INTERNATIONAL HERBICIDE-RESISTANT WEED DATABASE
Asian Copperleaf (Acalypha australis) is a dicot weed in the Euphorbiaceae family. In China this weed first evolved resistance to Group 14 (Legacy E) herbicides in 2011 and infests Soybean. Group 14 (Legacy E) herbicides are known as Inhibition of Protoporphyrinogen Oxidase
(Inhibition of Protoporphyrinogen Oxidase
). Research has shown that these particular biotypes are resistant to fomesafen and they may be cross-resistant to other Group 14 (Legacy E) 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 Copperleaf biotype with this Asian Copperleaf 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 14 resistant Asian Copperleaf 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 14 (Legacy E) resistant Asian Copperleaf from China please update the database.
