HRAC GROUP 5 (LEGACY C1 C2) RESISTANT WILD RADISH
(Raphanus raphanistrum)


PSII inhibitors - Serine 264 Binders HRAC Group 5 (Legacy C1 C2)

Australia, Western Australia
INTRODUCTION WILD RADISH
Wild Radish (Raphanus raphanistrum) is a dicot weed in the Brassicaceae family.  In Western Australia this weed first evolved resistance to Group 5 (Legacy C1 C2) herbicides in 1999 and infests Lupins, and Triazine-tolerant canola.   Group 5 (Legacy C1 C2) herbicides are known as PSII inhibitors - Serine 264 Binders (Inhbition of Photosynthesis at PSll - Serine 264 Binders ).  Research has shown that these particular biotypes are resistant to atrazine, and simazine and they may be cross-resistant to other Group 5 (Legacy C1 C2) 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.
