HRAC GROUP 1 (LEGACY A) RESISTANT STERILE OAT

Inhibition of Acetyl CoA Carboxylase HRAC Group 1 (Legacy A)

France
INTRODUCTION STERILE OAT
Sterile oat (Avena sterilis ssp. ludoviciana) is a monocot weed in the Poaceae family.  In France this weed first evolved resistance to Group 1 (Legacy A) herbicides in 1996 and infests Wheat.   Group 1 (Legacy A) herbicides are known as Inhibition of Acetyl CoA Carboxylase (Inhibition of Acetyl CoA Carboxylase ).  Research has shown that these particular biotypes are resistant to fenoxaprop-ethyl and they may be cross-resistant to other Group 1 (Legacy A) 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.

GENERAL

Jacques Gasquez
We have no idea of the resistance mechanisms involved. The resistant populations are generally a mixture of Avena fatua and Avena Sterilis ludoviciana

ACADEMIC ASPECTS

Confirmation Tests

Field, Greenhouse, and Laboratory trials comparing a known susceptible Sterile oat biotype with this Sterile oat 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 HRAC Group 1 resistant Sterile oat 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

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.
 
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 1 (Legacy A) resistant Sterile oat from France please update the database.
