MULTIPLE RESISTANT CORN POPPY
(Papaver rhoeas)


Multiple Resistance: 2 Sites of Action

France
INTRODUCTION CORN POPPY
Corn Poppy (Papaver rhoeas) is a dicot weed in the Papaveraceae family.  In France this weed first evolved multiple resistance (to 2 herbicide sites of action) in 2016 and infests Cereals.  Multiple resistance has evolved to herbicides in the Groups B/2, and O/4.  These particular biotypes are known to have resistance to 2,4-D, iodosulfuron-methyl-sodium, MCPA, mesosulfuron-methyl, and metsulfuron-methyl and they may be cross-resistant to other herbicides in the Groups B/2, and O/4.

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

Greenhouse, and Laboratory trials comparing a known susceptible Corn Poppy biotype with this Corn Poppy 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 B, O/2, 4 resistant Corn Poppy 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 multiple resistant Corn Poppy from France indicate that resistance is due to unknown, and 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 multiple resistant Corn Poppy from France please update the database.
