The Pulse Breeding Australia (PBA) Lentil Program is developing lines with tolerance to imidazolinone Group B herbicides which will expand the range of broadleaf weeds that can be controlled in-crop.

It is expected that improved tolerance to Group B herbicides will improve weed control options in the rotation by reducing damage from sulfonyl urea Group B herbicides when used in preceding crops.

Agronomic work is currently underway to validate the potential of this technology.
