INTRODUCTION ASIAN COPPERLEAF
Asian Copperleaf (Acalypha australis) is a dicot weed in the Euphorbiaceae family.  In China this weed first evolved resistance to Group E/14 herbicides in 2011 and infests Soybean.   Group E/14 herbicides are known as PPO inhibitors (Inhibition of protoporphyrinogen oxidase (PPO)).  Research has shown that these particular biotypes are resistant to fomesafen and they may be cross-resistant to other Group E/14 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.
