INTRODUCTION FIELD BINDWEED
Field Bindweed (Convolvulus arvensis) is a dicot weed in the Convolvulaceae family.  In Jordan this weed first evolved resistance to Group D/22 herbicides in 2011 and infests Dates.   Group D/22 herbicides are known as PSI Electron Diverter (Photosystem-I-electron diversion).  Research has shown that these particular biotypes are resistant to paraquat and they may be cross-resistant to other Group D/22 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.
