INTERNATIONAL HERBICIDE-RESISTANT WEED DATABASE
|
Spanish Pink Mustard (Erucaria hispanica) is a dicot weed in the Brassicaceae family. In Israel this weed first evolved resistance to Group B/2 herbicides in 2012 and infests Wheat. Group B/2 herbicides are known as ALS inhibitors (Inhibition of Acetolactate Synthase
). Research has shown that these particular biotypes are resistant to florasulam, flumetsulam, and tribenuron-methyl 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.

|
| Greenhouse, Laboratory, and None trials comparing a known susceptible Spanish Pink Mustard biotype with this Spanish Pink 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. |
| |
| Genetic studies on Group B/2 resistant Spanish Pink Mustard 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 |
| |
| 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. |
| |
| 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 Spanish Pink Mustard from Israel please update the database. |
