NOTES ABOUT THIS BIOTYPE
April 2017 Update
20 verified cases. Most of these cases are seed samples sent by farmers or consultants on suspicion of resistance. They have been tested in pot experiments including a susceptible and resistant reference population. Tribenuron-methyl and florasulam have been applied in 4-6 doses. A survey on untreated plots in agricultural fields all over Denmark showed that T. inodorum was resistant in 1% of the fields.
