Fungicides efficacy/phytotoxicity tests of authorised herbicides (in pot and experimental field plots).

 Assessment of anticipated resistance risks for new herbicide molecules through:

 Baseline response test.

 Dose-response test.

 Confirmation/quantification of herbicide resistance in weeds (potted).

 Study of the mechanism responsible for resistance (laboratory):

 TSR: enzyme tests, sequencing of genes involved in resistance.

 NTSR: studies with metabolism inhibitors, expression studies.

 Use of molecular markers for early-stage weed characterisation.
