This greenhouse experiment examined the response of homozygous susceptible and acetolactate synthase (ALS) inhibitorresistant plants from six Canadian kochia accessions with the Pro197 or Trp574 mutat...
Review: Confirmation of Resistance to Herbicides and Evaluation of Resistance Levels
Dose–response assay molecular-based assay quick tests sampling whole-plant assay
2015/12/21
As cases of resistance to herbicides escalate worldwide, there is increasing demand from growers to test for weed resistance and learn how to manage it. Scientists have developed resistance-testing pr...
Evolution of Resistance to Auxinic Herbicides: Historical Perspectives, Mechanisms of Resistance, and Implications for Broadleaf Weed Management in Agronomic Crops
Auxinic herbicides dominant trait evolution of resistance
2015/12/21
Auxinic herbicides are widely used for control of broadleaf weeds in cereal crops and turfgrass. These herbicides are structurally similar to the natural plant hormone auxin, and induce several of the...
Herbicides as Probes in Plant Biology
Molecular probe herbicides as tools chemical genetics proteomics
2015/12/21
Herbicides are small molecules that inhibit specific molecular target sites within plant biochemical pathways and/or physiological processes. Inhibition of these sites often has catastrophic consequen...
