INTERNATIONAL HERBICIDE-RESISTANT WEED DATABASE
Asian Mazus (Mazus fauriei) is a dicot weed in the Scrophulariaceae family. In China this weed first evolved resistance to Group 22 (Legacy D) herbicides in 2011 and infests Unspecified. Group 22 (Legacy D) herbicides are known as PS I Electron Diversion
(PSI Electron Diversion
). Research has shown that these particular biotypes are resistant to paraquat and they may be cross-resistant to other Group 22 (Legacy D) 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.

|Field, and Greenhouse trials comparing a known susceptible Asian Mazus biotype with this Asian Mazus biotype have been used to confirm resistance. For further information on the tests conducted please contact the local weed scientists that provided this information.
|Genetic studies on HRAC Group 22 resistant Asian Mazus have not been reported to the site. There may be a note below or an article discussing the genetics of this biotype in the Fact Sheets and Other Literature
|The mechanism of resistance for this biotype is either unknown or has not been entered in the database. If you know anything about the mechanism of resistance for this biotype then please update the database.
|There is no record of differences in fitness or competitiveness of these resistant biotypes when compared to that of normal susceptible biotypes. If you have any information pertaining to the fitness of Group 22 (Legacy D) resistant Asian Mazus from China please update the database.
