GROUP B/2 RESISTANT COMMON WATERPLANTAIN
(Alisma plantago-aquatica)

Inhibition of Acetolactate Synthase (B/2)

Turkey, Black Sea Trache

INTRODUCTION		COMMON WATERPLANTAIN
Common Waterplantain (Alisma plantago-aquatica) is a monocot weed in the Alismataceae family. In Turkey this weed first evolved resistance to Group B/2 herbicides in 2009 and infests Rice. Group B/2 herbicides are known as Inhibition of Acetolactate Synthase (Inhibition of Acetolactate Synthase ). Research has shown that these particular biotypes are resistant to azimsulfuron, bensulfuron-methyl, and penoxsulam 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.
