Chemical FamilyExample HerbicideResistance Level
ImidazolinonesImazethapyr Intermediate Resistance < 10 fold
Pyrimidinyl benzoates Bispyribac-Na Not Determined
SulfonylureasChlorsulfuron Resistant > 10 fold
Triazolopyrimidine - Type 1 Chloransulam-methyl Intermediate Resistance < 10 fold
Triazolinones Flucarbazone-Na Not Determined

NOTE
Different Pro197 substitutions were present within populations, and therefore specific cross resistance patterns conferred by specific substitutions are confounded.
