GROUP B/2 RESISTANT PATERSONS CURSE
(Echium plantagineum)


ALS inhibitors (B/2)

Australia, South Australia
INTRODUCTION PATERSONS CURSE
Patersons Curse (Echium plantagineum) is a dicot weed in the Boraginaceae family.  In South Australia this weed first evolved resistance to Group B/2 herbicides in 1997 and infests Cereals, and Pastures.   Group B/2 herbicides are known as ALS inhibitors (Inhibition of acetolactate synthase ALS (acetohydroxyacid synthase AHAS)).  Research has shown that these particular biotypes are resistant to chlorsulfuron, and metosulam and they may be cross-resistant to other Group B/2 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 Patersons Curse biotype with this Patersons Curse 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/2 resistant Patersons Curse 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 B/2 resistant Patersons Curse from South Australia please update the database.
