Other claims from this paper (10)
- Observation Pro-197 variants of Poa annua were resistant to thiencarbazone (resistance index 20.9-33.3).
- Observation Pro-197 variants of Poa annua remained sensitive to foramsulfuron alone (value 2.5-4).
- Intervention effect The foramsulfuron + thiencarbazone co-formulation showed reduced efficacy on Pro-197 variants of Poa annua compared with foramsulfuron.
- Observation Pro-197 populations showed no overall deviation from additivity in the herbicide interaction analysis.
- Observation Antagonism occurred in Pro-197 populations at reduced herbicide rates.
- Observation In docking models, most Pro-197 substitutions did not alter the ALS catalytic tunnel.
- Observation In docking models, foramsulfuron had a more favourable binding free energy than thiencarbazone.
- Observation In docking models, thiencarbazone showed fewer interactions and a less favourable binding free energy.
- Observation Trp-574-Leu variants of Poa annua showed cross-resistance to all treatments.
- Recommendation The foramsulfuron + thiencarbazone co-formulation should be restricted to fields without ALS-resistant weeds.
