Article Synopsis
- Indaziflam is a herbicide used to control annual bluegrass, but reports of poor effectiveness surfaced in the southeastern USA, leading to tests for potential resistance in these grass populations.
- Experimental results showed that while indaziflam worked effectively when applied before the grass emerged, it failed to control resistant bluegrass when applied after it had started growing, with notable differences in resistance levels compared to susceptible strains.
- This is the first documented case of resistance to indaziflam, highlighting the grass's resistance to multiple other herbicides as well, with further research needed to understand the underlying mechanisms of this multi-herbicide resistance.
