GROUP G/9 RESISTANT JUNGLERICE

EPSP synthase inhibitors (G/9)

Australia, New South Wales
INTRODUCTION JUNGLERICE
Junglerice (Echinochloa colona) is a monocot weed in the Poaceae family.  In New South Wales this weed first evolved resistance to Group G/9 herbicides in 2007 and infests Fallow.   Group G/9 herbicides are known as EPSP synthase inhibitors (Inhibition of EPSP synthase).  Research has shown that these particular biotypes are resistant to glyphosate and they may be cross-resistant to other Group G/9 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.

ACADEMIC ASPECTS

Confirmation Tests

Field, and Greenhouse trials comparing a known susceptible Junglerice biotype with this Junglerice biotype have been used to confirm resistance. For further information on the tests conducted please contact the local weed scientists that provided this information.
 
Genetics

Genetic studies on Group G/9 resistant Junglerice 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
 
Mechanism of Resistance

Studies on the mechanism of resistance of Group G/9 resistant Junglerice from New South Wales indicate that resistance is due to an altered target site.  There may be a note below or an article discussing the mechanism of resistance in the Fact Sheets and Other Literature
 
Relative Fitness

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 G/9 resistant Junglerice from New South Wales please update the database.
