MULTIPLE RESISTANT BLACKGRASS
(Alopecurus myosuroides)


Multiple Resistance: 2 Sites of Action
ACCase inhibitors (A/1)
ALS inhibitors (B/2)

Turkey
INTRODUCTION BLACKGRASS
Blackgrass (Alopecurus myosuroides) is a monocot weed in the Poaceae family.  In Turkey this weed first evolved multiple resistance (to 2 herbicide sites of action) in 2008 and infests .  Multiple resistance has evolved to herbicides in the Groups A/1, and B/2.  These particular biotypes are known to have resistance to clodinafop-propargyl, and pyroxsulam and they may be cross-resistant to other herbicides in the Groups A/1, and B/2.

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.
