides in 1998 and infests Cropland, and Wheat.   Group B/2 herbicides are known as ALS inhibitors (Inhibition of acetolactate synthase ALS (acetohydroxyacid synthase AHAS)).  Research has shown that these particular biotypes are resistant to metsulfuron-methyl and they may be cross-resistant to other Group B/2 herbicides.

The 'Group' letters/numbers that you see throughout this web site refer to the classification of herbicides by their site of action. To see a full list of herbicides and HRAC herbicide classifications click here.
