GROUP O/4 RESISTANT WILD MUSTARD
(Sinapis arvensis)


Synthetic Auxins (O/4)

Canada, Manitoba
INTRODUCTION WILD MUSTARD
Wild Mustard (Sinapis arvensis) is a dicot weed in the Brassicaceae family.  In Manitoba this weed first evolved resistance to Group O/4 herbicides in 1990 and infests Cropland, Spring Barley, and Wheat.   Group O/4 herbicides are known as Synthetic Auxins (Synthetic auxins (action like indoleacetic acid)).  Research has shown that these particular biotypes are resistant to 2,4-D, dicamba, dichlorprop, MCPA, mecoprop, and picloram and they may be cross-resistant to other Group O/4 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.

MECHANISM

Hugh Beckie
Reduced binding to auxin-binding protein(s) is the probable basis for resistance.

ACADEMIC ASPECTS

Confirmation Tests

Field, Greenhouse, and Laboratory trials comparing a known susceptible Wild Mustard biotype with this Wild Mustard 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 O/4 resistant Wild Mustard indicate that the inheritance is determined by a one gene, dominant, nuclear trait.  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 O/4 resistant Wild Mustard from Manitoba please update the database.
